[QUOTE="Fred W, post: 921740, member: 3828"] I understand what you are saying about the equalizing effect that wheel slip would have on the launch, but I think you are missing something (just not sure what) or else I am. My simple mind says that (after exceeding the point of wheel slip) having the mechanical advantage of lower gearing allows the bike's engine to apply more torque to the rear wheel (and ground). This [I]has[/I] to result in quicker acceleration rates through all of the gears. All other things being equal, it shouldn't be until after the shorter geared bike exceeds maximum power in top gear that the taller one would "catch up". [/QUOTE]
