Every Galfer™ Wave® rotor is made from a mix of virgin high carbon 420 stainless steel, laser cut (never stamped), double disc-parallel ground to assure perfect parallel flatness, and heat-treated to each specific application. This longer-lasting rotor is designed for the rider that wants more than what the stock brake system can provide. Rotors are extremely predictable and consistent with a drastic increase in lever feel, modulation, and brake torque. Galfer's Superbike wave rotors are lighter than the original and feature a full floating directional design with more leading and trailing edge friction. Both rotors work well in wet or cold brake conditions and provide a consistent stopping feel and control. Seamlessly replace your stock rotor with a full instruction manual and easy installation.
