The Regina 520 RX3 off-road drive chain is engineered for demanding dirt-bike and off-road riding conditions. Designed to handle severe loads while maintaining a lightweight construction, this 116-link chain delivers dependable performance, reduced elongation, and extended service life. The chain is suitable for compatible motorcycle and powersports applications using a 520-size drive chain and should be matched to the manufacturer’s specified sprocket configuration.
Specially shaped bushings and chromized pins help minimize elongation and improve wear resistance during prolonged use. Larger-diameter alloy carbon steel pins and thicker plates are shot-peened to increase tensile strength and improve resistance to fatigue caused by repeated impacts, high loads, and challenging terrain. Extended bushings and solid rollers further reinforce the chain’s durability for serious off-road operation.
Beveled inner links promote smoother sprocket engagement, even when riding conditions are harsh or the drivetrain is exposed to dirt and debris. A clip-type connecting link is included for installation. This Regina 520 RX3 chain is identified by manufacturer part number 135RX3/00B and vendor part number 135RX3/00B. Confirm chain size, link count, sprocket compatibility, and motorcycle fitment before installation.
