Moto-Master Fusion Series Dual-Ring Rear Sprocket 50-Tooth Orange for GasGas, Husqvarna and KTM (620083550)

Upgrade your motorcycle’s final-drive performance with the MOTO-MASTER Fusion Series Dual-Ring Rear Sprocket, part number 620083550. Designed for select GasGas, Husqvarna, and KTM motorcycles, this 50-tooth rear sprocket combines a hardened, nickel-coated steel outer ring with an aircraft-grade 7075-T6 aluminum carrier. The result is a durable, lightweight sprocket assembly engineered for demanding off-road and performance riding applications.
The specialized dual-ring construction is manufactured for a precise interlock between the outer ring and carrier. A permanent heat-shrink procedure helps maintain a secure connection while reducing unnecessary weight compared with a conventional steel sprocket. The hardened nickel-coated steel outer ring is designed to provide extended wear resistance and can outlast an aluminum sprocket by up to three times, helping support consistent chain engagement over extended use.
The MOTO-MASTER Fusion Series sprocket is CAD designed, CNC machined, and laser cut using advanced manufacturing technology for accurate fit and dependable performance. The aluminum carrier features a color-anodized orange finish that adds durability and complements the motorcycle’s appearance. With its balanced combination of strength, reduced weight, and precision manufacturing, this rear sprocket is a practical replacement or performance upgrade for compatible GasGas, Husqvarna, and KTM applications.
