I am trying real hard to find "all" the negatives about the 00 as compared to the 02.
Internally, suspension is pretty much the same (some changes to shock valving...forks almost identical), 00 engine is better stock and probably modded as well. Triple clamps, tanks, seat, suspension, linkage, swingarm (with some spacers, most other parts - even plastic (with a bit of mount movement) is all interchangeable if not identical. So the geometry change isn't dramatic.
Yeah, the frame looks a bit better, but I am not seeing a "generation" of improvement.
