PBR Steel C45 Standard Sprocket 857 - 520 (Manufacturer's reference: 857 46 C45)

This PBR sprocket, designed for chain drives with a pitch of 520, incorporates expertise derived from competition. Machined from C45 steel and finished in black, it is designed for standard mounting on the rear axles of quads, motocross bikes, and roadsters. Ideal for replacing worn parts, it maintains the tooth geometry suitable for 520 chains and the torque of the listed engines.

PBR relies on controlled production and field experience to offer robust and consistent sprockets. By replacing the sprocket with a compliant part (even chain pitch), one can achieve clean chain guidance and more uniform wear of transmission components.
