RK Standard Series Transmission Chain (ref. 420SB-110-CL) — M420 chain designed to replace the primary transmission of small displacement motorcycles and quads. Made from medium carbon steel alloy, each component has undergone heat treatment and shot peening to enhance wear resistance and mechanical strength. The riveting is done at four points between the axle and the rollers, ensuring a solid and consistent construction.
This RK chain is aimed at riders looking for a simple, robust, and easy-to-install transmission part. Ideal for urban use, roadsters, enduro, motocross, or quads, it fits common sprockets and crowns and can be quickly installed using the provided quick link. Remember to check the tension, lubricate regularly, and inspect the wear of the sprockets to maintain the proper functioning of the transmission.
