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.
THE NEW SOHC ENGINE IS 23 MM SHORTER, 23 MM NARROWER AND 9 MM LOWER THAN THE PREVIOUS GENERATION. EVERY INTERNAL COMPONENT WAS REVISED AND REPOSITIONED, LOWERING WEIGHT BY AN ASTONISHING 1.8 KG FOR AN OVERALL WEIGHT OF 27.8KG, INCREASING POWER TO 63 HP AND IMPROVING TORQUE ALONG THE ENTIRE REV-RANGE. MASS-CENTRALISATION WAS A KEY DEVELOPMENT FACTOR, ENABLING CHASSIS ENGINEERS TO POSITION THE ENGINE CLOSER TO THE CENTRE OF GRAVITY FOR GREATLY IMPROVED HANDLING AND MANOEUVRABILITY. VIBRATIONS ARE KEPT TO A MINIMUM THANKS TO A MULTIFUNCTIONAL COUNTER BALANCE SHAFT THAT ALSO DRIVES THE WATER PUMP AND TIMING CHAIN.
