  1. This weekend, it looked like the the later he was braking, the more he did it. The announcers said "even the riders don't know why they do it, but they say it just feels better" It looked like a few toughed their foot a couple times on the ground! :-o And it almost looked like it made Lorenzo (I think) lose it when it happened... it's odd, but it looks like more and more riders are doing it now.
  2. Well, at high speed, by the fact that it takes so much more energy to turn the bike, it's not possible to "flick" it over as quick, and if you watch the motogp riders in fast corners, it can seem that they are turning slow, but if you put an average rider on a bike and told them to steer at that speed, you'd seem them do it muuuuch slower. If you don't think they do it quickly, like Greg said, watch them in a chicane and see how fast they go from one side to the other. When I took STAR school with Jason Pridmore and rode on the bike for two laps, I was shocked how quick the chicane turn
  3. You dropped a unit in your first euqation here: (50 +400 +200)lb x 100 (mph) x5280 ft/3600sec=95333.3 lb ft/sec. Taking the numbers out leaves: Mass x Velocity = Force lbs x mph = HP But the equation is F=ma, or m X a = F: Mass x Acceleration = Force, so you should have lbs x (mph)^2 = (HPxtime)/Distance (Horsepower isn't equal to Force. Power is the product of force and distance over a period of time, or Power = (Force x distance)/time, so rewriting for Force: F = (Power x Time)/distance So far, we still haven't solved for speed or drag Think about it this wa
  4. The confusing part is keeping speed and acceleration separate. Speed is how fast you are going and acceleration is how fast your speed is changing. Your first sentence should really say "you can get more ACCELERATION from the horsepower you have, because you are pushing less weight." Put it this way; if you try and lift a 50 lb box very fast, you can do it at a certain rate. If you take lbs out of the box, you're not any stronger than you were before, but you can lift it faster, right? Mass/weight will affect your acceleration, but shouldn't affect your top speed much; only how long
  5. Ahh, here's the diagram I was looking for: (with that said, I would think sitting lower would make it easier to initiate the turn since the cg is closer to the axis of rotation). I've also seen similar stuff in some european mags
  6. Wouldn't that analogy be more applicable to making a slow u-turn with the bike, where you're not trying to add a large centrifugal force to get the bike to change course (turn instead of going straight)? The experiment I've done is sit on the supermoto and go around a corner, and then stand on it and go through the same corner at the same speed (as far as I can tell, the bike doesn't lean nearly as much if I take the corner standing up.)
  7. Yeah, there's a few things going on in this question. I suspect some people turn like that for the reason that hubbard stated; to actually turn later and take more of a "race" line. Some might be doing it to load the suspension up, and I suspect other people do it cause they are not comfortable turning a car (like when you see someone not going fast but turning a small car REEEALY wide for a turn that isn't that tight)
  8. I always thought a higher CG actually meant you had to lean the bike less, and that the purpose of hanging off was to move mass inward towards the radius of the turn, also meaning you can lean the bike less? I know there was a thread on here earlier (found it while I was searching for the article I read awhile back and couldn't find) http://forums.superbikeschool.com/index.php?showtopic=500 I always figured the reason riding twisted up doesn't help matters is that it often puts your head over the center line of the bike, instead of towards the inside. It seems like, if I'm on th
  9. It's about right from what I've always heard. It's always disheartening to see a guy 100 lbs more than you pass you lol
  10. (Hopefully you can get some answers on ride height and such, but once you get that...) Start with setting the sag: http://www.superbikeschool.com/multi-media/sag.php You'll need a friend or two, and I would do it while wearing your typical riding gear when you sit on the bike.
  11. One of my friends had one thing written on his bar pad on his supermoto during races (not sure why he was lookin down at it anyway, but..), and all it said was "RELAX!!"
  12. Pretty good summary; it really is a domino effect. You find one simple thing you are doing wrong, and you start backing into how to change, and realize you end up changing almost everything! Like, Ok, this session, I'm going to work on turning quicker. Done. Ooops, looks like I know have to change my entry point. That changes your speed, and your braking, and calls for further adjustment, and so on. And in the process of all that, you're likely to find something to change. I usually try and pick one thing at a time to work on during a session, but I always take at least one ses
  13. Excellent. Been gone a few days, I'll get to that and back to you later today for sure. Anyone else? Now is a good time to get me an application. Even if you aren't ready now, best to do the application, and if you are a good canditate, can let you know what steps are needed. Here is one thing: most of my full-time coaches over the last few years didn't pass the tryout initially. Best, CF As you know, I'm working on it We'll talk again when I get a chance to sign up for a school!
  14. Well, I can understand your feeling completely. I had a big crash a few years ago and I was never sure exactly what happened. As it happens, Cobie spend about two laps riding behind me, then procedded to tell me my biggest bad habit and what it could cause (and went on to describe exactly how I crashed; mystery explained!). Turns out I've been adding lean angle and throttle at the same time, and none of the other schools I've been to had happened to point that out to me. Personally, (and this may sound cliche, but it really works for me) the one thing I've learned about getting quicker i
  15. I've experienced the same feeling, and chalked it up to the same theory. New tires was the cure for me. I did my first track day on street tires (Metzler M1s) and they gave me great feedback, and I could tell by the end of the day when I was starting to push them harder and started to feel them move around more.
