PBR steel sprocket 18NCD5, designed for 520 transmissions. Born from PBR's competition experience, this standard sprocket provides the necessary robustness for off-road cross practices where the chain and teeth are subjected to significant stresses.
The composition in 18NCD5 gives the sprocket good resistance to abrasion and corrosion, while the manufacturing process applied by PBR aims to minimize dimensional variations for a precise fit with the pinion and chain. Suitable for cross uses, it easily installs on standard 520 transmissions and is compatible with the models listed by the manufacturer.
Notable compatibility: HONDA CR 125 R (JE01) — years 1980 to 1982. However, please check the compatibility with your model before installation (number of teeth, chain pitch, and bolt spacing). This product is intended for riders looking for a durable sprocket that meets original specifications.
