KTM Duke 390: When the original KTM Duke 390 roared onto Indian roads in 2013, it didn’t just arrive—it exploded onto the scene, redefining what riders could expect from a sub-400cc motorcycle.
That first-generation machine, with its raw power delivery and uncompromising character, created a seismic shift in the Indian performance motorcycle landscape.
Fast forward to 2024, and the third-generation Duke 390 continues that revolutionary legacy while incorporating technological advancements that were once the exclusive domain of much more expensive motorcycles.
KTM Duke 390 Evolution of a Street Fighter
The story of the KTM Duke 390 in India is one of continual evolution. The original 2013 model was a revelation—a lightweight, nimble machine that punched well above its weight class with approximately 43 bhp on tap.
It introduced many Indian riders to true European performance at a relatively accessible price point. That first-generation model was raw, unfiltered, and demanded respect from its rider.
The second-generation Duke 390, introduced in 2017, brought more refinement to the package. It featured a more contemporary design with LED lighting, a larger fuel tank, and ride-by-wire throttle. While it maintained the aggressive character of its predecessor, it offered slightly more everyday usability.
Now, with the third-generation 2024 model, KTM has gone back to the drawing board, creating a motorcycle that’s approximately 90% new. The 2024 Duke 390 represents the most comprehensive update in the model’s history, growing in displacement to 399cc and incorporating technologies previously found only on much more expensive motorcycles.
Styling: Aggressive Evolution
One look at the 2024 Duke 390, and the family lineage is unmistakable. Taking design cues from its larger sibling, the 1290 Super Duke R, the new 390 features a sharper, more angular design that screams aggression.
The headlight assembly has been completely redesigned, now featuring a wider LED unit flanked by boomerang-shaped LED daytime running lights that give the bike a predatory appearance.
The fuel tank extensions are more pronounced, protruding further outward and creating a more muscular stance. These extensions actually reach beyond the inverted fork, adding to the bike’s imposing presence. The tail section has also been revised, maintaining the compact, aggressive look that has become a KTM hallmark.
Available in two striking color schemes—Electronic Orange and Atlantic Blue—the 2024 Duke 390 makes no apologies for its bold appearance.
The orange version, with its matching orange rider seat, is particularly eye-catching, though some riders might prefer the slightly more subdued blue option.
The quality of components has taken a step forward as well. The switchgear feels more tactile and premium, the mirrors offer better stability with reduced vibration, and the overall fit and finish represent a marked improvement over previous generations.
Heart of the Beast: The Engine
Under the skin, the 2024 Duke 390 features a significantly revised powerplant. While still a single-cylinder unit, displacement has increased from 373cc to 399cc, resulting in a modest but noticeable bump in output.
The new engine delivers 46 PS (approximately 45.3 bhp) at 8,500 rpm and 39 Nm of torque at 6,500 rpm—increases of 3 PS and 2 Nm over its predecessor.
What’s more significant than the power increase, however, is how that power is delivered. The new engine features improved thermal efficiency, a more optimized cylinder head, and a refined gearbox.
These changes result in a more accessible power band with better low and mid-range torque, making the bike more usable in everyday riding situations.
The exhaust system has also undergone a complete redesign, returning to an underbelly configuration similar to the first-generation model. This not only contributes to better mass centralization but also produces a throatier, more aggressive exhaust note that perfectly complements the bike’s character.
Perhaps most importantly, despite the increase in displacement and power, the engine maintains excellent fuel efficiency. Under real-world testing, the 2024 Duke 390 delivers approximately 25-28 km/l in city riding and even better figures on the highway—impressive numbers for a performance-oriented machine.
Chassis and Handling: Precision Instrument
The 2024 Duke 390 rides on an entirely new chassis. The steel trellis main frame has been redesigned for increased torsional rigidity, improving feedback to the rider.
The subframe is now made from pressure die-cast aluminum, contributing to the bike’s lightweight nature while maintaining structural integrity.
