Driven BMW S1000RR 13-18 520 Aluminum Rear Sprocket HP Forged Wheels

Most aluminum rear sprockets start out as blank discs punched out of sheets of heat-treated 7075-T6 aluminum. The quality of these aluminum sheets vary among manufacturers and countries. DRIVEN uses only the finest aluminum available in the world. They shape the tooth profile on a hobbing machine, which guarantees the perfect shape and fit for the least amount of friction and subsequent wear when mated to the chain. The final color anodizing further increases strength and durability as well as adding a personalized characteristic. Throughout the entire process the disc undergoes rigorous quality control insuring each individual sprocket is perfectly flat and concentric. This guarantees the consumer the finest product available. Their front sprockets are made of case hardened, C45 chromoly steel, zinc plated for strength and durability and drilled for mass and weight reduction.
