REGINA 520 RH2 is a non-sealed off-road drive chain engineered to handle the heavy loads and impacts of motocross and enduro riding. Strong pins, thicker plates and durable rollers help deliver reliable power transfer and long service life.
REGINA 520 RH2 Drive Chain is developed to withstand the severe stresses of off-road riding, where hard acceleration, roost, mud and impacts quickly wear out standard chains. Built with upgraded materials and construction, it helps keep power delivery consistent and reduces the chances of premature stretching or fatigue—so you can focus on riding instead of constant drivetrain adjustments.
Thanks to its larger diameter alloy carbon steel pins and thicker plates, the RH2 offers increased tensile strength and fatigue resistance. Extended bushings and solid rollers further improve durability, making it a dependable choice for motocross and enduro use up to 450 cc.
