Description

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. It's time to extend the trophy room.
