Overview
Performance And Engine
The bike has a liquid-cooled, 349.32 cc single-cylinder engine with DOHC and four valves. It produces 41.5 PS at 8,600 rpm and 33.5 Nm of torque at 7,000 rpm. The Bosch electronic fuel injection system delivers precise fuel and provides quick throttle response, making the bike lively and quick to accelerate. The radiator keeps the engine cool, even in hot Indian weather. A modern balancer shaft reduces vibrations, keeping power smooth at high revs and keeping the engine reliable.
The smooth 6-speed gearbox helps the bike shift easily from low-speed agility to high-speed stability. The slipper clutch stops the rear wheel from hopping during hard downshifts. The gears shift cleanly, so riders can move through traffic or overtake on the highway with little effort.
The KTM 390 Duke can hit a top speed of about 167 kmph. Its light trellis frame and aerodynamic design help keep it stable at high speeds. The bike accelerates quickly, making it a strong choice among performance-naked bikes on Indian roads. The chassis is tuned to stay steady even in crosswinds or on rough surfaces. Large disc brakes and dual-channel ABS give you strong stopping power to match its speed.
Mileage And Fuel Efficiency
The ARAI rates the KTM 390 Duke’s mileage at about 28.9 kmpl. This number comes from standard tests done in controlled conditions, so real-world mileage can be different depending on how and where you ride in India. The rating shows that the 349.32 cc engine is efficient when ridden carefully, and it highlights the work KTM put into making the engine both powerful and fuel-efficient.
In everyday use, Indian riders usually get about 30 kmpl from the 390 Duke. The mileage depends on how you ride—steady speeds and gentle throttle help you get better fuel economy, while aggressive riding and lots of gear changes in traffic use more fuel. Many owners like that, even with over 40 PS of power, the bike is still efficient for daily rides and weekend trips. Experienced riders often get even better mileage by using higher gears and keeping a steady speed, making the 390 Duke a surprisingly efficient touring bike.
Features And Technology
The KTM 390 Duke is a premium, performance-focused naked bike for India. It has a high-tech chassis, a powerful single-cylinder engine, and advanced electronics that set it apart from other 350-class bikes. Here are its main features:
- Advanced Instrument Clusters: :The KTM 390 Duke comes with a 5 inch bonded glass TFT display on the top spec Indian variant, offering multiple display themes, Bluetooth based smartphone connectivity, incoming call and SMS alerts, music playback control, and real time turn by turn navigation guidance tailored for Indian navigation apps and routes.
- Performance Oriented Engine: It is powered by a 349.32 cc, single cylinder, liquid cooled, 4 stroke, DOHC LC4c engine, tuned under BS6.2 norms to deliver around 41.5 PS of power at 8,600 rpm and 33.5 Nm of torque at 7,000 rpm, giving strong mid range punch that suits Indian city highway acceleration and overtaking.
- Sophisticated Transmission System: The motorcycle uses a 6 speed manual gearbox paired with a power assisted slipper clutch and KTM’s Quickshifter+ system, enabling clutchless upshifts and downshifts, softer gear lever effort, and reduced rear wheel chatter during aggressive downshifts on Indian style braking points.
- Comprehensive Braking Safety: The bike is equipped with petal style disc brakes, featuring a 320 mm front disc with a new four piston radial calliper and a 240 mm rear disc with a twin piston calliper, supported by dual channel Cornering ABS and Supermoto ABS that enhance stability and control during spirited riding and in wet conditions.
- Ergonomic and Practical Design: The India spec model offers a seat height of around 800 mm in the standard configuration, with an optional 820 mm higher seat available via the spare parts catalogue, combined with a revised chassis that improves lean feedback and high speed stability for Indian style twisty roads and highway sections.
- Modern Lighting and Indicators: The KTM 390 Duke features an all LED lighting setup, including a segmented LED headlamp with integrated DRLs, LED turn signals, and a compact LED tail lamp, providing better visibility in Indian traffic, on foggy overhead bridge sections, and on late evening city rides.
- Advanced Electronics and Controls: The TFT fitted variants feature a new 4 way menu controller on the left handlebar switchgear, allowing riders to switch between Street and Rain ride modes, toggle rider aids, adjust cruise control, and change display themes, navigation layouts, and instrument setups without taking their hands off the handlebars.
- Robust Build and Tyres: The India spec 390 Duke rides on lighter, spoked style wheels with a high grip radial tyre setup, typically 110/70 17 at the front and 150/60 17 at the rear, tuned for sharp turn in response, improved ride comfort over patchy tarmac, and confident cornering on Indian style B roads and highways.
Build Quality
The KTM 390 Duke is built at the Bajaj-KTM plant in India and designed to meet KTM’s global quality and durability standards. Its steel trellis frame and aluminium subframe keep the bike strong and stable, even at high speeds or in sharp turns. The panels fit well, and the paint and plastic finishes are smooth and durable, holding up better than many other bikes in this price range.
High-quality parts and careful assembly keep key components like the forks, swingarm, and suspension linkages secure, even on rough roads. The 43 mm WP APEX forks, ByBre brake calipers, and spoked wheels all feel sturdy and well-made, showing the bike’s premium quality for its price. Overall, the 390 Duke looks and feels like a bigger, more expensive bike thanks to its solid build and clean finish.
