rear brake rotors?

[honda182]

Are 250R rotors the same size as the 450r in the rear? if not which one is bigger. Also will the 450 brake rotors bolt right up to a 250R antifade setup?

yeah I think they are the same size o.d. but the rotor bolt pattern is different. 450r uses 3 bolts while the 250r rotor uses 4. There is also a slight difference in depth so that the hub sits deeper in the carrier.

So the rotors are the same size but they have a different bolt pattern
