Laboratory tests have demonstrated that QX-rings reduce friction by 40 percent, extending chain lifespan by up to 50 percent compared to traditional O-ring chains. Additionally, weight-saving holes drilled into every other chain link minimize rotating mass without compromising strength, enhancing horsepower delivery to the rear wheel and improving throttle response.\n\u003cul\u003e\n  \u003cli\u003eCompatible displacement: Street - 750cc \/ Dirt - 650cc\u003c\/li\u003e\n  \u003cli\u003eSuitable for street, touring, or dirt motorcycles\u003c\/li\u003e\n  \u003cli\u003eWeight reducing holes for optimized performance\u003c\/li\u003e\n  \u003cli\u003eQX-ring technology for reduced friction\u003c\/li\u003e\n  \u003cli\u003eWeight per 100 links: 3.46 lbs\u003c\/li\u003e\n  \u003cli\u003eIncludes clip-type master link\u003c\/li\u003e\n  \u003cli\u003eTensile Strength - 8500 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe Vortex Racing EK 520 SRX2 Chain is engineered for high-performance motorcycle applications, offering exceptional durability and reduced friction for both street and off-road riding. Featuring advanced QX-ring technology, this chain outperforms traditional O-ring chains by decreasing friction by up to 40 percent, which translates into smoother power transfer and increased efficiency. Laboratory tests confirm that QX-rings significantly extend chain lifespan by approximately 50 percent, making this chain a reliable choice for riders seeking long-term performance and minimal maintenance. The chain includes drilled holes in every other link to reduce rotational weight, which enhances throttle response, accelerates power delivery, and improves overall handling without sacrificing strength or durability.\u003c\/p\u003e","brand":"Vortex Racing","offers":[{"title":"Default Title","offer_id":47974990807298,"sku":"755083","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0818\/3401\/7026\/files\/569cadb20d3a17fd6f442f15af0be8c9.png?v=1781114201","url":"https:\/\/teamkustom.shop\/products\/vortex-racing-ek-520-srx2-chain-with-qx-ring-technology-104-links-for-street-and-off-road-motorcycles","provider":"Teamkustom","version":"1.0","type":"link"}
