Moto-Master Fusion Series Dual Ring Rear Sprocket, 50-Tooth, Blue (620123450)

Upgrade your motorcycle’s drivetrain with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, part number 620123450. Designed for riders who demand reduced weight and dependable durability, this 50-tooth rear sprocket combines a hardened, nickel-coated steel outer ring with an aircraft-grade 7075-T6 aluminum carrier. The two-material construction delivers the wear resistance needed for demanding riding while helping reduce rotating mass compared with a conventional steel sprocket.
The specialized heat-shrink manufacturing process permanently interlocks the precision-produced outer ring and carrier for a secure, accurately aligned assembly. MOTO-MASTER engineers use CAD design, CNC machining, and laser cutting to produce a precise component with consistent fit and finish. The hardened nickel-coated outer ring is engineered to outlast an aluminum sprocket by up to three times, providing a practical balance of long service life and lightweight performance.
The carrier features a blue anodized finish that adds durability and gives the sprocket a clean, distinctive appearance. With approximately 50% less weight than a standard steel sprocket, this MOTO-MASTER Fusion Series rear sprocket can help support responsive acceleration and handling while maintaining the strength required for regular performance use. Confirm fitment, tooth count, and drivetrain specifications for your motorcycle before installation.
