The clutch hub is two pieces and was improved a little in 03 but still sucks. If you plan to race or do any hard launches I would highly recommend it.

If you do a lot of wheelies, it can give you a hickup in powering it up!
Feals like something is backing OFF when you're on the Power!
Or if you spin the tire at low speeds it can give you a bucking feeling when it fights for traction on and off with traction/power being applied!
The main reason is to keep from damaging something.
