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.
