S." or "No Body-Steering" bike. 81 00:05:09,364 --> 00:05:13,554 Let's see if would help us sort out the facts of steering. 82 00:05:13,765 --> 00:05:16,265 I've grafted an extra set of bars on this bike. 83 00:05:16,265 --> 00:05:19,175 The whole idead was to take the handlebars out of the equation 84 00:05:20,032 --> 00:05:23,482 to discover what so-called body-steering really does. 85 00:05:23,532 --> 00:05:27,282 The extra throttle on the top bars allows the driver to maintain speed. 86 00:05:29,300 --> 00:05:33,467 Even with massive shifts in body weight without any input to the handlebars 87 00:05:33,467 --> 00:05:35,687 the bike only vaguely changes direction. 88 00:05:36,434 --> 00:05:40,101 This will never get you through the corkscrew at Laguna Seca. 89 00:05:40,101 --> 00:05:41,734 Footpeg weighting is another myth. 90 00:05:41,734 --> 00:05:46,284 Even with his entire body weight on one peg, this bike merely varies off course 91 00:05:46,501 --> 00:05:50,221 and once its course is set, the pressure has even less effect. 92 00:05:50,535 --> 00:05:53,569 Good advice doesn't always put the rider in real control 93 00:05:53,569 --> 00:05:57,009 and can prevent us from properly to be able to do this. 94 00:06:00,103 --> 00:06:03,603 A little counter-steering with bar pressure gets the job done 95 00:06:03,603 --> 00:06:05,933 and puts the rider in control. 96 00:06:08,070 --> 00:06:13,137 Here we have managed a simple pointer on the tank to illustrate counter-steering. 97 00:06:13,137 --> 00:06:15,927 Let's take it for a ride and see what happens. 98 00:06:25,205 --> 00:06:30,695 See how the pointer shows the bars moving first to left and then right, and vice-versa? 99 00:06:31,572 --> 00:06:33,442 This is counter-steering. 100 00:06:33,506 --> 00:06:36,886 It is the only way to accurately steer a motorcycle. 101 00:06:39,973 --> 00:06:41,723 It really is simple. 102 00:06:42,207 --> 00:06:45,841 Just press on the bar and the bike responds instantly. 103 00:06:45,841 --> 00:06:48,961 That's all you do and it works all the time, everytime. 104 00:06:49,741 --> 00:06:52,301 Even with only one finger. 105 00:07:01,442 --> 00:07:03,809 The idea that we lean to steer comes from the fact that, 106 00:07:03,809 --> 00:07:07,776 when you lean right, you unconsciously pressure the right handlebar. 107 00:07:07,776 --> 00:07:09,810 And that counter-steers the bike right. 108 00:07:09,810 --> 00:07:11,670 Vice-versa for left turns. 109 00:07:12,543 --> 00:07:16,144 Lean steering is one of the myths of riding. 110 00:07:16,144 --> 00:07:21,577 Some believe body steering works because they can maneuver the bike with the hands off the bars. 111 00:07:21,577 --> 00:07:26,178 When we move our weight toward on the bike it actually creates a counter-steering action. 112 00:07:26,178 --> 00:07:27,748 Look at the pointer. 113 00:07:31,378 --> 00:07:35,379 Some riders are confused by how the steer a bike once they are in a turn. 114 00:07:35,379 --> 00:07:36,879 It's exactly the same. 115 00:07:38,846 --> 00:07:42,356 To tighten the turn, you press your inside bar. 116 00:07:42,446 --> 00:07:46,647 To widen your turn and bring your bike up, you press the outside bar. 117 00:07:46,647 --> 00:07:48,817 Counter-steering always works. 118 00:07:50,847 --> 00:07:57,297 Counter-steering is a piece of riding tech that will help you to improve your control in virtually every situation. 119 00:07:57,614 --> 00:08:00,524 Let's take a look at some other parts of riding. 120 00:08:02,782 --> 00:08:05,292 You guys really do have the cutting-edge of bike technology, don't you? 121 00:08:07,782 --> 00:08:09,682 Look at the size of that rear tire. 122 00:08:09,682 --> 00:08:12,132 Look at the size of those brakes. 123 00:08:12,549 --> 00:08:15,650 I bet you really can roll on when you need to, huh? 124 00:08:15,650 --> 00:08:19,783 The frame is stiff enough to handle all the breaking power and the grip of the tires. 125 00:08:19,783 --> 00:08:20,717 So how many ponnies does it have? 126 00:08:20,717 --> 00:08:21,757 Well over a hundred. 127 00:08:22,384 --> 00:08:26,051 Mine's around 150. They say it will do 180. 128 00:08:26,051 --> 00:08:26,971 It's impressive. 129 00:08:28,484 --> 00:08:32,564 Guess all that cutting-edge stuff can make a difference. 130 00:08:38,919 --> 00:08:41,552 But sometimes the cutting-edge cuffs the rider. 131 00:08:41,552 --> 00:08:46,362 What's needed is the riding technology to match the machine's technology. 132 00:08:46,819 --> 00:08:51,653 After over a century of development, motorcycles are trully precision cornering machines, 133 00:08:51,653 --> 00:08:53,553 but that doesn't eliminate rider error. 134 00:08:53,553 --> 00:08:56,943 What stops most riders from being able to use all of that potential? 135 00:09:43,792 --> 00:09:48,222 - Man, I was riding as hard as I could and the guy just disappears. 136 00:09:48,726 --> 00:09:50,166 - Yeah. Me too, man. 137 00:09:50,226 --> 00:09:53,706 - Hey is there anything on that twist 2 book he gave us about riding harder? 138 00:10:00,493 --> 00:10:01,063 - Here we go. 139 00:10:02,194 --> 00:10:06,074 To make real improvement, riders can expect to reach a high level of technical skill, 140 00:10:07,861 --> 00:10:10,711 but only if they ride at 75% of their limit. 141 00:10:10,794 --> 00:10:15,262 Everyone agrees that in some fashion, survival reactions... 142 00:10:15,262 --> 00:10:18,512 - Survival reaction? What's that? It's like, fear? 143 00:10:20,662 --> 00:10:21,112 - Yeah. 144 00:10:22,029 --> 00:10:27,189 Survival reactions or "S.R.s" are the ever present barrier to riders reaching their goals. 145 00:10:30,096 --> 00:10:35,456 - That's right, everytime I try to up the pace, I get myself in all sorts of problems. 146 00:10:36,864 --> 00:10:39,884 It's like I'm afraid to push my limits. 147 00:10:40,797 --> 00:10:43,237 But I'm not sure what I'm afraid of. 148 00:10:43,431 --> 00:10:46,741 - Me too, it's definitely my personal limit. 149 00:10:47,265 --> 00:10:49,945 I would describe it more like a mild panic. 150 00:10:54,399 --> 00:10:56,069 - Well, let's ride. 151 00:10:57,899 --> 00:10:59,169 - Where is my key? 152 00:11:01,966 --> 00:11:03,066 Where is my key? 153 00:11:03,400 --> 00:11:07,400 - What do you mean? - I never took it out but it's not here. 154 00:11:12,167 --> 00:11:14,267 It is an agreed upon fact 155 00:11:14,434 --> 00:11:19,754 our instinct of survival reactions, or "S.R.s", ruin a rider's hopes of being confident and in control. 156 00:11:43,504 --> 00:11:46,894 In riding, there are eight distinct so called survival reactions, or "S.R.s", 157 00:11:49,538 --> 00:11:52,388 and we can see all of them in this one incident. 158 00:11:53,171 --> 00:11:58,372 Immediately we see the rider trying to use body-steering into the turn when he should've counter-steered, 159 00:11:58,372 --> 00:12:00,362 so it starts out a little wide. 160 00:12:01,139 --> 00:12:04,806 If he would know how to steer the bike, this whole thing could've been avoided. 161 00:12:04,806 --> 00:12:08,416 Let's get back and see what other errors were made. 162 00:12:09,273 --> 00:12:13,340 He gets on the gas to stabilize the bike, but chops it mid turn. 163 00:12:13,340 --> 00:12:19,290 The bike stands up a bit and that's S.R. #1, chopping the gas from panic. 164 00:12:19,574 --> 00:12:22,441 Now he's counter-leaning against the angle of the bike. 165 00:12:22,441 --> 00:12:26,941 This increases bike lean angle, but doesn't tighten up the turn as he would hoped. 166 00:12:26,941 --> 00:12:28,921 This is another S.R. 167 00:12:29,542 --> 00:12:31,909 Now the bike is unstable and running wide, 168 00:12:31,909 --> 00:12:33,542 so he tightens his grip on the bars. 169 00:12:33,542 --> 00:12:35,352 Almost common S.R. 170 00:12:36,276 --> 00:12:38,876 None of this helped, he's running wide and panics. 171 00:12:38,876 --> 00:12:41,543 He is looking everywhere but where he should be ... 172 00:12:41,543 --> 00:12:44,053 ... around the turn, this is visual panic. 173 00:12:44,977 --> 00:12:48,243 His target locks on the very thing he doesn't want to hit. 174 00:12:48,243 --> 00:12:50,413 A S.R.? You bet. 175 00:12:50,677 --> 00:12:55,917 In a panic, we go where we look, he's steering directly towards the log where his attention is locked. 176 00:12:56,744 --> 00:12:58,314 S.R. #6 177 00:12:58,478 --> 00:13:02,628 With his attention toddling down he cannot steer effectively and becomes frozen on the bars. 178 00:13:04,012 --> 00:13:05,932 Yes, S.R. #7. 179 00:13:07,545 --> 00:13:10,079 He can't turn, so he jumps on the brakes. 180 00:13:10,079 --> 00:13:11,239 Our eighth S.R. 181 00:13:13,846 --> 00:13:18,447 His lazy steering started the whole mess, but when he chopped the throttle off it got worse. 182 00:13:18,447 --> 00:13:22,757 First let's take a look at throttle control and how it works. 183 00:13:31,715 --> 00:13:35,615 My bike went terrible on those turns back there, how is yours? 184 00:13:35,815 --> 00:13:40,775 Not too bad, but I didn't have as much grip as I would like. 185 00:13:41,049 --> 00:13:43,379 The roads must've been slippery. 186 00:13:43,582 --> 00:13:46,316 I think I need to play around with the suspension a little bit. 187 00:13:46,316 --> 00:13:46,883 You know how to do that? 188 00:13:46,883 --> 00:13:48,453 Yeah, but not enough. 189 00:13:48,616 --> 00:13:52,176 Hey, are there any suspension settings in that Twist of The Wrist II book the guy gave us? 190 00:13:54,917 --> 00:14:01,347 It says here that understanding the performance specifications of your bike is one step in reducing 191 00:14:01,351 --> 00:14:04,681 throttle control survival reactions, that detract from your riding. 192 00:14:06,118 --> 00:14:08,328 Sound 'bout right, what does that mean? 193 00:14:10,618 --> 00:14:15,152 Considering that most machines and the statical constant speed situation 194 00:14:15,152 --> 00:14:20,232 have roughly 50-50 weight distribution, we can begin to calculate the guidelines for correct throttle control for a turn. 195 00:14:23,720 --> 00:14:28,187 The fact the rear contact patch is larger the two tells the story. 196 00:14:28,187 --> 00:14:30,737 "Give me the more weight I can handle it." 197 00:14:30,854 --> 00:14:38,455 So, once in the corner a tire gets to shift 10 to 20% more load to the rear to give it its fair share of load. 198 00:14:38,455 --> 00:14:45,405 This we do with the throttle. Technically speaking, we want to slide .1 to .2 Gs of acceleration to accomplish that. 199 00:14:47,789 --> 00:14:52,879 Simply put, in a straight line, is the force generated by a smooth fifth gear roll-on 200 00:14:53,689 --> 00:14:57,709 in the 4 to 6 thousand RPM range on pretty much anything over 600 cc. 201 00:15:03,157 --> 00:15:06,297 That's not much acceleration, but it transfers the weight. 202 00:15:10,324 --> 00:15:15,714 Whatever the RPM range, we must maintain the weight transfer by continuing at throttle roll-on. 203 00:15:16,925 --> 00:15:19,195 Throttle control rule #1: 204 00:15:19,659 --> 00:15:25,989 Once the throttle is cracked open, it is rolled on evenly, smoothly and continuously throughout the remainder of the turn. 205 00:15:29,626 --> 00:15:32,393 This is not just a racing technique 206 00:15:32,393 --> 00:15:35,373 it applies to all corners on all motorcycles. 207 00:15:43,394 --> 00:15:46,428 Once the correct transfer of weight is achieved using the throttle, 208 00:15:46,428 --> 00:15:50,578 any big changes in the weight distribution will reduce available traction 209 00:15:51,562 --> 00:15:55,012 which is specially important in poor traction conditions. 