The world champion concept

There can be no better proof of the supremacy of the 250 SX-F than three consecutive MX2 world championship titles. But that’s no reason for KTM to rest on its laurels. The new model is now available with a revamped chassis and an electric starter that proves its worth in many situations. Hence the smallest four-stroke in the KTM MX range continues to guarantee top finishes.

New for 2012 the 250 SX-F model is now equipped with Dunlop MX51 tires.


The compact, state-of-the-art DOHC four-stroke engine in the 250 SX-F is equipped as standard with an electric starter for the 2012 model year. Derived directly from the Marvin Musquin's world championship bike, it excels with an extremely wide usable rev range and powerful performance from the bottom end up to beyond the nominal engine speed.

Valve train

In the cylinder head with two overhead camshafts, extremely lightweight, carbon-coated cam levers actuate four titanium valves. This elaborate valve train and ultra-light piston on the 250 SX-F allow the extremely short-stroke engine to rev up to 13,400 rpm.

Engine management (EMS)

The Keihin engine management system with electronic fuel injection ensures spontaneous responsiveness and maximum performance from the engine. Various engine characteristics can be activated with an optional map select switch.


The state-of-the-art frame on the 250 SX-F made from high-quality chrome-molybdenum steel is extremely light and torsion-resistant. It is also characterized by a particularly balanced geometry that combines playful handling with razor-sharp precision.
