The Regina 520 HPE drive chain is engineered for medium- and small-displacement motorcycles requiring efficient, low-maintenance power transmission. This 114-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 operation and improved 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 reduce maintenance time. The dry-running design limits lubricant spatter on the motorcycle, reduces spending on chain lubricant, fuel, and bike cleaners, and offers an environmentally conscious alternative to traditional chain maintenance.
For proper installation and service life, use steel sprockets with this chain. Special sprocket coatings are not required. Confirm that the 520 chain size, 114-link length, and motorcycle application match the manufacturer’s fitment requirements before installation. This Regina chain is identified by manufacturer part number 135HPE/1006 and vendor part number 135HPE/1006.
