Regina Chain 420 RX3 Series Chain

Regina Chain 420 RX3 Series Chain

When you are shaving tenths off lap times on a youth racer or high-performance mini, drivetrain drag and chain stretch can cost podium finishes. The Regina 420 RX3 Series Chain is a professional-grade non-sealed racing chain built for motocross, supermoto and off-road machines up to 85cc as well as high-output electric pit bikes. By eliminating friction-inducing internal seals, it helps send maximum horsepower to the ground with minimal parasitic loss. Built to handle hard gate drops, deep whoops and heavy roost, the 420 RX3 uses race-proven engineering throughout. It features Regina's specialized "X" chromized alloy carbon steel pins with exceptional surface hardness to slow pin wear and reduce chain elongation. Extended shaped bushings and shot-peened solid rollers help distribute impact loads evenly, while beveled inner plates promote positive sprocket engagement in tacky mud or deep sand. Finished in factory gold, the 420 RX3 delivers the premium strength, low drag and dependable durability needed to grab the holeshot and stay out front.
