you would have to log onto redmonkey.com/7r.
they might know. It depends on the speedo and the spacer they use. No way to tell. The thread I saw the guy used a zx10r fork tubes with the zx7r triple tree. he had to make a mod to the zx10r axle to make it work. than he had to make small shims to space out the zx7r rotors.
sorry I can;t be or more help.
Only 1 way to find out. that's by buying a used rim on ebay and testing it yourself!
As you have seen in some of my posts, i was able to put on 2 vfr swingarms on my 7r's with spacers and a bit of fab'ing so anything is possible!!!!!!!!!!!!!
