Designed by PBR based on its experience in competition, this standard steel sprocket 406 is aimed at demanding riders looking for a robust and reliable final drive. Machined from high-quality 18NCD5 steel alloy, it fits on drivetrains equipped with a 520 pitch chain.
The choice of alloy and a strict manufacturing process ensure excellent resistance to corrosion and abrasion, as well as machining precision that limits play between the sprocket and chain. Ideal for cross or roadster use, this sprocket is suitable for transmissions subjected to repeated stresses while offering durability over time.
Common compatibilities (examples):
A simple and robust replacement part to replace the original sprocket, to be installed during a final drive revision or a gear ratio change.
