The Regina 525 HPE drive chain is engineered for high-performance motorcycle applications requiring reduced friction, extended service intervals, and reliable power transmission. This 112-link chain uses Regina’s advanced Tetrahedral Amorphous Carbon (ta-C) coating on the bushings and rollers. The coating combines high hardness with a low coefficient of friction to help reduce energy loss throughout the chain drive and deliver more power to the rear wheel.
Designed to minimize maintenance, the Regina 525 HPE can eliminate the need for periodic re-lubrication while providing at least the same mileage achieved by a conventional chain lubricated every 310 miles. Its low-friction construction also helps reduce lubricant spatter during operation, which can keep the motorcycle cleaner and lower lubricant-related environmental impact. Riders can benefit from reduced spending on chain lubricant, fuel consumption, and motorcycle cleaning products.
This Regina 525 HPE chain is intended for motorcycle fitments using compatible 525-size chain and steel sprockets only. Confirm the motorcycle manufacturer’s application requirements, chain length, and sprocket compatibility before installation. The product is identified by Regina manufacturer part number 137HPE/1003 and vendor part number 137HPE/1003. Proper installation and alignment are recommended to support dependable operation and maximize chain life.
