KTM has pulled the covers off its 2026 Enduro range, and this years headline is a big one: the 300 EXC is now the only street-legal two-stroke in Europe.
The reason? Stricter EURO5+ emissions regulations, which have forced KTM to reclassify the 125, 150, and 250cc two-strokes as XC-W competition-only bikes.
For many riders, this is a bittersweet moment a nod to how much the market has changed, but also a sign of how KTM continues to adapt.

Europe:

  • 125 XC-W (competition only)

  • 250 XC-W (competition only)

  • 300 EXC (EURO5+ homologated)

  • 250 EXC-F, 350 EXC-F, 450 EXC-F, 500 EXC-F (four-stroke range)

North America:

  • 150 XC-W, 250 XC-W, 300 XC-W (competition)

  • 450 XCF-W (dual-sport)

  • 350 EXC-F & 500 EXC-F to be announced in coming weeks

KTM describes the 2026 Enduro platform as being chiselled which in real terms means changes youll feel on the trail:

  • 48mm WP XACT Closed Cartridge forks: New damping settings, shorter and lighter springs, reworked pressure reservoir geometry, and a one-piece hydro stop for better end-stroke control.

  • Weight savings: 200 grams from the forks alone.

  • WP XPLOR PDS rear shock: Adjusted to match the updated fork performance.

Riders have long asked for better cooling straight from the factory, and KTM has finally listened:

  • Radiator fan now standard on the 300 EXC, all EXC-Fs, and the 450 XCF-W.

  • New radiator cap with standard thread easier and faster to open.

  • Fuel connector cover to keep dirt and water out, plus an extra seal for extra reliability.

2026 isnt just about performance KTM has also sharpened the look and feel:

  • Brighter in-mold graphics with vivid orange and red fork guard accents.

  • Re-shaped tank spoilers for better airflow and cooling.

  • High-grip black seat, textured frame protectors, updated bar pads.

  • OEM tyres: Maxxis for Europe, Dunlop Geomax AT82 for North America.
