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.

Bodywork

Embracing its NAKED lineage, the KTM 390 DUKE has no shame in bearing it all. Casting an ever-impressive shadow, bristling with shark-like edges and visible air intakes, the KTM 390 DUKE boasts an aggressive stance. A metal fuel tank, color-injected plastics, and external LED positioning lights complete the package.

Graphics

Premium looks come standard on the KTM 390 DUKE. A high-quality, multi-layered, wet-painted finish in either Electronic Orange or Atlantic Blue with clear-gloss graphics perfectly set off the unique DUKE textured seat cover. Make no mistake, this is 100% DUKE with 110% street-cred.

Engine

Boasting the latest generation in LC4c engines, the KTM 390 DUKE flexes its muscles with a 399 cc capacity, exceptional power, smooth acceleration, and light overall weight. Drawing from years of experience in the small engine game, the KTM 390 DUKE also features the same updated gearbox, and optimized cylinder head as released in the 2024 model year.

Ride Modes

The KTM 390 DUKE gives its pilots a selection of RIDE Modes to best suit whatever conditions they find themselves in. With STREET Mode activated as standard, this unleashes all the KTM 390 DUKE's fury, while RAIN Mode works to keep things a little more controlled in the wet. For flat-out track enthusiasts, we now give you a dedicated TRACK Screen! All are easily toggled in via the TFT display.

Track Screen

TRACK Screen transforms the 5" TFT display graphics to be more race-focused, enlarging the rev counter, showing the laptimer, selected gear display, reduces the size of the speed readout, and shows preferred rider aid settings. What's more, TRACK Screen also allows riders to initiate Launch Control.

Launch Control

Get ready to rocket off the line, because, for the first time ever, the KTM 390 DUKE comes equipped with Launch Control as standard. With the TRACK Screen selected and Launch Control engaged, the engine will peak at 7,000 rpm with a wide open throttle, waiting for the rider to release the clutch.

LED Lighting

Tearing a deep gash into the night, all KTM DUKE models come equipped with powerful LED lights in the front and at the rear. Not only do these work when the world becomes dark, but they also provide improved visibility when navigating busy traffic or misty road conditions.

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.

Seat

Excellent comfort for the rider and pillion, thanks to thick seat foam, a narrow profile, and racy ergonomics. Need for more or less seat height? The KTM 390 DUKE has a standard seat height of 820 mm, but can easy be decreased to 800 mm with the optional KTM PowerParts seat offering.

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.

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.

Swingarm

A curved cast aluminum swingarm provides a sturdy and durable platform for the rear suspension system, featuring a direct shock absorber mount that is offset to the side, for that super-racy look. This also creates additional space for the new exhaust muffler, providing added attitude.

Fork

Upfront, a 43 mm WP APEX open cartridge fork with 150 mm travel keeps things in check, with adjustable compression and rebound settings.

Rear Shock

On the rear, you'll find an off-center WP APEX Separate piston shock absorber with 150 mm of travel and 60 mm of stroke. Rebound is easily adjusted with a 5-step clicker, and is also preload adjustable.

Wheels and Tires

Reducing weight where it counts the most, the KTM 390 DUKE's rims are wrapped in grippy Michelin Power 6 tires. This not only improves the overall handling characteristics but also means quicker turn-in and less strain on working components like axels and bearings.

Brakes

On the front wheel, the KTM 390 DUKE boasts a 320 mm brake disk with four-piston radial calipers. The design includes large disks to reduce the operating temperature with improvements in the resistance to fading and longer pad lifespan. On the rear wheel, a 240 mm brake disk is installed with a single-piston caliper which carries the same benefits as the front wheel. Cornering ABS and SUPERMOTO ABS are also standard features.
