Replace your sprocket with a robust and reliable part with the PBR standard steel sprocket 4402 - 420. Designed by PBR from competitive experience, it is aimed at urban riders as well as motocross enthusiasts and roadster fans looking for a simple and effective transmission component.

The 18NCD5 material offers good resistance to corrosion and abrasion, while the PBR manufacturing process limits dimensional variations for precise fitting. The result: a sprocket ready to withstand daily wear, reduce friction at the chain/sprocket contact, and facilitate transmission maintenance.

An ideal replacement part for many 50cc models, it is particularly compatible with models such as the RIEJU MRT 50 SM (2025), the GILERA RCR 50 (2020), and the DERBI SENDA 50 R DRD X-TREM (2019). Easy installation, adaptation to urban and light off-road use — a technical and pragmatic choice to keep your trajectories clean and your chain well-guided.
