ok my friend needs a rim for his RR and i need to know if any other year will fit his bike. please give me some info cuz im tryin to do him a favor. thanks

Which RR?? the 600 or 1000?? the 600 is 03-present and the 1000 is 04-05. Almost any wheel is possible with the right machine work ( spacers, alignment, ect) After market wheels are just set up for the bike
