    Turn-in point techniques

    There are several reasons why you would want to apply throttle before the apex, but the very important point before considering any of this is that adding lean angle while accelerating put a lot of stress on the tire. In this situation the tire can react unpredictably, losing and regaining grip uncontrollably and shaking the rider out of the bike. At any rate, when giving gas in a turn we transfer the bike weight to the rear making the front easier to handle. In a chicane, peaking up the throttle in the middle of the turns helps with the fast direction changes (but definitely not while giving the first strong lean input). Also when riding on bumps ideally you want to open the throttle, for the same weight transfer reasons. Another reason is engaging traction sooner. Racers tend to give some gas before the apex to start engaging traction and power up immediately after the apex. This is a lot more obvious in flat track or dirt riding when riding through the turns with a smaller displacement bike. Finally in very long turns we have no choice unless we want to park the bike somewhere in the middle of the turn. I prefer the expression "picking up the throttle" to "maintenance throttle", because it the former gives better the idea of a minimal input.

    Steer for the Rear - Ch13 of TOTWII

    You slide the rear going into the turn (or going into the lean). Visually it almost looks like a slow motion sequence of the rider applying leaning forces on the bike. Once the bike is committed to the turn a rear slide can only cause stability problems. On the exit it can cause a high side.
  3. I'm having a hard time to improve my weak side corners, left in my case. My speed is lower and the lean angle is around 5 degrees less than the right corners. Are there exercises designed to train the weaker side?
  4. I will be at Barber 5/28-29. Would like to meet anyone from the forums, let me know if you're also registered for those dates. Alberto

    Maverick's riding style disected

    Yes exactly. Motorcycle racing is not a sprint sport. It requires constant focus over a full 40 minutes race. In facts you want to avoid excessive fatigue, a lot of work goes into that.

    Sounds like a lot. I'm skeptical.

    Lowering the body

    In practice I feel that a higher body position causes more side movements and stress on the rear tires. The air turbulence on the upper body increases the problem. Can you imaging riding a 90mph corner with that body position? Also I'm not clear about the physics in the illustrations: in the last example I understand the center of gravity has more leverage because it's taller, but it's also farther away from the center of the tire and the bike axe. Isn't that another source of leverage that works against the bike stability?

    Wished-for bike?

    I haven't played with enough bikes on the track to tell, but I definitely would like to have more racing bike options available. Buying a racing bike is such a headache: either you purchase a stock bike and all the mods, then dispose the stock parts, or buy a used racing bike, which is never what you exactly want since there are only few options available in the local market (if any). Sometimes I wonder if there isn't a market for fully built racing bikes.

    Lowering the body

    So I was looking at this picture and wondering how it possible to lower your upper body as much throughout a race or even just a trackdays session: Lowering my body more consistently is one of the areas I need to improve. I had some better results using the tank for chest support but I can't imagine keeping that position on every corner for a full race. I don't think it's just a core muscles problem?

    After-market throttle cables

    Rob, did you try the rev2? There are multiple options, if you don't want to use the progressive wheel you can mount the linear one. For the cost it's one of my favorite upgrades. It changed my riding experience greatly.

    After-market throttle cables

    This is the product: https://www.motionpro.com/featured/rev2_throttle Street/Road Race Kit (RR Cam) Sportbike oriented cam profile reel for the Rev2™ Throttle Profile acts like a slow throttle to 40% opening, them progressively changes to fast profile from 70% to 100% throttle Allows rider greater control at lower throttle openings, but acts like racing throttle at higher throttle openings Good for all levels of riders, experts will appreciate the greater control at the limit, less experienced riders will like the smooth on/off throttle feeling
  12. I'm wondering why there is only one major producer of after-market throttle cables. Their flagship product is a progressive cable that runs exponentially faster as you open the throttle: at lower speed the sensitivity is almost the same than the stock cable but as you open gas the cable will run faster towards its end. In general, throttle control is more critical at lower speeds (there could be tracks with very fast corners that require the same level of throttle control than slower corners, but I am not aware of any. Please let me know). Ride-by-wire changed a bit the need for this type of upgrade but did not remove the problem (long discussion). But this product doesn't do just that. It also has a smoother, more stable run (hard to describe with words) and removes that dead "play" at the begin of stock cables (I know it can be reduced but not removed). With all the stress on traction control why there would be only one fine offer? I give this upgrade more points than rear-sets and master cylinders, yet everybody jumps on rearset and brakes upgrades but not on a precision throttle cable?

    The fast riders and the fastest riders

    Another thing about club racing is that most races are sprint, about 6/7 laps or a quarter of a regular WSBK or motogp race. Tire preservation is not as critical.

    The fast riders and the fastest riders

    So to illustrate this is one of the videos I had in mind (I can find others). I won't comment, please tell me what you think about exit corners throttle management:
  15. One of the differences I noticed watching many onboard racing videos is that a majority of expert club racers tend to be aggressive on the throttle right after the apex. They seem to be waiting for that magic point in the corner where they can optimize the bike power. WSBK/motogp videos on the other hand look more symmetrical in throttle control around the apex. Deceleration and acceleration change of speed are similar. Is this a valid observation? At first I thought this happens because the fastest riders have higher corner speed. But could it be because of the more sophisticated electronics managing the bike?
