450 SEF FACTORY 2026

Built to Dominate

The MY25 Sherco 450 SEF Factory combines the lightweight agility of a 300cc four-stroke with the robust power of a 450cc engine. This gentle giant is equally at home carving up single trails or charging through the desert in sixth gear, offering a smooth, responsive, and exceptionally capable ride. Its versatility, power, and refined performance make it an excellent choice for riders seeking a bike that can do it all.


Why Choose the Sherco 450 SEF Factory?

The MY26 450 SEF Factory is the ultimate expression of Sherco’s engineering prowess – a powerhouse 4-stroke that blends brute strength with razor-sharp agility.

Delivering explosive torque and top-end power, the 450 SEF Factory is built for riders who demand maximum performance in open terrain and high-speed racing. Despite its big-bore muscle, it remains remarkably agile and balanced, thanks to Sherco’s championship-winning chassis and KYB suspension setup. The bike inspires confidence across all conditions, offering stability and predictability through deep ruts, rocky climbs, and wide-open desert. Developed and tested at the highest levels of enduro racing, it’s a machine built to win – and built to last.

For riders who want it all – power, poise, and performance – the MY26 Sherco 450 SEF Factory is the definitive choice.
