PBR C45 Steel Standard Sprocket 4597 - 428 (Manufacturer Ref: 4597 42 C45)
Designed by PBR, a brand born from motorcycle competition, this standard sprocket is aimed at riders looking for a reliable maintenance part for their transmission. Its steel construction (C45 designation) and black finish make it a sleek option suitable for everyday roadsters.
This sprocket fits directly into the compatible roadster drivetrains and serves as a replacement part to maintain the original transmission geometry. It is compatible with popular models such as the HONDA CB 125 F (2024, JC74 2021) and the HONDA CBF 125 M (JC40 2014) as indicated by compatibility.
Before installation, check the chain pitch (428), the number of teeth, and compatibility with your rear wheel. For safe installation, adhere to the manufacturer's torque specifications and inspect the condition of the sprocket and chain during replacement.
