Regina Chain 520 GPXV Series Chain

Regina Chain 520 GPXV Series Chain

When you are competing at the highest tiers of motocross, supermoto or premier e-moto racing, every fraction of horsepower counts and mechanical failure is not an option. Developed and proven at the world championship level in MXGP and MX2, the Regina 520 GPXV Series Chain is an elite non-sealed racing chain engineered for pure, uncompromised performance. By ditching internal friction-causing seals, this chain eliminates parasitic drivetrain drag to ensure your engine's power transfers instantly and completely to the rear wheel.

Built to withstand the violent shock loads of 450cc four-strokes off the gate and the instantaneous torque spikes of high-output electric machines, the GPXV is constructed to survive brutal race conditions. It features Regina's specially engineered shaped bushings that maximize pin contact area, dramatically reducing localized wear and fighting off chain stretch. Thickened alloy plates, shot-peened rollers and high-load pins provide immense fatigue resistance over hard landings and deep whoop sections. Finished in a brilliant factory gold, the 520 GPXV delivers the lightweight efficiency, unyielding durability and razor-sharp throttle response needed to stay on the gas and out front.
