The K5 sintered compound is optimal for off-road motorcycles and ATVs. It is recommended for riders who demand great off-road stopping power and brake pad durability when riding on tough off-road terrains. The K5 series is designed for low abrasive interaction with the rotor long life and self-cleaning capabilities necessary in off-road riding conditions. Friction materials contain metal-ceramic with a sophisticated bronze-graphite and full-metal mixture formulation with fine friction particles to achieve optimal friction properties. Features: High static friction coefficient. Good abrasive resistance. Self-cleaning capability. Low abrasive interaction with the brake rotor material. Up to 3 times longer operational life compared to organic and Kevlar composite materials. Application: Dev eloped specifically for off-road motorcycles and ATVs. Can be used on both front and rear brakes. Could be used on the rear brake of road racing motorcycles.
