MXZ4 Series Transmission Chain by RK — manufacturer reference: GB428MXZ4-136CL
Designed with the expertise of the Factory MXGP teams, the MXZ4 chain is aimed at demanding riders looking for a robust transmission for lightweight machines. This heavy-duty non-O chain reinvents durability with special alloy pins treated with RK HCR (High Tech Chromium Carbide Layered Pins), which limit wear and help absorb shocks during jumps and demanding riding phases.
Ideal for trails and races where jumps, accelerations, and lateral stresses are frequent, the MXZ4 features a construction designed to last without resorting to an O-ring. Replace your chain set while respecting the link length and pitch of 428 to ensure a secure fit and clean transmission performance.
