RK 428HSB-124-CL — Reinforced 428H transmission chain, designed for enduro and motocross. O-ring free chain (non-O), intended for heavy use on 125–200 cc motorcycles. Made from carbon alloy steel with heat treatment and shot peening of all components for increased mechanical strength compared to standard chains. Pre-tensioned and pre-stretched to limit initial elongation.
This chain is aimed at riders looking for a robust and economical transmission for demanding off-road conditions. Its pre-stretched design reduces the need for frequent adjustments after installation, and the included clip attachment makes it easy to install on the motorcycle. Ideal as a replacement transmission component to prepare a machine for intensive riding without resorting to O-ring chains.
