This 49-tooth sprocket is CNC-machined rather than stamped, allowing Renthal to produce a precise, computer-aided ultra-light design that helps reduce unsprung weight and improve acceleration and handling response.\u003cbr\u003eThe rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. Compared with a conventional steel sprocket, this advanced aluminum construction is 33% lighter, helping reduce drivetrain weight while maintaining the strength required for demanding riding conditions. The result is efficient power transfer without compromising performance or reliability.\u003cbr\u003eThe Renthal 131U-520-49GBSI also features a specialized tooth profile designed to help the chain roll smoothly onto and off the sprocket. This controlled chain engagement can support longer chain and sprocket wear, quieter operation, and more efficient power delivery. Its precision-machined construction and race-inspired design make it a practical performance upgrade for compatible Yamaha applications.\u003cbr\u003eFeature: CNC-machined construction for precise production and consistent performance\u003cbr\u003eFeature: Computer-aided ultra-light design helps reduce unsprung and rotating weight\u003cbr\u003eFeature: Enhanced 7075-T6 aluminum provides a strong, lightweight alternative to steel\u003cbr\u003eFeature: 49-tooth rear sprocket configuration for compatible Yamaha drivetrains\u003cbr\u003eFeature: Special tooth profile promotes smooth chain engagement, reduced noise, and longer wear\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eCNC-machined construction for precise production and consistent performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComputer-aided ultra-light design helps reduce unsprung and rotating weight\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnhanced 7075-T6 aluminum provides a strong, lightweight alternative to steel\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e49-tooth rear sprocket configuration for compatible Yamaha drivetrains\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSpecial tooth profile promotes smooth chain engagement, reduced noise, and longer wear\u003c\/li\u003e\u003c\/ul\u003e\r\n\u003cp\u003eShips from Parts Unlimited.\u003c\/p\u003e","brand":"Renthal","offers":[{"title":"Default Title","offer_id":60117530214686,"sku":"131U-520-49GBSI","price":99.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1091\/7884\/7518\/files\/185046.png?v=1791106797","url":"https:\/\/shoplepier.com\/products\/renthal-131u-520-49gbsi-rear-sprocket-for-yamaha-49-tooth","provider":"LEPIER POWERSPORTS","version":"1.0","type":"link"}
