Get ready to experience what it feels like to be a marble launched from a slingshot. The KTM 150 SX pulls hard from the bottom, gallops in the middle, and sings at the top. Which is where it belongs.


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. 

Selectable Maps

The 2025 KTM 150 SX features a map selecting switch allowing the racer to switch between 2 engine maps. The White Map (Map 1) provides linear, predictable power delivery ideally suited to attach hard-packed dirt with a leaner air-fuel mixture. Alternatively, the Green Map (Map 2) is tuned for loose, thick sandy conditions with a richer mix.

EFI + Power Valve

With EFI comes great rideability. Along with electronic fuel injection is an electronic 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!


Upgraded tank shrouds using bi-compound plastics channel air towards the radiators more effectively, while a new fuel tank roll, makes for a tighter, more secure fitment, reducing the chance of frame scrubbing and dramatically improving durability. All this works alongside the specially-developed rider triangle, to provide unmatched knee contact and gripping surfaces - especially when standing on the pegs.
