Regina Chain 420 OROY Series Chain

Regina Chain 420 OROY Series Chain

When you are wringing every last drop of power out of a small displacement dirt bike, you need a chain that can take abuse without dragging down performance. The Regina 420 OROY Series Chain is a premium non-sealed roller chain built to handle the severe demands of off-road riding and motocross racing on machines up to 85cc. By eliminating heavy internal seals, it reduces friction and improves power transfer to the rear wheel so you get more from the engine. Durability is central to the OROY Series. Regina equips it with larger diameter alloy carbon steel pins and thicker plates to increase tensile strength and fatigue resistance under aggressive throttle inputs and hard landings. Extended bushings and solid rollers help reduce wear over time so the drivetrain runs smoother longer. Finished in a gold color to match its factory-level intent, the 420 OROY is a serious upgrade for any mini motocrosser or pit bike.
