The new KTM 250 SX with its all-new engine has one of the best power-to-weight ratios in the world of dirt, forming the ultimate fist against more complex 4-stroke rivals. With the grunt to devour all sorts of tracks and terrains, and a lightweight chassis keen to skim the surface, this lovechild of KTM’s R&D and Motorsport departments is born to lead the next pack of winners into a hazy blue future.
