Regina Chain 420 RX3 Series Chain

Regina Chain 420 RX3 Series Chain

When you are shaving tenths off your lap times on a youth racer or high-performance mini, drivetrain drag and chain stretch can rob you of podium finishes. The Regina 420 RX3 Series Chain is a professional-grade non-sealed racing chain engineered specifically for motocross, supermoto and off-road machines up to 85cc as well as high-output electric pit bikes. By omitting internal friction-inducing seals, this chain guarantees that every last bit of horsepower makes its way straight to the dirt without parasitic loss.

Designed to survive the abusive shocks of aggressive gate drops, deep whoops and heavy roost, the 420 RX3 is packed with race-proven engineering. It features Regina's specialized "X" chromized alloy carbon steel pins that boast exceptional surface hardness to drastically slow pin wear and combat chain elongation. Extended shaped bushings and shot-peened solid rollers distribute impact loads evenly, while beveled inner plates ensure positive sprocket engagement even in tacky mud or thick sand. Finished in a brilliant factory gold, the 420 RX3 delivers the premium strength, minimal drag and reliable durability needed to grab the holeshot and stay out front.
