Hello everyone!

I am customising a Honda CB400F '76 and have chosen to do a modern'ish brake upgrade, mainly driven by the fact a replacement caplier for this bike is horrendously expensive, plus it will look cooler.

I have bought some calipers off a 95-98 CBR F3 and looking to match them up with a pair of rotors.

I am trying to use the stock hubs off the CB400F and machine them a little to accept the rotors so that any future new rotors are bolt on rather than needing machining themselves.

I need help getting a few specs on the Honda rotors, can anyone help or point me in the direction of a good resource?

Looking for:

1. Hub hole diameter
2. Centre to centre hub bolt spacing (opposite sides as I assume all rotors on the CBR's are 6 hole?)
3. Disc offset

Cheers in advance.

 

Just measured the stock CB400F hub in case this helps:

Centre hole diameter: 56mm
4 hole pattern (centre to centre): 76mm
Offset: 20mm
