A good way to update your 1985-'89 front end. You will need the 1993-2007 rotors (298mm) and calipers (100mm O.C. mounting bolt pattern). The '85-'89 front brake master cyl will work, as will the hoses and splitter on the lower triple tree.
Consider adding cartridge emulators from Race Tech, RICOR or YSS, and fork springs from the same. Progressive Suspension also has replacement fork springs.
