Chassis and Handling

The KTM 390 Duke 2025 is the new generation of one of the most popular naked bikes in the mid-range class. It is designed for the city, but is not afraid of fast roads and sharp turns. In this category, we will take a detailed look at the chassis and handling, as these are what shape the character of the motorcycle.

Frame

The motorcycle has a new steel trellis frame with a cast aluminium subframe.

• This design makes the bike lighter and stiffer.
• The stiff frame provides more stability at speed.
• The lightweight aluminium subframe reduces the weight of the rear end.

When riding, the motorcycle behaves precisely and predictably, even when changing direction sharply. This is an advantage in urban conditions: it is easier to manoeuvre in heavy traffic.

Suspension

At the front is a 43 mm WP APEX USD fork with an open cartridge. It has rebound and compression adjustment.

At the rear is a WP APEX monoshock with a progressive lever, also with adjustment.

Thanks to this:

• The suspension smoothly smooths out bumps in the city.
• It remains stiff and does not sway in fast corners.
• The adjustments allow you to tailor the bike to your riding style.

The suspension will be comfortable for beginners, while experienced riders will be able to make precise adjustments for track or freestyle riding.

Brakes

A single-disc braking system with a four-piston radial ByBre caliper is used at the front. At the rear, there is a single-disc brake with a single-piston caliper. The system is supported by Bosch 9.3 MP ABS with Supermoto mode.

This means:

• In the city, the brakes are precise and reliable.
• On the track, you can turn off the ABS on the rear wheel for more control.
• The Supermoto system is suitable for riders who enjoy an active riding style.

Wheels and tyres

The motorcycle has 17-inch alloy wheels.

Tyre sizes:

• Front tyre — 110/70 R17
• Rear tyre — 150/60 R17.

This is standard for the class, but it is important that the tyres are easy to find and offer a good balance between grip and durability.

Geometry

Key parameters:

• Seat height: 820 mm.
• Ground clearance: 183 mm.
• Wheelbase: 1357 mm.
• Weight (without fuel): 165 kg.

What does this mean for the rider?

• The low weight makes the bike accessible even to beginners.
• The wheelbase is slightly shorter, which adds manoeuvrability in the city.
• The seat height is average — suitable for most riders taller than 170 cm.

Handling in the city

The bike feels very light and precise in traffic.

• The wide handlebars provide good control.
• The light weight and narrow silhouette help you weave between cars.
• The suspension comfortably handles potholes and kerbs.

Riders will find that the KTM 390 Duke is an urban iron horse that easily conquers any traffic jam.

Handling on the track

On the open road, the motorcycle shows a different character.

• The rigid frame and tuned suspension allow you to take corners aggressively.
• ABS in Supermoto mode makes braking more sporty.
• The low weight gives the feeling that the bike can be leaned as low as possible.

It's a real little sports bike in a naked body. The 390 Duke delivers the same thrills as the larger KTM models, but in a more accessible format.

The chassis and handling of the KTM 390 Duke 2025 are the main reasons why this motorcycle is so highly regarded.

• The new frame provides stability and lightness.
• WP suspension makes the ride versatile: comfortable in the city, controlled on the track.
• Supermoto ABS brakes open the door to a sporty style.
• Light weight and comfortable geometry make the bike accessible even for beginners.

If you are looking for a motorcycle that feels equally at home in the city and on the motorway, the 390 Duke 2025 is the right choice.

KTM 390 Duke Electronics & Safety

The new KTM 390 Duke (2025) has undergone significant changes in terms of electronics and safety, making this bike modern and technologically advanced. From the very first moments, it is clear that the manufacturer sought to create a motorcycle that combines ease of handling with advanced rider assistance features.

The most important element is the Ride-by-Wire system, which ensures precise and predictable throttle response. Thanks to this technology, the bike quickly adapts to commands, increasing comfort and control. In addition, the electronics allow the system to work with different riding modes, making it possible to change the character of the motorcycle depending on road conditions.

It should be emphasised that Cornering ABS is a key safety system in this generation. It allows you to maintain stability even when braking on corners. It works in conjunction with Supermoto ABS, which is activated on the rear wheel and allows for a more dynamic riding style. This makes the bike versatile and suitable for both city and active riding.

Another important feature is Quickshifter+, which allows you to shift gears without using the clutch. This system works in conjunction with electronic engine management to make your ride smoother and faster. As a result, the rider gains more precise control and reduces fatigue during long journeys.

The new TFT display, which is now larger and brighter, deserves special attention. It not only displays basic information, but also allows you to connect your smartphone. This makes controlling music or calls easier and safer. The display integrates with the motorcycle's electronics and functions as a modern control centre.

So, the KTM 390 Duke (2025) demonstrates that even in the mid-range class, it is possible to use solutions that until recently were only found in top-of-the-range models. Its electronics and safety system not only makes riding safer, but also adds a feeling of real control, which is particularly appreciated among young motorcyclists. All this confirms that the new Duke is a motorcycle that combines style and modern technology at the highest level.

ENGINE SPECIFICATIONS & TRANSMISSION SYSTEM

The new KTM 390 Duke (2025) has undergone extensive modernisation in terms of its engine and transmission. This makes it more efficient and suitable for different riding styles. KTM's designers focused on precision, performance and reliability, creating a power unit that combines compactness and high technology.

