My MC18 rotors measure 276mm and I have a set of CBR600 (F3) EBC pro lite race rotors, they bolt right on but measure 293mm. I did read that NC30 lower fork will allow to mount NC30 rotors, but not sure what size they are. If anyone knows the diameter I would greatly appreciate it. I can modify things to work with adapter plates etc, but prefer not to do this

I don't want to use CBR600 fork because it uses 2 inferior piston caliper, I am however shortening the CBR cartridge to be fitted in to my MC18 fork!