210 00:15:56,396 --> 00:16:00,436 Once the bike is fully leaned over, violating rule #1 with poor throttle control 211 00:16:01,496 --> 00:16:05,476 will underweight or overweight that particular tire-bike combination. 212 00:16:05,763 --> 00:16:08,623 Hear again: even in poor traction conditions 213 00:16:08,730 --> 00:16:11,950 good throttle control gives maximum stability and grip. 214 00:16:13,297 --> 00:16:17,747 Slides are the negative result from rolling the throttle on and off. 215 00:16:18,398 --> 00:16:24,065 For track riding and racing, each throttle on-off or even just an hesitation will cost you time. 216 00:16:24,065 --> 00:16:26,865 At least a tenth of a second, about a bike lenght 217 00:16:26,865 --> 00:16:30,435 in a slow to medium speed turn. 218 00:16:38,233 --> 00:16:42,000 In higher speed turns, the same throttle error will cost you even more 219 00:16:42,000 --> 00:16:46,680 the effects of wind drag are substantial at higher speeds. 220 00:16:54,768 --> 00:17:00,308 - If the surface is slippery, do you want to overload the front or rear tires? 221 00:17:01,936 --> 00:17:02,386 - NO! 222 00:17:03,402 --> 00:17:04,152 - Correct. 223 00:17:04,569 --> 00:17:08,529 If you are rough or inconsistent with your throttle control, will it reduce traction? 224 00:17:10,870 --> 00:17:11,380 - YES! 225 00:17:12,937 --> 00:17:13,917 - Exactly. 226 00:17:14,637 --> 00:17:16,687 If you have good throttle control, 227 00:17:17,504 --> 00:17:21,474 will the weight be distributed properly on both the front and rear tire? 228 00:17:22,038 --> 00:17:22,548 - YES! 229 00:17:23,771 --> 00:17:28,121 - Exactly. Now, what is throttle control rule #1? 230 00:17:31,138 --> 00:17:34,818 - Once the throttle is cracked open, it is rolled on evenly, 231 00:17:39,806 --> 00:17:42,496 smoothly and constantly throughout the remainder of the turn. 232 00:17:46,873 --> 00:17:50,943 - Good. Now, repeat that to yourself one thousand times. 233 00:17:54,407 --> 00:17:59,475 - Once the throttle is cracked open, it is rolled on ... 234 00:17:59,475 --> 00:18:03,675 This rider is late on the gas and gets very hard, sudden acceleration out of the turn. 235 00:18:05,075 --> 00:18:08,876 This driver is trying for good throttle control and has nice, clean roll on, 236 00:18:08,876 --> 00:18:11,146 not the same fierce acceleration as the first guy. 237 00:18:12,043 --> 00:18:17,183 But what is the actual result in exit speed? Let's look at the radar. 238 00:18:20,077 --> 00:18:21,187 A huge difference. 239 00:18:23,510 --> 00:18:28,890 There are two circumstances under which you may violate throttle control rule #1. 240 00:18:28,911 --> 00:18:34,171 Let's take the point where you are bringing the bike up for the drive out of the corner as the first one. 241 00:18:34,211 --> 00:18:38,379 As the bike is bought up towards vertical, we can be more aggressive with the throttle. 242 00:18:38,379 --> 00:18:41,359 At some point you can pin it. 243 00:18:42,446 --> 00:18:45,946 Coordinating your throttle roll on with bringing up the bike, 244 00:18:45,946 --> 00:18:48,980 is how to maximize your drive out of any corner 245 00:18:48,980 --> 00:18:50,620 on any size bike. 246 00:19:02,914 --> 00:19:07,548 Most riders wait until the bike is nearly upright before they increase the roll on rate. 247 00:19:07,548 --> 00:19:10,238 The skill of it is in accurate timing of the pick up and roll on. 248 00:19:12,249 --> 00:19:13,939 What difference does it make? 249 00:19:16,116 --> 00:19:17,046 Quite a lot. 250 00:19:18,416 --> 00:19:22,550 The second exception to throttle control rule #1 is traction control. 251 00:19:22,550 --> 00:19:27,450 Riders can be far more aggressive with mid-corner and exit throttle. 252 00:19:27,450 --> 00:19:31,184 Double-apex turn to the other exception to the throttle control rule. 253 00:19:31,184 --> 00:19:33,351 So we're actually dealing with two turns, 254 00:19:33,351 --> 00:19:37,371 it's OK to roll off or stop the roll on between the two. 255 00:20:01,954 --> 00:20:04,144 - Hey, look, a CBR 1000. - And R6. 256 00:20:05,821 --> 00:20:10,288 - Look at the guy on the Repsol, he's not smooth with the gas. 257 00:20:10,288 --> 00:20:12,548 - I bet he's racer. 258 00:20:27,656 --> 00:20:29,096 - Told ya. 259 00:20:29,990 --> 00:20:31,610 - What are you looking at, kid? 260 00:20:31,657 --> 00:20:32,857 - Your tires. 261 00:20:32,857 --> 00:20:34,890 - What do you kids know about riding? 262 00:20:34,890 --> 00:20:39,040 - Once the throttle is cracked open, it's rolled on evenly, smoothly 263 00:20:41,524 --> 00:20:43,744 and constantly throughout the remainder of the turn. 264 00:20:45,358 --> 00:20:47,398 - How long have you guys been riding? 265 00:20:47,525 --> 00:20:48,795 - About three months. 266 00:20:49,458 --> 00:20:51,559 - Have you guys ever been at a riding school? 267 00:20:51,559 --> 00:20:54,809 - No, but we got this book this guy gave us. 268 00:20:55,692 --> 00:20:57,662 - Yeah, just keep reading it. 269 00:20:58,326 --> 00:20:59,426 - Come on, boys. It's time to go. 270 00:21:21,628 --> 00:21:25,795 - At some of those places I just couldn't help myself.

Is the bike happy? 285 00:22:12,767 --> 00:22:14,934 Are you happy when the bike is happy? 286 00:22:14,934 --> 00:22:16,084 Yes, yes and yes. 287 00:22:17,534 --> 00:22:19,801 In what range do we want the rear shock to operate? 288 00:22:19,801 --> 00:22:21,434 In the middle, of course. 289 00:22:21,434 --> 00:22:23,064 That's its most compliant range 290 00:22:23,768 --> 00:22:27,198 That's its sweet spot, just like the forks. 291 00:22:27,801 --> 00:22:32,069 Once you get back on the throttle, weight begins to transfer to the rear. 292 00:22:32,069 --> 00:22:34,269 The rear shock becomes our main concern, 293 00:22:34,269 --> 00:22:39,229 because we must now rely on it more for stability and traction. 294 00:22:43,203 --> 00:22:46,953 Contrary to popular opinion, getting on the gas hard makes the back of the bike rise, 295 00:22:47,737 --> 00:22:51,704 that applies to both chain and shaft drive bikes. 296 00:22:51,704 --> 00:22:55,604 As it rises, the rear suspension becomes stiff 297 00:22:55,604 --> 00:23:00,644 this results in the rear tire not being able to follow the road's surfaces well and the traction is reduced. 298 00:23:01,772 --> 00:23:07,262 This becomes abundantly clear when we look at front wheel speed compared to reader wheel speed on a straight. 299 00:23:08,072 --> 00:23:10,372 There is quite a bit of tire slippage. 300 00:23:10,372 --> 00:23:12,539 And look at rear suspension's position. 301 00:23:12,539 --> 00:23:14,109 Nearly topped out. 302 00:23:14,706 --> 00:23:17,206 Again, it isn't working well 303 00:23:17,206 --> 00:23:20,440 With good throttle control we get what the bike is designed to deliver, 304 00:23:20,440 --> 00:23:23,080 working suspension and optimum traction. 305 00:23:24,907 --> 00:23:27,074 Another down side of survival reaction #1, 306 00:23:27,074 --> 00:23:30,274 chopping the throttle, is reduce ground clearance. 307 00:23:30,274 --> 00:23:33,408 Not only does the front compress, so does the rear. 308 00:23:33,408 --> 00:23:37,078 Which further reduces your clearance. 309 00:23:37,842 --> 00:23:41,052 - Perfect examples. When the rider is hard on the brakes, 310 00:23:41,275 --> 00:23:45,175 the front-end wheel feels heavy. And the breaking... 311 00:23:48,710 --> 00:23:49,400 - Check it out. 312 00:23:55,644 --> 00:23:57,674 - Man, he is smooth. 313 00:23:57,977 --> 00:24:03,357 "Good throttle control allows the suspension to work properly and the bike is smooth." 314 00:24:05,011 --> 00:24:06,701 Let's see if we can catch him. 315 00:24:09,212 --> 00:24:12,832 Our new riders might've grasped the idea of good throttle control, 316 00:24:13,112 --> 00:24:15,622 but they certainly haven't mastered it yet. 317 00:24:47,515 --> 00:24:50,549 - Figured you guys would come this way. 318 00:24:50,549 --> 00:24:53,789 - Well, we figured out why you're so smooth. 319 00:24:57,783 --> 00:25:00,993 - They've got it. Your forks, shock 320 00:25:01,317 --> 00:25:05,187 and suspension settings create the potential for good handling. 321 00:25:05,351 --> 00:25:08,918 Your throttle control brings that potential into reality. 322 00:25:08,918 --> 00:25:12,218 Good throttle control has a major impact on slides. 323 00:25:12,218 --> 00:25:17,368 In controlled slides like this good throttle control maintains stability. 324 00:25:18,152 --> 00:25:23,372 In an unwanted or unexpected slide chopping it makes it worse. 325 00:25:24,252 --> 00:25:25,182 Watch this. 326 00:25:28,086 --> 00:25:32,816 Good throttle control, in reverse, can save you from the high side. 327 00:25:34,753 --> 00:25:37,443 A smooth roll off works much better. 328 00:25:37,454 --> 00:25:40,821 Practice your roll off as often as your roll on. 329 00:25:40,821 --> 00:25:44,054 When the time comes, it could make all the difference. 330 00:25:44,054 --> 00:25:47,321 Without getting into anything really nasty, like oil on the road, 331 00:25:47,321 --> 00:25:49,841 what are the usual conditions that activate our off the gas S.R.s? 332 00:25:53,689 --> 00:25:54,789 How about some of this? 333 00:25:57,422 --> 00:26:00,989 Water and sand are two big concerns for most riders. 334 00:26:00,989 --> 00:26:04,423 While you must not be aggressive with the throttle in situations like this, 335 00:26:04,423 --> 00:26:07,113 you certainly don't want to chop it either. 336 00:26:08,257 --> 00:26:10,990 What is your best bet if it's really slippery? 337 00:26:10,990 --> 00:26:14,960 Well, pick it up as best you can. The least lean angle, the better. 338 00:26:26,525 --> 00:26:31,226 - Looks like good throttle control solves many of our rider problems, doesn't it? 339 00:26:31,226 --> 00:26:31,736 - YES! 340 00:26:33,159 --> 00:26:37,026 There are many factors that affect what line a rider maintain through a turn. 341 00:26:37,026 --> 00:26:41,160 We will explore that later. The point we want to make now is this: 342 00:26:41,160 --> 00:26:43,960 no matter what line you take, high, low, middle, whatever, 343 00:26:43,960 --> 00:26:47,661 good throttle control is the gauge by which you can judge it. 344 00:26:47,661 --> 00:26:50,994 Riders are often confused about why the bike, initially, stands up 345 00:26:50,994 --> 00:26:54,424 and runs wide when they get off the gas mid turn. 346 00:26:56,328 --> 00:27:00,862 Once into your lean and the gas is rolled off, weight transfers to the front of the bike 347 00:27:00,862 --> 00:27:05,796 compressing the forks. That weight goes to the front tire and spreads out the contact patch. 348 00:27:05,796 --> 00:27:09,776 This creates additional drag on the patch to the inside of the center line of the bike, 349 00:27:10,430 --> 00:27:14,163 that drag counter-steers the bike up causing it runs wide. 350 00:27:14,163 --> 00:27:17,853 The whole thing can seem confusing, especially if the rider expects to 351 00:27:18,030 --> 00:27:22,031 tighten the turn when he rolls of the gas and he founds the opposite of that happening. 352 00:27:22,031 --> 00:27:25,165 A moment later, since the gas is off, the bike slows, 353 00:27:25,165 --> 00:27:29,265 leans further over and finally tightens up the turn. 354 00:27:29,265 --> 00:27:32,199 Applying brakes mid corner creates the same effect. 355 00:27:32,199 --> 00:27:36,809 When the weight transfers forward the result is the same, the bike stands up. 356 00:27:37,566 --> 00:27:41,876 A static throttle slows the bike as well. Again the bike tends to run wide. 357 00:27:42,633 --> 00:27:48,013 This effect is even more pronounced at higher speeds and steeper lean angles. 