Specifications
Deliberately robust. The popular powerful and light two-stroke will have you right up front in the MX1 with just a turn of the hand. And all that using easily understood technology and simple maintenance. With its new frame, new PDS geometry, a new suspensions and completely new plastics, the 250 SX remains a serious challenger for the four-strokes.
