Galfers solid-mount Rear Wave rotor provides all the advantages of the front rotor when coupled with the floating rear calipers found on most motorcycles. Combining the best materials and manufacturing process, this rotor will handle everything you throw at it. Patented inner and outer Wave design minimizes heat transfer, equalizes dissipation and evens out pad wear. Designed both for street and track. Built out of 420 high-carbon stainless steel which maintains shape during intense heat cycles. Galfer ensures that every Wave brake rotor is produced perfectly flat. Keeps brake system cooler by allowing air to pass over every point of a brake pad surface. Best friction surface of any stainless steel rotor. Extremely predictable and consistent. Provides outstanding performance even in the most aggressive conditions. Provides stopping power and performance that is far superior to any O.E.M. brake rotor. Wave design creates a better contact surface with the pads to improve braking. The shape also eliminates excessive material which translates to weight loss. Seamlessly replaces stock rotor.
