KTM 450 SX-F 2023

We aren’t ones to brag, but with a trophy cabinet ready to rip at the seams, the KTM 450 SX-F is the epitome of a podium hunter. With 5 AMA 450 supercross titles in the last 7 seasons, the 2023 KTM 450 SX-F rolls into the paddock already armed with the learnings of past championships – and an all-new arsenal of weaponry.

With a peak power output of 63bhp, and an overall engine weight of only 26.8kg, you’ll leave the competition with more than a little mud on the face.
