EK/PBR 420SR 14/47 Chain Kit - Standard Sprocket by EK CHAIN: a complete kit designed for the transmission of small urban motorcycles. The SR series features a specific heat treatment on the plates to maintain flexibility and strength even after repeated use — ideal for city commuting and frequent stop-and-go situations.
This kit is aimed at riders looking for a simple and robust solution to refresh the transmission of their 50cc or light scooter. The 14/47 setup offers a good compromise between starting and torque in urban areas. Be sure to properly adjust the tension and maintain the chain (regular cleaning and lubrication) to optimize the wear of the components.
Notable Compatibilities: RIEJU RS2 50 MATRIX PRO (2003 - 50cc), RIEJU RS1 50 (2003 - 50cc).
