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.
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.
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.
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.

03. STYLE AND FUNCTION
RACE TO COMFORT
Ergonomics

TAKE A SEAT
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.
FIND YOUR FOOTING

04. ALL-IN AGILITY
THE BACKBONE
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.
CURVED PIVOT
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.
SPRING INTO ACTION
Fork
Upfront, a 43 mm WP APEX open cartridge fork with 150 mm travel keeps things in check, with adjustable compression and rebound settings.
MAX TRACTION
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.
ROLLING THUNDER
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.
STOPPING POWER
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.
