Moto-Master Fusion Series Dual Ring Rear Sprocket, 49-Tooth, Red (620123349)

Upgrade your motorcycle’s drivetrain with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, Part Number 620123349. Designed with a hardened, nickel-coated steel outer ring and an aircraft-grade 7075-T6 aluminum carrier, this 49-tooth sprocket combines long-lasting wear resistance with reduced rotating weight. The outer ring is engineered to outlast a comparable aluminum sprocket by up to three times while weighing approximately 50% less than a conventional steel sprocket.
The precision-manufactured outer ring and carrier interlock permanently through a specialized heat-shrink process, creating a secure and durable dual-ring assembly. This construction helps maintain dependable power transfer and consistent performance during demanding riding conditions. The carrier is color-anodized in red for added surface durability and a distinctive appearance that complements a wide range of motorcycle builds.
MOTO-MASTER uses CAD design, CNC machining, and laser-cutting technology to produce the Fusion Series sprocket with accurate fit and reliable quality. The 49-tooth configuration is suited for riders seeking a performance-focused replacement or gearing adjustment, subject to motorcycle compatibility. Verify the required tooth count, fitment, and chain specifications before installation.
