Moto-Master Fusion Series Dual Ring Rear Sprocket, 52 Tooth, Black (620123252)

Upgrade your motorcycle’s final drive with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, part number 620123252. Designed for demanding riding conditions, this 52-tooth rear sprocket combines a hardened, nickel-coated steel outer ring with a lightweight aircraft-grade 7075-T6 aluminum carrier. The dual-ring construction delivers the wear resistance of steel while reducing overall weight compared with a conventional steel sprocket.
The specialized heat-shrink manufacturing process permanently interlocks the outer ring and carrier for a precise, secure connection. This construction is engineered to help the sprocket maintain dependable chain engagement and long-term durability under repeated use. Compared with an aluminum sprocket, the hardened steel outer ring is designed to provide up to three times the service life, making it a practical choice for riders seeking a balance of performance, weight savings, and longevity.
The MOTO-MASTER Fusion Series sprocket features a color-anodized carrier for added surface durability and a black finish that complements a wide range of motorcycle styles. Each sprocket is CAD designed, CNC machined, and laser cut using advanced manufacturing technology to support accurate fitment and consistent performance. Select this MOTO-MASTER 52-tooth rear sprocket for a lightweight, durable replacement or performance upgrade to your motorcycle’s drivetrain.