One of the most significant changes is the adoption of a new curved, open-lattice cast-aluminum swingarm. This banana-style swingarm accommodates the underbelly exhaust and features an offset rear shock mount on the right side rather than the center.
This revised configuration not only makes room for a larger airbox but also helps lower the seat height from the previous 830mm to 820mm (with an option to reduce it further to 800mm).
The suspension has taken a significant step upmarket. The 43mm WP APEX open cartridge fork now features adjustable compression and rebound damping, allowing riders to tailor the front-end feel to their preferences.
At the rear, the WP APEX shock absorber can be adjusted for rebound and preload, further enhancing the bike’s adaptability to different riders and road conditions.
This adjustability is rare in this segment and represents one of the most significant upgrades for the 2024 model. It allows the Duke 390 to be fine-tuned for everything from spirited canyon carving to comfortable commuting or even light touring.
The handling characteristics of the 2024 Duke 390 are nothing short of exemplary. The bike changes direction with telepathic precision, responding to the slightest rider input. Despite this agility, it maintains excellent stability at higher speeds, inspiring confidence even on fast, sweeping corners.
The revised suspension tuning has resulted in a more compliant ride without sacrificing the sharpness that Duke fans have come to expect. Where the previous generations could be harsh over poor surfaces, the 2024 model does a much better job of absorbing road imperfections while still communicating necessary feedback to the rider.
Braking: Confidence-Inspiring Control
Braking performance has always been a strong point for the Duke 390, and the 2024 model continues this tradition. The front brake features a single 320mm disc gripped by a radial-mount four-piston caliper from ByBre (a Brembo subsidiary). At the rear, there’s a 240mm disc with a twin-piston caliper.
What’s new for 2024 is the addition of cornering ABS—a feature typically found on much more expensive motorcycles. This lean-sensitive system modulates braking force based on the bike’s lean angle, providing an extra layer of safety when braking mid-corner.
The system also features a “Supermoto” mode that disables the rear ABS while keeping it active on the front wheel—perfect for more experienced riders who want to slide the rear on tight corners.
The braking setup provides excellent initial bite and progressive power, allowing for precise modulation whether you’re gently slowing for a corner or executing an emergency stop. Combined with the cornering ABS, it inspires tremendous confidence, especially for less experienced riders.
Electronics: Flagship Features in a Middleweight Package
Perhaps the most impressive aspect of the 2024 Duke 390 is its electronics package. KTM has equipped this middleweight naked with technology that would have been unimaginable in this segment just a few years ago.
The centerpiece is a 5-inch bonded glass TFT display that provides exceptional readability in all lighting conditions. This is paired with a redesigned switch cube featuring 4-way menu switches that allow intuitive navigation through the various settings and features.
Riding modes—another first for the Duke 390—include Street (which unleashes the full power with standard traction control intervention), Rain (with softer throttle response and increased traction control), and Track (which unlocks additional features like launch control).
Yes, you read that correctly—the 2024 Duke 390 comes with launch control, a feature typically reserved for high-end superbikes. When engaged in Track mode, this system holds the engine at 7,000 rpm with the throttle wide open, allowing for perfect race starts by simply releasing the clutch.
The bike also features cornering traction control, which uses input from a 6-axis IMU (Inertial Measurement Unit) to modulate power delivery based on lean angle—another premium feature rarely seen in this segment.
Smartphone connectivity is integrated through the KTM MY RIDE system, allowing for music control, call management, and turn-by-turn navigation via the TFT display. While not unique to the Duke 390, these connected features add a layer of practicality to an otherwise performance-focused machine.
For those who want even more performance, the quickshifter+ is available as an accessory, enabling clutchless up and downshifts for even more rapid gear changes.
Ergonomics: Compact but Comfortable
The riding position of the 2024 Duke 390 is sporty yet reasonable for daily use. The handlebar is wide and relatively flat, putting the rider in an assertive but not extreme forward lean. The footpegs are positioned for a slightly sporty stance without being uncomfortably rear-set.
