Manufacturer's ref: GB428MXZ1-122CL — RK MXZ1 Series Transmission Chain
Designed for roadster, enduro, and motocross practices, the RK 428 MXZ1 is a heavy-duty non-O transmission chain that focuses on simplicity and robustness. Made from chromoly steel, it features seamless rollers and bushings for mechanical performance suited to off-road demands and intensive use on trails and lightweight motorcycles (up to 150 cc off-road).
In the absence of o-rings, the MXZ1 requires regular maintenance: cleaning, lubrication, and play checking to ensure longevity and smoothness of the transmission. Ideal for riders seeking a reinforced chain for demanding terrains, it is compatible with suitable sprockets and crowns and should be installed according to manufacturer recommendations.
