2003 5 spoke R6 Fronts will slot in but you will need to find discs that work or caliper spacers, discs have different amount of mounting bolts. Rears need some work as the chain side is OK but the disc side needs additional spacers and different calipers, caliper carriers and discs.
They do look better than the three spoke originals (IMHO) and have the same rim sizes so tyres stay the same.
