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 …

KTM won a lot of motocross races in 2010 with the 350 SX-F and it’s looking to translate that success to enduro racing in 2011. The EXC-F uses the exact same fuel-injected, DOHC, 349.7cc single-cylinder engine, which KTM claims is as powerful as a 450 and as light and compact as a 250.
