The Regina 525 HPE Drive Chain is a high-performance motorcycle chain designed for applications requiring efficient, low-maintenance power transfer. This 120-link chain uses 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, efficient operation and long-term durability.
Designed to reduce the need for periodic re-lubrication, the Regina 525 HPE can deliver at least the same mileage as a conventional chain that is regularly lubricated every 310 miles, when used under comparable conditions. Its low-friction construction helps reduce energy dissipation in the chain drive, allowing more power to reach the rear wheel while potentially reducing lubricant, fuel, and chain-cleaning expenses. The dry-running design also eliminates lubricant spatter during operation, helping keep the motorcycle and surrounding environment cleaner.
This Regina chain is intended for motorcycle final-drive applications compatible with a 525 chain size and requires steel sprockets. Verify motorcycle fitment, chain length, sprocket compatibility, and manufacturer recommendations before installation. The manufacturer part number is 137HPE/1007, and the vendor part number is 137HPE/1007. With its 120-link configuration, the chain may be suitable for a range of motorcycle models after confirming the correct length and drivetrain specifications.
