I just picked up an '83 CR480R with front and rear disk brakes. Front end is from an '89 KX250 (works great) and the rear is a hodgepodge of a modified stock swingarm, KTM brake caliper, and LC4 rear wheel. It's functional but kind of messy. Has anyone done a rear disk brake conversion on a CR480R or similar? I wonder if something like a stock LC4 (right-side chain) swingarm will fit.
On that note, has anyone put modern forks on an old bike like this?
(and yes, I know the rear axle nut is AWOL
