350 SX-F Video

Stefan Everts, world motocross champion with 14 victories in 15 Grand Prix, set out as the KTM Race Director to design a better MX bike.

Everts had a vision where the future of motocross was heading and in KTM he found an ideal partner for his vision: efficient and maximum practicable performance from smaller displacements in an overall package that’s tailored unconditionally to the requirements of the rider.

After 4 years in the making, it’s ready: the new 2011 KTM 350 SX-F. With a new engine, fuel injection system and smaller displacement, new bodywork, new chassis – in fact, a whole new concept.

What with the first Grand Prix victory and racing to the top of the overall standings in the MX1 class after only two races, maybe even the beginning of a new era in motocross.
