FULL-SIZE FIREPOWER: KTM SX & SX-F MODELS LEAD THE PACK
The 2026 lineup remains on top of the podium thanks to KTM's SX philosophy of agile handling and race-winning power. Every model is equipped with class-leading electronics, refined chassis dynamics and explosive power delivery. Riders aiming for factory-level precision can unlock full adjustability with the optional Connectivity Unit Offroad (CUO). Paired with the KTMconnect app, it enables fine-tuning of engine behavior, traction control, and suspension settings.
The settings and configuration of the full size KTM SXs and KTM SX-Fs come from the substantial success and learnings of competition in the FIM Motocross World Championship (wins in both MXGP and MX2 classes with the KTM 450 SX-F and KTM 250 SX-F) and the AMA Supercross and Motocross series. Depending on the market there are also options with a default noise decibel limit to adhere to FIM guidelines from the start of the 2025 calendar year. The latest model lineup is easy to detect on all models with a revitalized orange aesthetic, the principal color and graphics now also embracing a shade of purple on the tank spoilers and fork guards. The frame is powder-coated black with a matching black seat.
KTM has tweaked the radiator closure to be more standardized and for easier access on all KTM SXs. Where applicable, all fuel injection units have a new protector cap for the fuel link quick lock system that will beef-up durability and also assist with maintenance. The 2-stroke KTM SXs have an improved wiring harness routing and the adjustments of the fixing points and organization represent another effort for resistance against the elements.
THE NEXT GENERATION OF RACERS STARTS HERE
KTM’s commitment to providing the widest and highest quality platform of progression for young riders is steadfast for 2026. KTM Sportminicycles remain a cornerstone of development, giving young riders the tools to start their journey – from first laps on the electric KTM SX-E models to racing progression with the KTM 50 SX and KTM 85 SX.
Fun or first place? The 2026 KTM Sportminicycles will carry youth on their way. The KTM 50 SX and KTM 65 SX benefit from a new WP XACT AER front fork with a renewed air cartridge and sealing concept for better damping, control and overall performance. The radiator closure has been tweaked to be more standardized and for easier access same as on the bigger KTM SX models. The triple clamps for the KTM 50 SX, KTM 65 SX and KTM 85 SX now have the same 17 mm wrench size and closed screw nut format as the full size KTM SXs to add a further barrier against dirt and water intrusion. On the theme of resistance, the throttle cable assembly is less prone to kinking and deformation thanks to a new stabilization cap.
The 2026 KTM 65 SX takes the next for maximum durability with an overhauled clutch fixation system in place. The pre-coating and increased torque tightening mean a step up in terms of excellence. Running through these KTM SXs, a new laser-cut exhaust flange gasket promotes more reliability and the exhaust valve ventilation emanating from the cylinder has been redesigned in Austria with the same mission in mind. The KTM 85 SX has been given a new rear brake lever with two adjustment options for length to the brake tip. This will help in terms of set-up for different sized kids who are making the transition from the KTM 65 SX to the bigger 85 SX.
The KTM 50 SX FACTORY EDITION is for any child that is already fantasizing of checkered flags and does not tire of watching their racing heroes. The READY TO RACE KTM PowerParts components and factory team replica livery will pull them closer to the dream and create a tight link to Red Bull KTM Factory Racing stars.
