Brake upgrade

[Billby]

Can/do 1993 zzr1100 front discs and calipers bolt onto a zephyr 750?

Don't believe so. Part numbers are different. Zephyr shares the front braking system with the ZG1000. The ZZR100 shares calipers with the 91-93 ZX-11.

Shouldn’t there be some way of calculating any caliper to any fork based on bolt center distance, and offset spacing? I know I’ve seen four-pot calipers fit to Zephyrs before, search the tag on Instagram and you’ll see plenty of riders in Japan with Tokico calipers on their bikes. But I haven’t been able to find instructions on how to do the calculations to make sure you’re buying the right part.
