Moto-Master Fusion Series Dual Ring Rear Sprocket 50 Tooth Black for TM (620193250)

Upgrade your TM motorcycle with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, engineered to deliver a strong balance of durability, reduced weight, and dependable drivetrain performance. This 50-tooth rear sprocket features a special hardened, nickel-coated steel outer ring designed to outlast a comparable aluminum sprocket by up to three times, helping provide long-lasting wear resistance in demanding riding conditions.
The Fusion Series design pairs the steel outer ring with an aircraft-grade 7075-T6 aluminum carrier, reducing weight by approximately 50% compared with a conventional steel sprocket. The outer ring and carrier are precisely manufactured and permanently interlocked using a specialized heat-shrink procedure, creating a secure dual-ring assembly that supports consistent power transfer and reliable service life.
The carrier is color-anodized in black for added durability and a clean, factory-inspired appearance. MOTO-MASTER uses CAD design, CNC machining, and laser-cutting technology to produce the 620193250 sprocket with precise fit and dependable manufacturing quality. Designed for compatible TM applications, this rear sprocket is a practical choice for riders seeking enhanced durability without the unnecessary weight of a standard steel design.
