before the gate

Factory-level hardware

The 2026 KTM 450 SX-F FACTORY EDITION raises the bar with a factory-level suspension upgrade that redefines READY TO RACE performance. Fitted as standard with the WP XACT PRO 7548 front fork and WP XACT PRO 8950 rear shock, this exclusive setup delivers unmatched precision, comfort, and control. The 48 mm WP XACT PRO 7548 fork features a closed-cartridge design with a unique valve system and friction-optimized internals, offering pinpoint response, rock-solid bottoming resistance, and consistent damping lap after lap. On the rear, the WP XACT PRO 8950 shock incorporates Supertrax technology and a linked damping system to maximize traction, smooth out harsh impacts, and boost rider confidence in every section of the track.

Air filter box

Made to provide maximum airflow, the air filter box is designed with positioned inlet ducts aimed at preventing air deformation and maintaining filter protection. The Twin Air filter and air filter design involve a simple fail-proof mounting system for safe and accurate tool-less installation. Quickly removing the left side panel allows for easy track-side maintenance. A vented air filter box cover is also included for all SX and SX-F models in the buy-pack.

Serviceability

The 2026 KTM 450 SX-F FACTORY EDITION is engineered and designed to provide riders with easy-to-access service parts, as well as suspension adjustability. This permits faster trackside and off-season maintenance, as well as simplifying motocross for novice riders without pit crews. This year, to add the cooling process, the radiator has a new closure that means opening and access is much easier and without the need for a lot of force.

the strongest start

More Usable Power

When the gate drops you need to be the first to off the line in a bid to rule (and make) the roost. The 2026 KTM 450 SX-F FACTORY EDITION boasts one of the strongest and most versatile 4-stroke powerplants in the pits, with its SOHC engine proving to be the perfect example of advanced engineering. With class-leading peak power output, and an overall engine weight of only 59 lb (26.8 kg), you'll leave the competition with more than a little mud on the face. The 2026 KTM 450 SX-F FACTORY EDITION features an updated Akrapovič muffler, intake, and mapping, which increases rideability while meeting the latest FIM and AMA sound regulations. Crafted from lightweight titanium, the muffler's premium finish reflects its high-performance design -- and is available exclusively on this limited-run model.

Launch Control & Quickshifter

Ace that holeshot! The 2026 KTM 450 SX-F FACTORY EDITION comes standard with launch control and a Quickshifter, 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 means you can bang through from 2nd to 5th gear with your focus solely on the next 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.

Selectable Maps + TC

The map select switch on the 2026 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 power. 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. In term of FI upgrades, for 2026 there is a new fuel protector cap: you'll still have quick and easy access for maintencance but now more safety against any outside damage and accidental opening as well as preventing dirt from entering the sides of the connector.

establishing the edge

Absolute Control

The 2026 KTM 450 SX-F FACTORY EDITION frame is built for riders who demand sharp handling and full control. Its refined flex characteristics let you carve berms, launch jumps, and tackle technical terrain with confidence. A streamlined rear shock mount boosts stability and traction, while optimized engine mounts and wall thickness ensure a balanced, responsive feel from front to back.

Ergonomics

Tank shrouds using bi-compound plastics channel air towards the radiators more efficiently, while a concise fuel tank roll makes for a tighter, more secure fitment, reducing the chance of frame scrubbing and dramatically improving durability. All this works alongside the specially developed rider triangle to provide unmatched knee contact and gripping surfaces - especially when standing on the pegs.

Performance

The 2026 KTM 450 SX-F FACTORY EDITION engine is positioned for optimal mass centralization and reduced overall weight, benefiting handling and anti-squat behavior. The silencer offers incredible response in combination with the mapping switch and provides a slightly quieter exhaust note.

tackling the tough

New WP PRO Suspension

The 2026 KTM 450 SX-F FACTORY EDITION now features the class-leading WP XACT PRO 7548 fork and WP XACT PRO 8950 rear shock. This means you'll be lining up at the setting gate with the ultimate set-up, reduced weight, pristine weight distribution and acute responsiveness.

WP XACT PRO 7548 FORK

The 48 mm WP XACT PRO 7548 fork, fitted as standard, represents the pinnacle of motocross suspension -- adding a new layer of performance and adjustability. More than just suspension, it's a secret weapon for faster lap times and total confidence in every section of the track. It delivers unrivaled comfort, pinpoint response, and rock-solid bottoming resistance to the MY26 FACTORY EDITIONS. The XACT PRO 7548's unique valve system and friction-optimized components work in harmony to absorb harsh landings without compromising support, delivering consistent damping lap after lap and instilling rider confidence in all track conditions.

WP XACT PRO 8950 SHOCK

The WP XACT PRO 8950 shock absorber is engineered for ultimate traction, comfort, and confidence on every lap. Featuring Supertrax technology to smooth out harsh impacts, a linked damping system for maximum tire contact, and friction-optimized components for improved feedback, it delivers consistent performance in all conditions. Fully adjustable for high- and low-speed compression, rebound, and spring preload, it's built to handle the toughest motocross demands while remaining lightweight at just 4.078 g. With a stroke of approx. 139 mm, a 240 mm spring, and a 50 mm piston, it's precisely tuned to the frame geometry and works in perfect harmony with the WP XACT PRO 7548 front fork.

Stability

The 2026 KTM FACTORY EDITION range features a forged steering head connection and adjustable, orange-annodized, CNC-milled Factory triple clamps, making for the perfect alignment of the fork tubes. This precise geometry of the fork clamps ensures highly responsive and smooth fork action - not to mention unwavering stability when charging across ruts and onto the podium.

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, D.I.D Factory wheel set and Dunlop GEOMAX tires -that promise performance and versatility - are other unmistakable elements of the 2026 KTM 450 SX-F FACTORY EDITION package

Tires

Getting power hooked into the dirt is a tough job. However, hours of research and testing have led the 2026 KTM Motocross range to the Dunlop GEOMAX MX34. Providing unmatched stability and control at the highest level, the rubber features a rigid carcass and rubber compound that improves damping and absorption, maintaining performance up to 30% longer than previous models. Progressive Cornering Block Technology also improves grip in the berms, while the rear pattern has a tall and wide center block for desirable traction and control everywhere else. Lastly, this unique block arrangement works to dispel mud buildup, ensuring traction in even the muddiest of track conditions.

Ground clearance

The shock absorber geometry on the 2026 KTM 450 SX-F FACTORY EDITION improves ground clearance of the linkage, with the topology-optimized die-cast footpegs being less susceptible to hooking on deep ruts, and take-offs when scrubbing.

Consistency

Count on a durable chain guide and chain guard and minimize the chances of hooking on external objects - especially in extremely muddy terrain while reducing dirt build-up around the swingarm and rear sprocket.

Energy absorption

Besides the expertly crafted, hydro-formed, laser-cut, and robot-welded frame being engineered to provide exceptional rider feedback and straight-line stability, the chassis consists of specifically calculated parameters of longitudinal and torsional flex. This means the frame acts as a "shock absorber" of sorts, making for a less harsh ride, resulting in less rider fatigue over many hard laps.

New graphics & Colorway

The 2026 KTM 450 SX-F FACTORY EDITION features bold new colors directly inspired by the Red Bull KTM Factory Racing team. A deeper, more vibrant KTM orange is paired with striking blue accents and a Selle Dalla Valle seat combo -- designed to stand out at speed and on the gate. All graphics are ultra-durable thanks to in-mold technology, ensuring the bike looks sharp lap after lap.
