I have just send to machinist the dimensions of a 900RR wheel to fit the 600f2 swingarm.
Basically there were some few/minor parts to be changed/fabricated.
Needed fabrication/machined:
Left and right wheel spacer
Inner spacer from the Sprocket carrier
Need to be machined down
sprocket carrier
Right side of the rear wheel (where the brake disc seats)
All the work is to be done in a way that I could revert the original f2 wheel.
No problem with chain clearance.
Sizes in mm will be available as work is returned from my machinist.
By the way, I already rode a f2 with tose changes, and could not believe the difference in grip on turns. Just felt an initial more effort to turn. But as you begin everything just felt more assuring albeit a worn rear shock. Also, due to the increase in ride height the pegs stayed longer away from tarmac.
