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 a fresh chassis, and a 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.

Easy Suspension Adjustment

Like the rest of the KTM- SX-F range, the KTM 450 SX-F FACTORY EDITION comes with totally tool-free suspension setup at both ends. The shock absorber design features hand-adjustable dual compression control, it allows riders to tweak high- and low-speed settings in a matter of seconds. On the front end, the forks are also easily changeable thanks to a single air pressure preload valve, as well as easy access click adjusters for compression and rebound. We'll even throw the air pump in as standard.

Air filter box

The KTM 450 SX-F FACTORY EDITION uses a one-piece construction of the air inlet sleeve and snorkel for more durability and less possibility for air deformation. Designed to provide maximum airflow, the air filter box also comes with a special white vented cover. The Twin Air filter and air filter support have a simple fail-proof mounting system for safe and accurate filter installation, ensuring the filter is easily accessed and therefore easy for maintenance.

Customization

Shape your KTM 450 SX-F FACTORY EDITION quickly and easily with the Connectivity Unit Offroad. This two-part system is mounted between the right fork leg (protected by the shape of the number plate) and the GPS component on the redesigned front fender. The 'CUO' enables a wealth of easily adjustable options for engine behavior and suspension settings via the KTMConnect App. But that's not all. An official affiliation with LITPro will empower all riders to examine their lines, speed, air-time, throttle position, and other information to make their lap-times worthy of the KTM 450 SX-F FACTORY EDITION.

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 tilted 2° backward, resulting in a 3mm 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 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 KTM 450 SX-F FACTORY EDITION package

Absolute Control

The glossy orange frame is a key refinement of the KTM 450 SX-F FACTORY EDITION. Different wall thickness and cutaway sections have improved the degree of flex and trimmed away significant weight. The chassis concept remains strong and Red Bull KTM FACTORY RACING continues to win races and set records at the highest level with the same principle. The chassis repositions rotating mass closer to the center of gravity. The shock mounting also provides improved anti-squat behavior to better traction out of corners, while the footpeg mounting position has moved inwards for less risk of hooking up in deep ruts or when scrubbing jumps.

Ergonomics

The KTM 450 SX-F FACTORY EDITION features a refined rider triangle, providing improved knee contact - especially when standing on the pegs - with improved gripping surfaces all around. The plastics work to expel mud buildup in wet, muddy conditions. A flatter seat profile with a ribbed FACTORY seat cover - lighter, thinner, more resistant - permits exceptional rider movement and control. The polyamide reinforced aluminum subframe further enhances rider feel and feedback.

The most obvious sign that the KTM 450 SX-F FACTORY EDITION is on track and creating an orange blur is evident through those unmissable graphics. Mimicking the look and shade of the Red Bull KTM Factory Racing right down to the last centimeter, the 2025 editions also come in the #4 and #7 number options for racers Chase Sexton and Aaron Plessinger respectively.

WP XACT Fork

Count on 310mm of travel with the 48mm air type WP XACT front fork, with a split damping function providing all the confidence you need to attack the track. The KTM 450 SX-F FACTORY EDITION's forks come with hydrostops in the fork legs improving bottoming-out resistance and account for less rebound when attacking big jumps and bumps. Fork protection rings also increase protection against dirt, making them as reliable as they are awesome.

Hard Braking

Another KTM 450 SX-F FACTORY EDITION upgrade is the stiffer and tougher rear brake pedal material that will pull the full power of the Brembo systems into play. The pedal is more resistant to unwanted contact and obstacles. The braking force is augmented by the semi-floating 260mm front brake disc and the carbon reinforced FACTORY brake guard.

A WP XACT rear shock absorber provides unmatched consistency lap after lap, thanks to new low-friction linkage seals and advanced damping characteristics for unsurpassed traction and energy absorption. To suite the KTM 450 SX-F FACTORY EDITION linkage settings have been reworked for optimal weight saving and stiffness. The linkage bolt is smaller and lighter and transferred directly from successful use by the Red Bull KTM Factory Racing team.
