EK/PBR 420SR 14/51 Chain Kit - Ultra-Light Sprocket by EK CHAIN: a set designed for urban use and small displacement motorcycles. The SR series maintains great flexibility even after prolonged use thanks to a heat treatment process applied to the plates, which increases their wear resistance without compromising the chain's flexibility.
Ideal for urban configurations and the 50 cc models mentioned in the compatibility (BETA RRT 50 ENDURO TRACK / RACING / ENDURO 2013), this kit provides a complete solution for replacing the transmission and achieving a flexible and durable chain. Before installation, please check the exact compatibility with your model and the condition of the sprockets and guides. This product is intended for riders seeking reliability and lightness in a ready-to-install chain kit.
