KTM 790 DUKE 2019



The KTM 790 DUKE is devastatingly accurate. The agility you’d expect from a single, blended with the meaty punch of a twin. It carves corners with pinpoint precision, boasting the all-new 799 cc LC8c parallel twin motor nestled into one of the lightest and most compact chassis around. The KTM 790 DUKE is all about being fast where it counts – in the corners. Dynamically flicking from one bend to the next, putting you in the heart of the action and not on the sidelines.

We present KTMs first parallel twin engine: the LC8c. The ‚c‘ stands for compact, ‚LC8‘ for the fun awaiting you.


Instead of the electronic injection system’s throttle valves being controlled by cables, ride by wire generally processes throttle twist grip movements with the help of electronic sensors and activates the throttle valves accordingly using servo motors. However, our ride by wire on the KTM 790 DUKE goes the extra mile: It electronically translates the throttle […]


Forged pistons with three piston rings in a plain conrod bearing, combined with a DLC (Diamond Like Coating) coated piston pin allow for lighter pistons. This minimizes reciprocating weight, which reduces rotating masses, improving the handling and maximizing the rev-happy nature of the engine.


Not only does this pressure lubricated slipper clutch open when the engine back-torque becomes too high, it also assists when you open up the throttle. The former prevents destabilizing rear wheel chatter when braking sharply or decelerating; the latter reduces the hand force required for changing gear, allowing the clutch to be controlled with one […]


The engine employs a compact, semi-dry sump system. Oil is actively pumped out of the crank case, clutch housing, and gearbox. This ensures that it does not unnecessarily flow through the engine, reducing power loss through friction. To cool down the oil, the engine is equipped with an oil cooler similar to the larger LC8 […]


A stainless steel thing of beauty. The middle damper centralizes mass and allows for a relatively small muffler that plays a dramatic soundtrack to possibly huge lean angles. Hundreds of test bench runs and complex simulations ensured that this exhaust system contributes decisively to the tractable torque curve and excellent emission values.


Built for torque, this liquid cooled 8 valve unit delivers 87 Nm at 8000 rpm, almost immediately followed by a roaring 105 hp finale. Meanwhile, an advanced ride-by-wire system guarantees great refinement as well as low fuel consumption and emission figures.


The coated aluminium cylinders are an integral part of the sleeveless engine casing. The open deck cylinder construction allows for optimal cooling and improved production tolerances.



The horizontally split crankcases (a first for KTM) are an aluminium high pressure cast, which allows for reduced wall thickness and, again, less weight.


Vibrations are taken care of by two balancer shafts, one in front of the crankshaft and the other in the cylinder head between the two camshafts. Smooth move.


The airbox sits snugly inside the subframe, with the air intake on the sides, allowing the bike to keep things cool while you gun it.



The KTM 790 DUKE’s incredible handling characteristics is founded on the dynamic, loadbearing design of the chassis. A large part of its agility comes from an all-new lightweight frame package, utilizing the engine as a central handling element. The chromoly steel frame also features an innovative cast aluminum subframe, keeping the chassis rigid and compact for sharper turn-in and greater lean angles, allowing it to slice through the turns with extreme responsiveness.


The tubeless sport tires are fitted on extremely lightweight, light-alloy wheels manufactured in a low-pressure die casting process. Not only do the lightweight wheels make the bike lighter overall, they also minimize the unsprung masses and moment of inertia, with a positive impact on the handling and ride dynamics.


The cast aluminium triple clamp stiffness has been tuned to match the flex of the fork, contributing to the sporty handling and excellent feedback. By cleverly engineering the triple clamps and the handlebar clamps, four different handlebar positions are possible.


The 790 DUKE is fitted with Maxxis Supermaxx ST tires in a special compound developed specifically for the bike. The tires are grippy in both wet and dry conditions and strike a balance between sportiness and everyday rideability. The sporty character of these tires fits the 790 DUKE, while offering the rider a stable ride […]


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.


The subframe is cast aluminum and houses the airbox. No plastic covers, no additional brackets – everything is cast in one single piece to reduce complexity and weight. The triangular shapes in the subframe were inspired by KTM’s trellis subframes, as this allows for a strong and simple construction.


This reliable and sensitive WP steering damper has been setup to give the rider a secure feeling, while keeping the agile riding character of the bike. You won’t even know it’s there, until that one nasty bit of road comes up from behind the corner.


State-of-the-art, gas assisted WP shock with progressive spring and preload adjustment.


