The Regina 520 HPE drive chain is engineered for medium- and small-displacement motorcycles that require efficient, low-maintenance power transmission. This 110-link chain features Regina’s advanced Tetrahedral Amorphous Carbon (ta-C) coating, a specialized Diamond Like Carbon (DLC) surface treatment applied to the bushings and rollers. The coating combines high hardness with a low coefficient of friction to help reduce energy loss and improve drivetrain efficiency.
Designed to eliminate periodic chain lubrication, the Regina 520 HPE can provide mileage comparable to a conventional chain that is regularly lubricated every 310 miles, while helping prevent lubricant spatter from collecting on the motorcycle. Reduced maintenance can save time and lower ongoing expenses related to chain lubricant, fuel consumption, and motorcycle cleaning products. The environmentally friendly design also helps minimize the use of maintenance chemicals.
For proper fitment and performance, this Regina 520 HPE chain must be used with steel sprockets. Special sprocket coatings are not required. Verify that your motorcycle uses a 520-size, 110-link drive chain and is within the recommended medium- or small-displacement application range before installation. Manufactured by Regina and identified by manufacturer and vendor part number 135HPE/1004, this chain is a suitable replacement for compatible motorcycle drivetrains seeking durable, efficient, and low-maintenance operation.
