RK Standard Series Transmission Chain – Manufacturer Ref: GS420SB-140-CL
Designed by RK for off-road use, this Standard Series transmission chain is intended for small displacement Enduro and Cross machines. Made from medium carbon alloy steel, it is pre-tensioned and pre-stretched in the factory to ensure even load distribution and limit initial maintenance. The components have undergone heat treatment and shot peening to enhance wear resistance.
With its two-point axle riveting and solid rollers, this RK chain offers a robust solution for riders seeking reliable transmission on trails or tracks. Maintain it regularly (lubrication and tension) to preserve its longevity and performance in Enduro/Cross use.