The 43mm open cartridge upside-down fork from WP Suspension provides you with a suspension set-up that’s unseen in this segment. The fork uses split function technology, which means that compression and rebound damping take place in separate fork legs, allowing for better tuning of the fork behaviour. The fork springs are progressive, ensuring a smooth […]


When designers and engineers can start from a blank canvas, beauty meets performance. Take this chrome-molybdenum tubular frame, which makes a major contribution to the bike’s excellent chassis geometry, for example. It’s a laser-cut, robot-welded thing of beauty with a glorious surface finish. And it can count on the engine as a load bearing element, […]


Maximum deceleration is ensured at the front wheel on the KTM 790 DUKE by the two radially mounted four-piston fixed calipers with 300 mm twin-disc brake and a radial hand pump. The spacing between hand brake lever and handlebar is adjustable so that the lever is within easy reach for every rider. The front brake […]

Designed to deliver confidence-inspiring control that suits all riders. The KTM 790 DUKE features 4-way adjustable handlebars, a race-inspired seating position and high-set foot pegs, perfectly suited for more aggressive riding styles.


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 […]


A tapered aluminium, 760 mm wide handlebar puts you in full control. It’s adjustable in 4 positions on the triple clamp and can be rotated in three further positions.


The cast aluminium footrests cater to a comfortable riding position, while still creating maximum ground clearance to allow for a high lean angle. Reverse (race) shifting is possible without any additional parts. Adjustable footrests are available as a POWERPARTS option for those who would like go all out.

The hunkered down aggressive stance of the new KTM 790 DUKE is intimidating to all who cross its path. It clearly takes some of its design cues from the 1290 SUPER DUKE R – most obvious being the unique LED headlight cluster. The distinctive sharp lines and compact 11/13 proportions are set off by signature KTM orange graphics, leaving no doubt as to its pure road-dominating intentions.


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.


Form and function are seamlessly integrated in the 790 DUKE. Take the LED headlight for example, a highlight in this bike’s design and a clear referral to the 1290 SUPER DUKE R. It combines optimal illumination of the near field with maximum light output. And the daytime running lights on both sides ensure that the […]

The KTM 790 DUKE comes with some serious brainpower as standard. Riders can choose from four ride modes, namely Sport for more aggressive riding, Street for urban riding, Rain for when things get a little slippery and, the ultimate attack mode called Track. This awards KTM 790 DUKE pilots with full power output, Launch Control, increased throttle response and the ability to disengage the anti-wheelie function for rear-wheel antics. Even when you’re flirting with the limit, KTM’s combination of the most advanced software and electronics in the world of motorcycling will have your back. All you have to do is focus on the road ahead – and hold on tight.


Track mode offers unlimited thrills. It features launch control, slip adjuster, free choice of throttle response control and allows you to pull epic wheelies. » Anti-wheelie: Anti-wheelie is a sub function of the traction control aimed at always keeping the front wheel on the ground. But on a track it can be desirable to allow […]


The fun-loving Supermoto mode allows the rider to block the rear wheel – a prerequisite for committed Supermoto riding and deliberately executed slides. The ABS function remains active on the front wheel, even in this mode.


Ride modes regulate the performance output and the ‘character’ of the motorcycle according to riders’ preference. The riders’ throttle commands are electronically translated into throttle valve positions perfectly suited to the riding conditions. The various ride modes control several things at the same time, while the Track mode allows the rider to adjust individual settings […]


The KTM 790 DUKE comes equipped with a Quickshifter + that allows slick, clutchless up- and downshifts under any load. It reads and responds to your riding, so the shift action is fast when you are, but buttery smooth at half-throttle. When downshifting, the system matches the engine speed to the speed of the lower […]


The Motorcycle Traction Control (MTC), a lean-angle sensitive traction control system, reacts immediately if the rotational speed of the rear wheel is disproportionate to the riding situation. In a matter of milliseconds, MTC reduces the engine output with an extremely smooth, barely perceptible intervention at the throttle valves, until the system has reduced slippage to […]


The ultimate in safe deceleration: one component of the comprehensive Bosch MSC assistance package is the lean-sensitive cornering ABS. Based on the high-quality 9.1MP modulator, it unites the talents of combined braking and lightning-quick, efficient pressure modulation with the high quality brake components to make the most advanced braking system on the market – no-one […]


The 790 DUKE is equipped with standard MSR (Motor Slip Regulation), which is an engine brake control that works in the opposite direction of the MTC. If, due to shifting down or abrupt throttle-off, the engine drag torque is too high, the ride-by-wire system balances the throttle exactly as much as is needed to ensure […]
