The '95-'97 are the same with minor changes (fork and frame reinforcement). The '98-'99 are pretty much the same and have the single headlight like the '95-'97. The engine is completely different than the '95-'97 engine and it is a little faster. Just about nothing is interchangeable between the '95-'97 and the '98-'99. The '00-'02 have the twin headlight. There is not a lot of difference in performance in any of them. The latter models are 20-30 lbs lighter than the '95-'97. I would get a '98 if the prices were similar.
