I have an 02. Cosmetically, they are the exact same.
For 03, I think that they may have changed the crank weight a little bit and made a few other minor changes.
I will tell you that I absolutely love my 02, AFTER I got the forks sorted out. I have read that the 03 forks have a similar problem. The power is excellent, the bike is stable, it handles well, and the ergonomics fit me. The only thing that I would look into doing if the bike is all stock is having the forks revalved. Stock they have a really nasty midstroke harshness. The shock is good.
