RK’s 520 MXZ5 is a race-focused drive chain developed with MXGP factory teams, built to handle hard landings and extreme shock loads. HCR-treated alloy pins improve wear resistance for consistent performance.
The RK 520 MXZ5 Drive Chain is built for riders who demand strong, precise power transfer in motocross and off-road riding. Developed with MXGP Factory Teams, it’s designed to cope with the harsh realities of racing—hard acceleration, gritty conditions and heavy shock loads from big jumps—while maintaining reliable drive and durability.
A key advantage of the MXZ5 is its special alloy pins with RK’s HCR Treatment (High Tech Chromium Carbide Layered Pins). This treatment drastically improves pin wear resistance and helps the chain absorb shock loads, making it a great choice when you want consistent performance through long motos and intense riding sessions.
