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.
- Manufacturer reference: 290 51 F
- Type: Standard
- Material: Steel (18NCD5 alloy)
- Color: Black
- Number of teeth: 51
- Chain pitch: 520
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.
