Moto-Master Fusion Series Dual Ring Rear Sprocket 46-Tooth Orange for GasGas, Husqvarna and KTM (620273546)

Upgrade your motorcycle’s drivetrain with the MOTO-MASTER Fusion Series Dual Ring Rear Sprocket, part number 620273546. Designed for select GasGas, Husqvarna and KTM applications, this 46-tooth rear sprocket combines a hardened, nickel-coated steel outer ring with an aircraft-grade 7075-T6 aluminum carrier. The result is a durable, lightweight sprocket assembly engineered for demanding riding conditions and dependable long-term performance.
The specialized heat-shrink manufacturing process permanently interlocks the outer ring and carrier for a secure, precise connection. Compared with a conventional steel sprocket, the MOTO-MASTER Fusion Series design reduces weight by 50 percent while delivering an outer ring that can last up to three times longer than an aluminum sprocket. This combination helps reduce unsprung weight and supports responsive drivetrain performance without sacrificing durability.
The orange anodized carrier adds an additional layer of protection against wear while providing a distinctive appearance. Every sprocket is CAD designed, CNC machined and laser cut using advanced manufacturing technology to achieve accurate fitment, consistent tooth geometry and reliable chain engagement. The MOTO-MASTER 620273546 is a practical choice for riders seeking a high-performance rear sprocket built for strength, reduced weight and lasting service.
