125 SX

Make: KTM

Model: 125 SX

Year: 2012


No absolute beginners are to be found putting around among the ranks of ambitious, young MX riders anymore. 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 ease. The grown-up KTM mini-crosser combines full-fledged MX technology with perfect controllability.
