Moto-Master Fusion Series Dual Ring Rear Sprocket 52-Tooth Blue for TM (620193452)

Upgrade your TM motorcycle with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, Part 620193452. Designed for demanding off-road and racing applications, this 52-tooth rear sprocket combines a hardened, nickel-coated steel outer ring with an aircraft-grade 7075-T6 aluminum carrier. The dual-ring construction delivers a strong balance of durability, reduced weight, and dependable drivetrain performance.
The specialized heat-shrink manufacturing process permanently interlocks the outer ring and carrier for a secure, precise fit. Compared with a conventional steel sprocket, the Fusion Series design reduces weight by 50 percent while the hardened steel outer ring is engineered to provide up to three times the service life of an aluminum sprocket. This makes it a practical choice for riders who want long-lasting performance without unnecessary rotational mass.
MOTO-MASTER uses CAD design, CNC machining, and laser-cut manufacturing technology to produce the Fusion Series Rear Sprocket with consistent accuracy. The carrier is finished with a blue color anodized coating that adds durability and maintains a clean, distinctive appearance. Built specifically for compatible TM applications, this rear sprocket is a performance-focused replacement for riders seeking reliable power transfer, precise fitment, and extended component life.
