Moto-Master Fusion Series Dual Ring Rear Sprocket 49-Tooth Black TM (620193249)

Upgrade your motorcycle’s drivetrain with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, part number 620193249. Designed for demanding off-road and performance applications, this rear sprocket combines a hardened, nickel-coated steel outer ring with a lightweight aircraft-grade 7075-T6 aluminum carrier. The result is a durable, responsive sprocket assembly engineered to deliver long service life without the added weight of a conventional steel sprocket.
The specialized heat-shrink manufacturing process permanently interlocks the precisely manufactured outer ring and carrier, creating a secure, rigid connection designed to withstand repeated impact and drivetrain loads. Compared with a standard aluminum sprocket, the hardened outer ring can provide up to three times the service life, while the overall construction weighs approximately 50% less than a comparable steel sprocket. The black color-anodized carrier adds an extra layer of durability and maintains a clean appearance through demanding riding conditions.
MOTO-MASTER uses CAD design, CNC machining, and laser-cutting technology to produce the Fusion Series sprocket with consistent accuracy and dependable fitment. This 49-tooth rear sprocket is a practical choice for riders seeking a balance of durability, reduced rotating mass, and high-quality manufacturing for motocross, trail, and other performance-oriented applications. Verify motorcycle fitment before installation.
