The Regina 525 HPE drive chain is designed for motorcycle applications requiring efficient, low-maintenance power transmission. This 110-link chain features Regina’s Tetrahedral Amorphous Carbon (ta-C) coating, an advanced Diamond Like Carbon (DLC) treatment applied to the bushing and roller surfaces. The coating combines high hardness with a low coefficient of friction to support smooth operation, durability, and consistent performance.
Designed to reduce routine maintenance, the Regina 525 HPE can eliminate the need for periodic re-lubrication while targeting mileage comparable to a conventional chain that is regularly lubricated every 310 miles. Reduced friction helps minimize energy dissipation and improve chain-drive efficiency, delivering more power to the rear wheel while potentially reducing lubricant, fuel, and motorcycle-cleaning expenses.
The coated surfaces also help eliminate lubricant spatter during operation, making the Regina HPE chain a cleaner and more environmentally considerate option. This chain is intended for use with steel sprockets only and should be selected for compatible motorcycle applications using a 525-size chain and the required 110-link length. The manufacturer is Regina, and the vendor part number is 137HPE/1002.
