This 120-link chain features Regina’s advanced Tetrahedral Amorphous Carbon (ta-C) coating, a 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 operation, reduce energy loss, and improve drivetrain efficiency.\u003c\/p\u003e\u003cp\u003eDesigned to eliminate the need for periodic chain lubrication, the Regina 520 HPE can provide mileage comparable to a conventional chain that is regularly lubricated every 310 miles, while helping reduce maintenance time and mess. Its dry-running design helps prevent lubricant spatter on the motorcycle and reduces spending on chain lubricant, cleaning products, and related maintenance supplies. The environmentally friendly construction also supports cleaner motorcycle maintenance.\u003c\/p\u003e\u003cp\u003eFor proper installation and performance, the drive chain should be used with steel sprockets. Special sprocket coatings are not required. The chain is intended for compatible medium- and small-displacement motorcycle applications; confirm the motorcycle’s required 520 chain size, link count, and manufacturer fitment specifications before installation. This product is manufactured by Regina and is identified by manufacturer and vendor part number 135HPE\/1009.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSize: 520 drive chain with 120 links\u003c\/li\u003e\n\u003cli\u003eModel: HPE\u003c\/li\u003e\n\u003cli\u003eBrand: Regina\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: 135HPE\/1009\u003c\/li\u003e\n\u003cli\u003eVendor part number: 135HPE\/1009\u003c\/li\u003e\n\u003cli\u003eApplication: Medium- and small-displacement motorcycles\u003c\/li\u003e\n\u003cli\u003eCoating: Tetrahedral Amorphous Carbon (ta-C), an advanced Diamond Like Carbon treatment\u003c\/li\u003e\n\u003cli\u003eMaintenance: Eliminates the need for periodic chain lubrication\u003c\/li\u003e\n\u003cli\u003ePerformance: High hardness and low friction help reduce energy dissipation and improve drivetrain efficiency\u003c\/li\u003e\n\u003cli\u003eFitment: Requires compatible 520 sprockets made of steel; verify motorcycle specifications before installation\u003c\/li\u003e\n\u003cli\u003eEnvironmental benefit: Reduces lubricant use, cleaning requirements, and lubricant spatter\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REGINA","offers":[{"title":"Default Title","offer_id":67547631288555,"sku":"12240247","price":374.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/2723870.png?v=1790679858","url":"https:\/\/ctracingservices.com\/products\/regina-520-hpe-drive-chain-120-links-part-number-135hpe-1009","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
