The ground-breaking new generation chassis is fitted with the most powerful Husqvarna motocross engine ever developed. The 63 horsepower single-overhead-cam 450 cc power plant has been completely redesigned; it is now smaller and lighter and has been completely reconfigured for optimal mass-centralisation within the new chromoly steel frame. The new bodywork elevates the riding experience thanks to accurately developed ergonomics that focus on instilling rider confidence, complete control and reduced fatigue.
