Massive horsepower: The sheer power of the quarter-liter two-stroke engine makes the 250 SX a precision instrument with an unbeatable power-to-weight ratio. The new progressive suspension and the completely new frame allow it to set the bar even higher in the 250 cc. Never has it been easier to reach the podium in the MX1 category with a two-stroke.
New intake pipe
The flow-optimized intake flange of the 250 SX, between the airbox and the carburetor, now ensures even better engine breathing. The water-cooled two-stroke engine thus revs even better and offers more power over the entire range of revs..
Adjustable exhaust control and adjustable ignition curve
The choice of two connector ignition curves and the adjustable TVC exhaust control allow the 250 SX rider to tailor the character of the two-stroke engine to his personal needs..
Engine power and weight
The relatively simple technique of the two-stroke engine has undeniable advantages, one of which is undoubtedly its high power per liter and low weight. That \ ‘s why the 250 SX is virtually unbeatable when it comes to power-to-weight ratio. Unbeatable performance and extraordinary handling are the strength of its character.
New frame
Completely redesigned, the frame of the 250 SX, made of high-quality chromium-molybdenum steel, is not only extremely light and resistant to torsion. It is also distinguished by its particularly balanced geometry which combines childlike handling and formidable precision..
New Linkage rear suspension.
Now even KTM’s MX program two-stroke comes equipped with the complex link-link rear suspension. The articulation of the shock absorber by means of a connecting rod system provides great progressiveness as well as a wide adjustment range. The 250 SX is thus subscribed to the podium, even on the most brutal Motocross tracks..
New swing arm
The new Linkage rear suspension is mated to the new cast aluminum swingarm, designed for optimum resistance to lateral torsion and perfectly defined longitudinal flexibility. The 250 SX owes a great deal to him for its great in-line stability, extraordinary handling and extreme traction..
New setting of the telescopic fork
The inverted telescopic fork has been further improved, featuring closed cartridge technology and a little tighter adjustment for even less bottoming out. The WP fork with its 48 mm (1.89 in) tubes thus contributes significantly to the extraordinary handling of the 250 SX..
Bodywork
The skin of the 250 SX with the slim lines of the saddle and the spoiler and its excellent contact points further perfects its ergonomics and makes it even easier and more precise to ride..