The seat has been redesigned with thicker foam and a narrower profile, improving comfort for most riders. However, taller riders may find the compact dimensions somewhat cramped, especially on longer rides.
The standard seat height of 820mm is accessible for a wide range of riders, and those seeking an even lower stance can opt for the 800mm seat available through KTM’s PowerParts catalog.
Wind protection is minimal, as expected from a naked streetfighter, but the riding position allows the rider to brace against windblast at highway speeds without excessive fatigue.
One minor ergonomic issue that some reviewers have noted is the position of the TFT display, which is mounted relatively high above the handlebar. This positioning can require the rider to look down more than ideal, potentially distracting from the road ahead.
Real-World Performance: The Riding Experience
On the road, the 2024 Duke 390 delivers an experience that is both thrilling and accessible. The engine’s improved torque curve provides punchy acceleration from low revs, making urban riding a joy.
The bike pulls cleanly from as low as 2,000 rpm, though there is some vibration in the 3,000-5,000 rpm range that can be felt through the handlebars and footpegs.
Once past this zone, the engine smooths out considerably and pulls strongly to the redline. The additional 26cc of displacement might not seem like much on paper, but the enhanced mid-range torque is immediately noticeable, particularly when exiting corners or overtaking on highways.
The gearbox is precise and positive, with well-spaced ratios that make excellent use of the engine’s power band. Clutch action is light thanks to the Power Assist Slipper Clutch (PASC), which also prevents rear-wheel hop during aggressive downshifts.
In urban environments, the Duke 390 is a weapon. Its narrow profile, light weight (a claimed 168.3 kg with a full tank), and sharp steering make it ideal for slicing through traffic.
The improved low-end torque reduces the need for frequent gear changes, while the responsive throttle allows for instant acceleration when gaps appear.
On twisty roads, the Duke 390 truly comes alive. The precise steering, adjustable suspension, and strong brakes allow the rider to carve through corners with surgical precision. The bike feels planted and stable, inspiring confidence to push harder with each turn.
Highway cruising is more comfortable than previous generations thanks to the revised ergonomics and larger 15-liter fuel tank, which provides a theoretical range of approximately 375-420 kilometers. While vibrations are present at certain rpm ranges, they’re not severe enough to cause discomfort on moderate-length journeys.
Value Proposition: Premium Features at a Competitive Price
Priced at Rs. 2.97 lakh (ex-showroom), the 2024 Duke 390 represents excellent value despite a slight price increase over its predecessor. When you consider the adjustable suspension, cornering ABS and traction control, launch control, ride modes, and TFT display, the bike offers technology that would cost significantly more on larger displacement machines.
Running costs remain reasonable despite the bike’s performance orientation. Fuel efficiency is commendable, and KTM has increased the service intervals for the 2024 model, reducing long-term maintenance expenses.
However, potential owners should be aware that parts and labor at authorized KTM service centers typically cost more than those for Japanese or Indian brands.
Resale value has traditionally been strong for the Duke 390, reflecting both its desirability and durability. The 2024 model, with its significant upgrades, is likely to continue this trend.
Competition: Standing Out in a Crowded Segment
The 2024 Duke 390 faces stiffer competition than ever before. Rivals include the Honda CB300R, BMW G 310 R, Triumph Speed 400, Royal Enfield Guerrilla 450, and even KTM’s own 390 Adventure for those seeking more touring capability.
What sets the Duke 390 apart is its uncompromising focus on performance and its comprehensive electronics package. While some competitors may offer better refinement or lower prices, none deliver the same combination of raw performance and sophisticated technology in this segment.
The Triumph Speed 400 and Royal Enfield Guerrilla 450 offer more retro-styled alternatives with strong torque delivery but lack the Duke’s cutting-edge electronics.
The BMW G 310 R brings German engineering and brand prestige but falls short in outright performance and features. The Honda CB300R offers Japanese reliability and refinement but with less power and fewer features.
