More means more — the pure two-stroke power of the quarter-liter engine turns the 250 SX into a precision tool with an unbeatable power-to-weight ratio. With the new linkage rear suspension and completely new frame, it now raises the bar even higher for 250cc machines. Never has it been easier to ride onto the podium with a two-stroke against bigger-bore four-strokes.
