Designed for MX 85 applications, this 48-tooth sprocket combines a hardened, nickel-coated steel outer ring with an aircraft-grade 7075-T6 aluminum carrier to deliver a strong, lightweight solution for demanding motocross use. The black finish provides a clean, professional appearance while supporting long-lasting performance.\u003cbr\u003eThe specialized dual-ring construction is engineered to outlast a conventional aluminum sprocket by up to three times while weighing approximately 50% less than a standard steel sprocket. The precisely manufactured outer ring and carrier permanently interlock through a specialized heat-shrink procedure, creating a secure assembly designed to maintain alignment and durability under repeated acceleration, braking, and suspension movement.\u003cbr\u003eMOTO-MASTER uses CAD design, CNC machining, and laser-cutting technology to produce the Fusion Series sprocket with consistent accuracy. The carrier is color anodized for additional surface durability and resistance to wear, while the nickel-coated outer ring helps protect the sprocket from the harsh conditions commonly encountered on motocross tracks. This combination of materials and manufacturing methods provides a balanced blend of reduced rotating weight, dependable strength, and extended service life.\u003cbr\u003eSelect the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket when you need a high-performance replacement engineered specifically for MX 85 motorcycles. Verify fitment, chain compatibility, and final-drive requirements before installation. Professional installation and proper chain adjustment are recommended to help maximize sprocket life and drivetrain performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e48-tooth rear sprocket designed for MX 85 applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHardened, nickel-coated steel outer ring for enhanced durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned to outlast an aluminum sprocket by up to three times\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApproximately 50% lighter than a conventional steel sprocket\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAircraft-grade 7075-T6 aluminum carrier\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSpecialized heat-shrink procedure permanently interlocks the outer ring and carrier\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eColor anodized carrier coating for added durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCAD designed, CNC machined, and laser cut for precise manufacturing\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBlack finish\u003c\/li\u003e\u003c\/ul\u003e\r\n\u003cp\u003eShips from Parts Unlimited.\u003c\/p\u003e","brand":"Moto-Master","offers":[{"title":"Default Title","offer_id":60117212135710,"sku":"620183248","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1091\/7884\/7518\/files\/5574199.png?v=1791101564","url":"https:\/\/shoplepier.com\/products\/moto-master-fusion-series-dual-ring-rear-sprocket-48-tooth-black-mx-85-part-620183248","provider":"LEPIER POWERSPORTS","version":"1.0","type":"link"}
