The Regina 520 ZRA drive chain is a durable, high-performance chain designed for motorcycle and powersports applications requiring dependable power transfer. This 120-link chain is manufactured from high-carbon alloy steel for strength, wear resistance, and long service life. Its 520 model sizing supports compatible 520 chain-drive systems when matched to the vehicle manufacturer’s specifications.
Shot-peened rollers, pins, and plates help improve fatigue resistance and durability under demanding operating conditions. Solid bushings support consistent engagement with the sprockets, while the pre-stretched construction helps minimize initial elongation and promotes stable performance after installation. The chain’s design is suited for replacement or service applications where reliable fit and efficient drivetrain operation are required.
