KTM lives and breathes a READY TO RACE mantra, and the FACTORY EDITIONS are special, limited-run models that erase the last few spec variances between what is ‘stock’ and what is ‘factory’. It’s then up to the rider how much they want to make the difference: how fast are you and how much do you want it? The KTM 450 SX-F FACTORY EDITION inherits the basis of the 2025 peerless KTM SX-F motocross racers and then, thanks to a list of KTM POWERPARTS additions, gets as close to the Pros as its possible to be. This specific bike comes with an innovative Connectivity Unit that allows more interaction and setup possibilities than ever before. The KTM 250 SX-F FACTORY EDITION has been crafted by racers for the ultimate racecraft.
