updated picture of 1985 honda cr 250 rear disc brake converstion. 1985 honda cr 250 with 1987 honda cr 250 swingarm. 1996 honda xr 400 pivot plate. 1987 honda cr 250 brake system. the swingarm is an exact fit but i had to use 1985 lower link so that shock would bolt up. the pivot plate will have to be modified. this is just a mock up of where to place everything once i get the measurements right i will weld brackets for brake pedal and master cylinder. everything so far looks good. also waiting on rear rim from 1991 honda cr 250.
