The PBR standard steel sprocket 2289 - 428 is aimed at motorcyclists looking for a robust transmission part that embodies a competitive spirit. Designed by PBR, a specialist in drivetrains, this 14-tooth sprocket uses an 18NCD5 steel alloy and a rigorous manufacturing process to provide precise tooth engagement and controlled wear.
Suitable for roadsters and small displacement bikes, this sprocket easily integrates into transmission systems for standard replacement or refurbishment after wear. Its machined teeth minimize chain snags and contribute to smoother torque delivery, useful in urban riding as well as on winding roads. Installation and adjustment remain in accordance with the vehicle manufacturer's recommendations.
