EK 420SR 420 Drive Chain — Manufacturer's ref: 420SR-STL 132 SPJ
Designed by EK CHAIN, the SR series combines strength and flexibility for the final drive of small displacement bikes and off-road machines. The plates undergo a specific heat treatment aimed at enhancing durability while maintaining the chain's flexibility after prolonged use. Ideal for urban environments, quads, motocross, and roadsters.
This 420SR chain is aimed at riders looking for a reliable drive component to replace or maintain their primary chain. It is suitable for transmissions equipped with a 420 pitch and is commonly fitted on small displacement bikes (e.g., 50 cc) and trail/cross machines that require a compact and durable chain.
Rider tips: check the alignment of the sprocket/crown, adjust the tension according to the manufacturer's recommendations, and regularly lubricate the chain to extend its lifespan. Replace the chain and the crown simultaneously if wear is advanced for a clean and secure transmission.
