PBR draws on its competition experience to offer parts designed for demanding motorcyclists. The C45 steel sprocket reference 284 40 C45 is aimed at roadsters looking for a simple, robust final drive component suitable for 530 chains.
Manufactured from machined C45 steel, this standard 40-tooth sprocket features a tooth profile that conforms to the 530 pitch and is designed for direct replacement mounting. Its black finish enhances aesthetic integration with the chain/sprocket assemblies of classic and custom motorcycles.
Compatible with several classic roadsters — including the HONDA CB 750 CUSTOM (RC06) 1982, CB 650 SC (RC08) 1982, and CB 650 (RC03) 1980 — this sprocket can be directly replaced when the pitch and number of teeth match. Before installation, check the chain/sprocket alignment and the condition of the engine sprocket to ensure even wear and smooth torque transmission.