358 00:27:49,300 --> 00:27:53,500 Getting on the gas too hard too soon will also send the bike off line, wide. 359 00:27:57,534 --> 00:28:02,624 Getting on the throttle too slowly, makes the bike feel unresponsive. 360 00:28:06,935 --> 00:28:09,036 As we see here, with good throttle control, 361 00:28:09,036 --> 00:28:13,406 the bike looks and feels stable on its line and leaves the corner faster. 362 00:28:14,003 --> 00:28:18,870 Getting the feel for how much throttle the bike wants and needs to be stable, and have good traction 363 00:28:18,870 --> 00:28:22,037 and hold its line is the art of good throttle control. 364 00:28:22,037 --> 00:28:24,404 There are choices in lines, but the good ones 365 00:28:24,404 --> 00:28:27,374 follow the throttle control rule. 366 00:28:29,171 --> 00:28:32,705 - Jesus, I'm running wide on that exit almost every time 367 00:28:32,705 --> 00:28:35,675 And I'm following the throttle control rule. 368 00:28:45,006 --> 00:28:46,166 It doesn't make any sense. 369 00:28:47,173 --> 00:28:49,373 What does that Twist II book say? 370 00:28:49,706 --> 00:28:54,636 - You get on the gas as soon as possible. - I'm definitely doing that. 371 00:28:54,707 --> 00:28:58,474 But still I'm coming out, I can't hold my line. 372 00:28:58,474 --> 00:29:02,954 - We have minds holding our line, it's just unstable at the beginning. 373 00:29:04,741 --> 00:29:08,241 I'm not running wide on the exit, but my bike doesn't feel planted to, like, the apex. 374 00:29:12,709 --> 00:29:14,279 I do not know what we are doing wrong. 375 00:29:15,176 --> 00:29:16,966 - Let me take a look. 376 00:29:21,043 --> 00:29:22,253 A-ha, here we go. 377 00:29:23,110 --> 00:29:27,960 To meet the throttle control standard, steering is completed before you get it on. 378 00:29:28,077 --> 00:29:33,557 This doesn't mean at the apex, right before or just after, or any particular part of the turn, 379 00:29:34,411 --> 00:29:37,744 it means as soon as possible once the steering is completed. 380 00:29:37,744 --> 00:29:39,545 I never thought of that. 381 00:29:39,545 --> 00:29:42,445 - See, I was told you have to wait until you get to the apex. 382 00:29:42,445 --> 00:29:44,875 I've been scared to get it on before that. 383 00:29:45,845 --> 00:29:51,225 Let's look at all six of off-the-gas results and see why is so important to follow the throttle control rule 384 00:29:51,646 --> 00:29:56,836 and get back to the gas as soon as possible once bike has turned. 385 00:29:57,313 --> 00:30:01,213 1st Weight transfers forward changing our available traction. 386 00:30:02,180 --> 00:30:05,450 2nd We've lost our suspension's mid-stroke sweet spot. 387 00:30:06,014 --> 00:30:10,334 3rd The bike will tend to overreact to rough pavement and can become a bit twitchy. 388 00:30:11,481 --> 00:30:16,671 4th By creating some instability, the bike initially tends to run wide. 389 00:30:18,515 --> 00:30:23,935 5th As we saw before, we loose ground clearance on both ends of the bike. 390 00:30:25,983 --> 00:30:28,316 6th And lastly, the bike slows down. 391 00:30:28,316 --> 00:30:30,183 These are the six results you get 392 00:30:30,183 --> 00:30:33,803 From waiting too long to get back on the throttle. 393 00:30:33,883 --> 00:30:38,433 Getting back on the gas as early as possible solves all of this. 394 00:30:38,584 --> 00:30:40,551 Bike becomes planted and predictable, 395 00:30:40,551 --> 00:30:42,851 but can you get back on the gas too early? 396 00:30:42,851 --> 00:30:47,641 This rider got greedy with the throttle way too early, but the solution was correct 397 00:30:49,252 --> 00:30:51,785 roll off, reduce speed, repoint the bike and then roll back on. 398 00:30:51,785 --> 00:30:56,915 To add lean and throttle at this point of the turn is a common cause of crashes. 399 00:31:00,286 --> 00:31:02,316 But this is the way it really should be done. 400 00:31:15,654 --> 00:31:18,288 - He-hey, no more "chicken stripes"! 401 00:31:18,288 --> 00:31:22,322 - Yeah, I guess we both have a better understanding of throttle control. 402 00:31:22,322 --> 00:31:24,822 - And we're more confident on the level of the grip. 403 00:31:24,822 --> 00:31:27,989 - Right, throttle control is the secret to get the most out of your bike, but ... 404 00:31:27,989 --> 00:31:33,489 ... is one place you really need to go to see if you have it nailed. 405 00:31:34,623 --> 00:31:35,613 The track! 406 00:31:37,823 --> 00:31:39,803 I see you guys at the track. 407 00:32:21,861 --> 00:32:27,211 - I stayed with you all the way up to the fast turn, then you just pull away like a train. 408 00:32:30,862 --> 00:32:32,762 - That's because you were charging the turn. 409 00:32:32,762 --> 00:32:37,962 Charging turns is a common rider error. Being fearless with the speed and brakes coming in 410 00:32:37,962 --> 00:32:44,272 often adversely affects entry and mid turn throttle. 411 00:32:44,596 --> 00:32:46,276 - That was mistake. 412 00:32:57,164 --> 00:33:00,665 - All right, so when my arm is rising, I'm rolling on 413 00:33:00,665 --> 00:33:05,845 and when it's falling, I'm rolling off. So my left hand is telling you guys what my right hand is doing. OK? 414 00:33:19,467 --> 00:33:21,897 - I got it on that first turn ... 415 00:33:25,301 --> 00:33:27,341 ... But that double apex ... 416 00:33:34,468 --> 00:33:37,668 - Well, man... you're still charging the turns. 417 00:33:37,668 --> 00:33:41,235 - Yeah, you're right. That's S.R. #1 in another form, 418 00:33:41,235 --> 00:33:44,025 Brewing with gas going in there then coasting and losing too much speed. 419 00:33:49,803 --> 00:33:53,670 Charging your turns just messes your sense of speed. 420 00:33:53,670 --> 00:33:55,410 Let's take a look. 421 00:34:01,237 --> 00:34:05,207 Charging any turn tends to narrow our field of view. 422 00:34:05,238 --> 00:34:08,905 We'll be lose our reference points, it affects our sense of speed. 423 00:34:08,905 --> 00:34:11,585 This is one of our S.R.s. 424 00:34:13,972 --> 00:34:17,639 Our new rider is still charging corners and chopping the gas. 425 00:34:17,639 --> 00:34:21,419 That will cost him turn entry speed and a clean early roll on. 426 00:34:27,873 --> 00:34:29,407 This looks pretty rough. 427 00:34:29,407 --> 00:34:32,974 Even in slow speed situations, the throttle is our friend. 428 00:34:32,974 --> 00:34:35,264 Nothing else will stabilize the bike. 429 00:34:40,141 --> 00:34:42,608 Once you've mastered your throttle control S.R.s. 430 00:34:42,608 --> 00:34:47,938 you have taken a giant step towards control over the bike and confidence in yourself at any speed. 431 00:34:56,143 --> 00:34:58,543 Understanding your bike's needs and wants is important 432 00:34:58,543 --> 00:35:01,844 You don't have to be world champion to see throttle control 433 00:35:01,844 --> 00:35:06,484 optimizes your bike suspension, smoothes out rough surfaces, helps you hold your line 434 00:35:07,411 --> 00:35:10,381 and optimizes traction in practically every situation. 435 00:35:18,812 --> 00:35:21,712 - Man, this track riding is really hard work. 436 00:35:21,712 --> 00:35:25,972 - Yeah, I got a really bad formed pump, I can hardly hit the front brake. 437 00:35:27,646 --> 00:35:29,916 It's like riding motocross all over again. 438 00:35:30,313 --> 00:35:33,280 - We gotta get ourselves down on the gym and work out a little more often. 439 00:35:33,280 --> 00:35:33,730 - Yeah. 440 00:35:35,680 --> 00:35:38,181 My first reaction is to tell them both to relax. 441 00:35:38,181 --> 00:35:43,391 Let's take a close look at how excessive rider input creates instability and tires out the rider. 442 00:35:47,748 --> 00:35:49,482 Here a guy in holding on too tight 443 00:35:49,482 --> 00:35:52,932 causes to the rider to receive too much input. 444 00:35:53,449 --> 00:35:57,449 The tighter you hold on, the bigger the bumps seem. 445 00:35:57,449 --> 00:36:00,139 Small shakes from the front-end are amplified as well. 446 00:36:01,516 --> 00:36:03,950 Why are the bars moving? What are they searching for? 447 00:36:03,950 --> 00:36:09,230 They are trying to find the position that will stabilize the bike by maintaining the correct tracking of front and rear wheels. 448 00:36:11,584 --> 00:36:14,851 The bike does this without any help from the rider. 449 00:36:14,851 --> 00:36:17,951 If the rider could hold on tight enough to stop the bars moving, 450 00:36:17,951 --> 00:36:19,991 he would only amplify that wobble. 451 00:36:20,885 --> 00:36:26,025 The force he puts into the bars creates resistance and a plowing effect to the front tire's contact patch. 452 00:36:27,685 --> 00:36:33,115 Now the back of the bike wants to rotate around that resistance and the wobble becomes even worse. 453 00:36:36,353 --> 00:36:41,623 Setting a wheelie down cocked is an extreme example of this. 454 00:36:44,587 --> 00:36:49,257 Let's look again. When the front wheel is not in alignment with the bike's direction of travel, 455 00:36:49,421 --> 00:36:52,981 there's a huge resistance created at the front contact patch. 456 00:36:53,421 --> 00:36:57,451 The wheel immediately tries to realign itself with the bike's direction of travel. 457 00:36:57,888 --> 00:37:02,748 Take a look at the massive deformation in the front tire as it sets down. 458 00:37:02,956 --> 00:37:07,276 When the rubber springs back into alignment, the front end shakes. 459 00:37:07,856 --> 00:37:10,890 Look at the difference in front end shake the rider is creating, 460 00:37:10,890 --> 00:37:14,457 when he is too tight on the bars. Being stable on bike 461 00:37:14,457 --> 00:37:17,797 but loose on the bars reduces bike twitch. 462 00:37:27,758 --> 00:37:30,792 Holding on too tight transfers engine and road vibration 463 00:37:30,792 --> 00:37:34,572 to your hands and arms. Tiring them out and making them numb. 464 00:37:34,725 --> 00:37:37,292 This, in turn, causes you to hold on even tighter. 465 00:37:37,292 --> 00:37:41,982 The same elevated level of feedback can, again, easily distort your sense of speed. 466 00:37:44,293 --> 00:37:48,060 When the rider responds by tighten up on the bars, it gets worse. 467 00:37:48,060 --> 00:37:52,030 This is S.R. #2 once again, tightening on the bars. 468 00:37:55,361 --> 00:37:58,895 Over poor surface conditions, a rider who tenses his back, 469 00:37:58,895 --> 00:38:02,875 gets out harmony with his bike and will tend to bounce in the saddle. This causes extra suspension action. 470 00:38:06,662 --> 00:38:09,922 Your legs are terrific help to your bike's suspension in these situations, 471 00:38:09,962 --> 00:38:15,052 riding light in the saddle using your legs with the loosen slightly out back helps enourmously. 472 00:38:19,930 --> 00:38:24,190 Most riders become anxious about being blowed around by another vehicles, or the wind, 473 00:38:24,297 --> 00:38:29,364 and tighten on the bars. As the upper body is baffled by the wind, the bike 474 00:38:29,364 --> 00:38:34,734 is being steered by the wind. Ride loose like this and the wind's effect on the bike is reduced. 475 00:38:39,932 --> 00:38:42,299 Other key rider jobs are similarly affected 476 00:38:42,299 --> 00:38:44,532 by holding on too tight. 477 00:38:44,532 --> 00:38:49,742 Being stiff on the bike while riding through bumpy turns tends to turn the throttle on and off. 478 00:38:49,833 --> 00:38:54,753 Suspension and traction are affected because good throttle control is not maintained. 479 00:38:57,267 --> 00:38:59,727 Riding loose solves this. 480 00:39:04,935 --> 00:39:08,068 Riding rigidly can shake your helmet and blur your vision. 481 00:39:08,068 --> 00:39:12,335 The more you try to brace yourself and hold your head still, the more it shakes. 