Firstly, the engine has a displacement of 399 cubic centimetres and is designed as a single-cylinder block with liquid cooling. It has a new architecture that reduces weight and improves balance. Thanks to an improved combustion chamber, fuel efficiency has been increased. In addition, the new piston and cylinder design allows for greater stability at high revs.

Particular attention should be paid to the maximum power of 44 horsepower, which has been retained in the A2 class. This makes the motorcycle ideal for beginners, but at the same time dynamic enough for experienced motorcyclists. In addition, the torque has been optimised for urban conditions and mixed routes, where quick response and confident acceleration are required.

In addition, the engine works in conjunction with a modern Ride-by-Wire system, which ensures precise throttle response. This means that every movement of the throttle lever is converted into a controlled and smooth action. This system helps to realise the full potential of the engine and makes handling predictable even for less experienced riders.

TRANSMISSION SYSTEM

Now let's move on to the transmission. The six-speed gearbox has been refined for better shift clarity. Each gear now has a more precise gear ratio, making the motorcycle more versatile. Optimised first and second gears are used for city driving, providing quick response. Meanwhile, fifth and sixth gears allow you to save fuel at a steady speed on the motorway.

Equally important, the transmission supports Quickshifter+, which allows you to shift gears without using the clutch. This makes riding more dynamic and reduces driver fatigue. Thanks to the electronics, shifting is smooth even under load, emphasising the Duke's sporty character.

Another detail is the PASC anti-slip clutch, which comes as standard. It prevents the rear wheel from locking during sudden downshifts. This solution significantly improves safety when cornering and gives you more control in difficult situations.

Together with the lightweight engine, the transmission creates a feeling of true balance between power and control. KTM has done everything to ensure that even after many hours of riding, the engine and gearbox remain stable and predictable.

Ultimately, the KTM 390 Duke (2025) demonstrates that even in the compact naked bike class, complex technological solutions can be implemented. Its engine and transmission work as one, ensuring reliability and riding pleasure. This is a case where technology creates a feeling of lightness, speed and complete control.

FUEL CONSUMPTION

Understanding the fuel consumption of this manoeuvrable motorcycle is very important. From the outset, motorcyclists have noted its balance between power and economy. According to official data, fuel consumption is around 4.7 litres per 100 km, which corresponds to approximately 50 miles per gallon according to the American standard.

This is quite efficient for a 399 cc streetfighter.

What's more, motorcyclists report 30 km per litre in everyday conditions, which seems plausible.

This shows that a motorcycle can be both sporty and economical. Thus, despite its powerful performance, it remains surprisingly economical.

Practically speaking, with a 15-litre tank, motorcyclists can expect a range of around 450 km on a single tank before refuelling.

This means fewer stops and more time on the road.

Fuel economy is one of this motorcycle's strengths. It delivers high efficiency and exciting performance at the same time. You get economy and enjoyment in one elegant package.

PRICING

The KTM 390 Duke 2025 is an affordable entry into the world of modern sports naked bikes. It combines style, technology and a relatively low price. But the price is not the same for all markets. It varies from country to country, and that is what makes pricing an interesting topic.

In most EU countries, a motorbike costs around €6,000–6,500. The price depends on the VAT rate, which is 19% in Germany and 20% in France. Therefore, even within the same continent, the difference can be significant.

On the American market, the price usually starts at around $5,900–6,200. It is important to note that in the United States, the price is almost always quoted without taxes. The final amount depends on the specific state, as tax rates vary.

In India, the 390 Duke has the most affordable price, as it is manufactured at the Bajaj factory there. The cost starts at around $3,000–3,200. This makes the model one of the most popular in its class on the Asian market.

In the United Kingdom, the price ranges from £6,000 to £6,200, which is more expensive due to local taxes. In Australia, the motorcycle costs around AU$7,000, and in Canada, approximately CA$6,500.

Knowing global prices helps to understand that the 390 Duke is positioned as an affordable premium naked bike. It is not the cheapest in its class, but it offers technology that is usually found in more expensive models.

Although prices vary from country to country, the 390 Duke retains its reputation as the most affordable choice among mid-range sports naked bikes.

RIDING IMPRESSIONS

The KTM 390 Duke 2025 leaves a strong impression from the very first minutes behind the wheel. The motorcycle looks modern, but most importantly, it gives you a feeling of control and drive. Its character is shaped not only by the engine, but also by how it behaves on the road. That is why the overall riding experience is so important for evaluating this naked bike.

Position and ergonomics

Riders will immediately notice that the seat is quite high. However, the 820 mm seat height is still suitable for most people of average height.

On daily trips, the bike feels like a ‘motorcyclist's partner’ that can easily handle any task. For longer trips, wind protection may be lacking, but this is to be expected for a naked bike, so it is not a major drawback.

The thrill of riding

The main impression of the 390 Duke is the thrill it gives you. The bike makes you smile even in everyday traffic. Its lightness and responsiveness create a feeling of playing with the road. In the city, it helps you manoeuvre quickly, and on the track, it gives you a sporty feel. This combination makes it special among its competitors.

The overall impression of riding the KTM 390 Duke 2025 can be described as a combination of lightness, stability and excitement.
