The reason I would stay away from an 03, its kind of a 1 shot wonder, 99-02 are pretty much the same, 04-07 pretty much the same. If you were to get the whole bike the 03 would be fine, but if your going to try to get the parts don't use the 03 as there aren't as many, primarily swingarm and linkage are the biggest difference. I've pieced them togather from parts off Ebay and rarely do find 03 parts. I had an 03, it was a great bike, just all alone in design.
