PBR Steel C45 Crown Tempered 4642 - 525 (Manufacturer's reference: 4642 38 C45T)
Designed for demanding riders, this PBR crown made from treated C45 steel is intended for 525 transmissions on roadsters and touring machines. CNC machined, its tooth area undergoes a hardening treatment and induction tempering to increase wear resistance where the chain engages. The result: a robust piece with a sleek black finish that performs mile after mile.
Ideal for replacing a worn crown and regaining a clean and even tooth profile, it offers good value for money without compromising on strength. When mounted on a properly adjusted transmission, it contributes to controlled wear of the chain and sprocket.
