Back in 2012 Roger DeCoster knew that recently hired Ryan Dungey needed a better bike for the 2013 AMA season that was offered in KTM’s 2012 inventory. Roger talked KTM management into making a special run of 400 2013 KTM 450SXFs so that they could be sold to the public to make the 2012-1/2 KTM 450SXF Factory Edition AMA-legal for the 2013 season. Ever since then. KTM has given consumers the opportunity to buy next year’s bike several month before the actual production model is made. Some years the KTM Factory Editions are earth-shattering, but just as often, the Factory Editions are just gussied-up production bikes. The 2020-1/2 KTM 450SXF Factory Edition is highlighted by a factory-installed holeshot device, floating front brake rotor, a slip-on Akrapovic muffler, Selle Dalla Valle seat cover, orange anodized hubs, updated fork valving and Red Bull Factory team graphics.
