2025 KTM 450 SX-F FACTORY EDITION

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 450 SX-F FACTORY EDITION has been crafted by racers for the ultimate racecraft. Try to catch it.

Selectable Maps + TC

The map select switch on the KTM 450 SX-F FACTORY EDITION features a simple design, allowing for easier functionality in switching between 2 engine maps. Map 1 provides a more linear power curve. while map 2 punches all-out with aggressive throttle and explosive delivery. Luckily, traction control is easy toggled to an on-or-off position from the same switch, ensuring maximum traction and a distinct advantage in wet or muddy conditions.

Launch Control & Quickshifter

The KTM 450 SX-F FACTORY EDITION uses launch control and a Quickshifter function, allowing for fast upshifts without using the clutch. Launch control is easily engaged by pressing the traction control and Quickshifter buttons simultaneously and works by limiting the amount of power to the rear wheel, improving traction, and preventing loss of control under hard acceleration. Meanwhile, the Quickshifter function means you can bang through from 2nd to 5th gear with your focus solely on the first corner. Honing starts is made easier with the KTM 450 SX-F FACTORY EDITION due to the WP FACTORY START DEVICE that lends useful compression on the front forks and is easily engaged and then disengaged when blasting into action.

More Usable Power

The KTM 450 SX-F FACTORY EDITION boasts one of the most manic 4-stroke powerplants in the pits, with its SOHC engine proving to be the perfect example of advanced engineering. The engine is positioned to lower front sprocket position, meaning greatly improved mass centralization. Fixed on special black 'race' mounts to help with chassis flex, and an overall weight of only 59 lb (26.8 kg), this motor will leave the competition with more than a little mud on the face. An Akrapovic slip-on exhaust not only adds an important aesthetic to the KTM 450 SX-F FACTORY EDITION but also peels away more weight and adds even more punch to the power.

The parts that count

Marginal gains on the track are sought out through the strength of the details. The weight-saving, robustness and performance potential of components such as the FACTORY orange rear sprocket, gold chain, DID FACTORY wheel set and Dunlop GEOMAX tires -that promise performance and versatility - are other unmistakable elements of the 2024 KTM 450 SX-F FACTORY EDITION package.

Powering protection

The Dunlop Geomax MX34 tires are the latest offering from the factory with a carcass designed for optimal damping and absorption and for an improved 30% longer distance. The MX34 also has improved block technology (taller and wider) for better dispersion, traction, and control, with a special rubber compound also raising the game for durability.
