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.

This motorcycle is designed and developed in Austria, and assembled in India.

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 before. 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. Oh, and did we mention it is also READY TO RACE?

STYLE AND FUNCTION
  • Ergonomics

Thanks to a long wheelbase, a low seat height, and excellent frame geometry, the DUKE range boasts incredible cornering behavior, stability, and handling proficiency. This, along with an already sterling reputation as being a THE CORNER ROCKET and an aggressive seating position, means the KTM 390 DUKE sets the standard when it comes to energetic NAKED machinery.

ALL-IN AGILITY
  • Frame

The design 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 the large airbox which allows for the lower 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, nimble agility, and enhanced feedback from the chassis.
