With the new generation of the 350 SX-F the success story can go on. The dominance with which this machine has won one world championship title after the other is unparalleled. In his first year as KTM factory rider, Antonio “Tony” Cairoli already managed to win the 2010 MX1 World Championship with just 350cc. Ever since, the Red Bull athlete from Sicily dominated the competition in his class at will. The results are five consecutive World Championship titles, won with ease in the top tier of MXGP by Cairoli and the KTM 350 SX-F. Almost as much power as a 450, but the agility of a 250—the basic idea is easily summarized. A concept that has been successful from the start.

For 2016 everything is new: chassis, suspension, bodywork and a more powerful fuel injected engine. The all-new 350 SX-F is even faster also due to an overall weight reduction of 6.8 pounds. An essential point in the new construction was to create even more compact dimensions in order to achieve a more effective centralization of mass for improved rideability.

This combination of low weight, playful agility and a high-revving engine will be again the right machine for Cairoli to defend his title in the new season, since the 350 SX-F provides the ideal characteristics for pros and amateurs alike.

The 250 SX-F was once again the world champion in MX2 for 2014 and added a prestigious 2015 AMA Supercross 250SX Championship to its amazing trophy cabinet. The 2014 season was a great success in racing at all levels around the globe, and the remainder of 2015 promises to be no different. Already known for its strong performance, the new generation 250 SX-F presents itself with a newly developed, stronger engine built into an all new chassis. The combination of a powerful engine in a lightweight and agile chassis is sure to make the 250 SX-F the star of the show for the future. The new 250 SX-F, the lightest and best performing bike in its class, is the right choice for both the amateur and professional rider; a winning bike that the competition will find hard to follow.

The engine of the 125 SX has been known to be the most powerful and most competitive engine of the class. But it was time to give a new push to the segment and set a clear statement, that the two-stroke technology is going to have a successful future due to its outstanding power-to-weight ratio, low cost and simplicity. The newly developed 125cc engine for 2016 features a completely new architecture with the latest KTM engineering know-how and the most advanced technology in the class. The result is that it produces better power all over the rev range while being more compact and 4.4 pounds lighter. 

Combine the all-new engine with the new state-of-the-art chassis that is shared with the 4-Stroke SX-F line, and you have a better handling 125 SX that will set a new benchmark in the class.
