SHERCO 250 SE FACTORY
Light and Nimble
Like all Sherco models, the 250 SE 2-stroke benefits from the latest technology and the power 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.
It is a high-performance, race-bred 2-stroke enduro motorcycle built for riders who demand precision, raw torque, and top-tier components straight out of the crate. Designed to conquer tight single-tracks, steep hillclimbs, and gnarly hard-enduro obstacles, this machine delivers tractor-like bottom-end grunt paired with razor-sharp handling but at same time less tiresome on the rider . This unsurpassed smooth power is delivered with perfect progression, guaranteeing maximum adhesion, synonymous with efficiency at the foot of the steepest slopes. The weight of the bike is very light considering the fact that it is equipped with a modern electric starting system.
Sherco has further improved the bike this year so that it is even more suited to performing well in the extreme enduro events. The new clutch is even more durable and the gearbox has been strengthened and shifting ease much improved. In the “soft” position, the new ignition settings and valve functions make extreme maneuvers manageable for every rider, no matter what their skill level is.
The chassis meanwhile received upgrades over last 3 years 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.
