The Regina 525 HPE drive chain is a high-performance motorcycle chain designed for applications requiring durable, efficient power transfer. This 128-link chain uses Regina’s advanced tetrahedral amorphous carbon (ta-C) coating on the bushings and rollers. The coating combines high hardness with a low coefficient of friction to support smooth operation, reduce drivetrain energy loss, and improve power delivery to the rear wheel.
Unlike a conventional chain that requires regular lubrication, the Regina 525 HPE is engineered to eliminate periodic re-lubrication while providing at least the same mileage achieved by a standard chain lubricated every 310 miles. Its low-friction construction helps reduce lubricant spatter during operation, helping keep the motorcycle cleaner and minimizing environmental impact. Riders may also benefit from reduced spending on chain lubricant, fuel consumption, and bike-cleaning products.
This Regina chain is intended for motorcycle drive systems using steel sprockets only. Verify that the 525 chain size, 128-link length, and Regina part number 137HPE/1010 match the motorcycle’s original equipment specifications and sprocket configuration before installation. Manufacturer: Regina. Vendor part number: 137HPE/1010. The chain is supplied as a drive-chain component for compatible motorcycle applications; installation should follow the motorcycle manufacturer’s service procedures.
