Crafted with an inner ring made from premium Ultralight™ 7075 T-6 aluminum, this sprocket ensures strength while minimizing weight. The outer ring is constructed from electro-less nickel coated steel, providing superior durability and resistance to wear. The manufacturing process involves expanding the outer ring at 200°C and fitting it over the inner ring with an interference fit, creating a permanent bond that withstands rigorous riding conditions. The wave pattern design further enhances longevity by distributing stress evenly across the sprocket. \u003cbr\u003e Self-cleaning mud grooves between each tooth prevent dirt accumulation, reducing chainwheel wear and maintaining optimal performance during muddy or dusty rides. The flat socket head screws reinforce the sprocket's integrity during side impacts and prevent contact with chain guides, ensuring reliable operation. This design results in a sprocket that lasts up to three times longer than standard all-aluminum counterparts, yet remains significantly lighter than traditional steel sprockets. \u003cbr\u003e Whether you're racing or trail riding, the Renthal Twinring™ 49 Tooth Rear Sprocket delivers exceptional strength, durability, and weight savings, making it an ideal choice for demanding riders seeking longevity and performance in a sleek, blue finish.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eInner ring made from Ultralight™ 7075 T-6 aluminum for strength and light weight\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOuter ring is electro-less nickel coated steel for durability and wear resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInterference fit with wave pattern ensures a permanent, secure bond\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\u003eFlat socket head screws add strength during side impacts and prevent contact with chain guide\u003c\/li\u003e\u003c\/ul\u003e","brand":"RENTHAL","offers":[{"title":"Default Title","offer_id":45191658963139,"sku":"12100818","price":149.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/renthal-twinring-49-tooth-rear-sprocket-for-yamaha-blue-part-1500-520-49gpbu-6089496.png?v=1781199426","url":"https:\/\/kellymotorsport.com\/products\/renthal-twinring%e2%84%a2-49-tooth-rear-sprocket-for-yamaha-blue-part-1500-520-49gpbu","provider":"Kelly Motorsports","version":"1.0","type":"link"}
