Crafted with precision, the inner ring is made from durable Ultralight™ 7075 T-6 aluminum, the same high-strength alloy used in Renthal's standard sprockets, ensuring reliable performance under demanding conditions. The outer ring is constructed from electro-less nickel-coated steel, providing exceptional durability and resistance to wear, while its minimal material design helps reduce overall weight. The manufacturing process involves expanding the outer ring at 200°C and fitting it over the inner, creating a robust interference fit combined with a wave pattern that guarantees a permanent bond for the lifecycle of the chainwheel. Flat socket head screws are integrated to enhance strength during side impacts and prevent contact with the chain guide, contributing to the sprocket's longevity and performance. Self-cleaning mud grooves between each tooth are designed to prevent dirt accumulation, which reduces chainwheel wear and maintains smooth operation. This sprocket is engineered to last three times longer than standard all-aluminum sprockets while remaining significantly lighter than traditional steel options, providing an optimal balance of strength, weight savings, and durability for aggressive riding or racing scenarios. Whether upgrading for improved longevity or reducing weight, the Renthal Twinring™ Rear Sprocket delivers superior performance and reliability tailored for high-mileage motorcycle enthusiasts.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eInner ring made from high-strength Ultralight™ 7075 T-6 aluminum for durability and weight savings\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOuter ring constructed from electro-less nickel-coated steel for enhanced wear resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eManufactured with an interference fit and wave pattern for a permanent, secure bond\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFlat socket head screws increase strength and prevent contact with chain guide\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSelf-cleaning mud grooves between teeth reduce dirt build-up and chainwheel wear\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEngineered to last three times longer than standard aluminum sprockets while being lighter than steel options\u003c\/li\u003e\u003c\/ul\u003e","brand":"RENTHAL","offers":[{"title":"Default Title","offer_id":45191456358595,"sku":"12100807","price":142.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/184300.png?v=1779576789","url":"https:\/\/kellymotorsport.com\/products\/renthal-twinring%e2%84%a2-rear-sprocket-49-tooth-black-for-kawasaki-and-suzuki-part-1230-520-49gpbk","provider":"Kelly Motorsports","version":"1.0","type":"link"}
