The Regina 520 HPE Drive Chain is engineered for medium- and small-displacement motorcycles that use a 520 chain size and compatible 112-link configuration. Manufacturer part number 135HPE/1005 and vendor part number 135HPE/1005 identify this chain for accurate replacement and fitment selection. Before installation, confirm that your motorcycle requires a 520 chain, accommodates 112 links, and uses steel sprockets as specified by Regina.
Regina HPE technology is designed to eliminate the need for periodic chain re-lubrication while providing mileage performance comparable to a conventional chain that is regularly lubricated every 310 miles. By reducing lubricant fling, the chain helps minimize cleanup around the motorcycle and may reduce spending on chain lubricant, fuel consumption, and bike-cleaning products. Its maintenance-focused design is also an environmentally responsible choice for riders seeking a cleaner drivetrain.
The chain uses a Tetrahedral Amorphous Carbon (ta-C) coating, an advanced Diamond Like Carbon (DLC) treatment applied to the bushing and roller surfaces. This coating combines high hardness with a low coefficient of friction to reduce energy dissipation and improve drive efficiency. For proper operation, Regina specifies the use of steel sprockets; special sprocket coatings are not required. Verify motorcycle manufacturer recommendations and chain length before installation.
