FIRST LOOK! KTM’S FULL-SIZE TWO-STROKE MOTOCROSS LINE UP INCLUDES THE 125SX, 250 SX & 300SX

The settings and configuration of the full-size KTM SX two-strokes come from the substantial success and learning in  competition The latest model lineup with a revitalized orange aesthetic and graphics now also embraces a shade of purple on the tank spoilers and fork guards.  Every model is equipped with class-leading electronics, refined chassis dynamics, and explosive power delivery. On the two-stroke SX models, the wiring harness routing has been improved, with updated fixing points and better organization for increased resistance to the elements.

KTM is the fourth year of the current generation for the KTM full-size models, the third year for the KTM 50 SX and 65SX, and the second for the KTM 85SX. The bikes keep moving from strength to strength as KTM find measures and changes to make sure we stay at the forefront of choice for all racers. The whole range has been restyled, but we’ve also found ways to bolster the KTM machines  because we know the components, the performance, and the technical base of these special KTMs. We support a broad line of off-road, cross-country and motocross two-strokes.
