I have heard that some of the YFZ's have had some probs with braking down, has anyone ever had any trouble with theirs taht wasnt from a wreck or anything. My good friend has one and i think its just a bunch of BS but i figured i would ask around.

 

The seal behind my sprocket broke, other than that, no problems.

 

They have had their fair share of problems, the 05 models seem to be the most reliable. 06's are having some issues.
