02. The strongest start
UNMATCHED PERFORMANCE
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 KTM 2026 450 SX-F FACTORY EDITION boasts one of the strongest and most versatile 4-stroke powerplants in the paddock, with its SOHC engine proving to be the perfect example of advanced engineering. With a peak power output, and an overall engine weight of only 26.8 kg, you'll leave the competition with more than a little mud on the face. The Akrapovič silencer fitted to the 2026 KTM 450 SX-F FACTORY EDITION has been updated to meet the current FIM noise limit of 109 dB(A). Crafted from lightweight titanium, it features a premium finish that reflects its high-performance design -- and is available exclusively on this limited-run model.
DUMP THE CLUTCH
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.
TOTAL TRACTION
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.

03. Establishing the edge
SCRUB CLEANER
Absolute Control
Get ready for a full-on berm assault. The 2026 KTM 450 SX-F FACTORY EDITION received major frame updates directly from KTM Factory Racing efforts. For starters, the area around the rear shock mount is streamlined, with engine mounts and cut-outs for improved chassis flex. The front area of the frame has an optimum wall thickness with renewed engine mounts. This adds up to a 300g weight saving and improved flex for better cornering.
FULL FLOW ON THE GO
Ergonomics
Upgraded 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.
UNMATCHED PERFORMANCE
Performance
The 2026 KTM 450 SX-F FACTORY EDITION engine is tilted 2° backward, this means greatly improved mass centralization and reduced overall weight, benefiting handling and anti-squat behavior. A silencer offers an improved response in combination with the mapping switch and provides a slightly quieter exhaust note.

NO HOLDS BARRED
Ground clearance
No one enjoys a bad hook-up. Good thing, then that 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.
PRECISION, LAP AFTER LAP
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.
SOFTER IMPACT
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.
All THE STYLE
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.
