I think they changed the piston in '03 when they changed the exhaust porting to accomidate the smaller web.
BTW - I did a little checking, and I do believe the pipe is different also.
I do think however thet you can use any part from a newer model on an older model. :cool:
My 02 and 06 share the same adjustability on both the fork and shock (rebound only). Paint color does not constitute a change (so it is NOT a "major point), if it does, then so the the annual graphic re-designs. The pipe may not have been mentioned in this thread, but it was mentioned in another very recent one.
I was recently in a discussion with another 65 dad, and remembered that the current bars are wider than the early ones. I can't remember which year it happened.
I guess my point is I am cleaning out my garage and I have some 2001 KX 65 stuff laying around - FMF fatty exhaust
w/muffler for example - trying to make exhaust more sellable on **** -
So that 2001 kx 65 exhaust will only fit 2000 thru 2002?
