It depends on the ATV, mine uses the same platform as the 450, but if you look at the Can Am Max XT line they are longer.

I've never played around with clutch springs.... but I'm presuming --- Lighter spring = Full Compression at a lower RPM so faster earlier... Heavier Spring = Higher RPM required for full compression... so at lower RPMs clutch still not at full speed/ratio and therefore more controllable. Is this correct?
Time for an OOD ATV Meet and Greet :-)
Any place central to meet and have fun? And some friendly competition?
