What years fit each other (2000 & up) and does “fit” mean you need to spacer the calibers. Thanks for your help
Can't answer for all years you mention, but all 5 spoke wheel radial caliper 310mm rotor R6 05 - 16 fit each other. 04-06 R1 and 06-15 FZ1 320mm rotor will fit the r6 with caliper spacers First gen 99-02 R6 3 spoke wheels 298mm rotors fit those years 03-04 R6 5 spoke wheels 298mm rotors and all R6S interchange 98-01 R1 shared the same wheel and rotors (maybe 02-03 as well, not sure) The R1 went to 310mm rotors in 07-08 but I think kept the same 5 spoke wheels as 04-06, not sure about them. Hell, they might have the same 5 spoke wheels all the way until 2015 Don't know about 17-present R6. Don't know about the 15-present R1
