The Regina 520RH2 drive chain is engineered for the severe demands of off-road riding. Designed for supermoto and motocross motorcycles up to 500cc, this 110-link chain delivers dependable power transmission and durable performance in demanding riding conditions. The chain uses larger-diameter alloy carbon steel pins and thicker plates to provide increased tensile strength and improved resistance to fatigue.
Extended bushings and solid rollers help improve durability by supporting smooth, consistent movement through the drivetrain. The included clip-type master link simplifies installation and provides a practical connection solution for compatible motorcycle applications. With its 520 size and 110-link configuration, the Regina 520RH2 is suited for replacement or drivetrain service when the motorcycle’s original equipment specifications call for this chain type and length.
Manufacturer and vendor part number 135RH2/1002 identifies this Regina chain for ordering and application reference. Confirm the motorcycle’s model, engine size, chain size, required link count, and master-link style before installation. Proper fitment also depends on the motorcycle’s sprocket configuration and manufacturer recommendations.
