Manufacturer Ref: 4447 41 C45T

The PBR C45T 41-tooth sprocket is a final drive component designed for demanding riders on roadsters and touring bikes. Made from C45 steel, it is CNC machined and then subjected to targeted heat treatment: quenching followed by induction tempering in the tooth area. This process enhances the wear resistance of the part in contact with the 525 chain for improved durability over long distances, while maintaining the precision of the tooth engagement.

• Material: C45 steel (treated)
• Colour: black
• Number of teeth: 41
• Chain pitch: 525
• Machining: CNC — tooth area treated by induction
• Design: developed with MotoGP and Superbike teams

The black finish and performance-oriented manufacturing make this sprocket a relevant choice for replacing or optimizing the final drive on sports bikes and roadsters. It offers a good balance between robustness and price, suitable for road trips and sustained use.
