Whether you’re weaving through city traffic or attacking twisty mountain roads, the 2025 KTM Duke 390 delivers non-stop thrills without breaking the bank.
In this guide, we’ll dive deep into everything you need to know about the 2025 KTM Duke 390 from its revamped engine and top-tier features to real-world performance, pricing, and why it’s dominating the mid-size bike scene.
2025 KTM Duke 390 Engine
At the heart of the 2025 KTM Duke 390 beats the latest LC4c single-cylinder engine a 399cc liquid-cooled powerhouse that’s Euro 5.2 compliant and refined for smoother, more efficient operation. This isn’t your average mill; it’s a torque monster tuned for instant response and high-rev excitement.
Delivering 44.2 horsepower at 8,500 rpm and 39 Nm of torque at 6,500 rpm, the engine offers a noticeable bump over the previous gen’s 42.9 bhp. Paired with a slick six-speed gearbox featuring a bi-directional quickshifter (optional on some variants), shifts are buttery smooth, whether you’re snapping through gears in the city or holding top-end on the highway.
Performance-wise, expect 0-100 km/h sprints in around 4.3 seconds, making it quicker than most sub-400cc rivals. Top speed clocks in at a GPS-verified 167 km/h (about 104 mph), where it feels planted and eager, thanks to improved aerodynamics and a longer wheelbase for better high-speed stability.
Fuel efficiency? ARAI claims hover around 28-30 kmpl in mixed conditions, but real-world riders report 25-28 kmpl depending on how hard you twist the throttle. With a 15-liter tank, that’s easily 350-400 km between fill-ups perfect for weekend getaways without constant pit stops. The engine’s vibration is minimal post-5,000 rpm, and the updated cylinder head ensures cleaner emissions without sacrificing that signature KTM growl.
Handling and Ride Quality
If power gets you excited, the chassis keeps you hooked. The 2025 KTM Duke 390’s steel trellis frame has been completely redesigned for a 5% weight reduction, tipping the scales at just 168.3 kg kerb. This agility shines in tight corners, where the bike feels like an extension of your body.
Suspension duties fall to a WP Apex 43mm upside-down fork up front (adjustable for preload and rebound) and a WP Apex monoshock rear, both tuned for sporty compliance. Ground clearance is a healthy 183 mm, so potholes and speed bumps won’t spoil your flow. The 17-inch cast alloy wheels wrapped in sticky 110/70 front and 150/60 rear Pirelli Sportcall tires provide laser-like grip, with cornering ABS ensuring you brake late without drama.
Riders praise its flickability: It carves apexes like a GP bike, but stays planted at 140 km/h, notes a recent owner review. The ergonomics have improved too a slimmer tank, thicker seat foam, and 800 mm seat height (or 820 mm optional) make it welcoming for riders from 5’6″ to 6’2″. Pillion comfort is decent for short hops, though this is very much a solo hooligan machine.
Braking is confident with 320 mm front disc and 240 mm rear, squeezed by four-piston radial calipers and a single-piston rear, all modulated by cornering-aware ABS. In Track mode, you can disable rear ABS for slides—pure fun for the spirited.
Tech and Features
KTM doesn’t skimp on gadgets, and the 2025 Duke 390 is a tech feast. The star is the 5-inch bonded glass TFT dashboard crisp, customizable, and Bluetooth-enabled via the KTM My Ride app for turn-by-turn navigation, music streaming, and call handling.
Rider aids include three modes: Rain (gentle throttle, max traction), Street (balanced), and the new Track mode with a race-focused layout, lap timer, and Launch Control.
Yes, Launch Control is standard now hold the clutch, pin the throttle to 7,000 rpm, and release for wheelie-free hole shots. Traction control, supermoto ABS (front-only in Track), and a new cruise control make it highway-friendly for those long hauls.
LED lighting is full-house: projector headlamp, DRLs, and taillight that slice through fog or night rides. The switchgear is backlit with a four-way joystick for glove-friendly menu navigation. Optional heated grips and quickshifter+ round out the premium vibe.
Safety gets a boost with Bosch’s lean-sensitive electronics, ensuring you stay glued during aggressive leans.
Stylish and Aggressive Duke Look
The 2025 KTM Duke 390 looks meaner than ever. Its angular, muscular lines sharp tank extensions, exposed trellis frame, and trellis subframe give it a predator stance. New color options include the sinister Ebony Black (new for 2025), vibrant Electronic Orange, and Atlantic Blue, all with glossy finishes and orange accents for that KTM pop.
The trellis frame’s orange powder-coat peeks through, while the sculpted fuel tank (thinner for better knee grip) and undercut tail section keep it sleek. The textured seat cover adds urban edge, and those Y-shaped alloys scream performance. At 2,147 mm long with a 1,357 mm wheelbase, it’s compact yet imposing park it anywhere, but it’ll draw stares everywhere.
Pricing and Value
Affordability is the Duke’s secret weapon. In India, the 2025 KTM Duke 390 starts at ₹2.95 lakh ex-showroom (after a recent ₹18,000 price cut), making it a steal for the spec sheet. On-road prices hover around ₹3.3-3.5 lakh in major cities, including insurance and registration.
Globally, expect $5,499-$5,899 in the US, and around €5,500 in Europe (down €400 from 2024). Maintenance is reasonable: first service at 1,000 km, then every 7,500 km, costing ₹2,000-3,000 per pop. Resale holds strong, with low-mileage examples fetching 80-90% of original value after a year.
Performance Mileage, Top Speed
On the road, the 2025 Duke 390 shines brightest in its element: spirited street riding. City sprints feel effortless with low-end torque pulling from 2,500 rpm, while highways reward with stable cruising at 100-120 km/h. Top speed of 167 km/h is achievable on open stretches, but wind blast above 140 km/h calls for a screen (aftermarket add-on).
Mileage in aggressive mode dips to 22-25 kmpl, but eco-conscious throttling yields 28-30 kmpl. Owners love its versatility: 150 miles a day at redline, zero issues after 3,000 miles, raves one high-mileage user.
Heat from the single-cylinder is noticeable in traffic (a deflector helps), but manageable with proper gear.
