possible rotor swap?

hi all, long time lurker, first question. what possible rotor swaps are there for larger diameter rotors on the 1981 kz750 4 cylinder bike with the Enkei mags?
thanks.

I dont think you can go much larger diameter rotor, as you will likely have to change out the caliper as well - to provide for extra clearance.

Might be best to just measure up max possible rotor size you could handle (diameter, offset, bolt count, spacing, etc.), then go to a wreckers and check out your options.

Better upgrade is to swap out calipers and lines for multipiston and steel braided.

Good luck!

The factory rotors are plenty big. Get the brakes operating properly and then go with SS lines. It should stand you on your nose.
