This 120-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, efficient operation and long-term durability.\u003c\/p\u003e\u003cp\u003eDesigned to reduce the need for periodic re-lubrication, the Regina 525 HPE can deliver at least the same mileage as a conventional chain that is regularly lubricated every 310 miles, when used under comparable conditions. Its low-friction construction helps reduce energy dissipation in the chain drive, allowing more power to reach the rear wheel while potentially reducing lubricant, fuel, and chain-cleaning expenses. The dry-running design also eliminates lubricant spatter during operation, helping keep the motorcycle and surrounding environment cleaner.\u003c\/p\u003e\u003cp\u003eThis Regina chain is intended for motorcycle final-drive applications compatible with a 525 chain size and requires steel sprockets. Verify motorcycle fitment, chain length, sprocket compatibility, and manufacturer recommendations before installation. The manufacturer part number is 137HPE\/1007, and the vendor part number is 137HPE\/1007. With its 120-link configuration, the chain may be suitable for a range of motorcycle models after confirming the correct length and drivetrain specifications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSize: 525 motorcycle drive chain with 120 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\/1007\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: 137HPE\/1007\u003c\/li\u003e\n\u003cli\u003eCoating: Tetrahedral Amorphous Carbon (ta-C), an advanced Diamond Like Carbon treatment\u003c\/li\u003e\n\u003cli\u003eLow Friction: Helps reduce energy dissipation and improve chain-drive efficiency\u003c\/li\u003e\n\u003cli\u003eMaintenance: Designed to eliminate the need for periodic re-lubrication under comparable operating conditions\u003c\/li\u003e\n\u003cli\u003eClean Operation: Eliminates lubricant spatter during use\u003c\/li\u003e\n\u003cli\u003eFitment: For compatible motorcycle final-drive systems using steel sprockets only\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REGINA","offers":[{"title":"Default Title","offer_id":67547640791275,"sku":"12240231","price":444.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/2573024.png?v=1790680040","url":"https:\/\/ctracingservices.com\/products\/regina-525-hpe-drive-chain-120-links-part-number-137hpe-1007","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
