You run into lots of challenges doing this. Particularly, modern calipers have pistons on both sides of the rotor: the wheel spokes are fairly close to the stock "floating" single piston caliper and you don't have enough clearance for double sided calipers.
As I recall, all the bike's I've seen with updated brakes (floating disks and multipiston calipers) use the entire front end of a donor bike, or at least the wheel/disk assembly. Cast or comstar type wheels are pretty much required, the original wheel's spokes are too wide at the caliper location.

do ti all the time on rd's w/spoke rims, FZR rotors and ducati monster rotors bolt on. my H1 has an R1 rotor on it, etc albeit that has a mag on it.
with the larger rotor, then the spoke clearance isnt an issue as much. i have a few 6 piston tokicos and and some FZR calipers + other ones. I can make any fit, just trying to avoid making an adapter for the rotor. do any of the CBR rotors share the rotor bolt pattern?
