2010 KTM 250 XC, If you want understandable and low-cost technology, this super-powerful and lightweight two-stroke is the perfect choice for the E2 class. The engine characteristic has been tuned for enduro use only. The choice between two ignition curves, plus a new crankshaft and modified casing delivers better power reserves in all speed ranges. The completely new frame with new PDS geometry, the improved suspension and new bodywork overall make the speedy 250 XC a serious challenger for the four-strokes. And since the casing and ignition rotor are already prepped for it, there⿿s nothing standing in the way of an E-starter upgrade.
