Moto-Master Fusion Series Dual Ring Rear Sprocket, 48-Tooth, Red (620123348)

Upgrade your motorcycle’s final-drive performance with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket. This 48-tooth rear sprocket combines a hardened, nickel-coated steel outer ring with an aircraft-grade 7075-T6 aluminum carrier to deliver an excellent balance of durability, strength, and reduced weight. Compared with a conventional steel sprocket, the Fusion design weighs approximately 50% less while the specialized outer ring is engineered to provide significantly longer service life than an aluminum sprocket.
The precision-manufactured outer ring and carrier are permanently interlocked using a specialized heat-shrink procedure, creating a secure, durable assembly designed for demanding riding conditions. The carrier features a red anodized finish that adds protection against wear while providing a clean, performance-oriented appearance. This dual-ring construction helps reduce rotating mass without sacrificing the wear resistance needed for reliable chain engagement.
MOTO-MASTER uses advanced CAD design, CNC machining, and laser-cutting technology to produce the Fusion Series Rear Sprocket with accurate fitment and consistent manufacturing quality. Part Number 620123348 is designed for riders seeking a lightweight, durable replacement sprocket for high-performance street, off-road, and competition applications. Verify vehicle compatibility and required tooth count before installation.
