I machined some CBR rotors a number of years ago (F4, earlier CBR600RR, and CBR100RR) that I re-discovered in cleaning and would like to move them along. Losing money on them at this price but at this point I just want to get them people that can use them and also get them out of the garage instead of them just taking up shelf space! I'm not up on recent Honda rear rotors so if you ask it they will fit XXXX Honda CBR, I probably won't know. Take a look at the picture, send me questions with dimensions that I can check, whatever you need to feel comfortable with buying. Or, if you're risk averse with your $35, probably best to not buy as I don't want to take them back!
