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.\u003c\/p\u003e\u003cp\u003eSpecially 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.\u003c\/p\u003e\u003cp\u003eInner 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.
