Regina Chain 428 RX3 Series Chain

Regina Chain 428 RX3 Series Chain

When you are pinning the throttle in deep ruts, heavy sand or tacky mud, you need a drivetrain that delivers instant power without stretching out before the final moto. The Regina 428 RX3 Series Chain is an elite non-sealed off-road competition chain engineered specifically for motocross, supermoto and high-performance e-moto applications up to 125cc. Designed to shed parasitic friction, it eliminates internal O-rings to deliver raw, unhindered power directly from the countershaft to the rear sprocket.

Built to endure the abusive shocks of high-flying jumps and sudden torque spikes, the 428 RX3 features oversized alloy carbon steel pins treated with an advanced chromized coating to dramatically reduce pin wear and elongation. Specially shaped curl-formed bushings and shot-peened solid rollers provide rock-solid fatigue resistance under grueling conditions. Regina also beveled the inner link plates to guarantee smooth, positive sprocket engagement even when packed with muck and grit. Finished in a brilliant gold to bring factory-level swagger to your machine, the 428 RX3 gives lightweight racers the efficiency, durability and reliability needed to take the holeshot.
