THE BASE FOR THE BEST: 2026 KTM SX-F FACTORY EDITIONS ON A ROLL
Taking the exceptional and title-winning current platforms of the KTM 450 SX-F and KTM 250 SX-F – motorcycles that gathered main event victories in 2025 – the 2026 KTM SX-F FACTORY EDITIONs represent the ultimate competitive upscale.
What can customers expect beyond the ferocious power from the 47 hp and 63 hp mass-centralized, compact sub-27 kg engines? Also, the acute handling thanks to the light, hydro-formed, laser-cut and robot-welded frames with precision longitude and torsional flex, plus a polyamide reinforced aluminum 2-piece subframe and hollow, die-cast aluminum swingarm? Or how about race-bred detailing like CNC triple clamps, Brembo hydraulic clutch and Brembo brakes, ODI lock-on grips, wide, no-mud footrests, a Quickshifter, launch control and traction control? Not forgetting the Connectivity Unit Offroad (CUO) for even more set-up possibilities.
Answer? Firstly, the components and tuning of WP PRO COMPONENTS as standard. The revised hardware and settings of the WP XACT PRO 7548 front fork and WP XACT PRO 8950 shock mean a significant modification for durability and feeling in tune with the pinpoint ergonomics of the 2026 KTM SX-F FACTORY EDITIONs. This is the ultimate in suspension system technology, offering substantial possibilities for personalization and adjustment. The 48 mm fork has a unique cone valve system (shim-less) with a 310 mm stroke and 23 mm piston diameter. Riders, depending on their size and ability, can choose between 15 different spring rates, available at WP authorized centers. Compression, rebound and damping can be tweaked to the millimeter, and the CUO and the KTMconnect App can also help in this regard. Count on comfort, response and the best protection from ‘bottoming’. The shock has the same glut of options to prioritize traction and stability. It weighs just over 4 kg to minimize unsprung mass and works in succinct harmony with the fork and chassis behavior. In short, KTM is now offering ‘factory’ suspension in production trim and available to all.
Elsewhere improvements with the KTM SX-F FACTORY EDITIONs can be felt in practicality and resistance against the gnarliest of track conditions thanks to a new radiator closure (also making for easier access) and a freshly designed protection cap for the fuel line quick-lock system. Careful engineering with the airbox, air filter and fuel injection along with collaboration with partner Akrapovic means the 109-decibel noise level, FIM compliant, can be met with the remodeled titanium silencer without loss of the trademark KTM SX-F torque and power.
Finally, the finishing touches. KTM SX-F FACTORY EDITIONs would not be official without the very latest Red Bull KTM Factory Racing graphics and detailing. Choose from Tomac or Plessinger race numbers and smirk as the 2026 incarnations look the absolute ‘boss’ of any start gate. Other visual touches such as the orange 2026 FACTORY EDITION frame, black wheels, orange factory seat are the markers of class.
