Computer engineered and tested to ensure a precise fitment, concentricity and load dispersion with tooth profiling to provide maximum power transfer.  A combination of high strength base material, cutting edge manufacturing methods and exceptional hardwearing surface treatments its clear to see why Renthal's light weight all aluminum rear sprockets can be found on the rear wheels of many factory race team machines.\n\u003cp\u003eThe Renthal UltraLight Rear Chainwheel is engineered for high-performance powersports applications, specifically designed to optimize power transfer and durability. Crafted from CNC-machined 7075 T6 aluminum, this sprocket offers a significant reduction in weight—approximately 66% lighter than traditional steel counterparts—without compromising strength or reliability. Its lightweight construction makes it an ideal choice for racing and aggressive riding, where minimizing unsprung weight can enhance handling and acceleration. The computer-engineered design ensures a precise fit, maintaining perfect concentricity and even load distribution across the tooth profile, which helps extend the lifespan of both the sprocket and the chain. Features include a hardwearing surface treatment that resists wear and corrosion, making it suitable for demanding riding conditions and prolonged use. This sprocket is compatible with various Yamaha YZ80 models from 1989 to 2001 and the Suzuki RM80 from 1989, ensuring a perfect fit for these popular dirt bikes. Its grooved design provides optimal chain engagement, reducing slippage and ensuring maximum power transfer to the rear wheel for competitive riding or recreational fun.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eMaterial: CNC machined from 7075 T6 aluminum for strength and lightweight performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eWeight: 66% lighter than steel sprockets, reducing unsprung weight for improved handling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesign: Computer engineered for precise fit, concentricity, and load dispersion\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSurface Treatment: Hardwearing finish for enhanced durability and corrosion resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatibility: Fits Yamaha YZ80 (1989-2001) and Suzuki RM80 (1989)\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\nSuzuki RM80 Base 1989\u003cbr\u003e\nSuzuki RM80 Base 1990\u003cbr\u003e\nSuzuki RM80 Base 1991\u003cbr\u003e\nSuzuki RM80 Base 1992\u003cbr\u003e\nSuzuki RM80 Base 1993\u003cbr\u003e\nSuzuki RM80 Base 1994\u003cbr\u003e\nSuzuki RM80 Base 1995\u003cbr\u003e\nSuzuki RM80 Base 1996\u003cbr\u003e\nSuzuki RM80 Base 1997\u003cbr\u003e\nSuzuki RM80 Base 1998\u003cbr\u003e\nSuzuki RM80 Base 1999\u003cbr\u003e\nSuzuki RM80 Base 2000\u003cbr\u003e\nSuzuki RM80 Base 2001\u003cbr\u003e\nSuzuki RM85 Base 2002\u003cbr\u003e\nSuzuki RM85 Base 2003\u003cbr\u003e\nSuzuki RM85 Base 2004\u003cbr\u003e\nSuzuki RM85 Base 2005\u003cbr\u003e\nSuzuki RM85 Base 2006\u003cbr\u003e\nSuzuki RM85 Base 2007\u003cbr\u003e\nSuzuki RM85 Base 2008\u003cbr\u003e\nSuzuki RM85 Base 2009\u003cbr\u003e\nSuzuki RM85 Base 2012\u003cbr\u003e\nSuzuki RM85 Base 2015\u003cbr\u003e\nSuzuki RM85 Base 2016\u003cbr\u003e\nSuzuki RM85 Base 2017\u003cbr\u003e\nSuzuki RM85 Base 2018\u003cbr\u003e\nSuzuki RM85 Base 2019\u003cbr\u003e\nSuzuki RM85 Base 2020\u003cbr\u003e\nSuzuki RM85 Base 2021\u003cbr\u003e\nSuzuki RM85L Base 2003\u003cbr\u003e\nSuzuki RM85L Base 2004\u003cbr\u003e\nSuzuki RM85L Base 2005\u003cbr\u003e\nSuzuki RM85L Base 2006\u003cbr\u003e\nSuzuki RM85L Base 2007\u003cbr\u003e\nSuzuki RM85L Base 2008\u003cbr\u003e\nSuzuki RM85L Base 2012\u003cbr\u003e\nYamaha YZ80 Base 1993\u003cbr\u003e\nYamaha YZ80 Base 1994\u003cbr\u003e\nYamaha YZ80 Base 1995\u003cbr\u003e\nYamaha YZ80 Base 1996\u003cbr\u003e\nYamaha YZ80 Base 1997\u003cbr\u003e\nYamaha YZ80 Base 1998\u003cbr\u003e\nYamaha YZ80 Base 1999\u003cbr\u003e\nYamaha YZ80 Base 2000\u003cbr\u003e\nYamaha YZ80 Base 2001\u003cbr\u003e\nYamaha YZ85 Base 2002\u003cbr\u003e\nYamaha YZ85 Base 2003\u003cbr\u003e\nYamaha YZ85 Base 2004\u003cbr\u003e\nYamaha YZ85 Base 2005\u003cbr\u003e\nYamaha YZ85 Base 2006\u003cbr\u003e\nYamaha YZ85 Base 2007\u003cbr\u003e\nYamaha YZ85 Base 2008\u003cbr\u003e\nYamaha YZ85 Base 2009\u003cbr\u003e\nYamaha YZ85 Base 2010\u003cbr\u003e\nYamaha YZ85 Base 2011\u003cbr\u003e\nYamaha YZ85 Base 2012\u003cbr\u003e\nYamaha YZ85 Base 2013\u003cbr\u003e\nYamaha YZ85 Base 2014\u003cbr\u003e\nYamaha YZ85 Base 2015\u003cbr\u003e\nYamaha YZ85 Base 2016\u003cbr\u003e\nYamaha YZ85 Base 2017\u003cbr\u003e\nYamaha YZ85 Base 2018\u003cbr\u003e\nYamaha YZ85 Base 2019\u003cbr\u003e\nYamaha YZ85 Base 2020\u003cbr\u003e\nYamaha YZ85 Base 2021","brand":"Renthal","offers":[{"title":"Default Title","offer_id":53943350591804,"sku":"ren121U-428-48GPSI","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1865\/9007\/files\/7805a97f0bbb744bb1ab2789ff2d804e_6e4e5d53-c70e-4d7a-bcc1-65920fe1c5f9.jpg?v=1785192177","url":"https:\/\/necycleshop.com\/products\/renthal-89-01-suzuki-rm-80-2002-yamaha-yz85-rear-grooved-sprocket-silver-428-48p-teeth-1","provider":"NE Cycle Shop","version":"1.0","type":"link"}
