2025 KTM 390 Duke: Key Things To Know
If you dig the KTM 390 Duke, we have some good news for you. The popular naked has been updated for 2025, and it’s become even more feature-packed. This isn’t an overhaul by any measure, since that happened back in 2023. Instead, it’s more of a refinement of what’s already an impeccable package. Here are three key things you should know.
New Features Elevate The 2025 390 Duke’s Package
The 390 Duke is one of the most loaded naked bikes in the sub-500cc segment. And things have gotten better in 2025. Cruise control is the new addition here, which is accessed via a dedicated button on the left-side switchgear. When engaged, you can use a ‘+’ and ‘-‘ buttons to increase or decrease the set speed. This system is the same as the one seen on the 390 Adventure R.
Aside this, all other features are carried on. A five-inch TFT sits as the centerpiece, giving you access to smartphone connectivity and modern electronic aids. The latter includes:
- Traction control
- Launch control
- Ride modes
- Cornering ABS
- Two-directional quickshifter
The Punchy 399cc, Single-Cylinder Engine Powers The 2025 390 Duke
Under the skin, the 399cc, single-cylinder engine serves duty on the 2025 390 Duke. It is good for 44.2 horsepower and 28.8 pound-feet, all of which reaches via a six-speed transmission. That is not only one of the highest numbers in the segment, but also enough to propel you to 62mph in under 5.5 seconds from a standstill. Having ridden one, GoodBikeBadBike.com can confirm it’s something both new and experienced riders will dig.
Adjustable Suspension Ensures The 2025 390 Duke Is Fun To Ride
Finally, the 390 Duke is built around a trellis frame. This works in tandem with an aluminum subframe and swingarm, while WP suspension helps absorb all the undulations. The 43 mm USD forks and the monoshock both offer adjustability to enable fine-tuning deepening on your riding style. All this while, you get 17-inch alloy wheels, each of which wears a single disc brake with ByBre calipers. The result is a curb weight of ~370 pounds.
