No absolute beginners are to be found pootling around among the ranks of ambitious, young MX riders any more. This is where future champions fight for victory and the best chance for a place on the podium is on the 85 SX - as demonstrated convincingly by Henry Jacobi's 2010 world championship title. The 85 SX masters the toughest MX tracks with unperturbed ease. The grown-up KTM mini-crosser combines fully-fledged MX technology with perfect controllability.
