The Regina 520 RX3 is a high-performance off-road drive chain designed for motorcycles exposed to severe riding conditions. This 114-link chain combines lightweight construction with the strength and durability needed for demanding trail, motocross, enduro, and other off-road applications. The chain is supplied with a clip-type connecting link for installation and service convenience.
Specially shaped bushings and chromized pins help reduce chain elongation while improving resistance to wear. Larger-diameter alloy carbon steel pins and thicker plates provide increased tensile strength and better fatigue resistance under repeated impacts and high-load operation. Shot-peened components further enhance durability, making the Regina 520 RX3 a dependable choice for riders who need consistent drivetrain performance in harsh environments.
Extended bushings and solid rollers improve service life, while beveled inner links promote smoother sprocket engagement, even when riding conditions are difficult. The 520 size is commonly used on off-road motorcycles and other compatible powersports applications, but fitment should be confirmed against the manufacturer’s specifications, sprocket setup, and required chain length. Manufactured by Regina and identified by manufacturer and vendor part number 135RX3/00A.
