This reduces rotational mass by 50% for improved handling and acceleration. Precisely engineered and manufactured in the Netherlands, it offers a perfect fit and optimal chain engagement. Compatible with Husqvarna TC 85 (2014-2022) and KTM SX 105/85 (2004-2021). Elevate your motorcycle´s transmission performance with the MOTO-MASTER 428 Husqvarna/KTM 620083449 Aluminium Rear Sprocket. This isn´t just a replacement part, it´s a significant upgrade designed for riders who demand the ultimate combination of durability and lightweight performance. Engineered for the rigorous demands of motocross, this sprocket represents the pinnacle of transmission technology, offering a clear advantage on the track and trail.The core of this product is the innovative Fusion Dual Rear Sprocket design. This advanced concept masterfully solves the classic dilemma of choosing between a lightweight aluminium sprocket and a durable steel one. By combining the best properties of both materials, MOTO-MASTER delivers a sprocket that offers unparalleled performance without compromise. The outer ring, the part that endures the constant friction and force from the chain, is constructed from a special hardened and nickel-coated steel. This results in exceptional longevity, allowing the sprocket to will outlast an aluminium sprocket up to 3 times. This incredible durability translates to fewer replacements, lower long-term costs, and increased reliability during critical races.While its durability is comparable to steel, its weight is not. This Fusion sprocket achieves a remarkable 50% less weight compared to a normal steel sprocket. This massive reduction in rotating mass is made possible by its aircraft-grade 7075-T6 aluminium inner carrier. Reducing unsprung weight is one of the most effective ways to enhance your bike´s handling and acceleration. You´ll notice a more responsive throttle, quicker acceleration out of corners, and improved suspension action, as the wheel can follow the terrain more effectively.The true genius lies in how these two distinct materials are joined. The precise manufactured outer ring and carrier interlock permanently using a specialized heat-shrink procedure. This high-tech process ensures a solid, seamless, and incredibly strong bond that will not fail under stress. To further enhance its resilience and provide a factory-race look, the carrier is colour anodized coated for extra durability against the elements.Every MOTO-MASTER sprocket is a testament to precision engineering. It is CAD designed, CNC machined and laser cut using state of the art technology, guaranteeing a perfect fit and optimal chain engagement. This meticulous manufacturing process, engineered and manufactured in the Netherlands, ensures the highest standards of quality and performance, giving you the confidence to push your machine to its limits.Compatible models:HUSQVARNA TC 85 17/14 2014-2022.HUSQVARNA TC 85 19/16 2014-2022.KTM SX 105 2004-2011.KTM SX 85 17/14 2004-2021.KTM SX 85 19/16 2004-2021. tradeinn Motardinn
