Dan- it should fit, but the m/c may be different. Just to be sure, go to the Yamaha web page and compare the part numbers in their parts fiche. I'm guessing your problem is in your m/c if you crashed the bike on that side. I would rebuild the m/c before going to the trouble of trying a whole different brake system on it.

Did some diggin', and the part numbers are different. However, the 03 250F matches the 03 450F. Regardless, the 01 stuff should still fit on your bike.
