After last year’s new generation of SX machine was launched with revolutionary WP AER 48 forks, a new chassis, plus new engines over previous models (except 250 SX), the KTM research and development departments in Austria and United States have been making further improvements for 2017, and updated the 250 SX model to the latest specification of chassis with a brand new engine.
With input from the KTM Motorsports department being influential to serial production, especially in the US where the factory team must race homologated machines and it can be noted Ryan Dungey has just won backtoback 450 Supercross World Championship titles aboard a KTM 450 SXF, the SX model lineup is better than ever.
