MXZ4 Series Transmission Chain by RK — manufacturer reference GB428MXZ4-134CL. Designed for demanding riders, this heavy-duty non-O chain combines a robust steel construction with a black and gold finish for a technical yet polished appearance. Developed in collaboration with the Factory MXGP teams, it is aimed at off-road demands while remaining relevant on the road.
The technical feature lies in its special alloy pins treated with RK HCR (High Tech Chromium Carbide Layered Pins), designed to enhance wear resistance and better absorb shocks related to jumps and extreme stresses. The result: a chain designed to last on abrasive terrains and to maintain smooth transmission between engine, sprocket, and crown. Ideal for users seeking a robust chain, developed for competition, to be installed according to the recommendations of your motorcycle's manufacturer.
