MXZ Series Transmission Chain by RK — manufacturer reference: GB420MXZ4-120. Designed for enduro and motocross, this heavy-duty non-O (without O-ring) chain is intended for riders seeking a robust transmission for demanding terrain.
The chromoly steel construction, combined with seamless rollers and bushings, provides a compact structure that is resistant to the shocks of jumps and off-road stresses. The chrome-plated pins increase longevity against wear and help absorb impacts better. The exclusive RK Heat Induction Transfer (HIT) heat treatment enhances the mechanical strength of the components.
Ideal for off-road riders who want a chain ready to withstand mud, sand, and repeated jumps. Be sure to check the pitch and compatibility with your sprocket and rear wheel before installation.