482 00:39:12,335 --> 00:39:14,936 This can even make your neck sore. 483 00:39:14,936 --> 00:39:17,276 Limber and loose is smooth. 484 00:39:18,936 --> 00:39:22,656 Do you ever find yourself making steering corrections while in the corner? 485 00:39:22,903 --> 00:39:28,343 This is another part of survival reaction number two, gripping the bars too tightly. 486 00:39:28,370 --> 00:39:31,004 As the bike runs wide, or feels like it's running wide, 487 00:39:31,004 --> 00:39:35,724 survival reaction number kicks in and steering corrections occur. 488 00:39:56,373 --> 00:40:01,393 This all makes the bike more unstable and it runs wide in the corner. 489 00:40:03,374 --> 00:40:07,041 How much actual bar pressure is needed to hold your line? 490 00:40:07,041 --> 00:40:11,881 As you can see, with good throttle control, none. 491 00:40:13,041 --> 00:40:17,401 - Check this out. I'm not helping the bike at all by holding on, the tighten I get on the bar is the worse it gets. 492 00:40:20,409 --> 00:40:25,669 I don't need to go to the gym to hold on tighter, I have to light my grip on the bars. 493 00:40:25,876 --> 00:40:27,916 I had all backwards. 494 00:40:28,543 --> 00:40:32,410 Like most avid cornering enthusiasts you tried to hang off. 495 00:40:32,410 --> 00:40:34,643 There are several key elements we'll cover on this. 496 00:40:34,643 --> 00:40:36,103 First, when do you hang off? 497 00:40:40,677 --> 00:40:45,611 One of the more common beginner errors is moving over into a hang off position right to the turning point. 498 00:40:45,611 --> 00:40:48,231 Notice the bike wiggling? 499 00:40:51,078 --> 00:40:55,379 The rule of thumb is to pre-position your hips, just before you roll off the gas. 500 00:40:55,379 --> 00:40:58,546 This method will reduce problems from unwanted 501 00:40:58,546 --> 00:41:00,526 handlebar and body inputs. 502 00:41:01,146 --> 00:41:05,780 The second novish error is hanging off too far. Enough is helpful 503 00:41:05,780 --> 00:41:09,810 too much is awkward and does more harm than good. 504 00:41:10,447 --> 00:41:14,527 Notice how stiff the rider is when off too far. 505 00:41:18,348 --> 00:41:22,815 One cheek off the seat is enough. These two simple rules will get you started. 506 00:41:22,815 --> 00:41:26,735 Hang off early and not too far. 507 00:41:29,016 --> 00:41:33,283 The opposite of hanging off is cross up. This reduces control, 508 00:41:33,283 --> 00:41:37,543 exaggerates lean angle and makes the rider twist and tight on the bike. 509 00:41:38,350 --> 00:41:40,850 With the hang off pole position control improves, 510 00:41:40,850 --> 00:41:45,860 lean angle is decreased and the rider is in alignment with his bike and relaxed. 511 00:41:47,284 --> 00:41:51,518 Compare the two, with the speed and line almost identical, 512 00:41:51,518 --> 00:41:54,488 look at the difference in exit lean angle. 513 00:41:58,685 --> 00:42:02,765 Less lean equals more throttle and better drive. 514 00:42:04,252 --> 00:42:07,019 Now let's compare straight-up riding with hanging off 515 00:42:07,019 --> 00:42:09,869 and see if there is a difference. 516 00:42:09,986 --> 00:42:12,026 Here he's riding straight up. 517 00:42:14,687 --> 00:42:17,387 Once again at nearly identical speed and line 518 00:42:17,387 --> 00:42:20,477 there is a measurable difference in lean. 519 00:42:23,888 --> 00:42:28,918 Body position on the bike can positively or negatively affect your riding. 520 00:42:29,622 --> 00:42:32,132 It could've gotten over sooner for this corner. 521 00:42:36,522 --> 00:42:39,842 Getting over before turning, he's smooth as silk entering the turn. 522 00:42:41,890 --> 00:42:46,910 Both errors here, moving over while turning and he's off too far. 523 00:42:48,157 --> 00:42:50,924 The problem is compounded when you lose connection with the bike. 524 00:42:50,924 --> 00:42:55,524 He's remediated that, now back up a bit... there he goes, his arms can now be loosed and relaxed. 525 00:42:58,625 --> 00:43:03,665 When the whole body position and turn entry package is done right it affords the rider the maximum of control 526 00:43:05,025 --> 00:43:06,895 with the absolute minimum of effort. 527 00:43:07,925 --> 00:43:11,955 Here is another view of a clean, loose run through a turn. 528 00:43:12,359 --> 00:43:16,193 The human machine works this way: when the lower body is unstable, 529 00:43:16,193 --> 00:43:19,153 we must rely on our arms and torso for support. 530 00:43:20,360 --> 00:43:24,127 Once the lower body is stable, we have our liberty to relax the torso 531 00:43:24,127 --> 00:43:25,877 and get great body position. 532 00:43:26,494 --> 00:43:30,794 Notice how much lower he can go without tension. 533 00:43:32,561 --> 00:43:37,701 Let's look at the difference between his moves on the bike when disconnected. 534 00:43:44,129 --> 00:43:47,029 And compare that to locked on to the bike firmly. 535 00:43:47,029 --> 00:43:49,719 Much more relaxed and in control. 536 00:43:53,930 --> 00:43:57,630 The cross up riding style looks even worse from on board. 537 00:43:57,630 --> 00:44:00,031 Everything about the rider is twisted and unnatural. 538 00:44:00,031 --> 00:44:03,591 Head, shoulders, even eye position strained. 539 00:44:06,298 --> 00:44:12,465 One last look at the difference between riding cross up and stiff on the bike... 540 00:44:12,465 --> 00:44:17,845 ... and riding in alignment. Well connected and loose. 541 00:44:26,367 --> 00:44:30,434 It is easy to see how we can create instability with the bike. 542 00:44:30,434 --> 00:44:33,767 What design features do sport and sport-touring bikes have, 543 00:44:33,767 --> 00:44:35,697 to help prevent that? 544 00:44:36,134 --> 00:44:38,901 Why do sport bikes even look the way they they do? 545 00:44:38,901 --> 00:44:41,802 High back seats anchor the rider more firmly 546 00:44:41,802 --> 00:44:46,292 reducing the need to hang on by grabbing the bars too tightly. 547 00:44:46,735 --> 00:44:47,202 Large tanks help provide a better perch on the bike 548 00:44:47,202 --> 00:44:52,232 Some riders use it for elbow or forearm rest during cornering. 549 00:44:55,236 --> 00:44:58,736 It can also provide a resting place for the upper torso. 550 00:45:00,737 --> 00:45:06,527 Knee cut outs on the tank side provide a more stable way to hold on, allowing the rider to use the bars less. 551 00:45:07,804 --> 00:45:10,238 Rear-set foot pegs are really important 552 00:45:10,238 --> 00:45:14,678 The give the rider a more stable perch for moving around on and steering the bike. 553 00:45:15,772 --> 00:45:21,202 If this bike had cruiser pegs like this, it would be unrideable. 554 00:45:22,472 --> 00:45:27,612 In fast turns, trying to ankle yourself firmly on the bike requires something to hold on to. 555 00:45:28,273 --> 00:45:32,003 Unfortunately, the inside bar is the handiest thing 556 00:45:32,240 --> 00:45:34,974 resulting in the rider pulling on it. 557 00:45:34,974 --> 00:45:40,124 This makes the bike go to the outer side of the turn, because you are counter-steering. 558 00:45:43,474 --> 00:45:46,975 Riffing the bike with one or both legs eliminates this problem. 559 00:45:46,975 --> 00:45:49,885 Resting an elbow on the tank can help. 560 00:45:50,942 --> 00:45:53,922 The hanging off style can have another unfavorable side effect. 561 00:45:55,042 --> 00:45:58,643 By pulling yourself from one side of the bike to the other, using the bars, 562 00:45:58,643 --> 00:46:00,403 you will make the bike wiggle. 563 00:46:03,476 --> 00:46:07,026 Anchoring yourself firmly on the bike and using your legs to move, 564 00:46:07,077 --> 00:46:11,107 reduces unwanted handle bar input and avoids the problem. 565 00:46:14,377 --> 00:46:17,411 Is a motorcycle truly out of control when it's sliding? 566 00:46:17,411 --> 00:46:22,021 How do you save it when the front or rear tire gives up traction? 567 00:46:22,178 --> 00:46:26,245 Why the fast guys always crash when their bikes slide? 568 00:46:26,245 --> 00:46:30,612 Well wiggles and shakes are distracting, there is a far more dramatic and deadly results 569 00:46:30,612 --> 00:46:34,482 from survival reaction number 2, that's being too tight on the bike. 570 00:46:35,046 --> 00:46:38,280 This is the stable position for a front wheel during the slide. 571 00:46:38,280 --> 00:46:42,010 What would happen if the rider resisted this movement? 572 00:46:43,080 --> 00:46:46,214 When you counter the front-end's natural attempt to stabilize the bike, 573 00:46:46,214 --> 00:46:50,594 you create resistance to the front contact patch, making the slide worse 574 00:46:51,181 --> 00:46:54,841 and turning into high sides like this. 575 00:47:13,783 --> 00:47:18,103 - My rear tire must've gone off, sliding at turn three. 576 00:47:19,184 --> 00:47:19,994 - Problems? 577 00:47:21,317 --> 00:47:26,027 - I didn't know you ride here. Yeah, sliding in turn three. 578 00:47:27,318 --> 00:47:29,152 - How is your throttle control through turn three? 579 00:47:29,152 --> 00:47:31,585 - Really good, I already worked that out. 580 00:47:31,585 --> 00:47:31,985 -Blame on the air pump? (?!) 581 00:47:35,186 --> 00:47:38,246 - Yeah, now that you mention it, I think I do. 582 00:47:40,519 --> 00:47:44,086 - Well, being tight on the bike can start little slides 583 00:47:44,086 --> 00:47:46,706 before you get anywhere near the limits of traction. 584 00:47:47,420 --> 00:47:49,400 - Really? It's not the tire? 585 00:47:50,087 --> 00:47:53,021 - Could you ride it just to see? 586 00:47:53,021 --> 00:47:56,861 - Sure. Always wanted to ride one of these. 587 00:48:15,556 --> 00:48:16,876 - So how was it? 588 00:48:17,523 --> 00:48:22,403 - Oh, the bike is great, thanks for the ride. Oh yeah... your tire is fine. 589 00:48:23,524 --> 00:48:26,014 - Guess I'm making it slide, then, huh? 590 00:48:26,491 --> 00:48:31,341 S.R. number two strikes again. Just too tight on the bars. 591 00:48:31,891 --> 00:48:34,271 - Try it again, I'll follow you. 592 00:48:36,192 --> 00:48:37,292 - Really? Thanks. 593 00:48:45,193 --> 00:48:50,053 While he may not be really fast yet, our new rider is making real progress. 594 00:48:57,694 --> 00:49:01,027 The three most commons reasons for front end slides are: 595 00:49:01,027 --> 00:49:03,367 One: over braking going into turns. 596 00:49:04,361 --> 00:49:09,031 Two: from overloading the front tire, this is called pushing the front end. 597 00:49:09,728 --> 00:49:14,338 The standard solution to a pushing the front end is getting back on the gas. 598 00:49:14,796 --> 00:49:19,576 And three: from slippery surfaces. Fighting the front will make you crash. 599 00:49:22,463 --> 00:49:26,953 Letting the bike do its own thing, relaxed on the bars, is the right choice. 600 00:49:27,097 --> 00:49:28,930 You are dangerous to yourself to the degree 601 00:49:28,930 --> 00:49:32,610 you let the survival reaction number two grip you on its claws. 602 00:49:33,964 --> 00:49:35,264 Take control by doing nothing 603 00:49:35,264 --> 00:49:38,414 let the bike stabilize itself. 604 00:49:41,532 --> 00:49:43,865 - Getting a lot of head shake over turn six. 605 00:49:43,865 --> 00:49:48,375 I think it's my shock or forks. Guess it could be a bad tire 606 00:49:50,399 --> 00:49:52,533 - Does it happen every lap? 607 00:49:52,533 --> 00:49:52,983 - Yeah. 608 00:49:54,633 --> 00:49:58,767 No, maybe once every two or three laps at first then it did it every lap. 609 00:49:58,767 --> 00:50:00,397 I had to pull in. 610 00:50:02,234 --> 00:50:06,401 - See, here it says bikes don't do anything every few laps, 611 00:50:06,401 --> 00:50:09,041 only riders do. 612 00:50:10,001 --> 00:50:14,901 So I bet if you loosen up on the bars, it will stop. 613 00:50:14,968 --> 00:50:16,528 - Yeah, I think you're right. 