This 104-link chain uses Regina’s Tetrahedral Amorphous Carbon (ta-C) coating, an advanced Diamond Like Carbon (DLC) surface treatment applied to the bushings and rollers. The coating combines high hardness with a low coefficient of friction to support smooth, efficient power transfer and dependable service.\u003c\/p\u003e\u003cp\u003eUnlike a conventional motorcycle chain that requires regular lubrication, the Regina 520 HPE is engineered to eliminate periodic re-lubrication while delivering at least comparable mileage to a normally lubricated chain maintained every 310 miles. Reduced lubricant use helps minimize maintenance time, prevent lube spatter from collecting on the motorcycle, and lower ongoing spending on chain lubricant, fuel consumption, and bike-cleaning products. The design also supports more power reaching the rear wheel by reducing energy dissipation in the drive system.\u003c\/p\u003e\u003cp\u003eFor proper fitment and performance, this Regina 520 HPE chain must be used with steel sprockets. Special sprocket coatings are not required. Verify that the motorcycle manufacturer’s application, chain size, and required link count match this 104-link configuration before installation. The manufacturer part number is 135HPE\/1001, and the vendor part number is 135HPE\/1001.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSize: 520 motorcycle drive chain with 104 links\u003c\/li\u003e\n\u003cli\u003eModel: HPE\u003c\/li\u003e\n\u003cli\u003eBrand: Regina\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number: 135HPE\/1001\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: 135HPE\/1001\u003c\/li\u003e\n\u003cli\u003eApplication: Designed for medium- and small-displacement motorcycles\u003c\/li\u003e\n\u003cli\u003eLow Maintenance: Eliminates the need for periodic chain re-lubrication\u003c\/li\u003e\n\u003cli\u003eCoating: Tetrahedral Amorphous Carbon (ta-C) DLC coating on the bushings and rollers\u003c\/li\u003e\n\u003cli\u003eEfficiency: Low coefficient of friction helps reduce energy dissipation and improve drive efficiency\u003c\/li\u003e\n\u003cli\u003eFitment Requirement: Use with steel sprockets; special sprocket coatings are not required\u003c\/li\u003e\n\u003cli\u003eEnvironmental Benefit: Reduces lubricant use and lube-related cleaning requirements\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REGINA","offers":[{"title":"Default Title","offer_id":67547618279659,"sku":"12240239","price":279.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/2725538.png?v=1790679542","url":"https:\/\/ctracingservices.com\/products\/regina-520-hpe-drive-chain-104-links-part-number-135hpe-1001","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
