KZ750 rear master on a '04 GSX-R rear brake.

In the process of swapping an '04 GSXR rear swing arm on the bike, and it's time to think about the brake. Anyone for see a problem using the KZ master to drive the rear brake? Any reason I should swap to a GSXR master?

is it wider?

As a whole, yes it has a 180 rear wheel. The rotors themselves have a comparable amount of surface area where the brake pads touch, if anything the GSXR has a little less.

You need to find out the M/C bore of the Gsxr unit and compare it to your stock one. If they are the same, no biggie. If they're different, then your rear brake feel will be different...and not guaranteed in a positive way.

Thanks Doug ill check into that.

I don't see why anyone would put a stretched swingarm on one of these, as though there wasn't already an issue with the tire spinning.