614 00:50:21,569 --> 00:50:26,199 We can contribute to or detract from the bike's stability by understanding its demands 615 00:50:28,103 --> 00:50:31,093 and eliminating any unwanted or unneeded inputs. 616 00:50:33,003 --> 00:50:33,537 Take braking. 617 00:50:33,537 --> 00:50:38,537 With the weight forward, stiff arms and up on the tank the bike stoppies. 618 00:50:38,537 --> 00:50:41,771 With less bar pressure and the rider stabilized by the tank 619 00:50:41,771 --> 00:50:43,761 the bike is more stable. 620 00:50:44,171 --> 00:50:49,661 Back in the seat with loose arms gives control the braking. 621 00:50:49,905 --> 00:50:54,505 Even with a severe lock up, control is much improved. 622 00:50:55,539 --> 00:50:58,449 An all too common error is twisting to the inside of the bike. 623 00:50:59,339 --> 00:51:03,139 He's trying to gain stability, but creates tension. 624 00:51:04,606 --> 00:51:08,607 Even if you don't hang off the bike, stabilizing your body is still important. 625 00:51:08,607 --> 00:51:14,087 Gripping the tank with one of both of your knees as you go into and through the turn is simple and efficient. 626 00:51:14,808 --> 00:51:16,741 The more firmly you anchor yourself, 627 00:51:16,741 --> 00:51:20,121 the easier it is to relax your torso and arms. 628 00:51:22,542 --> 00:51:26,512 For mid corner, suspension is set up for a given amount of weight forward aft. 629 00:51:28,176 --> 00:51:32,436 The bike can not compensate for you moving around on it. 630 00:51:34,009 --> 00:51:38,410 As we covered already, get into your forward-aft position on the seat early 631 00:51:38,410 --> 00:51:40,210 and stay there. 632 00:51:48,678 --> 00:51:54,108 Just to recap, your bike's suspension can be adjusted for a variety of road and track conditions, 633 00:51:54,545 --> 00:51:58,245 but you can not adjust it for excess rider input. 634 00:51:58,245 --> 00:52:02,415 By being loose, the rider allows the bike's suspension to perform at its best. 635 00:52:04,112 --> 00:52:06,452 The main points of rider input are: 636 00:52:06,979 --> 00:52:10,499 Hanging off too late creates instability. Get over early. 637 00:52:11,813 --> 00:52:14,247 Hanging off too far creates instability as well. 638 00:52:14,247 --> 00:52:19,507 Being disconnected on the bike looks like this. Locked on is better. 639 00:52:20,314 --> 00:52:23,704 Twisting on the bike. Going with the bike. 640 00:52:23,881 --> 00:52:28,391 The seat provides stability and so does the tank. Use your pegs. 641 00:52:34,749 --> 00:52:36,739 Riding stiff. Riding loose. 642 00:52:40,749 --> 00:52:44,139 Using the bars to hold on. Using the tank. 643 00:52:44,583 --> 00:52:48,693 Tight equals front end shake. Loose, stable. 644 00:52:49,784 --> 00:52:53,054 Crossing on the bike. Going with it. 645 00:52:53,184 --> 00:52:57,804 Tight, it slides. Loose, it recovers. 646 00:52:59,851 --> 00:53:04,011 Acceleration head shake. Acceleration stability. 647 00:53:06,352 --> 00:53:11,742 Breaking instability. Locked on in the seat gives good brake stability. 648 00:53:14,453 --> 00:53:16,773 - Yup, all those things have happened to me. 649 00:53:17,920 --> 00:53:20,553 - Yeah, you should just let the bike do the work. 650 00:53:20,553 --> 00:53:24,793 I'm causing my own handling problems and making myself tired. 651 00:53:26,954 --> 00:53:30,921 Stabilizing the bike is the rider's goal in any corner. 652 00:53:30,921 --> 00:53:33,455 Throttle error or entering a corner too fast, 653 00:53:33,455 --> 00:53:36,595 are two of our know enemies in getting that result. 654 00:53:36,788 --> 00:53:40,622 But perhaps the most important of all is your line through the turn. 655 00:53:40,622 --> 00:53:42,422 Having a poor line trough any corner, 656 00:53:42,422 --> 00:53:47,512 makes the riders job stabilizing the bike, with good throttle control, all but impossible. 657 00:53:49,823 --> 00:53:51,490 We've already explored counter-steering, 658 00:53:51,490 --> 00:53:55,857 and know it gives us effective and precise control of the bike's direction. 659 00:53:55,857 --> 00:53:59,777 But there are three underlying principles to steering that you must understand. 660 00:54:03,224 --> 00:54:06,604 There are three tools for use for executing our line. 661 00:54:06,691 --> 00:54:08,621 One, where you begin the turn. 662 00:54:23,893 --> 00:54:26,473 Two, how quickly you flick the bike over. 663 00:54:35,961 --> 00:54:38,421 Three, how far you lean it. 664 00:54:41,128 --> 00:54:44,098 Let's investigate the first one, where you start the turn, 665 00:54:44,195 --> 00:54:47,335 and see how it can affect your cornering. 666 00:54:52,096 --> 00:54:53,646 - Hey, you're doing good, huh? 667 00:54:53,929 --> 00:54:55,309 - Yeah, it's getting better. 668 00:54:57,563 --> 00:54:59,293 - Looks like it. 669 00:55:00,130 --> 00:55:04,500 I'm getting a feel for throttle control, but it's inconsistent. 670 00:55:04,931 --> 00:55:05,664 One lap I'm good, 671 00:55:05,664 --> 00:55:10,964 the next I'm storing the gas in the same turn. 672 00:55:12,431 --> 00:55:15,732 - I know what you mean, my line changes from lap to lap, 673 00:55:15,732 --> 00:55:19,162 so I don't know if it's the confidence to keep rolling it on. 674 00:55:29,200 --> 00:55:30,060 Gets to me. 675 00:55:30,600 --> 00:55:35,420 - Yeah, that happens to me too. It totally blows my confidence and I'm right back to rolling it off. 676 00:55:36,267 --> 00:55:38,767 I hate it when that S.R. happens. 677 00:55:38,767 --> 00:55:44,067 - It says here, that are eleven things that are influenced by where you turn into a corner. 678 00:55:44,935 --> 00:55:46,045 Eleven things... 679 00:55:47,401 --> 00:55:50,021 Guess what... both our problems are on that list. 680 00:55:50,402 --> 00:55:50,972 - Really? 681 00:55:52,769 --> 00:55:54,159 But what's the solution? 682 00:55:54,602 --> 00:55:57,269 What can you do to bypass these problems? 683 00:55:57,269 --> 00:55:59,769 The answer is too simple, find and use a good turning point. 684 00:55:59,769 --> 00:56:03,329 Finding a turning mark and using it will give you consistency. 685 00:56:06,703 --> 00:56:12,183 It helps to avoid problems like inconsistent lines and throttle errors. 686 00:56:12,271 --> 00:56:14,491 How can you find a good line? 687 00:56:14,804 --> 00:56:16,471 Once you establish a reference point 688 00:56:16,471 --> 00:56:19,961 the trial-and-error method will tell you what works and what doesn't. 689 00:56:21,505 --> 00:56:25,465 That tire snake on the pavement is a good reference point. 690 00:56:28,606 --> 00:56:32,996 He tries a latter turning, but that chops up his brake release. 691 00:56:35,606 --> 00:56:40,573 A little earlier runs in too wide and the throttle goes off and on. 692 00:56:40,573 --> 00:56:46,053 Right after it, he calls a clean line and, most importantly, the throttle control is great. 693 00:56:47,807 --> 00:56:50,241 - Let's look at some cornering theory. 694 00:56:50,241 --> 00:56:54,911 What kind of line will allow you to get back on the gas, most easiest for good throttle control throughout the corner? 695 00:57:00,209 --> 00:57:01,719 One that starts here? 696 00:57:03,342 --> 00:57:03,792 - No! 697 00:57:05,176 --> 00:57:07,266 - Good. One that starts here? 698 00:57:07,509 --> 00:57:07,959 - No! 699 00:57:08,810 --> 00:57:10,260 All right. How about this one. Starts here? 700 00:57:12,077 --> 01:54:25,357 - Yes! 701 00:57:13,043 --> 00:57:15,644 - Good. There are actually eleven ways 702 00:57:15,644 --> 00:57:20,544 your turn entry position or your turning point affects how you corner. 703 00:57:20,677 --> 00:57:24,647 First, let's look at your overall corner speed. 704 00:57:24,978 --> 00:57:27,978 He's taking an early turning resulting in an inside line. 705 00:57:27,978 --> 00:57:32,928 It's plenty fast coming in, but slow on mid turn and exit. 706 00:57:32,979 --> 00:57:35,579 Turning in later, trying to strike now the turn, 707 00:57:35,579 --> 00:57:37,559 allowing him to get back on the gas earlier. 708 00:57:39,679 --> 00:57:43,146 Your entry point has a huge effect on overall corner speed. 709 00:57:43,146 --> 00:57:45,713 While the low, inside entry had a high approach speed, 710 00:57:45,713 --> 00:57:49,273 it was slow on mid corner and exit. 711 00:57:52,714 --> 00:57:56,848 The higher, outside turn entry allows him to point the bike more towards the exit. 712 00:57:56,848 --> 00:57:59,818 Even before mid corner he is back on the gas. 713 00:58:00,315 --> 00:58:03,615 Now let's look at how entry point affects braking. 714 00:58:03,615 --> 00:58:06,015 Your beginning and ending brake points are both modified 715 00:58:06,015 --> 00:58:08,582 by the way you start your turn. 716 00:58:08,582 --> 00:58:12,416 On the low inside line you lean over longer and brake pressure is critical 717 00:58:12,416 --> 00:58:15,166 because it is easy to lock up the front wheel. 718 00:58:18,083 --> 00:58:20,650 On the later turn entry it's easier and safer, 719 00:58:20,650 --> 00:58:23,717 because more braking is done with less lean angle 720 00:58:23,717 --> 00:58:25,584 and it, most often, is completed earlier 721 00:58:25,584 --> 00:58:28,214 allowing the rider to get back on the gas. 722 00:58:31,385 --> 00:58:36,815 This is a huge difference. If the pavement was slippery, which line would you choose? 723 00:58:37,085 --> 00:58:41,815 Finishing the braking earlier or later? Your turning point determines that. 724 00:58:43,752 --> 00:58:45,553 Let's follow him below the high line. 725 00:58:45,553 --> 00:58:50,573 He ends his braking just as he flicking it in and he gets a better drive. 726 00:58:53,587 --> 00:58:56,120 By the way, even thought it's usually a minor point, 727 00:58:56,120 --> 00:59:00,920 downshifting is another thing that is affected by way your turning. 728 00:59:21,023 --> 00:59:26,293 Of the key tools of turning, one is how quickly you can get the bike over. 729 00:59:26,923 --> 00:59:31,763 It's easy to see how the early and later entries compare in this regard. 730 00:59:33,357 --> 00:59:36,191 The low entry requires lazy steering. 731 00:59:36,191 --> 00:59:39,111 You can't flick the bike onto its line. 732 00:59:41,058 --> 00:59:45,338 The later turning allows for a decisive steering commitment to the turn. 733 00:59:47,892 --> 00:59:52,982 Mid corner and exit stability and speed start when the gas comes on. 734 00:59:52,993 --> 00:59:57,543 Watch both lines to see when the gas comes back on. 735 01:00:04,727 --> 01:00:07,561 Our later entry rider was able to get back on the gas 736 01:00:07,561 --> 01:00:11,101 thirty seven feet earlier, that's five bike lengths. 737 01:00:11,761 --> 01:00:15,628 Earlier on the gas means stability through more of the corner. 738 01:00:15,628 --> 01:00:18,695 Your turning position has an enormous effect on that. 739 01:00:18,695 --> 01:00:21,255 That's six points so far. 740 01:00:21,829 --> 01:00:24,396 A good drive off the turn is number seven. 741 01:00:24,396 --> 01:00:26,063 Low line entry checks your drive, 742 01:00:26,063 --> 01:00:29,613 because number eight on the list, lean angle, also comes into play. 743 01:00:32,763 --> 01:00:37,603 You will lean over further and longer from a low line entry. 744 01:00:47,931 --> 01:00:51,799 Seeing the line that's taking you too wide does not inspire confidence. 745 01:00:51,799 --> 01:00:55,289 Seeing one that points you forward up the road, does. 746 01:00:59,199 --> 01:01:04,329 Number ten is how much road you have at the widest point of your exit. 747 01:01:07,033 --> 01:01:09,543 On the street, the same principle applies. 