This kit includes everything needed to get a powerful, race team tested brake system designed for easy installation and extreme conditions. Designed for both trail and track, this kit is for the rider that needs more than what the stock brakes can provide. Drastic increase in lever feel, modulation and brake torque. Every high-quality, Galfer-patented rotor is made from a proprietary 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. To ensure that you are receiving only the highest quality, Galfer tests their rotors using their COSMOS analyzing system. Galfer uses a patented design that includes an inner cut which equalizes heat transfer and dissipates much faster during aggressive motorcycle riding.
