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. It is designed to reduce parasitic friction by eliminating internal O-rings, sending direct power from the countershaft to the rear sprocket. Oversized alloy carbon steel pins with an advanced chromized coating help limit wear and elongation under hard use. Curl-formed bushings and shot-peened solid rollers improve fatigue resistance in punishing conditions, while beveled inner link plates promote smooth sprocket engagement in mud and grit. Finished in gold, the 428 RX3 delivers the efficiency, durability and reliability lightweight racers need off the line and through the final moto.
