Moto-Master Fusion Series Dual Ring Rear Sprocket, 52 Tooth, Blue, Yamaha (620093452)

Upgrade your Yamaha drivetrain with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, part number 620093452. Designed for riders who demand dependable performance and reduced rotating weight, this 52-tooth 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 chain contact occurs while maintaining a lighter overall design than a conventional steel sprocket.
The specialized heat-shrink manufacturing process permanently interlocks the precisely manufactured outer ring and carrier for a secure, integrated assembly. Compared with a standard aluminum sprocket, the hardened steel outer ring is designed to deliver up to three times the service life, helping reduce replacement frequency during demanding riding conditions. The carrier is color anodized in blue for added surface durability and a distinctive appearance that complements Yamaha motorcycles.
MOTO-MASTER uses CAD design, CNC machining, and laser-cutting technology to produce the Fusion Series sprocket with accurate fitment and consistent performance. The 52-tooth gearing configuration supports reliable chain engagement and can help tailor final-drive characteristics to suit your riding setup. Verify the application and gearing requirements for your Yamaha motorcycle before installation.
