Picture this; You're 7 laps into an absolute ripper of a race. You miss your line and end up stalling in a deep rut. But you don't sweat it. All you do is press the starter button and you blast off again to take the final flag. This is the reality on the 2025 KTM 150 SX. Thanks to a 12,8V 2 Ah lithium ion battery is placed under the rider's seat, a high-quality stator & pickup and super robust design, the only thing you'll be kicking - is ass.

With EFI comes great rideability. Along with the electronic fuel injection and a power valve on the KTM 150 SX, allowing for more usable power throughout the rev range. Smoother power means better traction. Better traction means holeshot heaven!
Many parts of the 150 SX engine have been rearranged, modified, or developed from the ground up. With an overall weight of just below 18 kg, this is a powerhouse bar none. Designed to provide more torque than its stablemate, the KTM 125 SX, it remains true to its nature, without losing its typical high-revving lightweight 2-stroke character.

The fork also boasts new settings, which not only compliment the updated frame and rear linkage, but ensures stellar p

While we're on the topic, smaller diameter linkage bolts save weight, while new linkage seals refine rear shock response and advanced damping characteristics.
Besides the expertly crafted, hydro-formed, laser-cut, and robot-welded frame being engineered to provide exceptional rider feedback and straight-line stability, it consists of specifically calculated parameters of longitudinal and torsional flex. This means the frame acts as a "shock absorber" of sorts, making for a less harsh ride, resulting in less rider fatigue over many hard laps.
Get ready for a full-on berm assault. The 2025 KTM SX and SX-F machines have received major frame updates directly from Factory Racing efforts.
