The Regina 520 RX3 is a high-performance off-road drive chain engineered for demanding riding conditions. Designed for motorcycles that experience severe shock loads, mud, dust, and frequent changes in terrain, this 120-link chain combines lightweight construction with the strength and durability required for serious off-road use. The Regina 520 RX3 is supplied with a clip-type connecting link for installation and is identified by manufacturer and vendor part number 135RX3/00D.
Specially shaped bushings and chromized pins help reduce chain elongation and improve wear resistance over extended service. Larger-diameter alloy carbon steel pins and thicker side plates provide increased tensile strength and improved fatigue resistance, while shot-peened components enhance durability under repeated impacts and high-load riding. Extended bushings and solid rollers further support reliable performance during demanding operation.
Inner links are beveled to promote smooth sprocket engagement, helping the chain track correctly even in difficult off-road conditions. The Regina 520 RX3 fits applications specified for a 520-size, 120-link motorcycle drive chain and should be matched to the motorcycle’s required chain size, length, sprocket configuration, and connecting-link style before installation. Proper alignment, lubrication, and adjustment are recommended for maximum chain life and consistent power transfer.
