presentation of the 790 Duke 2025

The 790 Duke initially looked with suspicion at the arrival of the 990. More watts, more technology... and a lot more euros to ride it. As a result, it is less worried about its place in the range and is being reinvigorated for 2025. On the menu, Euro5+ approval, an extended rear mudguard, a slightly sharper headlight, a new dashboard whose position is closer to the rider, a new interface, automatic adaptation to ambient light, a telemetry screen, 6-level wheelie control, and DEMO Mode, allowing you to sample all the electronic options of the bike for a good thousand KM. After that, you have to pay or say goodbye.

The 790 Duke has a two-stage career. Born at the end of 2017, it was weighed down by the 890 in 2021..... then waited a while..... and returned to the market in mid-2022.
KTM has put it back on the market with new arguments, but... what are they? How do you make a place for yourself when you've got the same face, the same physique, the same technology and the same audience........... with less displacement and power?

That's the problem, and the solution in the same pot. The 790 Duke as we've rediscovered it is a continuation of the old L version, designed for A2 license holders. Apart from an extra 8 kilos and adaptation to Euro5, it differs little from the first model, except that it is now produced in China. This is one of the fruits of the partnership with CF Moto.
From here, it's easy to see why it's back in the Katoche Naked range. Powerful, the machine offers 105 hp in most parts of the world, except in Europe, where its hara is reduced to 95 hp. With this level of power, it forms a sort of bridge between the 390and the 890.

KTM 790 Duke 2025 - 1KTM 790 Duke 2025 - 1

Not quite the middle ground. There's a 51-horsepower gap between the little Dukeand the 790, while the latter gives back only 10 hp to its "big" sister. So it's hardly a beginner's bike, except when limited to 35 kW.
Which raises another question. The 890 was also available in an L version, suitable for any castration required. So is the spectre back? Why?

Because the 890 L has disappeared from the catalog. A sort of game of musical chairs, punctuated by a shock argument: the price! Between the two roadsters, the match will be played on watts, but also on the big difference in price. A difference of almost 2,000 euros - in exchange for a fuller engine and less rigorous suspension. These aren't foam legs, either. It's just that the first 790 Duke didn't offer as much rigor as we'd hoped. The bike incited attack, virulent and motivated, fun and angry; but the suspension could barely keep up.

KTM 790 Duke - Moteur so , what does this Duke 790 "revival" offer? A 43 mm WP upside-down fork with no adjustment - the 890 doesn't do any better, but the settings are different - a WP shock absorber with preload adjustment, 4-piston radial calipers around 300 mm discs, the inflexible tubular steel frame and well-weighed electronics. Also included are an inertial unit, cornering ABS + Supermoto function, 3 riding modes (Rain - Street - Sport), angle-sensitive traction control, LEDs everywhere and a 5" color TFT screen. As for the shifter, there's no change: you'll have to find it in the options section.

A Race riding mode, engine braking control, cruise control, KTM My Ride smartphone app and tire pressure monitoring are also waiting in the wings, while the Powerparts section offers a whole host of parts.

So, the 790 Duke wants to make a name for itself in the big poker game played by mid-size streetfighters. It's no easy task, given all the hotshots already on the scene and the snarling atmosphere of the sector. But with its price tag, it's a sobering one - almost identical to that of a 750 Hornet, a 660 Trident or an F 900 R.
Be that as it may, the 790 and 890 won't be buddies for long at the KTM table. Two sisters, two hearts, on the verge of resentment.

French Lololetzgo Model 2024
I have a 2023 KTM 790 Duke and I'd like to come back to its range and top speed. As far as range is concerned, I only do slightly more than 250 km on a full tank (to solve the weight problem, I changed the exhaust). As for the top speed, I easily reach 213 km/h in fifth gear, then 230 km/h in 6th gear. Don't hesitate to tell me what your range is with this bike and your top speed (V motard) Rating : 4/5

Obsession des couleurs de motos imposées
French velo cargo Model 2023
the only KTM offered in grey (or almost...) is the only one I might buy, because Ktm's orange drips to overdose on the other models, with no possible alternatives: but losing customers (like me) doesn't seem to be a problem for them... too bad, because the lines and performance of the more powerful roadsters aren't bad at all.

