2026 Sherco ST Factory 250cc Trials Bike

The 2026 Sherco ST Factory 250 is the ultimate balance between power, control and precision. Sitting at the heart of the Factory range, the 250 delivers stronger torque than the 125 while maintaining the smooth, manageable character that modern trials demands.

Designed for serious club riders, national competitors and experienced trials riders, the ST Factory 250 offers confident drive, predictable response and the ability to tackle today’s biggest sections without sacrificing feel.

What’s New for 2026

Sherco have introduced significant refinements to enhance smoothness, reliability and throttle control:

• New graphics kit
• New engine mapping designed to smooth engine behaviour
• New electronic injection system
• Injection wake-up button to facilitate starting
• New BIG FLOW fuel pump
• New crankshaft
• New piston pin
• New wiring harness
• New longer gear ratio (400 D FIM TR rear sprocket & 101-link chain)
• New fuel hose for easier disassembly
• OXIA handlebars
• New brake pedal axle

The updated mapping and injection system create a more progressive power delivery, improving traction in technical sections while maintaining the strength needed for modern obstacles.

Engine & Performance

The 249cc 2-stroke engine provides a fuller torque curve and stronger drive than the 125, without the aggressive hit of a 300. It’s the ideal capacity for riders who want versatility across all terrain.

Electronic fuel injection ensures consistent fuelling in varying conditions, while the revised internal components improve engine feel and durability.

The new longer gear ratio enhances control in technical sections and aligns the bike with FIM competition requirements.

Factory-Level Chassis & Suspension

The chrome-moly tubular chassis remains the foundation of Sherco’s precision handling, delivering excellent feedback and stability.

Suspension is handled by:

• Aluminium Tech Ø39mm front fork
• Reiger 2-way rear shock
• Progressive linkage rear suspension
• With 165mm of suspension travel front and rear, the 250 remains composed over big steps, loose terrain and tight technical sections.
• Lightweight Morad aluminium rims and powerful hydraulic braking complete the Factory race package.
