Bremzen Superbike Wave Rotors are not only Lighter than original but they are also self cleaning and cooling as the rotors spin. These Rotors have more initial bite, leading and trailing edges due to the opposing slots on each side of the blade. This allows for a 20 percent increase in braking power. The floating rotor design allows for better contact with the brake pads. Rotor in picture may not be the exact rotor for your particular bike. BREMZEN ROTORS ARE SOLD IN PAIRS WHEN APPLICABLE.
