KTM has revealed its full 2026 SX motocross lineup, covering everything from 50cc juniors through to the championship-proven 450 SX-F.

- KTM 85 SX
Full-size Motocross Range:

Full-Size Power and Precision
KTM’s full-size SX and SX-F machines continue to lead from the front, with aggressive handling, proven race-winning engines, and a sharp electronics package as standard. Riders chasing a factory feel can unlock full adjustability with the optional Connectivity Unit Offroad (CUO), which works with the KTMconnect app to fine-tune engine mapping, traction control, and suspension settings.
The 2026 bikes carry forward R&D gains made through top-tier competition, including wins in MXGP, MX2 and AMA Supercross. In some markets, select models are available with reduced default noise levels to meet 2025 FIM standards.
KTM has also refreshed the look of the SX range. Expect bold new in-mould graphics with a strong orange base, purple accents on the tank shrouds and fork guards, a black powder-coated frame, and a matching black seat.
Key updates for 2026 full-size SX models:
- Revised radiator closure for easier access and improved standardisation.
- New fuel injection connector cap for better protection and easier maintenance.
- Improved wiring layout on 2-strokes to boost long-term durability.
A Platform for the Next Generation
KTM continues its commitment to youth development with a heavily updated Sportminicycle range, offering young riders a solid platform for fun or competition.
The KTM 50 SX and KTM 65 SX now feature an improved WP XACT AER fork with updated air cartridge and sealing for better damping and control. A revised radiator closure system makes maintenance easier, while the triple clamps on the 50 SX, 65 SX and 85 SX now share the 17mm wrench size and closed screw nut format from the full-size bikes—boosting protection and ease of servicing.
Other key 2026 Sportminicycle updates:
- New throttle cable cap for added resistance to kinks and wear.
- KTM 65 SX clutch upgrade: reinforced fixation system with pre-coating and increased torque for greater longevity.
- New exhaust flange gasket and redesigned cylinder ventilation across the mini range improve reliability.
- KTM 85 SX receives a new rear brake lever with two adjustable positions to suit growing riders transitioning from 65cc.
The KTM 50 SX FACTORY EDITION is designed for kids dreaming of the big time. With factory-style graphics and KTM PowerParts upgrades, it offers a real taste of the pro life.
2026 KTM SX Range Highlights:
- 10-model lineup covering junior and full-size motocross needs.
- Updated WP suspension, clutch components and increased durability across the range.
- Bold new 2026 graphics and colourway: orange base with purple details, black frame and seat.
- Optional CUO and KTMconnect app for custom mapping and suspension adjustment on full-size models.
- Wide range of KTM PowerParts and KTM PowerWear available for personalisation and protection.
“We’re in the fourth year of the current generation for the full-size SXs and continue to make smart refinements,” said Manfred Edlinger, Head of Motocross Development. “The new models offer more than just looks—they deliver better componentry, improved resistance to wear, and keep KTM ahead as the choice for aspiring and elite racers alike.”
The 2026 KTM SX range will be available in Australia from October 2025, and in New Zealand from November 2025 through authorised KTM dealers. Details on the 2026 SX-E electric line-up will be announced later this year.
