I was approached by John who had a late model CBR USD front end fitted ti his 1980 Kawasaki KZ750E1 caferacer. John wanted to retain his factory front wheel but use the later model CBR front end. I had to first find disc rotors that would lend themselves to fitting into the new calipers and bolting to the old wheel. I machined 2x adapters for the front hub that then adapted to the new rotors, also centering the rotors into the radial calipers. Adapters for the front axlPhotoGrid_1428051385698e were turned up on the lathe to achieve the end result.
