After several years away from the saddle, it finally returns—the new KTM Duke 390. Since its last version was introduced in 2017, riders have long awaited a complete overhaul, and in 2025, KTM has delivered something truly exciting. With over 90% of components changed compared to the Gen 2 model, this Gen 3 KTM Duke 390 is not just a refresh—it’s a new era for KTM in the Philippines under a fresh distributor: Lucky Mappy, part of MotorAce Philippines. This relaunch brings a highly updated motorcycle that combines aggressive aesthetics, a re-engineered engine, a premium dashboard, and enhanced features to thrill both new and seasoned riders.
Bold New Engine, Light Chassis, and Improved Ride Dynamics
The heart of the new KTM Duke 390 lies in its all-new LC4c engine, which is a single-cylinder, 4-stroke, liquid-cooled unit with a displacement of 399cc—a slight increase from the previous 373cc. The change comes from a longer stroke: 64mm compared to the earlier 60mm. This updated engine produces 44.3 horsepower at 8,500 RPM and 39Nm of torque at 7,000 RPM, offering more power earlier in the rev range.

Alongside the updated powerplant, KTM also changed the chassis. The new trellis frame now features an aluminum subframe, making it lighter and stiffer. The swingarm and rear suspension have been repositioned to the right side of the bike, providing better weight distribution. The front uses 43mm WP Apex open cartridge forks, while the rear shock is adjustable for rebound and preload—though a tool is required for the latter. Overall, this version feels more agile and balanced, offering a ride that’s both aggressive and forgiving.
Aesthetics That Bite: Sharp, Angular, and Modern
If the performance upgrades don’t grab your attention, the design surely will. The Gen 3 Duke 390 screams aggression from every angle. Its headlight setup, inspired by predator styling, has LED DRLs that wrap around a bulkier unit. Compared to Gen 2, this version has a more muscular stance, made more imposing by its redesigned shrouds, angled radiator cover, and high-set metal fuel tank. It’s available in two bold colors: Atlantic Blue and the signature KTM Orange.
The seat design is also unique. KTM opted for an orange rider seat, which is almost unheard of in the 400cc naked bike category. The passenger seat, in contrast, is black to match the subframe. The overall layout gives the bike a compact yet intimidating presence, and despite the dramatic styling, it remains comfortable for both rider and pillion.
High-Tech TFT Dashboard, Riding Modes, and Advanced Electronics
The 2025 KTM Duke 390 doesn’t just shine in looks and performance—it’s packed with tech that enhances usability and rider control. At the center is a 5-inch full-color TFT display, featuring a clean and animated UI that changes based on the selected riding mode.
| Feature | Functionality Summary |
|---|---|
| Riding Modes | Street, Track, Rain |
| ABS Modes | Road, Supermoto (rear ABS off) |
| Traction Control | On/Off |
| Launch Control | Available after 1,000 km |
| Dashboard | 5-inch full-color TFT |
| Smartphone Connectivity | Yes |
| Shift Light, Lap Timer | Yes |
| Fuel Efficiency | ~22 km/l (tested) |
The three riding modes include:
- Street Mode for daily commuting and full engine power.
- Track Mode to unlock sporty display features like a lap timer and access to Launch Control.
- Rain Mode adjusts engine behavior for better traction in wet conditions.
The ABS system can be toggled between Road and Supermoto mode, where the rear ABS is disabled, allowing for controlled slides—something experienced riders will love. There’s also a traction control toggle, though it only offers On or Off states, with no multiple levels.
KTM has also integrated handy features like a battery voltage reader, engine temperature display, and fuel consumption tracker directly into the dashboard. The display is readable even under bright sunlight, and the menu controls are handled from the left handlebar, making it easy to adjust settings on the fly.
Ergonomics and On-Road Ride Feel: Nimble, Lightweight, and Fun
Sitting on the KTM Duke 390 Gen 3 is a pleasant surprise. With a seat height of 820mm, the bike feels approachable for riders around 6 feet tall. The narrow tank and slim waist allow both feet to touch the ground easily, which boosts confidence in urban traffic. The upright seating position with slightly rear-set footpegs gives a sporty yet relaxed stance. Riders feel connected to the road without sacrificing comfort.
The ride-by-wire throttle is sharp and responsive. Despite being a single-cylinder engine—which typically produces more vibration—the bike feels smoother than expected. Gear shifts are soft thanks to the assist and slipper clutch, though a quickshifter is optional and not included out of the box.
On the road, the Duke 390 handles corners like a dream. Its lightweight frame, combined with Metzeler Sportec M9 RR tires (150/60 rear and 110/70 front), makes for easy flicks through twisties. Braking is confident too, thanks to radially mounted four-piston calipers at the front and a single-piston rear setup, both from ByBre (Brembo’s Indian brand).
The underbelly exhaust, a new addition for Gen 3, improves mass centralization and gives the bike a cleaner look. Although some riders may not love the exhaust note (described as slightly underwhelming), aftermarket options can change that quickly.
Final Verdict: KTM Duke 390 Gen 3 – Is It Worth It?
The 2025 KTM Duke 390 redefines what a 400cc naked bike can offer. It’s light, powerful, rich in features, and wrapped in a design that turns heads. More than that, it finally addresses KTM’s previous weak point in the Philippines—after-sales service. The new distributor, Lucky Mappy, promises to focus on expanding support and parts availability, making the ownership experience much smoother.
This bike feels like it belongs in the next class up, thanks to its high-quality switches, advanced dashboard, and solid build quality. With a price of PHP 300,000, it undercuts some of its Japanese and European rivals while offering features that few bikes in this segment can match.
Whether you’re a beginner looking for your first big bike or a seasoned rider wanting something playful for city and weekend rides, the new KTM Duke 390 is an excellent choice. Just don’t forget to upgrade to that optional quick shifter—it’s worth it.
