The RK MXZ4 Series transmission chain (manufacturer reference: GB420MXZ4-130CL) is designed for demanding off-road riders in Enduro and Motocross. Engineered for MX and SX riding, it combines a robust construction with components designed to withstand the stresses of trajectories, jumps, and accelerations typical of off-road riding.
This non-O-ring chain prioritises ease of maintenance and mechanical longevity thanks to its reinforced components. Its black and gold finish adds a racing touch to the sprocket and crown. Ideal for those replacing a worn chain or preparing a training bike, it easily fits on the transmissions of 125–150 cc off-road machines. For lasting performance, ensure proper alignment, recommended tension, and suitable lubrication according to riding conditions.
