Standard Series Transmission Chain RK (Manufacturer Ref: 420SB-124-CL) — a robust chain designed for enduro and motocross practices. Designed for small displacements (up to 125 cc, frequently compatible with 90 cc), this 124-link chain is aimed at riders looking for a reliable wear part for the secondary transmission.
Suitable for off-road conditions, this RK chain features a classic construction: plates, axles, and rollers treated to limit wear and maintain transmission reliability. The quick-release attachment facilitates installation and field interventions. Before installation, check the pitch, the number of links, and the condition of the sprocket/crown; regular adjustment and lubrication will extend the lifespan of the assembly.
