The lighter rotor assembly weighs 16.5#. The HD road race rotor assemblies are approximately 20.2# each. This puts our lighter rotor assembly at 8.7# weight savings over the one pc GT 500 rotor which equates to a total weight savings of 17.4# for the pair.
Bruce, does this use a different rotor than the GT500 design? On the FTBR page the GT500 2 piece rotors are advertised as 19.8 lbs for the street version and 23.8 lbs for the HD version. Whats the difference between the 14" rotors?
