The RK 520H Heavy Duty Drive Chain is designed for riders who want a reliable, budget-friendly drivetrain upgrade without sacrificing strength. Its heavy-duty construction delivers improved durability compared to standard chains, making it a solid choice for regular motocross and off-road use where chains take constant abuse from dirt, impacts and high loads.
Because it’s a non-sealed chain, it remains an economical option while still benefiting from premium manufacturing processes that help it last longer and run stronger. The carbon alloy steel construction is heat-treated and shot-peened to increase strength and resist fatigue, while the cold-forged seamless bush supports longer chain life under demanding conditions.