748 01:01:10,034 --> 01:01:12,834 Staying in your lane through the middle and exit of the turn 749 01:01:12,834 --> 01:01:15,874 it's all easier with the latter entry point. 750 01:01:23,902 --> 01:01:26,335 This helps reduce panic and provides rider to the 751 01:01:26,335 --> 01:01:30,245 greater margin of error in regard to oncoming traffic. 752 01:01:33,703 --> 01:01:37,170 The eleventh and final aspect that is affected by our turn point 753 01:01:37,170 --> 01:01:39,750 is mid corner lean angle correction. 754 01:01:40,437 --> 01:01:43,670 While they may seen like fact of life, they are a common rider error 755 01:01:43,670 --> 01:01:47,880 that results from the same tech point: early turn entry. 756 01:01:52,671 --> 01:01:54,205 Throttle control rule number one: 757 01:01:54,205 --> 01:01:57,475 the clean, continuous, roll on is always easier 758 01:01:57,805 --> 01:02:00,495 once you have established a workable turn point. 759 01:02:00,772 --> 01:02:03,306 The single, biggest cause of S.R. #1, 760 01:02:03,306 --> 01:02:07,736 going off the gas when you should be rolling on, is a bad line. 761 01:02:09,873 --> 01:02:15,107 We now know all eleven aspects of your riding that are affected by your turn in point. 762 01:02:15,107 --> 01:02:17,340 Let's quickly reveal them. 763 01:02:17,340 --> 01:02:20,720 One, where the brakes go on. Two, where the brakes go off. 764 01:02:21,841 --> 01:02:26,911 Three, where the throttle comes back on. Four, where the bike is pointed once fully leaned over. 765 01:02:28,408 --> 01:02:32,728 Five, where you will finish the turn. How wide will you leave when at the exit. 766 01:02:33,609 --> 01:02:37,519 Six, where you will downshift. Seven, how much lean angle will you use. 767 01:02:39,409 --> 01:02:42,710 Eight, how much (if any) steering corrections you will make. 768 01:02:42,710 --> 01:02:46,620 Nine, how quickly or slowly you will have to steer the bike. 769 01:02:47,810 --> 01:02:50,477 Ten, how much speed you can approach the turn with. 770 01:02:50,477 --> 01:02:54,207 Eleven, how quickly or slowly the throttle may be applied. 771 01:02:56,744 --> 01:03:00,278 Good. Those are the eleven things affected by your turn in point. 772 01:03:00,278 --> 01:03:02,512 Now, let's look at how quickly you turn the bike 773 01:03:02,512 --> 01:03:04,842 and how that affects your cornering. 774 01:03:09,979 --> 01:03:11,789 How quickly do you need to turn? 775 01:03:14,279 --> 01:03:16,369 Not very quick in this situation. 776 01:03:20,213 --> 01:03:24,593 It would be silly to quick flick the bike when you don't need to. 777 01:03:28,348 --> 01:03:33,318 Here is the perfect flick rate. Being able to get a quick, clean flick has many advantages. 778 01:03:46,083 --> 01:03:50,283 How does the rate you flick the bike affect your line in any series of corners 779 01:03:50,283 --> 01:03:51,853 like these "s"s? 780 01:04:13,019 --> 01:04:18,509 This rider's turn right was too slow to get him on line to set up for the next corner. 781 01:04:18,553 --> 01:04:21,986 This rider makes the same approach, starts his turn at the same place 782 01:04:21,986 --> 01:04:25,820 and he's running the same speed and with the quicker flick. 783 01:04:25,820 --> 01:04:29,080 His setup for the next turn is a perfect line and will work exactly the same way for you. 784 01:04:38,155 --> 01:04:42,705 - Once you begin your turn, where do the cornering forces start to push you? 785 01:04:43,988 --> 01:04:46,355 - Outside or wide in turn. 786 01:04:46,355 --> 01:04:50,135 - Exactly. If this is your intended line, 787 01:04:53,223 --> 01:04:56,083 and you're lazy bringing the bike over, where will you go? 788 01:04:57,123 --> 01:04:59,157 - Outside or wide in the turn. 789 01:04:59,157 --> 01:05:03,590 - So, if you flick the bike a little quicker, would it get on that line? 790 01:05:03,590 --> 01:05:04,100 - YES! 791 01:05:05,657 --> 01:05:07,877 - Class, you are brilliant today. 792 01:05:11,058 --> 01:05:14,028 Since we don't like to run wide in turns and for a very good reason in situations like this one, 793 01:05:15,658 --> 01:05:18,528 we must continue to lean the bike further and further to make the corner. 794 01:05:20,992 --> 01:05:26,412 Lazy steering forces you to lean the bike more than it's necessary and you'll be lean over longer. 795 01:05:27,059 --> 01:05:28,399 Let's compare. 796 01:05:37,394 --> 01:05:40,161 The quicker flick brings the bike on to the desired line, 797 01:05:40,161 --> 01:05:42,381 no extra lean needed. 798 01:05:44,428 --> 01:05:47,261 Look how much space he has on the outside of the turn. 799 01:05:47,261 --> 01:05:50,495 That will come in handy on the street, in an emergency, 800 01:05:50,495 --> 01:05:53,465 or on the track for speed. 801 01:05:57,996 --> 01:06:00,796 And look at the difference in acceleration. 802 01:06:04,496 --> 01:06:08,406 - What are the immediate benefits of getting the bike turn quicker? 803 01:06:08,597 --> 01:06:09,817 - More control. 804 01:06:10,030 --> 01:06:14,570 - Yes, yes, that's true, but why do we have more control and confidence? 805 01:06:14,998 --> 01:06:17,831 - Early on the gas, better throttle control. 806 01:06:17,831 --> 01:06:19,101 - And better traction. 807 01:06:19,398 --> 01:06:21,165 - It's not leaned over as long. 808 01:06:21,165 --> 01:06:22,615 - More choices on your lines. 809 01:06:22,632 --> 01:06:24,732 - You get on your line earlier. 810 01:06:24,732 --> 01:06:25,832 - Less lean angle. 811 01:06:26,865 --> 01:06:29,305 - I think you've got it. 812 01:06:39,633 --> 01:06:41,334 - Are they even in school? 813 01:06:41,334 --> 01:06:43,664 - Maybe that's a version of the pony school, huh? 814 01:06:53,635 --> 01:06:55,635 - I wish my mom would take to check when I was ten, 815 01:06:55,635 --> 01:06:58,075 I'd be world champion now. 816 01:06:58,102 --> 01:06:59,372 - Yeah, you're right. 817 01:07:00,502 --> 01:07:04,582 The approach speed and turn in point for both riders was very similar 818 01:07:05,036 --> 01:07:07,836 So what was the key difference that got this one through 819 01:07:08,103 --> 01:07:09,963 and put this one in the dirt? 820 01:07:10,970 --> 01:07:13,003 Let's look again. 821 01:07:13,003 --> 01:07:16,304 At this lazy steering right, even if he leaned over further, 822 01:07:16,304 --> 01:07:18,814 the results would have been the same or worse. 823 01:07:20,537 --> 01:07:24,338 The simple solution is flicking the bike quick enough to make the line. 824 01:07:24,338 --> 01:07:28,818 Now what would happen when they increase their turn entry speed? 825 01:07:30,738 --> 01:07:33,128 His results would just get worse. 826 01:07:34,839 --> 01:07:39,273 With the higher entry speed than before this rider still makes his line. 827 01:07:39,273 --> 01:07:41,340 It is quite simple. In turns like this 828 01:07:41,340 --> 01:07:45,260 as the speed increases, so must your flick rate. 829 01:07:47,273 --> 01:07:51,874 To have the confidence, good turn entry speed is nothing more or less than faith in your own 830 01:07:51,874 --> 01:07:55,374 ability to get the bike turn quick enough. 831 01:07:55,374 --> 01:08:00,341 OK, we want to able to turn the bike as quickly as possible for lots of reasons. 832 01:08:00,341 --> 01:08:02,271 Like accident avoidance, 833 01:08:04,942 --> 01:08:07,632 to not run wide in turns or off the road, 834 01:08:11,809 --> 01:08:17,079 avoiding being late on the gas and having excess lean angle, 835 01:08:23,744 --> 01:08:27,644 not to mention you will get a better drive. 836 01:08:27,644 --> 01:08:32,894 How do we make this possible? How do you become efficient at your steering? What works and what doesn't work? 837 01:08:33,711 --> 01:08:36,751 The plainly rotation of the bars looks like this. 838 01:08:37,112 --> 01:08:40,445 At a steeper angle like this, half your input into the bars 839 01:08:40,445 --> 01:08:43,595 goes straight down, this is a total waste of energy. 840 01:08:43,946 --> 01:08:47,376 At this angle you're still only 75% efficient. 841 01:08:48,446 --> 01:08:52,276 Here, your input is in line with bar rotation and is 100% efficient. 842 01:08:57,814 --> 01:09:03,014 This is another great example of how understanding the technology puts you in full control. 843 01:09:04,614 --> 01:09:08,404 A simple experiment will tell you if what a I say is true or not. 844 01:09:08,448 --> 01:09:11,715 Get forward on the bike and position yourself directly over the bars 845 01:09:11,715 --> 01:09:14,685 and try to push the bike down in to a lean. 846 01:09:15,449 --> 01:09:18,249 A lot of effort, but not much happens. 847 01:09:18,249 --> 01:09:23,119 All motorcycles work the same way. It's the horizontal rotation of the bars that gets the job done. 848 01:09:28,217 --> 01:09:29,650 A huge part of rider confidence 849 01:09:29,650 --> 01:09:33,500 is knowing you can quickly turn when you want to or need to. 850 01:09:33,884 --> 01:09:38,318 It's not about the kind of bike you ride, it's all about control. 851 01:09:38,318 --> 01:09:40,885 Some say flicking the bike too quickly is dangerous, 852 01:09:40,885 --> 01:09:45,795 or makes the bike unstable, but done correctly it is clean, smooth and efficient. 853 01:09:48,086 --> 01:09:51,386 - Any questions about flicking your bike? 854 01:09:51,386 --> 01:09:53,586 - When can't you lean the bike over quickly? 855 01:09:53,586 --> 01:09:55,966 - OK, let's figure it out. 856 01:09:56,586 --> 01:09:58,696 Could you quick flick your bike 857 01:09:59,487 --> 01:10:01,587 if the pavement or weather were slippery? 858 01:10:01,587 --> 01:10:02,037 - No! 859 01:10:03,554 --> 01:10:04,420 - Could you quick flick 860 01:10:04,420 --> 01:10:07,487 on cold tire or cold pavement? 861 01:10:07,487 --> 01:10:07,937 - No! 862 01:10:09,188 --> 01:10:12,221 - Could you quick flick with the hand full of front break? 863 01:10:12,221 --> 01:10:12,671 - No! 864 01:10:13,788 --> 01:10:17,255 - Could you quick flick with the tire that was brand new or not scrubbed in? 865 01:10:17,255 --> 01:10:17,705 - No! 866 01:10:19,789 --> 01:10:23,422 You! Could you quick flick with totally worn out tires? 867 01:10:23,422 --> 01:10:23,872 - No! 868 01:10:25,623 --> 01:10:27,990 - Do you need to quick flick your bike at low speeds? 869 01:10:27,990 --> 01:10:28,440 - No! 870 01:10:29,390 --> 01:10:30,890 - Now, do you get the idea? 871 01:10:31,723 --> 01:10:32,233 - YES! 872 01:10:33,257 --> 01:10:38,857 Our two new riders have come a long way towards understanding how the bike steers and where to turn it. 873 01:10:39,924 --> 01:10:44,058 Their confidence to lean the bike more is a direct result of that. 874 01:10:44,058 --> 01:10:49,488 Riders who understand this both look and feel in control of their bikes. 875 01:10:56,392 --> 01:11:00,126 - It's amazing. Once you understand the actual technology steering the bike, 876 01:11:00,126 --> 01:11:02,393 it totally changes your riding. 877 01:11:02,393 --> 01:11:06,583 - Yeah, completely changed. I feel in control steering the bike now. 878 01:11:07,593 --> 01:11:10,360 I know how quick to turn in, I know when and where I need to lean it... 879 01:11:10,360 --> 01:11:12,760 It's like I'm seeing the turns completely different now. 880 01:11:14,828 --> 01:11:16,761 My S.R.s are way quieter. 881 01:11:16,761 --> 01:11:18,441 - It's so simple. 882 01:11:19,095 --> 01:11:20,955 - Yeah, once you understand it. 883 01:11:22,928 --> 01:11:24,729 In double-apex turns like this one, 884 01:11:24,729 --> 01:11:27,662 things can, sometimes, feel a little busy. 885 01:11:27,662 --> 01:11:31,129 Trying to maintain a continuous throttle roll on only runs you wide, 886 01:11:31,129 --> 01:11:33,763 because it's really two turns. 