PBR Standard C45 Steel 843 - 428 SprocketRef : PBR00381A / 1075459004

The PBR steel C45 sprocket (ref. 843 54 C45) is designed for demanding riders seeking a reliable transmission part for their motocross or roadster machine. Engineered to replace the original sprocket, it features a standard tooth count of 54 teeth and a chain pitch of 428, all in a sleek and robust black finish.

• Material: C45 steel, suitable for the stresses of final transmission.
• Number of teeth: 54 teeth — compatible with 428 chains.
• Type: standard, direct replacement for the original sprocket.
• Finish: black, discreet look and protection against wear in varied conditions.

Born from PBR's expertise in competition, this sprocket is designed to maintain a clean and precise transmission between the pinion and chain, whether for off-road or on-road use. It is particularly suitable for smaller displacements listed in the compatibility, such as certain TT-R 125 models. Before installation, check the chain slack and the condition of the pinion to ensure even wear and extend the lifespan of the entire assembly.
