The KTM 450 SX-F nearly won Dirt Rider's 450 MX Shootout last year, finishing in the runner-up spot with its strong but usable powerband, good suspension, and nimble handling. For 2019, KTM made several changes to the engine, suspension, and chassis, similar to those found on last year's Factory Edition model. The stiffer frame, updated suspension settings, narrower chassis, and more agreeable ergonomics were all improvements, but mellow bottom-end power delivery made the bike feel heavy on the track, despite its being the lightest bike in the test at 234 pounds. The 2019 450 SX-F is an improvement over last year's model in most areas, but the bottom-end power left something to be desired. Combine that with the fact that the other bikes have also continued to improve, and the KTM slid to fifth place in this year's standings.