Hello
The return of the 790 (Duke and Adventure) at a knock-down price is simple, the 790 is made in China since 2021 in the new factory built in partnership with CF Moto, while the 890s are made in Austria, a big delta on the cost price....I'm going to replace my 30,000km 790 Adventure (no shit) with the new 890
It also allows KTM to do away with the 890 L (A2 adjustable)

Okay, so the 790 is back at the same price as before, but everything that made it a bike that stood out from the competition (and ultimately provided good value for money) is now optional. So we might as well buy second-hand. KTM's marketing department really takes its customers for cows... Rating : 5/5
fantastique
French beuleuveu Model 2018
i've owned a Duchess since it was first launched, and after 11,000 km and 1.5 years, I'm absolutely won over. Yes, the suspensions aren't top-notch (I've just had an EMC sport shock 2 fitted) and the reliability problems inherent in a brand-new block are there #essuyagedeplatreenrègle. But the rest is a marvel. The chassis is light, agile and fun. Rage and punch for the engine. It's pure KTM, and the only bike I've ever ridden that could get me off my street triple. Rating : 5/5
Problèmes récurrents
French vilto Model 2018
I have registered on several 790 duke and MT 07 forums and facebook groups. On the KTM side, we see these problems EVERY day on our bikes:

- Low-engine oil leaks
- Recurrent cold stalls
- Error messages
- Problems after maintenance and map update

On the MT 07 side ?? CLEAR!

So ok the MT 07 isn't popular in terms of image, but Yamaha is RELIABLE ;)

It breaks my heart because I love the look and ride of the 790 duke, but my reason makes me choose the one I like least in twin-cylinder form...

hello
I've owned this bike since it came out (April 2018) and I've only had one problem since it came out. I solved this problem by changing the front cartridge and the rear element, which I have done on every bike I have owned.There have also been a few leaks which have all been taken under warranty by ktm. This bike's strong points: agility and roadholding, racy engine character, ridiculously low fuel consumption and high-performance electronics.

French kiki03 Model 2018
honda for 30 years i bought 2 ktm in july 2018.
790 duke for 2-up riding and 1290r for solo riding.
the 790 on july 15 was about 9700â'¬, i changed the original tires for M7RR.
this bike is brilliant, amazingly easy to handle, and the shifter is just crazy.
in 2006, i was riding a zx9r, which is zero compared to the 790, and we're not talking about the superduke 1290r ....

It's amazing that it's people who don't own a 790 who give it bad marks. This little bike is a real treat, with no major faults. Very well equipped from the outset, it's a real treat on the road, as well as on the track. Rating : 5/5
French vince Model 2018
as the owner of a 790 duke l (a2), i find the fuel consumption very high, on the first 1000 kms it overconsumed the oil, now it's better for the oil, the 47.5 hp clamping is pretty good,the rear maxxis tire offers good grip but very limited longevity (4000 kms and already sanded), otherwise the bike is very manoeuvrable and slips along all by itself, the noise from the original pot is top-notch (no need to invest in 800-euro pots), the electronic assistance is there when it's needed and not too intrusive - I have a shifter fault on 6th gear to watch out for, the suspension does its job very well on my country roads, which are completely potholed despite the critics!it's a very reassuring bike, even a little too trusting for my taste, or rather that of the police!

Moto super fun mais fiabilité à revoir ?
French Nouba Model 2018
Motorcycle tested and to ride nothing to say, it suited me perfectly, I hesitated with another motorcycle, after having followed some forum or pages dedicated to this 790 where regularly I could read problems of oil leaks, I chose the other motorcycle and now after a few months where I continued to follow discussions, I do not regret my choice, the bad returns are too numerous for me !

Rating : 5/5
French Bapts Model 2018
Perplexed... okay, it's fun, well equipped, although it lacks front brake bite and rigorous damping.
The engine... I don't know if it's the design or the gearbox ratios, but there's not much at the bottom and it suddenly starts to rev in the middle of the rev count... cool, you might say... except that the rev limiter suddenly arrives and cuts off your smile at barely 2000 revs higher! Ahhh frustration!!! Barely enough time to put the handle in the corner to shift up! It's a good thing the shifter works wonders...
As for agility, there's nothing to say, it's easier to handle than my street bike, probably thanks to the more natural, supermot-like riding position.
In the end, I didn't sign up for it. Despite my desire for a bike that's more fun and more livable than the street, which pulls long and pushes you to ride too hard to have fun, this one pulls really (too?) short. I'm waiting to see the R version of the big sister and its price tag, if it arrives soon.
