2026 KTM 390 Duke

THE CORNER ROCKET

With the KTM 390 DUKE, the world around you becomes your very own gymkhana. Bringing exceptional agility, lightweight handling, and punchy performance to the street, this middle-weight bruiser is ready to take on any twists or turns. Packing state-of-the-art rider aids, an all-new frame, adjustable suspension - and aggressive new looks - the KTM 390 DUKE wears the crown when it comes to carving up the asphalt.

Features may include:

CLUTCH IN, REVS UP!
  • ADJUSTABILITY

Finding that perfect balance when attacking your favorite stretch of tarmac, or sliding around some tight cone-marked corners is easy thanks to the KTM 390 DUKE's 43 mm WP APEX open cartridge fork with adjustable compression and rebound. On the rear, the WP APEX Separate piston shock absorber can also be set for rebound and preload, to find the ideal mix between comfort and traction.

3, 2, 1 - LAUNCH!
  • ENGINE

Boasting the latest generation in LC4c engines, the KTM 390 DUKE muscles up with a 399 cc capacity, more power, smoother acceleration, and lighter overall weight than the previous generation. Drawing from years of experience in the small engine game, the KTM 390 DUKE now also features an improved gearbox, and an optimized cylinder head, and is ready to adopt EURO5+ emission standards. Oh, and did we mention it is also READY TO RACE?

STYLE AND FUNCTION
  • FOOTPEGS

Lightweight forged aluminum footpeg hangers and grippy footpegs ensure riders have uninterrupted grip when banging through the gears, with high-end CNC-machined footpegs available from the KTM PowerParts catalog.

ALL-IN AGILITY
  • FRAME

The frame features a 2-piece construction composed of a steel trellis main frame with a pressure die-cast aluminum subframe. The rear shock absorber is mounted off-center to allow for a larger airbox while reducing seat height and, at the same time, adding to the DUKE's aggressive stance. Not only designed for looks, the primary objective of the frame design is to enhance vehicle dynamics by augmenting torsional rigidity, improved agility, and enhanced feedback from the chassis.
