Significant design work was done to improve the chassis, giving it a new personality. The work done by the Sherco engineers is a major step forward for current and future developments. The main feature is a new frame that is made entirely out of Chrome-Molybdenum steel that combines laminated steel tubes along with sheet metal plates that are all welded together to create the new frame. This configuration was selected after endurance and performance tests to prove its strength, flexibility and lightweight.
This new configuration includes repositioning the fuel tank, it is now in the forward position and the airbox is now in the center position. Therefore, the exhaust has been reviewed and redesigned in order to improve performance at low engine speeds and provide a smoother evacuation of the exhaust gas.
