When you have a bike in your range like the 250 SX-F, which has been the dominant force in the World Championship MX2 class for years, then it would be very easy to just sit back and carry on as before. Luckily, however, that's not how things work in racing, or at KTM for that matter. That's why the new 2011 generation is being launched with a completely reworked chassis, new bodywork and the next stage in engine development with fuel injection.
