After an extremely successful season in both the racing world and in sales with the first 450 SX-F Factory Edition, KTM took a long look at the model and looked for ways to improve the US National championship winning machine. As the most powerful bike in the class, there would be no need to redo the engine. Instead, they focused on handling improvements, which comes by dropping a pound and a half from last year’s release.
Race ready in every way, the bike becomes the icon of the Austrian brand’s motocross division. It, along with the 2013 Red Bull KTM race team, team was unveiled to the press at the team’s Murrieta, CA, headquarters.
Now a pound and a half lighter than before, KTM states the new bike’s handling has improved more. KTM is the only OE of the “big five” to use a chromoly frame and we spoke with the staff about the steel chassis and if they have experimented with aluminum. They in fact have worked with a number of frame designs, including aluminum and a trestle style, but only the steel frame has handled to their liking.
