The Regina 520 HPE drive chain is designed for medium- and small-displacement motorcycles requiring efficient, low-maintenance power transmission. This chain includes 102 links and is identified by manufacturer part number 135HPE/1000. The Regina HPE series uses an advanced Tetrahedral Amorphous Carbon (ta-C) coating, a Diamond-Like Carbon (DLC) surface treatment applied to the bushings and rollers to support high durability and reduced friction.
Engineered to reduce energy loss in the drive system, the Regina 520 HPE chain helps deliver more power to the rear wheel while supporting improved drivetrain efficiency. Its specialized coating eliminates the need for periodic chain lubrication under normal use, reducing lubricant consumption, cleaning requirements, and maintenance time. Compared with a conventional chain lubricated at regular 310-mile intervals, the HPE design is intended to provide comparable or improved service performance without lube spatter on the motorcycle.
This chain is suitable for compatible medium- and small-displacement motorcycle applications using a 520 chain size and a 102-link configuration. Installation should be completed with compatible steel sprockets; special sprocket coatings are not required. Verify the motorcycle manufacturer’s fitment specifications, chain length, sprocket condition, and joining-link requirements before installation. Regina part number 135HPE/1000 provides a direct reference for identifying this specific HPE chain configuration.
