Moto-Master Fusion Series Dual Ring Rear Sprocket, 49-Tooth, Black, Kawasaki/Suzuki (620063249)

Upgrade your motorcycle’s final-drive performance with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, part number 620063249. Designed for compatible Kawasaki and Suzuki 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 helps deliver the durability needed for demanding riding while reducing overall weight compared with a conventional steel sprocket.
The specialized heat-shrink manufacturing process permanently interlocks the precision-manufactured outer ring and carrier, creating a secure, rigid assembly designed for long-term reliability. The hardened nickel-coated steel ring is engineered to outlast an aluminum sprocket by up to three times, helping resist wear during repeated use. Its lightweight design weighs approximately 10.6 ounces, offering up to 50% less weight than a standard steel sprocket without sacrificing strength where it matters most.
MOTO-MASTER manufactures the Fusion Series sprocket using CAD design, CNC machining, and laser-cutting technology for consistent precision and dependable fitment. The aluminum carrier features a color-anodized coating that adds durability and helps maintain its black finish. Built for riders seeking a balance of reduced rotating mass, extended service life, and premium construction, the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket is a performance-focused replacement for select Kawasaki and Suzuki motorcycles.
