Regina Chain 428 RX3 Series Chain

Regina Chain 428 RX3 Series Chain

The Regina 428 RX3 Series Chain is a non-sealed off-road competition chain built for motocross, supermoto and high-performance e-moto applications up to 125cc. With no internal O-rings, it reduces parasitic friction to send direct power from the countershaft to the rear sprocket. Made to handle hard landings and sudden torque spikes, the 428 RX3 uses oversized alloy carbon steel pins with an advanced chromized coating to limit wear and elongation. Curl-formed bushings, shot-peened solid rollers and beveled inner link plates help maintain strength and smooth sprocket engagement in mud, sand and grit. Finished in gold, it gives lightweight racers the efficiency, durability and reliability needed off the line and through the final moto.
