Description
This is top of the line gold non O-ring motocross chain. Designed and developed to withstand the severe stresses caused by Motocross riding and racing. Larger diameter alloy carbon steel pins and thicker plates offer increased tensile strength and fatigue resistance. RX chains feature extended bushings, solid rollers, shaped bushings, and special chromized alloy carbon steel pins. Shaped bushings feature a “barrel” effect that occurs when a standard bushing is assembled. The result is full contact between bushing and pins along the entire length, with a subsequent reduction in specific contact pressure and hence, reduction in wear. The pins have exceptional surface hardness through a special chromizing treatment. This translates into maximum wear resistance.
428 chains feature the same technology as the 520 non O-ring chains and are available in 130 link.
