Crafted with an inner ring made from high-strength Ultralight™ 7075 T-6 aluminum, this sprocket offers exceptional strength while minimizing weight. The outer ring, composed of electro-less nickel coated steel, is designed to withstand harsh riding conditions and deliver long-lasting durability. The manufacturing process involves expanding the outer ring at 200°C and fitting it over the inner ring with an interference fit, complemented by a wave pattern that ensures a permanent bond for the lifespan of the chainwheel. This construction provides a secure, enduring connection that resists impact and wear. The flat socket head screws add extra strength during side impacts and prevent contact with the chain guide, ensuring reliable performance. Self-cleaning mud grooves between each tooth help prevent dirt buildup, reduce wear, and lower weight, making it ideal for off-road and motocross applications. This sprocket is built to outperform standard all-aluminum sprockets by three times in lifespan, while remaining significantly lighter than all-steel options, offering a perfect balance of strength and weight savings for demanding riders. Whether you're replacing a worn sprocket or upgrading for improved performance, the Renthal Twinring™ 49 Tooth Rear Sprocket provides unmatched durability and efficiency for Honda bikes.\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 strength and reduced weight\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOuter ring is electro-less nickel coated steel for enhanced durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eManufactured with an interference fit and wave pattern for a permanent bond\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFlat socket head screws provide additional 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, lowering weight\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 optimal performance and weight savings\u003c\/li\u003e\u003c\/ul\u003e","brand":"RENTHAL","offers":[{"title":"Default Title","offer_id":45191478476995,"sku":"12100812","price":142.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/184310.png?v=1779577889","url":"https:\/\/kellymotorsport.com\/products\/renthal-twinring%e2%84%a2-49-tooth-rear-sprocket-for-honda-black-part-1540-520-49gpbk","provider":"Kelly Motorsports","version":"1.0","type":"link"}
