I am riding bikes that could vote. My newest is a 2004. If I was racing and trying to be serious about it I would be looking for something newer.Theres a couple other factors in clutch life, rider ability, aggression, type of terrain, oil used, etc. etc.
Can't say I've ever worn a basket out so bad I had to replace it, I just put a clutch in the WR, filed the basket down and away we went and that ones 13 years old.
13 years old... I might want to think about a new bike....
