2011 KTM 350 SX-F

(discontinued)

In 2006, Stefan Everts was reigning world champion (with a mere 14 victories in 15 Grand Prix) and then he became KTM Race Director. Back then, he could already see 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. 4 years or so later, it's ready: the new 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 ...
