KTM introduced a heavily revised 450 SX-F model last year. Some of the major updates were a more compact cylinder head, a frame that had a 2-percent increase in longitudinal stiffness and a 10-percent increase in torsional stiffness, and new suspension settings to match with the more rigid chassis. Compared to its predecessor, the engine was less responsive off the bottom, and the suspension and chassis changes made for a less comfortable ride. KTM listened to the feedback from the media and its customers, and went to work to refine it for MY20. We rode the 2020 KTM 450 SX-F at Fox Raceway in Pala, California, for the first time to see how the changes the Austrian manufacturer made to its flagship motocross bike felt on the track.
