Sherco ST 2017 250cc
Robust with great handling
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.
The adjustments that have been made to the size of the available engines has allowed the character of the range to be refined. The 300 is the weapon of choice for competitors and experienced riders, who want a demanding and powerful motorcycle. The 250 meanwhile is reserved for intermediate riders who are looking for a certain sweetness in acceleration and an easier bike to ride.
