The MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, part number 620273250, is engineered for high-performance off-road and motocross applications. Crafted from aircraft-grade 7075-T6 aluminum, this sprocket offers exceptional durability and lightweight performance, reducing weight by approximately 50% compared to standard steel sprockets. The outer ring is made from special hardened, nickel-coated steel, which significantly extends its lifespan—up to three times longer than traditional aluminum sprockets. Its precise manufacturing process includes CAD design, CNC machining, and laser cutting, ensuring accurate fit and smooth operation. The outer ring and the aluminum carrier are permanently interlocked through a specialized heat-shrink process, providing a reliable and secure connection. The carrier features a color anodized finish for enhanced durability and corrosion resistance, maintaining its appearance despite rigorous use.
