The 2025 iteration brings even more sophistication to an already impressive package, making it an irresistible proposition for riders seeking the ultimate naked bike experience.
Evolution of a Legend: The Duke Dynasty
The Duke nameplate has been synonymous with KTM’s street dominance for over three decades, and the 390 Duke represents the culmination of this rich heritage. Launched as part of the Gen-3 Duke range, the current 390 Duke boasts dramatically improved cornering behavior, stability, and handling proficiency thanks to a new, slightly longer wheelbase, new seat height, and new frame geometry. This evolution ensures that every twist of the throttle delivers an exhilarating experience that honors the Duke tradition while embracing modern technological advancements.
The relationship between the 390 Duke and its larger siblings is unmistakable, creating more of a direct lineage between the 390 and its 1390 bigger brother than almost anything else on the market. This design philosophy ensures that riders experience authentic Duke DNA regardless of engine displacement, making the 390 an ideal stepping stone for those aspiring to join the Duke family.
Heart of the Beast: Engine and Performance
At the core of the KTM 390 Duke lies the latest generation LC4c engine, with the gen-3 KTM 390 Duke muscling up with a larger 399cc capacity, more power, smoother acceleration, and lighter overall weight than before. This single-cylinder, liquid-cooled powerplant delivers 46 PS of power and 39 Nm of torque, providing an impressive power-to-weight ratio that makes every acceleration feel explosive.
The engine’s character has been refined to offer smooth power delivery while maintaining the aggressive nature that Duke enthusiasts expect. 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. This performance capability positions the 390 Duke as a serious contender against much larger displacement motorcycles.
The engineering excellence extends to the motorcycle’s weight distribution, with the exhaust now underbelly, which allows the center of mass to be more balanced. This optimization contributes significantly to the bike’s exceptional handling characteristics and overall stability during aggressive riding.
Cutting-Edge Technology and Features
The 2025 KTM 390 Duke represents a technological tour de force, packed with features typically found on motorcycles costing significantly more. As part of the 2025 update, KTM has given the 2025 390 Duke cruise control. This feature made its debut on the 2025 KTM 390 Adventure which was launched earlier. This addition transforms the Duke from a pure urban weapon into a capable long-distance tourer.
The centerpiece of the technological arsenal is an all-new 5″ bonded glass TFT dashboard with new switch cube, 4-way menu switches that allow easy interaction with all vehicle functions. This display provides smartphone connectivity, enabling riders to access turn-by-turn navigation, call and SMS alerts, and music control functions seamlessly.
Advanced Rider Aids
The 390 Duke’s electronic suite includes multiple riding modes designed to optimize performance for various conditions. The Gen-3 KTM 390 Duke gives its pilots a selection of RIDE Modes to best suit whatever conditions they find themselves in – STREET Mode activated as standard unleashes all the KTM 390 Duke’s fury, while RAIN Mode works to keep things a little more controlled in the wet.
The addition of Track Mode introduces a new dimension to the riding experience. Track Screen transforms the 5″ TFT display graphics to be more race-focused, enlarging the rev counter, showing the laptimer, selected gear display, reduces the size of the speed readout, and shows preferred rider aid settings. TRACK Mode also allows riders to initiate Launch Control.
Launch Control: Racing Technology for the Streets
One of the most exciting additions to the 2025 model is the inclusion of launch control, a feature typically reserved for high-end superbikes. With TRACK Mode selected and Launch Control engaged, the engine will peak at 7,000 rpm with a wide open throttle, waiting for the rider to release the clutch. This system ensures perfect launches every time, whether at traffic lights or on the track.
Design Philosophy: Aggressive Meets Functional
The 390 Duke’s design language draws heavily from KTM’s flagship Super Duke models, creating a visual continuity across the Duke range. KTM decided on the design by taking out the files of the 1290 Super Duke and tracing them onto the 390 Duke. The motorcycle now looks more like a replica of the iconic Super Duke than ever before.
Key design elements include the aggressive LED headlight with distinctive boomerang-shaped DRLs, extended tank shrouds that create a muscular profile, and an exposed rear subframe that emphasizes the bike’s naked character. The air dam looking opening sets the 390 apart from its siblings, while the wet finish of the paint with stickering under the lacquer gives a fresh new look.
Suspension and Handling Excellence
The chassis and suspension setup of the 390 Duke reflects KTM’s racing heritage and commitment to handling excellence. Finding that perfect balance when attacking your favorite stretch of tarmac, or sliding around some tight cone-marked corners is easy thanks to the KTM 390 Duke’s 43 mm WP APEX open cartridge fork with adjustable compression and rebound.
The rear suspension features WP APEX Separate piston shock absorber that can also be set for rebound and preload, to find the ideal mix between comfort and traction. This adjustability allows riders to fine-tune the suspension for their weight, riding style, and road conditions.
Braking Performance and Safety
The braking system on the 390 Duke provides confident stopping power with advanced safety features. The motorcycle features a 320mm front disc with radial caliper and a 240mm rear disc, providing excellent stopping power and feel. The system is sensitive to the lean angle of the motorcycle and reduces the chance of locking up a wheel mid-corner under hard braking.
The ABS system includes multiple modes, including dual-channel ABS with SUPERMOTO mode to slide into corners with confidence, applying more brake pressure while cornering as ABS intervenes if front wheel slip is detected.
