Topic: 276mm Rotor On CB750 hub

[PPG9944]

Does anyone know what brake rotors that have a diameter of around 275 or 276mm with the same bolt pattern as the stock front hub on a cb750?  I believe i measured the bolt pattern to be about 80mm.

A 550 275mm rotor will bolt directly onto a 750 K hub. Later 750 F's are a different animal.

Ducati and Yamaha rotors fit..  Different center hole size..

754, do you have an EBC part number? I've checked a few sources and can't find one.

I don't but far as I know they made them for some of the fours. My buddy has the catalog but won't see him till next week.

I actually ran into a gentleman that does brake rotors.  Turns out stock cb550 rotors are about the diameter im going to need.  He drills and narrows the rotors to about a 5mm thickness which is also what I need.  May go that route

I think the EBC rotor only fits 77-78K and all Fs. OCICBW
