K5 Series 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.
