Optimal tooth thickness results in maximum tooth and chain contact. We leave the cleaning grooves out of our sprockets, because more aluminum contacting your chain means longer chain and sprocket life. Moose Racing rear sprockets come anodized in black; select rear sprockets are available in red, orange and blue. Made in the USA.\u003cbr\u003e\u003cbr\u003eVehicle Fitment:\u003cbr\u003e\u003cbr\u003e2008-2013 Yamaha YFM250 Raptor\u003cbr\u003e 2004-2013 Yamaha YFM350 Raptor\u003cbr\u003e 1987-2004 Yamaha YFM350X Warrior\u003cbr\u003e 2013-2019 Yamaha YFM700 Raptor\u003cbr\u003e 1989-2006 Yamaha YFZ350 Banshee\u003cbr\u003e 2004-2009 Yamaha YFZ450\u003cbr\u003e 2012-2013 Yamaha YFZ450","brand":"Moose Racing","offers":[{"title":"Default Title","offer_id":44131152658554,"sku":"8455879","price":40.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/3312\/7455\/files\/bfae486b2c1f4d93a85334a59c1fe2d0_521505be-5e29-4465-8ece-9958a5e88d53.jpg?v=1780387986","url":"https:\/\/www.powersportsuperstore.com\/products\/moose-racing-1857-40al-aluminum-rear-sprocket-40t","provider":"Powersport Superstore","version":"1.0","type":"link"}
