The PBR standard steel sprocket 2147 - 525 is designed for demanding riders seeking a reliable drive component for their roadsters or lightweight off-road machines. A product of PBR's competitive experience, this sprocket is machined from an alloy of steel 18NCD5 known for its high mechanical properties.
Designed to resist corrosion and abrasion, this PBR sprocket minimizes wear in contact with the chain and contributes to smoother transmission. The controlled manufacturing process ensures precise tooth geometry, reducing friction and promoting uniform wear of the chain and sprocket. Ideal for use on roadsters or in motocross where drive reliability is essential.
Before installation, always check the chain pitch (525) and the number of teeth to maintain the correct gearing and desired engine behavior.
