Moto-Master Fusion Series Dual Ring Rear Sprocket 47-Tooth Black (620083247)

Upgrade your motorcycle’s drivetrain with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, part number 620083247. Designed for select GasGas, Husqvarna, and KTM applications, this 47-tooth rear sprocket combines a hardened, nickel-coated steel outer ring with an aircraft-grade 7075-T6 aluminum carrier. The dual-ring construction is engineered to provide the durability of steel where wear is greatest while significantly reducing overall weight compared with a conventional steel sprocket.
The specialized heat-shrink manufacturing process permanently interlocks the outer ring and carrier for a secure, precise fit. MOTO-MASTER’s design can outlast an aluminum sprocket by up to three times, helping provide extended service life during demanding riding conditions. The carrier is color-anodized in black for added surface durability and a clean, factory-inspired appearance.
Each MOTO-MASTER Fusion Series sprocket is CAD designed, CNC machined, and laser cut using advanced manufacturing technology. The accurately produced tooth profile supports consistent chain engagement, while the lightweight aluminum carrier helps reduce unsprung and rotating mass compared with a standard steel sprocket. This 47-tooth configuration is a practical replacement or gearing option for compatible GasGas, Husqvarna, and KTM motorcycles. Verify fitment, chain size, and final-drive specifications before installation.
