Moto-Master Fusion Series Dual Ring Rear Sprocket 49-Tooth Orange for Gas Gas, Husqvarna and KTM (620273549)

Upgrade your motorcycle’s drivetrain with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, part number 620273549. Designed for compatible Gas Gas, Husqvarna and KTM applications, this 49-tooth rear sprocket combines a hardened, nickel-coated steel outer ring with a lightweight aircraft-grade 7075-T6 aluminum carrier. The dual-ring construction provides the durability needed for demanding riding while reducing weight compared with a conventional steel sprocket.
The specialized heat-shrink manufacturing process permanently interlocks the outer ring and carrier for a secure, precise assembly. The steel outer ring is engineered to outlast an aluminum sprocket by up to three times, helping provide extended service life under high-load conditions. The aluminum carrier delivers a significant weight reduction compared with a standard steel design, supporting responsive handling and efficient drivetrain performance.
The carrier features a durable color-anodized orange finish for added protection and a distinctive appearance. MOTO-MASTER uses CAD design, CNC machining and laser-cutting technology to produce accurate components with consistent fit and finish. This Fusion Series rear sprocket is a practical performance upgrade for riders seeking a lightweight, durable and precisely manufactured replacement for compatible Gas Gas, Husqvarna and KTM motorcycles.
