Just as expected, all of the changes first debuted on the 2018 KTM 450 SX-F Factory Edition have been carried over into the production model of the 2019 KTM 450 SX-F. The Austrian brand has revamped the big-bore offering with a new chassis, updated engine with new internal components, and revised suspension settings that will make the 450 class even more competitive among the major OEMs. To learn more about the bike, we had KTM’s David O’Connor point out the new parts and explain the benefits.
