Crafted with a high-strength Ultralight™ 7075 T-6 aluminum inner ring, this sprocket offers exceptional strength while minimizing weight. The outer ring is made of electro-less nickel coated steel for maximum durability, ensuring longevity even under harsh riding conditions. The outer ring is expanded at 200°C and then precisely fitted over the inner ring, creating a secure interference fit that guarantees a permanent bond for the life of the chainwheel. This design provides reliable performance and resistance to wear, making it ideal for demanding riding environments. The wave pattern on the outer ring further enhances the strength and integrity of the sprocket, while the flat socket head screws add additional impact resistance and eliminate contact with the chain guide, reducing potential damage during side impacts. \u003cbr\u003eSelf-cleaning mud grooves between each tooth prevent dirt and debris buildup, which helps reduce chainwheel wear and maintains optimal performance. This feature also contributes to lighter weight by minimizing unnecessary material. The Renthal Twinring™ rear sprocket is built to outlast a standard all-aluminum sprocket by three times, yet remains significantly lighter than an all-steel rear sprocket, offering a perfect balance of durability and weight savings. With its innovative design and premium materials, this sprocket is ideal for riders seeking longevity, strength, and efficiency in their motorcycle drivetrain components.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eInner ring made of high-strength Ultralight™ 7075 T-6 aluminum for optimal strength-to-weight ratio\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOuter ring of electro-less nickel coated steel for enhanced durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eExpanded at 200°C and interference fitted for a permanent, secure bond\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eWave pattern on outer ring increases strength and longevity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFlat socket head screws provide impact resistance and prevent contact with chain guide\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSelf-cleaning mud grooves between teeth reduce dirt buildup and wear\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned to last three times longer than standard all-aluminum sprockets\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLighter than all-steel rear sprockets for improved performance\u003c\/li\u003e\u003c\/ul\u003e","brand":"RENTHAL","offers":[{"title":"Default Title","offer_id":45191659094211,"sku":"12100816","price":142.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/renthal-twinring-rear-sprocket-50-tooth-black-2240-520-50gpbk-7209895.png?v=1781199426","url":"https:\/\/kellymotorsport.com\/products\/renthal-twinring%e2%84%a2-rear-sprocket-50-tooth-black-2240-520-50gpbk","provider":"Kelly Motorsports","version":"1.0","type":"link"}
