Factory engine kit

KTM is renowned for the high performance level of the 250 SX-F engine. Another highlight for KTM was the 2008 GP season, which was clearly dominated by the orange machines made in Austria winning the MX2 world championship with Tyla Rattray.
Apart from the KTM factory pilots Rattray and Searle, many other riders were able to finish in the top 10 or even jump onto the podium using KTM SXS bikes. For 2009, the level of the bikes can be raised even further with availability of the KTM Factory-SXS-Kit. Improved performance, higher engine speeds and optimum reliability guarantee top results for the 2009 race season as well. Components