887 01:11:33,763 --> 01:11:35,743 But the rider has more choices. 888 01:11:36,630 --> 01:11:38,663 Just roll the gas only a little bit and hold it there... 889 01:11:38,663 --> 01:11:41,283 Not horrible, but not stable either. 890 01:11:44,164 --> 01:11:48,874 Get on gas and then off to turn in for the second part of the turn then back to the gas... 891 01:11:49,398 --> 01:11:52,128 But that only chops it up, doesn't it? 892 01:11:52,131 --> 01:11:55,565 He could go in harder and brake a bit, then on the gas again, that could work... 893 01:11:55,565 --> 01:11:58,135 but he better be super smooth. 894 01:11:59,332 --> 01:12:01,242 OK, how do we do it? 895 01:12:02,466 --> 01:12:04,066 Timing is critical. 896 01:12:04,066 --> 01:12:07,226 Getting back into the throttle early stabilizes the bike. 897 01:12:07,466 --> 01:12:11,506 Then, mid corner, instead of rolling it off, he just stops rolling on. 898 01:12:11,567 --> 01:12:15,700 Here is where your body position comes into play in a big way. 899 01:12:15,700 --> 01:12:18,834 When you stop your roll on, some weight transfers forward. 900 01:12:18,834 --> 01:12:22,134 If you are low and to the outside of the bike, it corks around, 901 01:12:22,134 --> 01:12:26,864 tightening the bike's turning radius. That helps to get it pointed toward the exit without upsetting the bike. 902 01:12:27,635 --> 01:12:32,115 Look at how much earlier this rider is getting into his down and to inside body position. 903 01:12:38,003 --> 01:12:40,983 Here, we see an average hang-off position. 904 01:12:49,004 --> 01:12:54,084 Here is a more aggressive body position. Notice he is able to hold a tighter line. 905 01:13:00,905 --> 01:13:05,405 Now that's the "hook turn" technique, it can work in almost any cornering situation. 906 01:13:07,905 --> 01:13:10,706 On the road, this technique can be used quite effectively, 907 01:13:10,706 --> 01:13:13,276 if you find yourself running wide in a turn. 908 01:13:13,606 --> 01:13:17,226 Dropping to the inside and down position, plus a smooth roll off, one momentarily hesitation, 909 01:13:18,673 --> 01:13:22,473 not a chop off of gas tends to tighten the turn for you. 910 01:13:22,774 --> 01:13:25,744 And don't forget to look way you want to go. 911 01:13:28,141 --> 01:13:30,761 That's way better than the alternative. 912 01:13:33,341 --> 01:13:38,409 Here is a technique that can aid you greatly in your efforts to steer your bike accurately. 913 01:13:38,409 --> 01:13:43,619 We quite naturally push off our pivot from that trailing foot to produce maximum power and control. 914 01:13:45,309 --> 01:13:48,510 With that in mind, using the left leg to generate the power to 915 01:13:48,510 --> 01:13:50,370 press on the right bar, and vice-versa, is a logical step. 916 01:13:53,243 --> 01:13:56,813 It provides the rider with maximum stability on the bike. 917 01:13:56,844 --> 01:13:59,294 Stability equals control and strength. 918 01:14:00,377 --> 01:14:05,767 As we lock out lower leg into the bike from the foot peg to the tank we begin to create lower body stability. 919 01:14:07,411 --> 01:14:10,578 The next step is a slight tightening of the thigh muscles. 920 01:14:10,578 --> 01:14:15,279 This locks the pelvis in position, which, then, provides a stable base for the whole torso. 921 01:14:15,279 --> 01:14:20,613 With the torso stable, the rider's ability to apply pressure to the bars is vastly improved. 922 01:14:20,613 --> 01:14:22,483 We call this pivot steering. 923 01:14:22,813 --> 01:14:23,980 You might call it power steering, 924 01:14:23,980 --> 01:14:29,190 because once you master it, it feels so easy to steer the bike. 925 01:14:29,747 --> 01:14:33,481 Work on your quick turn. It pays huge difference in control 926 01:14:33,481 --> 01:14:37,571 and confidence in any situation, on any motorcycle. 927 01:14:39,315 --> 01:14:41,582 - Now that we know what the turn point is all about, 928 01:14:41,582 --> 01:14:44,662 how often do you get it just right? 929 01:14:46,182 --> 01:14:49,392 Is it usually too early or too late? 930 01:14:51,749 --> 01:14:52,789 - Too early! 931 01:14:53,883 --> 01:14:57,150 - That's right! Riders tend to turn in too early 932 01:14:57,150 --> 01:14:58,590 and there is a reason for it. 933 01:14:59,183 --> 01:15:02,317 - Would you like know how to change this part of your riding? 934 01:15:02,317 --> 01:15:02,767 - YeaWOOOEeahhh! :) 935 01:15:05,051 --> 01:15:08,118 Going where we look is an unfortunate survival reaction, 936 01:15:08,118 --> 01:15:11,198 in fact, it's S.R. #5. 937 01:15:14,852 --> 01:15:20,172 For example, if this rider looks at the inside of his next turn, he will go there. 938 01:15:30,453 --> 01:15:34,520 Once our attention becomes fixed on something, we steer towards it. 939 01:15:34,520 --> 01:15:38,700 In common parlance it's called "target fixation". And that's what causes you riders to take 940 01:15:38,987 --> 01:15:43,588 too early an entry into corners, all run wide, like this. 941 01:15:43,588 --> 01:15:46,988 We already know what the results of turning in too early are. 942 01:15:46,988 --> 01:15:51,488 Training yourself to look in, without turning it, is how we overcome this S.R.. 943 01:15:51,689 --> 01:15:53,909 We call it the "two-step" technique. 944 01:16:00,789 --> 01:16:04,923 It is also the key to finding a line that doesn't take you in too early. 945 01:16:04,923 --> 01:16:06,990 Even on unfamiliar roads. 946 01:16:06,990 --> 01:16:10,657 Your first step is estimate your turn in point on the road ahead. 947 01:16:10,657 --> 01:16:14,397 You don't know the road, so you're just establishing a temporary reference point. 948 01:16:14,958 --> 01:16:17,391 Step two is find your mid corner position. 949 01:16:17,391 --> 01:16:20,711 Where you quick the inside of the turn is your apex. 950 01:16:21,558 --> 01:16:26,392 The trick here is looking in to find it without turning the bike in at the same time. 951 01:16:26,392 --> 01:16:30,426 Now he looks in, but notice how he's staying wide in the corner. 952 01:16:30,426 --> 01:16:33,276 Now, would you be able to see a line from this position? 953 01:16:33,393 --> 01:16:33,673 No. 954 01:16:34,693 --> 01:16:36,793 Keep looking, but don't turn yet. 955 01:16:36,793 --> 01:16:37,653 How about from here? 956 01:16:38,160 --> 01:16:40,160 Not yet, but it's getting better. 957 01:16:40,160 --> 01:16:43,130 OK, now you can see your apex clearly. 958 01:16:43,627 --> 01:16:46,227 That is exactly where your turn in point should be. 959 01:16:46,227 --> 01:16:49,261 Nothing provides more confidence than knowing you're in a good line. 960 01:16:49,261 --> 01:16:52,931 And it does wonders for your throttle control. 961 01:16:56,928 --> 01:16:58,862 - Hey, you really started to get that bike turned. 962 01:16:58,862 --> 01:17:02,822 - Yeah, I just wish I was more consistent with my lines. 963 01:17:03,596 --> 01:17:05,396 Feeling kinda lost. 964 01:17:05,396 --> 01:17:08,596 - Well, you know there is four chapters in here about vision. 965 01:17:09,730 --> 01:17:14,720 There is a technique in one of them, it's called "the two-step" that's supposed to help. 966 01:17:16,497 --> 01:17:17,247 Two-step. 967 01:17:18,931 --> 01:17:24,011 Let's take a look and see if we can sort out his inconsistent lines. 968 01:17:24,431 --> 01:17:26,331 He run pretty wide on that pass. 969 01:17:26,331 --> 01:17:29,632 Let's see how he's timing his looking and turning. 970 01:17:29,632 --> 01:17:31,612 Big mistake, he's looking and turning. 971 01:17:32,199 --> 01:17:36,279 Now he's not running as wide, but it's another different line. 972 01:17:38,999 --> 01:17:43,649 The "two-step" visual technique solves more than just where to turn in to a corner 973 01:17:43,666 --> 01:17:46,576 it can also help with your consistency. 974 01:17:47,600 --> 01:17:51,330 In the end, your line through only'll be as accurate and consistent as your visual skills. 975 01:17:53,367 --> 01:17:55,968 Knowing exactly where you want the bike to go before entering 976 01:17:55,968 --> 01:17:58,598 using the "two-step" technique handles that. 977 01:17:59,701 --> 01:18:04,891 Applying the two-step technique allows the rider to gain space and time at the entry of the turn, 978 01:18:05,135 --> 01:18:08,336 the apex and pick up his next turn point accurately. 979 01:18:08,336 --> 01:18:11,669 Once you truly learn to lead with you head and eyes, you will able to 980 01:18:11,669 --> 01:18:14,529 enter all corners smoother, more accurately 981 01:18:14,703 --> 01:18:17,843 and, for track riding, usually faster. 982 01:18:17,903 --> 01:18:19,293 It's as good as it gets. 983 01:18:19,337 --> 01:18:22,737 Using the two-step turn entry technique, also helps combat the looking, 984 01:18:22,737 --> 01:18:25,137 going early S.R.s. 985 01:18:25,137 --> 01:18:26,717 By training yourself in this technique 986 01:18:26,737 --> 01:18:30,997 you will always be two visual steps ahead in every turn entrance. 987 01:18:33,705 --> 01:18:35,735 - Wow, what a great technique! 988 01:18:35,772 --> 01:18:38,392 I don't feel rush to the turn point. I mean, at all! 989 01:18:39,339 --> 01:18:41,659 - No, me neither! Hey, that two-step works! 990 01:18:45,039 --> 01:18:49,939 Hard braking can be both confusing and terrifying. No other control action on the bike 991 01:18:50,206 --> 01:18:54,107 can produce such dramatic results with so little effort. 992 01:18:54,107 --> 01:18:58,737 Most riders survival reactions run wide under heavy braking. 993 01:18:58,741 --> 01:19:01,491 Brake technology has come a long way. 994 01:19:09,342 --> 01:19:13,209 These improvements give riders far more choices on how to brake 995 01:19:13,209 --> 01:19:16,676 but the laws of physics still govern how hard we can use them. 996 01:19:16,676 --> 01:19:20,043 Brakes, just like the throttle, are lean angle sensitive. 997 01:19:20,043 --> 01:19:23,833 The more lean angle you use, the less you can use either of them. 998 01:19:23,943 --> 01:19:26,610 This brings up all kinds of questions about technique. 999 01:19:26,610 --> 01:19:28,880 Should I do all my braking straight up? 1000 01:19:31,344 --> 01:19:33,504 Or should I try other brakes into the turn? 1001 01:19:40,745 --> 01:19:44,655 Should I brake easy at first and hard at the end or the other way around? 1002 01:19:49,479 --> 01:19:53,319 How about easy, then hard and then easy again? 1003 01:19:56,713 --> 01:19:59,393 While braking, it's easy to lose sight of the real goal. 1004 01:20:00,547 --> 01:20:04,447 Getting your turn entry speed perfect is that goal. 1005 01:20:07,781 --> 01:20:11,221 With that in mind, which brake pressure sequence is best? 1006 01:20:12,081 --> 01:20:14,048 Turn entry speed errors are easiest to make 1007 01:20:14,048 --> 01:20:16,748 when you are hard on the brakes towards the end of braking. 1008 01:20:24,649 --> 01:20:27,849 In the fine art of braking, gradually trading the brake off 1009 01:20:27,849 --> 01:20:30,539 is the way to accurately find your entry speed. 1010 01:20:39,317 --> 01:20:42,618 Straight-up or trail braking. It's the exact same problem. 1011 01:20:42,618 --> 01:20:46,128 Maintain control of your entry speed. 1012 01:20:46,751 --> 01:20:48,318 Overbraking, S.R. #7, 1013 01:20:48,318 --> 01:20:51,552 often create other problems like poor throttle control, 1014 01:20:51,552 --> 01:20:53,542 and extra steering corrections. 1015 01:20:53,852 --> 01:20:55,902 Both unsettle the bike and can even cause excess wheel spin. 1016 01:20:57,552 --> 01:21:00,353 Panic braking in the middle of turns is something we try to avoid 1017 01:21:00,353 --> 01:21:02,283 because it stands the bike up abruptly. 