Moto-Master Fusion Series Dual Ring Rear Sprocket, 49-Tooth, Black, Honda (620023249)

Upgrade your Honda motorcycle’s final-drive performance with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, Part 620023249. This 49-tooth rear sprocket combines a hardened, nickel-coated steel outer ring with a lightweight aircraft-grade 7075-T6 aluminum carrier to deliver an effective balance of durability, reduced weight, and precise power transfer. The black finish provides a clean appearance suited to performance-focused applications.
The specialized heat-shrink manufacturing process permanently interlocks the outer ring and carrier, creating a secure dual-ring assembly designed for demanding riding conditions. Compared with a conventional steel sprocket, the Fusion Series design weighs approximately 50% less while the hardened steel outer ring is engineered to provide service life of up to three times that of an aluminum sprocket. This construction helps reduce unsprung and rotating mass without sacrificing wear resistance at the chain-contact surface.
Each MOTO-MASTER 620023249 sprocket is CAD designed, CNC machined, and laser cut using advanced manufacturing technology for consistent fit and accuracy. The carrier is color anodized for added durability and corrosion resistance, while the precisely manufactured components support reliable chain engagement and long-term performance. Verify the 49-tooth configuration and Honda application before installation, and follow the motorcycle manufacturer’s service procedures for sprocket replacement and chain alignment.
