This 118-link chain uses Regina’s Tetrahedral Amorphous Carbon (ta-C) coating on the bushings and rollers, combining high surface hardness with a low coefficient of friction. The result is efficient chain operation, reduced energy loss, and consistent power delivery from the engine to the rear wheel.\u003c\/p\u003e\u003cp\u003eUnlike conventional drive chains, the Regina 525 HPE is engineered to eliminate the need for periodic re-lubrication under applicable operating conditions. It is designed to provide at least the same mileage as a standard chain that is regularly lubricated every 310 miles, while reducing lubricant spatter during operation. This can help lower ongoing spending on chain lubricant, fuel consumption, and motorcycle cleaning products while minimizing the environmental impact associated with lubricant use.\u003c\/p\u003e\u003cp\u003eDesigned for motorcycle applications using compatible 525-size chain systems, this Regina model features 118 links and is intended for use with steel sprockets only. Confirm the motorcycle manufacturer’s fitment requirements, chain length, sprocket compatibility, and installation specifications before purchase. The manufacturer part number and vendor part number are both 137HPE\/1006.\u003c\/p\u003e\u003cp\u003eWith its advanced ta-C coating, low-friction design, and maintenance-conscious construction, the Regina 525 HPE provides a practical upgrade for compatible street, touring, and performance motorcycles. Professional installation and correct chain adjustment are recommended to support proper fit, service life, and drivetrain performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSize: 525 drive chain with 118 links\u003c\/li\u003e\n\u003cli\u003eModel: 525 HPE\u003c\/li\u003e\n\u003cli\u003eBrand: Regina\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number: 137HPE\/1006\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: 137HPE\/1006\u003c\/li\u003e\n\u003cli\u003eCoating: Tetrahedral Amorphous Carbon (ta-C) DLC coating on the bushings and rollers\u003c\/li\u003e\n\u003cli\u003eFriction: Low coefficient of friction helps reduce energy dissipation and improve drivetrain efficiency\u003c\/li\u003e\n\u003cli\u003eMaintenance: Designed to eliminate periodic re-lubrication under applicable operating conditions\u003c\/li\u003e\n\u003cli\u003eMileage: Engineered to deliver at least the mileage of a regularly lubricated conventional chain\u003c\/li\u003e\n\u003cli\u003eOperation: Reduces lubricant spatter during use\u003c\/li\u003e\n\u003cli\u003eCompatibility: For use with steel sprockets only\u003c\/li\u003e\n\u003cli\u003eFitment: Designed for compatible motorcycles using a 525-size chain system; verify application requirements before installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REGINA","offers":[{"title":"Default Title","offer_id":67547639808235,"sku":"12240230","price":376.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/2572986.png?v=1790679995","url":"https:\/\/ctracingservices.com\/products\/regina-525-hpe-drive-chain-118-links-part-number-137hpe-1006","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