1018 01:21:04,620 --> 01:21:08,130 Unconsciously, we apply pressure to the bars to maintain our line 1019 01:21:08,154 --> 01:21:11,054 That additional input is one of the primary reasons 1020 01:21:11,054 --> 01:21:13,564 for trail braking crashes. 1021 01:21:13,887 --> 01:21:18,987 Restraining bar flat out does not let the front-end fall off the road, which reduces traction even more. 1022 01:21:20,088 --> 01:21:24,122 Despite its dangers and drawbacks, trail braking is a useful tool. 1023 01:21:24,122 --> 01:21:29,182 Just imagine yourself leaning into a turn at 200mph with the brakes on like this. 1024 01:21:29,756 --> 01:21:34,976 If you have to break in a turn because of an emergency, like debris or surprise decreasing radius, 1025 01:21:35,223 --> 01:21:39,903 bringing the bike up as you do it your best hope for not washing out the front-end. 1026 01:21:44,324 --> 01:21:49,004 Simultaneous braking and downshifting smoothes things out and reduces distractions. 1027 01:21:49,791 --> 01:21:52,991 This helps you get your turn entry speed right. 1028 01:21:52,991 --> 01:21:57,381 Watch the timing of the the clutch and throttle action in slow motion. 1029 01:22:03,492 --> 01:22:08,712 Slipper clutch has seem to make this unnecessary, and modern technologies will probably make it an obsolete technique someday. 1030 01:22:11,793 --> 01:22:15,803 Too bad. It's quite fun when you get it right the old fashioned way. 1031 01:22:17,227 --> 01:22:19,327 Riders come up with all sorts of strange variations 1032 01:22:19,327 --> 01:22:21,628 to solve braking and downshifting. 1033 01:22:21,628 --> 01:22:23,628 He's downshifting first and braking later. 1034 01:22:23,628 --> 01:22:26,795 That's unnecessary engine abuse. Use the brake first. 1035 01:22:26,795 --> 01:22:29,595 Pads are cheap, engines are expensive. 1036 01:22:29,595 --> 01:22:33,362 Some just downshift and don't bother to use the breakes at all! In some situations 1037 01:22:33,362 --> 01:22:35,096 when the brakes aren't needed that's OK, 1038 01:22:35,096 --> 01:22:37,696 but again: pads are cheap. 1039 01:22:37,696 --> 01:22:40,429 Letting the clutch out slowly seems to solve it for some riders 1040 01:22:40,429 --> 01:22:45,629 but that's just extra wear and tear on the clutch and drive train. 1041 01:22:47,363 --> 01:22:52,743 Here he is revving the motor, but the clutch release is so slow he loses all the revs on his throttle blip. 1042 01:22:55,831 --> 01:22:58,465 Many riders use the sloppy method of downshifting. 1043 01:22:58,465 --> 01:23:01,675 No revs at all and a slow release of the clutch. 1044 01:23:06,032 --> 01:23:08,366 Getting too big a throttle blip over-revs the motor 1045 01:23:08,366 --> 01:23:12,636 and causes de bike to search forward with each gear change. 1046 01:23:15,633 --> 01:23:19,603 Another common error is over-revving and varying the brake lever pressure from the exaggerated wrist movement. 1047 01:23:21,267 --> 01:23:24,707 This is choppy and causes the bike to pogo. 1048 01:23:28,068 --> 01:23:32,508 Too early downshifting uses the engine as a break and over-revs it. 1049 01:23:33,468 --> 01:23:38,848 Not revving the bike between shifts and inconsistent brake pressure pogos the bike up and down. 1050 01:23:39,735 --> 01:23:42,365 Here, he's shifting and easing out the clutch slowly. 1051 01:23:43,036 --> 01:23:45,366 That takes time and attention. 1052 01:23:51,403 --> 01:23:55,843 He's revving it, but too high and still on and off the brake lever, pogoing the bike. 1053 01:23:57,904 --> 01:24:01,704 Making clean downshifts and maintain the control of the brake lever throughout will help. 1054 01:24:02,804 --> 01:24:04,871 Letting your fingers slight over the brake lever 1055 01:24:04,871 --> 01:24:08,371 while you control the pressure works really well. 1056 01:24:09,405 --> 01:24:12,505 Downshifting without the clutch is another way of handling it. 1057 01:24:12,505 --> 01:24:15,072 Careful timing of the throttle grip and the gear lever 1058 01:24:15,072 --> 01:24:19,502 makes it surprisingly easy and smooth, with or without a slipper clutch. 1059 01:24:20,339 --> 01:24:24,539 It may take some practice to make them perfectly smooth. 1060 01:24:26,173 --> 01:24:29,233 Elapsed time of throttle 1/8 sec 1061 01:24:57,476 --> 01:25:00,666 - Hey, you guys were looking pretty good out there in the corners. 1062 01:25:02,044 --> 01:25:04,977 - Thanks. You know, we learned a lot from your book. 1063 01:25:04,977 --> 01:25:07,177 - Ah, it's great. I'm really glad to hear that. 1064 01:25:07,177 --> 01:25:09,857 I did notice one thing, though. 1065 01:25:10,111 --> 01:25:13,601 - How you guys feel about your braking and downshifting? 1066 01:25:14,745 --> 01:25:16,305 Hmmm, I see... 1067 01:25:19,812 --> 01:25:23,612 So, clutch in, gas on and off, clutch in, gas on and off, 1068 01:25:23,612 --> 01:25:26,913 clutch out. Clutch in, gas on and off, clutch out. You got it. 1069 01:25:26,913 --> 01:25:31,847 Clutch in, gas on and off, clutch out. Just a little coordination point. It's really all it is. 1070 01:25:31,847 --> 01:25:34,213 - I can't believe how distracted I used to be. 1071 01:25:34,213 --> 01:25:36,814 - Absolutely, even after I improved my visual skills, 1072 01:25:36,814 --> 01:25:39,247 I was something rush at the turn entries. 1073 01:25:39,247 --> 01:25:41,648 - Well... so, I guess this is a pretty good example 1074 01:25:41,648 --> 01:25:44,618 of how a little coaching can really help. 1075 01:25:45,848 --> 01:25:49,882 Traction is the obvious limiting factor on our speed and direction changes. 1076 01:25:49,882 --> 01:25:52,015 We've explored how throttle control, rider input, 1077 01:25:52,015 --> 01:25:56,149 and surface problems can affect traction, but let's take a closer look. 1078 01:25:56,149 --> 01:25:59,199 A new rider's perception of traction is a little sketchy. 1079 01:26:01,250 --> 01:26:05,783 As we gain more experience with traction, our perception improves. 1080 01:26:05,783 --> 01:26:08,350 There are some classical approaches to understanding traction 1081 01:26:08,350 --> 01:26:11,417 used by average riders and pros alike. 1082 01:26:11,417 --> 01:26:16,567 They can give riders a new perspective on tire grip. It's a classic route to understanding traction. 1083 01:26:19,485 --> 01:26:22,118 Here's Keith's solution for understanding traction. 1084 01:26:22,118 --> 01:26:25,438 He calls it "the lean and slide bike". 1085 01:26:31,619 --> 01:26:35,999 About this time, most riders will chop the gas in panic. 1086 01:26:36,053 --> 01:26:39,220 It takes a lot more to lose traction than most riders think, 1087 01:26:39,220 --> 01:26:42,650 but there are situations you should be aware of. 1088 01:26:44,220 --> 01:26:49,190 Of course, if the tire was new and not yet scrubbed in, or too old, 1089 01:26:50,221 --> 01:26:55,111 too cold, tire pressure wrong, over or under inflated, 1090 01:26:55,922 --> 01:27:01,072 If you are riding on slippery surface or a polished surface, leaning the bike over too far 1091 01:27:03,089 --> 01:27:06,479 other mechanical problems, it would slide. 1092 01:27:07,223 --> 01:27:10,790 The slide bike helps train riders to avoid slide errors. 1093 01:27:10,790 --> 01:27:14,460 Watch what happens when he chops the gas. 1094 01:27:20,624 --> 01:27:23,791 As we've already seen, when rolled off and not chopped 1095 01:27:23,791 --> 01:27:26,541 it is far less violent. 1096 01:27:35,092 --> 01:27:39,759 Overriding the grip of new or cold tires is a classic novice riding error. 1097 01:27:39,759 --> 01:27:42,093 Even with relatively modest lean angles and speed 1098 01:27:42,093 --> 01:27:45,713 a cool tire on a cool day can surprise you when you first go out. 1099 01:27:46,760 --> 01:27:48,570 It doesn't take much to slide. 1100 01:27:48,660 --> 01:27:52,000 Tire grip and temperature are proportional. 1101 01:27:52,161 --> 01:27:55,994 A cold tire feels like it has maybe 25% its normal grip. 1102 01:27:55,994 --> 01:28:00,664 A warm tire on a warm day feels more like 75% or more right away. 1103 01:28:01,362 --> 01:28:04,702 Don't be a fool. Gradually bring the speed and temperature up. 1104 01:28:05,895 --> 01:28:08,475 Never trust the tires, trust yourself. 1105 01:28:09,096 --> 01:28:12,786 Learn to bring them up to temperature according to conditions. 1106 01:28:13,529 --> 01:28:15,696 In generally good conditions, as we have here, 1107 01:28:15,696 --> 01:28:18,497 Modern tires deliver excellent traction. 1108 01:28:18,497 --> 01:28:23,757 Good throttle control is the foundation that allows the rider to explore the limits of traction. 1109 01:28:26,264 --> 01:28:31,854 Even with good throttle control, a small slide can start or get out of hand when the rider is tense. 1110 01:28:32,631 --> 01:28:36,798 The rider's ability to be comfortable with traction limits depends upon having the key elements 1111 01:28:36,798 --> 01:28:41,108 of throttle control, rider input and visual skill. 1112 01:28:49,066 --> 01:28:52,067 Two other aspects of traction are important to understand. 1113 01:28:52,067 --> 01:28:55,434 The more lean angle you use, the less side grip you have. 1114 01:28:55,434 --> 01:28:58,004 The solution? Even when the rear tire is totally lit up, 1115 01:28:59,101 --> 01:29:02,441 bringing the bike up, into the slide, helps the rider maintain control. 1116 01:29:04,068 --> 01:29:06,601 The lean and slide bike is one of the training methods used 1117 01:29:06,601 --> 01:29:10,561 at Keith's school to help riders gain that confidence and the experience with traction. 1118 01:29:23,536 --> 01:29:27,336 All seven factors, visual skills, steering, turn points, 1119 01:29:27,337 --> 01:29:30,904 line, rider input, lean angle and picking up the bike 1120 01:29:30,904 --> 01:29:35,854 must be under the rider's control for him to be confident with the throttle and the traction. 1121 01:29:36,371 --> 01:29:40,971 New technology is great, but even with traction control and modern electronics, 1122 01:29:40,971 --> 01:29:43,605 the rider has to work his way up to using it. 1123 01:29:43,605 --> 01:29:45,839 Being in control of these seven factors 1124 01:29:45,839 --> 01:29:49,409 is the quickest and easiest route to confidence. 1125 01:29:52,706 --> 01:29:56,940 - I'm so stomped. This Twist II book really helped my riding out. 1126 01:29:56,940 --> 01:30:00,140 - Totally. Feels like I'm making improvement every ride I take. 1127 01:30:00,140 --> 01:30:01,474 It says there is no limits. 1128 01:30:01,474 --> 01:30:05,774 You know, I see more ways to apply this information every time I read this. 1129 01:30:06,641 --> 01:30:08,851 - How good we can actually get? 1130 01:30:10,208 --> 01:30:11,308 - Hey Will, how are you doing? 1131 01:30:11,308 --> 01:30:13,608 - Hey, you both look pretty good out there. 1132 01:30:13,608 --> 01:30:14,178 - Thanks. 1133 01:30:15,008 --> 01:30:19,575 - Yeah, but after watching you ride, you know, it just makes wanna kick it up a notch. 1134 01:30:19,575 --> 01:30:20,555 So how did you do it? 1135 01:30:21,209 --> 01:30:22,442 - I went to school. 1136 01:30:22,442 --> 01:30:23,302 - School? 1137 01:30:24,776 --> 01:30:27,609 - Let me ask you something, what do you do for a living? 1138 01:30:27,609 --> 01:30:29,169 - Well, I'm a doctor. 1139 01:30:30,010 --> 01:30:31,990 - I'm a software engineer, why? 1140 01:30:32,343 --> 01:30:35,410 - Well, did you wake up one day just knowing how to do your trade? 1141 01:30:35,410 --> 01:30:37,090 Or did you learn it by going to school? 1142 01:30:38,277 --> 01:30:42,047 - OK, point taken...
