Engine & Performance
At the heart of the 2026 ST Factory 125 is a refined 123.7cc 2-stroke engine featuring electronic fuel injection for precise throttle response and consistent performance in all conditions.
The updated mapping smooths the engine behaviour, making the bike easier to control in technical sections while still delivering the punch needed for bigger steps and obstacles.
Paired with Sherco’s lightweight chassis and premium Reiger suspension, the 125 feels incredibly agile — perfect for riders developing technique and precision.
Factory-Level Chassis & Suspension
The chrome-moly tubular frame delivers the rigidity and feel Sherco is known for, while the Tech aluminium front forks and Reiger 2-way rear shock ensure exceptional traction and control.
With 165mm of suspension travel front and rear, the ST Factory 125 absorbs impacts smoothly and maintains stability on the most technical terrain.
Lightweight Morad aluminium rims and high-performance hydraulic braking complete a race-ready package.
