This gold-finished chain includes 120 links and a rivet-type master link for secure installation. Manufacturer part number 137ZRP\/00F and vendor part number 137ZRP\/00F identify this Regina replacement chain for compatible motorcycle applications.\u003c\/p\u003e\u003cp\u003ePatented Z44 sealing rings help reduce friction and improve resistance to wear compared with traditional O-ring chain designs. Special high-temperature grease remains concentrated in the critical pin and bushing areas, supporting smooth operation and extended service life. High-carbon alloy pins help minimize wear, while increased roller thickness improves durability during demanding street and performance riding.\u003c\/p\u003e\u003cp\u003eFeature: Thicker outer plates and quad-riveting increase tensile strength and help the chain withstand the loads produced by high-performance motorcycles. The 525 chain configuration and 120-link length make it suitable for applications requiring this specific fitment; always verify the motorcycle model, year, original chain specification, and required final-drive length before installation. The included rivet-type link should be installed using the proper chain riveting tool and manufacturer-recommended procedure.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e525 chain size with 120 links for compatible street bikes and superbikes\u003c\/li\u003e\n\u003cli\u003eRegina Z44 sealing rings help reduce friction and extend wear life\u003c\/li\u003e\n\u003cli\u003eHigh-temperature grease supports continuous lubrication at the pin and bushing areas\u003c\/li\u003e\n\u003cli\u003eHigh-carbon alloy pins and thicker rollers improve durability\u003c\/li\u003e\n\u003cli\u003eThicker outer plates and quad-riveting increase tensile strength\u003c\/li\u003e\n\u003cli\u003eRivet-type master link included\u003c\/li\u003e\n\u003cli\u003eGold finish\u003c\/li\u003e\n\u003cli\u003eManufacturer and vendor part number: 137ZRP\/00F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REGINA","offers":[{"title":"Default Title","offer_id":67546999259371,"sku":"12240032","price":318.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/180975.png?v=1790676337","url":"https:\/\/ctracingservices.com\/products\/regina-525-zrp-drive-chain-120-links-gold-part-137zrp-00f","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
