  1. 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.
  2. Sounds like a lot. I'm skeptical.
  3. 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?
  4. 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.
  5. 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?
  6. 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.
  7. This is the product: 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
  8. 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?
  9. 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.
  10. 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:
  11. 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?
  12. Push looks interesting. There is a similar product called SpeedAngle. All these systems were released in the last 2 years, maybe a sign that the track days business is growing. Data download and displaying is fast and can be done in the garage after each session, but video synchronization from an action camera still takes a long time (I know AIM has a proprietary integrated camera solution that might be faster to use but it's more expensive).
  13. I use Racerender with AIM SoloDL data and gopro cameras. You can start with a simpler cell phone data logger like trackaddict if you don't need 10Hz GPS sampling and gear/RPMs data.
  14. Sometimes I wonder whether it's better to enter corners at higher speed than lower. For novice riders lower speed is the obvious choice but for advanced riders and racers low entry speed can hide this type of trap. High speed on the other hand can be corrected by trail braking with less risk. Not obvious to fix habit and instinct in this case.
  15. Was the reason for selling too many crashes/too much liability, or just not enough customer interest? I'm thinking extreme bike handling could help a lot in roadracing.
