[QUOTE="G-S"] I ride them all the same way... close to thier limits :) The inertia needs to be overcome, that takes strength and mass.[/QUOTE] Which misses the point that inertia can be both a plus and a minus - see examples above. And if you think that you can overcome the inertia of 250Kg at 100km/hr I'd suggest you go consult IK for a physics lesson, you can only redirect it, and yes in certain circumstances redirecting that mass requires a bit of force, but most people have sufficient strength to do that provided they put the right inputs in at the right times. If being a power lifter was a big advantage the motoGP guys would be a very different shape and size to what they are. Most of (with a couple of exceptions) the sucessful bike racers over the last 50 years have been comparatively small, Rossi and Xaus are the only two reasonably successful ones I know of that would be of above average height and there's *heaps* below average. And the tall ones are bean poles, they aren't built like Arnie. JL (stop creating interesting arguments you bastids, I've got an assignment I should be doing)
