EK/PBR 420SR Chain Kit 14/50 - Standard Sprocket
Designed for urban use and small displacement motorcycles, this EK CHAIN 420SR chain kit combines a 14-tooth sprocket and a 50-tooth sprocket for a transmission suited for 50cc engines. The SR series is distinguished by targeted heat treatment of the plates, which maintains the chain's flexibility even after long hours of use while increasing wear resistance.
This kit is aimed at riders looking for a robust and flexible chain for city riding or daily commutes. It is compatible with 50cc models such as BETA RRT / RR Motard (see compatibility list). To preserve the lifespan of the drivetrain: check the tension, clean and lubricate the chain regularly, and replace the sprocket and chain as a pair if necessary.
