TFT-DISPLAY
A multicolor combination of relevant information, presented in an uncluttered way. As you rev the engine, the display bars change color, either spurring you on or warning you that the engine's still cold. The display also automatically adapts its illumination to the ambient light and gets racy when "Track mode" is selected.
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.
TFT-DISPLAY
Everything you need at a glance. The KTM 390 DUKE features a 5" bonded glass TFT dashboard. This is paired with a switch cube set that has 4-way menu switches that allow easy interaction with all vehicle functions - even smartphone connectivity. Speaking of which, All DUKE models are equipped with connectivity functions, allowing pilots to play music, take incoming calls, and get to where they are going with Turn-by-Turn.
Bodywork
100% DUKE. Purposefully NAKED and proud of it, the KTM 790 DUKE presents an aggressive stance, boasting aggressive lines and clearly obvious intentions. As the original scalpel, it's sharp, to the point, and leaves nothing covered.
LED HEADLIGHT
With an LED headlight adding to the KTM 790 DUKE's menacing look and subtracting from the darkness, illumination is taken care of when charging into the night. Flanked by two LED strips that function as running lights, being seen during the daylight hours is taken care of too.
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.
Engine
Developed for torque, this liquid-cooled 8-valve, DOHC unit delivers 87 Nm at 8000 rpm, almost immediately followed by a roaring 105 hp finale - 95 hp version for the L model that is available in certain markets. Meanwhile, an advanced ride-by-wire system guarantees great refinement as well as low fuel consumption and emission figures. It roars too.
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.
RIDE MODES
Riders can choose from four ride modes, namely SPORT, STREET, RAIN, and TRACK. Naturally, STREET MODE is the default, making for comfortable urban riding, with RAIN MODE taking care of things when they get a little slippery. SPORT MODE is used when needing to dial things up a notch, with TRACK MODE giving KTM 790 DUKE pilots full power output, and the ability to dial down the traction control, smooth out the throttle, and switch off the anti-wheelie for rear wheel antics.
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.
MOTORCYCLE TRACTION CONTROL
Motorcycle Traction Control is a mouthful, but it's an important part of the KTM 790 DUKE. MTC is a lean-angle sensitive traction control system, which reduces engine output extremely smooth, barely perceptible. Depending on the selected ride mode, MTC also allows for several levels of traction slip at the rear wheel. But that's not the end of it - Daredevils, we give you: the off-switch!
Ergonomics
The KTM 790 DUKE is an aggressive motorcycle with easy rider ergonomics. This is the key to its long-standing success. A narrow chassis and engine, comfortable seat height, upright seating position, and spacious legroom don't sacrifice cornering clearance on the street, while the footpegs allow for extreme lean angles when cutting into the canyons.
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.
Seat
At 825 mm, both shorter and taller riders can enjoy the bike at full tilt, without losing sight of the daily usability. The seat cover is grippy but still allows the rider to move around the bike easily. It has been developed to work with textile and leather, in keeping with the wide range of riders and riding styles. The pillion seat cover uses the same material and combines sharp looks with passenger comfort. 805 mm is possible with the lower KTM PowerParts seat.
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.
Footpegs
Cast from aluminum, the foot pegs fitted to the KTM 790 DUKE cater to a comfortable riding position, while still creating maximum ground clearance allowing for impressive lean angles. Adjustable foot pegs are also available as a KTM PowerParts option for those who would like to go all out.
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.
Frame
The incredible handling characteristics of the KTM 790 DUKE are founded on the dynamic, loadbearing design of the tubular chassis. Engineers had one goal in mind, and that was to keep the chassis as rigid and compact as possible for sharper turn-in and greater lean angles, allowing it to slice through the turns with extreme responsiveness.
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.
Swingarm
The die-cast, open-lattice swingarm is meticulously manufactured and has been optimized for stiffness and stability while still offering excellent flex characteristics. By using a direct link for the rear shock, complexity and parts are reduced.
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.
Fork
A 43 mm open cartridge upside-down front fork from WP Suspension takes care of any front wheel articulation, using split function technology. This means that compression and rebound damping take place in separate fork legs, allowing for better tuning of the fork behavior. The fork springs are progressive, ensuring a smooth operation throughout the fork stroke, being softer for the initial stroke, and harder further down the stroke to prevent bottoming out.
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.
Rear Shock
Making sure the rear wheel behaves when the going gets fast, is a high-quality gas-assisted WP APEX rear shock, featuring progressive spring and preload adjustment. This means the KTM 790 DUKE maintains a sporty ride quality, while still being comfortable enough for longer trips.
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.
Wheels and Tires
The KTM 790 DUKE is fitted with extremely lightweight, light-alloy wheels manufactured using a low-pressure die-casting process. Not only do the lightweight wheels subtract from the overall weight, but they also minimize the unsprung rotating masses and are wrapped in a set of MAXXIS Supermaxx ST tires.
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.
Brakes
Maximum deceleration is ensured at the front wheel on the KTM 790 DUKE by the two radially mounted four-piston fixed calipers and two 300 mm discs. The spacing between front brake lever and handlebar is adjustable so that the lever is within easy reach for every rider. The front brake receives effective support from the disc brake on the rear wheel, which features a single disc and a single piston floating caliper.
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.
