GMA Rotors

Through extensive testing under racing conditions and in the most rugged terrain, GMA has developed the world’s finest ductile iron brake rotors for use on HD motorcycles. The GMA rotors make a significant improvement in braking power. The properties of ductile iron offer a vastly improved friction surface, better heat dissipation and dampening. When used with GMA calipers, you will achieve a true high performance brake system.
