EK/PBR 420SR 14/48 chain kit - standard sprocket: a drive system designed for urban trips and small displacements. The SR series from EK CHAIN combines heat-treated plates and a design that maintains the flexibility of the chain even after prolonged use. The result: a robust and smooth transmission, suitable for the stop & go demands of city riding.
This kit includes a 14-tooth front sprocket and a standard 48-tooth sprocket, mounted on a 420 pitch chain. Ideal for scooters and 50cc models like Rieju, it offers easy installation and linear behavior during acceleration.
Compatible with urban models such as the RIEJU SPIKE 50 (2003/2004) and the RIEJU RR 50 (2004). To ensure longevity and safety, follow maintenance recommendations: correct tension, regular lubrication, and checking for tooth wear. A reliable kit to keep your two-wheeler's transmission ready for daily use.
