Moto-Master Fusion Dual Ring Rear Sprocket Pitch Sprockets

The Moto-Master Fusion Dual-Ring Rear Sprocket combines a hardened steel outer ring with a lightweight aluminum carrier. It is a durable, lightweight rear drive sprocket for off-road, motocross and other powersports use. Moto-Master designs and builds the Fusion line in the Netherlands.

Key Features:

• Special hardened, nickel-coated steel outer ring for wear resistance
• Lasts up to 3 times longer than a standard aluminum sprocket
• Up to 50% lighter than a conventional steel sprocket
• Aircraft-grade 7075-T6 aluminum carrier
• The outer ring and carrier are joined permanently with a specialized heat-shrink process
• Color-anodized carrier for added durability
• CAD designed, CNC machined and laser cut to tight tolerances

The dual-ring design keeps the long wear life of steel teeth and cuts rotating mass with an aluminum center. That gives riders a good balance of weight savings and service life. Choose the child option that matches your chain size, tooth count and mounting pattern.
