Regina Chain 520 GPXV Series Chain

Regina Chain 520 GPXV Series Chain

At the highest levels of motocross, supermoto, and premier e-moto racing, every fraction of horsepower matters and mechanical failure is not an option. Developed and proven in MXGP and MX2 competition, the Regina 520 GPXV Series Chain is a non-sealed racing chain built for uncompromised performance. By eliminating internal friction-causing seals, it reduces drivetrain drag so power transfers directly to the rear wheel. Built to handle the shock loads of 450cc four-strokes and the instant torque of high-output electric machines, the GPXV is made for harsh race conditions. Regina's shaped bushings increase pin contact area to reduce localized wear and resist chain stretch. Thick alloy plates, shot peened rollers, and high-load pins add fatigue resistance through hard landings and deep whoops. Finished in factory gold, the 520 GPXV delivers lightweight efficiency, serious durability, and sharp throttle response for riders who need to stay on the gas and ahead of the pack.
