presentation of the 390 Duke 2018
Once you've whetted your appetite for two-wheelers with the 125, the 390 Duke is there to follow up and introduce you to the joys of an intermediate-displacement bike. For this second edition, the roadster's arguments are on the rise. KTM insists on cultivating a family identity, except that this time, the Duke has brought out the big fangs.
with the first line of small Dukes(125, 200 and 390), Mattighofen offered them the vision of the 690. In other words, the roadster that took the single-cylinder motorization to an excellent fun/sport/performance level. But now, the new generation is aiming higher, meaner and bolder. And what's more violent than Katoche?! The 1290 Superduke R. THE sick machine, with a twin that uproots molars.
So, like the 125, the 390 Duke has opted for a design closely modelled on the big Superduke. The result is a real success story. With its visible spine, incisive face and taut lines, the bike's design constantly oscillates between the toughness of a Superduke and the playfulness of a toy. But make no mistake. The desire to have fun, of course, but in the manner of a little buccaneer.
in addition to a design that appeals to the young and the stylish, the KTM has also evolved to more quickly intercept A2 licenses. A tactical weight gain of 10 kilos enables it to comply with legislation - the old model was too light and had to restrict its engine. The 390 Duke now weighs 149 kilos (10 more). The extra weight is mainly due to the exhaust and fuel tank. The latter has gained 2.4 liters in capacity. Does Mademoiselle Orange mind this extra weight? No, it doesn't really matter, as it's still one of the lightest bikes in its class.
True to its mono design, KTM has made only minor alterations to its engine. This gives it a little more flexibility and reduces emissions to comply with Euro4 standards. The power output remains unchanged, peaking at 44 hp, but 500 rpm earlier, at 9,000 rpm. As a bonus, a pinch of torque has been added (2 Nm).

kTM has also thought about suspension, with a new fork, still inverted with a diameter of 43 mm, but lighter and more efficient. As for the frame, there are no changes to report. The tubular trellis provides the satisfaction and versatility required. Let's not forget the addition of adjustable levers, an anti-dribble clutch and new saddles offering a little more space. For the passenger, however, the welcome remains on the verge of courtesy.
a very successful redesign for the KTM 390 Duke. Its predecessor had already attracted more than just the curious to the A2 class, but this is a full-scale seduction operation. The days of the 250/300 are over, and we're witnessing the rise of the 400. Is this enough to trigger a boom in the sector? Maybe not, but it's sure to give you a real buzz.

Bikers' reviews Leave a review - 6 reviews
Left fork spinnaker seal dead at 2,000km! (it can happen) and the two original ContiMotion changed around 4,000 (at the wear indicator), for the rear I'm blasé, 2016-2021 same fight, the bug eats rubber!... for the front I was used to making the double last but well, this 2021 brakes very hard, I'm not going to spit in the soup!
For those who knew the 2013-2016 model, this new version is still fun, very fun, but more "civilized" because of the standards, the engine character has mellowed quite a bit, despite 10kg more, it's still one of the most playful bikes and has no real rivals in the A2 category because it's unbridled, to get some pep I strongly recommend a 14-tooth gearbox output sprocket, it's true that you don't go as fast at the top, but what does that matter?..
As for petrol consumption, it's around 4L/100 if you're respectful (mechanically and otherwise) in a straight line. With a 13.5L fuel tank, you can be sure of a 220km range
If I'm ready to take one back? of course, but before the warranty expires! Rating : 4/5 Respond to jeanmarc
I can't recommend it enough! Rating : 5/5 Respond to Siyan
