The PBR crown reference 281 36 C45 is a transmission part designed for roadsters and 125cc motorcycles equipped with a 520 chain. Machined from C45 steel, it offers a robust construction intended to withstand torque stresses and daily road use. PBR applies its competition expertise to this standard crown, designed for simple and reliable installation on your chain.
This crown is ideal for replacing the worn element of your transmission and restoring a gear ratio consistent with the 520 chain. Its black finish allows for discreet integration on most rear transmissions. Installation and adjustment remain those of a standard crown: cleaning, checking the wear of the sprocket and chain, and then tightening to the torque recommended by the manufacturer.
Common compatibilities: HONDA NSR 125 R (JC22 and JC20) and HONDA CRM 125 R. Always check the precise compatibility with your model and year before installation.
