New 2026 KTM SX & SX-F Models Specs

Refinements enhance KTM’s motocross lineup for 2026. Both the SX (50, 65, 85, 125, 250 and 300) two-stroke and SX-F (250, 350 and 450) four-stroke ranges see mostly minor updates, with few changes.

KTM has tweaked the radiator closure to be more standardized and easier to access on all KTM SX models by reducing the force needed. Where applicable, all fuel-injection units now feature a new protector cap for the fuel-link quick-lock system, which is said to improve durability and aid maintenance. The two-stroke KTM SX models have upgraded wiring-harness routing and adjustments to enhance resistance against dirt intrusion.

The 50cc, 65cc and 85cc SX models feature new triple clamps with matching 17mm wrench sizes and a new closed screw nut to protect against debris. A new stabilization cap has been added to the throttle-cable assembly for better sealing against water intrusion. Additionally, the 65 SX has a redesigned clutch-fixation system for increased durability; the 85 SX has a new brake lever with two adjustment positions, and the 50 SX includes several revisions to enhance durability. Both the 50cc and 65cc SXs are equipped with upgraded WP Xact Aer forks.

Manfred Edlinger, head of motocross development, said, “We’re in the fourth year of the current generation for the KTM SX full-size models, third for the KTM 50 SX and 65 SX, and the second for the KTM 85 SX. 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 range has been restyled, 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 KTMs will satisfy the hungriest little racer and their family.”
