Moto-Master Fusion Series Dual-Ring Rear Sprocket 52-Tooth Black for Yamaha (620093252)

Upgrade your Yamaha motorcycle’s drivetrain with the MOTO-MASTER Fusion Series Dual-Ring Rear Sprocket, Part 620093252. This premium rear sprocket combines a hardened, nickel-coated steel outer ring with an aircraft-grade 7075-T6 aluminum carrier to deliver a strong, lightweight solution for demanding riding conditions. The 52-tooth configuration supports precise chain engagement and dependable power transfer while maintaining the performance-focused design expected from MOTO-MASTER components.
The hardened and nickel-coated steel outer ring is engineered to outlast a comparable aluminum sprocket by up to three times, helping provide extended service life under frequent use. At the same time, the aluminum carrier reduces weight by 50% compared with a standard steel sprocket, helping minimize unsprung and rotating mass. The carrier is color-anodized for added durability and a distinctive black finish that complements a wide range of Yamaha applications.
MOTO-MASTER manufactures this Fusion Series sprocket using CAD design, CNC machining, and laser-cutting technology for consistent accuracy. The outer ring and carrier are precisely manufactured to interlock permanently through a specialized heat-shrink procedure, creating a secure dual-ring assembly designed for reliable performance. Built for riders seeking durability, reduced weight, and refined drivetrain function, this black rear sprocket is a practical performance upgrade for compatible Yamaha motorcycles.
