Moto-Master Fusion Series Dual Ring Rear Sprocket, 48-Tooth Blue, TM (620193448)

Upgrade your motorcycle’s final-drive system with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, part number 620193448. Designed for riders who demand durability without unnecessary weight, this rear sprocket combines a hardened, nickel-coated steel outer ring with an aircraft-grade 7075-T6 aluminum carrier. The result is a high-performance sprocket engineered to deliver long service life and dependable operation in demanding riding conditions.
The hardened steel outer ring is designed to outlast a comparable aluminum sprocket by up to three times while helping reduce weight by approximately 50 percent compared with a conventional steel sprocket. Its precisely manufactured outer ring and carrier interlock permanently through a specialized heat-shrink process, creating a secure dual-ring assembly that supports consistent power transfer and reliable chain engagement.
MOTO-MASTER uses CAD design, CNC machining, and laser-cutting technology to produce the Fusion Series sprocket with accurate fit and finish. The aluminum carrier features a durable blue anodized coating that adds corrosion resistance and a distinctive appearance. With its 48-tooth configuration and application-specific fit for TM motorcycles, this MOTO-MASTER sprocket is a practical performance upgrade for riders seeking a strong, lightweight, and precisely engineered replacement component.
