This is the measure of all motocross World Championship bikes with a genuine factory engine! There has never before been a bike like this for sale. Feather light and with any amount of power, the KTM 125 SX leaves ample room to correct the line and is always easy to control. With its redesigned chassis setup, new V-Force 3 membrane and a broad range of revolutions, it makes other 125 cc 2-strokes look old. And it’s only KTM that supplies high quality series details like the adjustable CNC-machined triple clamp.
