Let's see the new KTM Sx 125 2025 together

It's only mid-April 2024, but KTM is already announcing its 2025 models , bringing innovation and excitement to the world of motocross with its new SX range.

The 2025 KTM 125 SX arrives on the market with a series of technological innovations that promise to revolutionize the on-track experience for motocross enthusiasts. Let's discover together the salient features of this exciting model.

The 2025 KTM 125 SX is equipped with a 2-stroke engine that, thanks to electronic fuel injection (EFI) – already in use since the 2024 models – guarantees constant power at any altitude, eliminating the need for manual carburetor adjustments before racing.
This system ensures immediate gas response and explosive power.
Will the problems arising from 2024 have improved?

Mass centralization is a key design concept for the 2025 KTM 125 SX, with special emphasis placed on optimizing weight distribution. This design philosophy focuses on positioning the bike's weight as close to the center of gravity as possible, resulting in a more direct response and agile handling . In practice, the engine has been designed to cluster rotating mass in a central point , thereby improving interaction with the chassis.

The result of this effort is a riding sensation that translates into greater lightness and agility, allowing the rider to maneuver the bike with greater ease and precision, especially in fast corners and sudden changes of direction.

The frame design has been optimised around the rear shock absorber, making it slimmer and featuring new engine mounts and strategically placed openings to improve frame flex.

These changes are not only aesthetic but also functional, having a positive impact on driving dynamics.

The front of the frame has also been revised with a different tube thickness compared to the previous year's model and new engine mounting points. This brings a double advantage: a weight saving of around 300 grams and greater flexibility of the frame to ensure optimal performance when cornering.
