2026 KTM MX range breaks cover
By Team TMX on 31st Jul 25
Legendary Austrian motorcycle manufacturer KTM has announced details of its 2026 range of 10 motocross models from the 50 SX through to the MX1-class leading 450 SX-F.
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 behaviour, traction control, and suspension settings.
The latest model lineup is easy to spot with a revitalised orange aesthetic, the principal colour 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 standardised 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 assist with maintenance. The two-strokes have an improved wiring harness routing, and the adjustments of the fixing points represent another effort for resistance against the elements.
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.
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 standardised and for easier access, similar to 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 stabilisation cap.
The 2026 KTM 65 SX takes durability to the next level 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 a wider range of rider sizes who are making the transition from the KTM 65 SX to the bigger 85 SX.
“We’re in the fourth year of the current generation for the KTM SX full-size models, the third for the KTM 50 SX and 65 SX and the second for the KTM 85 SX,” says Manfred Edlinger, Head of Motocross Development. “The bikes keep moving from strength to strength as we find measures and changes to make sure we stay at the forefront of choice for all racers. The whole full-size range has been re-styled, but we’ve also found ways to bolster the KTM Sportminicycles because we know the components, the performance and the technical base of these special KTM bikes will satisfy the hungriest little racer or their supportive family. Embrace the ‘bar’ again, because we’re pumped to continue lifting it in motocross.”
All 2026 KTM SX motorcycles will be available at authorised KTM dealers from August 2025.