Handling
The KTM 390 Duke is very precise and agile, making it one of the easiest middleweight bikes to handle on Indian roads. Its short wheelbase and slightly longer Gen-3 frame balance quick steering with stability at speed, so you can move through city traffic and change lanes confidently. The wide handlebars and 183 mm ground clearance help you handle tight turns and lane-filtering with ease.
When cornering, the chassis gives you clear feedback through the handlebars and footpegs, making it easy to stay on your line, even on twisty or hilly roads. The WP APEX suspension is set up for both quick handling and stability. The front forks stay firm during hard braking, and the rear shock keeps the back wheel steady over bumps. Cornering ABS and adjustable suspension help the bike stay stable and predictable, even on rough or mixed roads in India.
Comfort
KTM has made the 390 Duke sporty but still comfortable enough for daily riding. The 800 mm seat height and relaxed riding position suit most Indian riders. The handlebars are set to reduce wrist strain, and the footpegs give a natural, slightly forward-leaning posture. The seat is now thicker and better shaped, with enough padding for fun rides and short highway trips without feeling too soft.
The suspension is tuned to handle speed bumps, potholes, and rough patches while keeping the bike’s handling sharp. This makes the Duke less tiring to ride on mixed roads than a pure track bike, though long rides at high speeds can get a bit uncomfortable for your seat and back. For riders who want both performance and comfort, the KTM 390 Duke offers a good balance in the Indian middleweight class.
Styling
The KTM 390 Duke in India keeps the aggressive, bare-naked streetfighter style of the global model, with some tweaks for local tastes. Its new two-piece steel trellis frame and aluminium subframe make the bike look wider and more solid at the back, giving it a compact but strong stance for city and highway riding. The orange trellis frame and underbelly exhaust are easy to spot, giving it a sporty, technical look that stands out from regular commuter bikes.
The front of the bike features a sharp, blade-like nose with a sculpted headlamp and a narrow central DRL, giving the Duke a bold, almost ‘faceless’ look like bigger KTM models. The all-LED lights, including the headlamp, DRLs, and tail lamp, make it feel premium, and the sharp graphics look modern even in daylight. The tank and side panels have tightly fitted bodywork and a deep air-dam opening, giving the 390 Duke a more aggressive look than the previous generation.
For the Indian market, KTM includes an engine guard and saree guard, which make the bike look a bit bulkier than the international version. However, these parts are painted black or dark grey to blend in and keep the bike looking sporty. The rear has a slightly larger number-plate holder and tail section to meet Indian rules, but the sharp, naked-bike style is still clear.
Colour Options And Variants
In India, the KTM 390 Duke comes in three colour options, each highlighting its sporty style and giving a different feel. The official KTM India website and major bike portals list these three: Gun Metal Grey, Atlantic Blue, and Electronic Orange.
- Gun Metal Grey
- Atlantic Blue
- Black
Indian riders often mention that all three colours use high-quality lacquer paint with stickers under the clear coat. This keeps the graphics looking sharp and prevents them from peeling, even in strong sun and dust.
In India, the KTM 390 Duke is sold as a single-variant streetfighter. It sits below the more track-focused Duke R and above the 350 cc-based 390 Duke ‘350cc’ variant, which was introduced to fit under a lower GST tax bracket.
- KTM 390 Duke
- KTM 390 Duke R
Indian buyers can pick the standard 390 Duke (Gen-3, 349.32 cc) for daily street use with full features and sporty looks. The 390 Duke R is aimed at those who want a more race-inspired style and a slightly more aggressive setup, but still within the 390 cc family.
Value For Money And Pricing
The KTM 390 Duke is positioned in India as a “premium budget” middleweight streetfighter, with pricing that reflects KTM’s aggressive positioning under the new 349 cc displacement bracket. The KTM 390 Duke starts at ₹ 2,77,268 (ex showroom, Delhi) for the single variant Gen 3 model. Compared with the previous 399 cc based Duke, this revised ex showroom price makes the 390 Duke more tax friendly while still offering full spec tech, effectively closing the gap with 300–310 cc rivals. Within the wider KTM Duke family in India, the 390 Duke sits above the 250 and 200 Duke and directly below the more track focused 390 Duke R, which is marketed as a higher spec, more aggressive sibling despite using the larger engine platform.
The KTM 390 Duke offers great value in India, giving you lots of features for the price in the sub-350 cc class. For under ₹2.8 lakh (ex-showroom), it comes with full LED lighting, a 5-inch TFT display, multiple riding modes, cruise control, ride-by-wire, MTC, cornering ABS, supermoto ABS, and quickshifter+—features usually found on more expensive bikes. The 349.32 cc engine delivers strong performance on both city and highway rides, allowing KTM to keep the price low while still competing with 300–310 cc rivals.
KTM Bajaj’s local assembly and wide service network in India give the 390 Duke an advantage in warranty and long-term ownership costs compared to imported bikes like the BMW G 310 RR or Aprilia Tuono 457. Thanks to its strong fan base and performance image, the 390 Duke usually keeps its resale value well, which many Indian users see as a big plus. Overall, the KTM 390 Duke is often called a ‘gateway to big-bike performance’ at a lower price, especially in the 250–350 cc segment, where rivals may offer fewer features or cost more.
