This 120-link chain uses Regina’s patented Z44 sealing rings to help retain lubricant and protect critical internal components from contamination. Its 525-size configuration is suitable for compatible motorcycle and powersports drivetrains; verify the vehicle manufacturer’s fitment requirements before installation.\u003c\/p\u003e\u003cp\u003eSpecial high-temperature grease provides continuous lubrication around the pin and bushing area, helping reduce maintenance needs and prolonging service life. Compared with conventional O-ring chains, the ZRT design reduces friction by up to 50 percent, supporting smoother operation and efficient drivetrain performance. High-carbon alloy pins help minimize wear, while increased roller thickness contributes to improved durability under demanding riding conditions.\u003c\/p\u003e\u003cp\u003eThe chain features thicker outer plates and quad-riveted construction for increased tensile strength and reliable load handling. A rivet-type master link is included for secure installation. Manufactured by Regina and identified by manufacturer and vendor part number 137ZRT\/016, this chain is a practical replacement for compatible 525 chain applications requiring 120 links and enhanced sealing performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSize: 525 drive chain with 120 links\u003c\/li\u003e\n\u003cli\u003eModel: ZRT\u003c\/li\u003e\n\u003cli\u003eBrand: Regina\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: 137ZRT\/016\u003c\/li\u003e\n\u003cli\u003eVendor part number: 137ZRT\/016\u003c\/li\u003e\n\u003cli\u003eSealing technology: Patented Z44 sealing rings help improve wear life and contamination resistance\u003c\/li\u003e\n\u003cli\u003eFriction reduction: Up to 50 percent less friction than traditional O-ring chains\u003c\/li\u003e\n\u003cli\u003eLubrication: High-temperature grease maintains lubrication in the pin and bushing area\u003c\/li\u003e\n\u003cli\u003eConstruction: High-carbon alloy pins and thicker rollers help minimize wear\u003c\/li\u003e\n\u003cli\u003eStrength: Thicker outer plates and quad-riveting improve tensile strength\u003c\/li\u003e\n\u003cli\u003eInstallation: Rivet-type master link included\u003c\/li\u003e\n\u003cli\u003eFitment: Designed for compatible motorcycle and powersports applications using a 525-size, 120-link drive chain\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REGINA","offers":[{"title":"Default Title","offer_id":67545793560811,"sku":"12240119","price":220.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/180981.png?v=1790672411","url":"https:\/\/ctracingservices.com\/products\/regina-525-zrt-drive-chain-120-links-part-number-137zrt-016","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
