2026 SHERCO SEF FACTORY 300 4-STROKE

THE BEST ENDURO BIKE IN THE MARKET.

Sherco dirt bikes are highly regarded, particularly in the enduro and trials markets, for their exceptional handling in technical terrain, premium stock components, and versatile, high-torque engines. Sherco is known for equipping their “Factory” models with top-tier components straight from the factory, which often saves owners from purchasing upgrades. The 2026 Sherco dirt bike lineup features refreshed, all-blue styling and updated graphics. The 300 SEF Factory is a high-performance model featuring KYB closed-cartridge suspension, Brembo brakes, and map switches for power delivery adjustment. The 250, 450, and 500 SEF Factory models retain full Akrapovič exhaust systems, while the 300 SEF switches to an SPES header pipe with an Akrapovič muffler.

HIGHLIGHTS:
• New 2026 graphics kit
• Blue plastic kit
• New Galfer rear brake disc: optimized braking performance and weight reduction
• New Nilos seal at the bottom of the steering stem: reduced friction, improved sealing, and better protection against mud
• Full Akrapovic exhaust system
