Fusion Series Dual Ring Rear Sprocket (Black, 420-48T) Husqvarna, KTM

For over 20 years Moto-Master has specialized in the production of braking and transmission components for the off-road world and has been recognized by the market for their excellent quality and precision of construction.

The Moto-Master Fusion Dual-Ring Rear sprocket brings you the best of both worlds: special hardened and nickel coated steel outer ring and aircraft-grade 7075-T6 aluminum inner ring. These sprockets will outlast an aluminum sprocket up to 3 times with up to 50% less weight compared to a normal steel sprocket.

The Fusion sprockets are CNC machined to the tightest possible tolerances out of the best material available for racing sprockets. The precise manufactured outer ring and carrier are interlocked permanently using a specialized heat-shrink procedure, while the carrier has a color-anodized coated for extra durability.
