Light and Nimble

Like all Sherco models, the 250 SE 2-stroke benefits from the latest technology and it is also equipped with an electric starter. The valve openings are electronically controlled and are a function of the ignition curve which provides perfect throttle response. This is the secret of this engine, it is unanimously recognized for its efficiency at both high and low speeds.

The chassis meanwhile received upgrades based on the recipe that has made the Sherco reputation: perfect handling and adaptation to the demands placed upon it by the rigors of enduro racing. The new swing arm improve traction, and the new designed wheel and hubs reduce maintenance and weight.
