The mounting bolt spacing is the same at 63mm. I don’t believe that anyone manufactures the spacers required, but I think the dims needed can be found on here somewhere if you have someone to machine them.

The spacers used to be for sale on uk ebay. Not sure if they still are

I have in the past fitted these callipers to a zxr400,
Using 10mm bolts with a reduced thread 8mm.

 

and did you notice difference, you get better stopping power with standard disc?

 

After the upgrade, 6 pots & Galfer lines, I warped my OEMS that summer, 35k OEM miles, maybe 1500 miles into the upgrade, & this included LoLo Pass @ very high speed. I then bought some Chinese shit & warped them halfway thru the following Summer. Thats when I lucked out & found used Braking Rotors on FleaBay, 1 red pubic hair from being totally out of racing spec, but the damn things are still there doing their shit, after 5 years of me trying to warp 'em. Imma failure!! I guess Im not that crazy.... The previous wear was done in 2 full seasons on the circuit!!! WTF!! Who r these Guys who hit 64°?

 

Fantastic braking,but I also used stealth aftermarket discs.
Also remember this was actually 600 Yamaha with zxr400 forks.

 

When I did mine I went the other route of forgoing the spacer shit, & just drilled & tapped out the calipers to accommodate the larger bolt. I also noticed with stock calipers, BRAKING racing rotors, & Galfer stainless steel brake lines, I felt little degradation from OEM 4 pot vs Tokico 6 for daily riding... however, with that being said, Im convinced the 6 pots definitely add that lil edge/feel one needs when deep into a decreasing radius, off camber corner @ 46° Buy sticky tyres though, & with a ZZR-1200 nitro gas front end thats when heaven truly begins,
