KTM 390 Adventure X

Overview

Performance And Engine

The KTM 390 Adventure X uses a 398.63 cc single-cylinder, liquid-cooled engine from KTM’s LC4c family, which is also found in the 390 Duke and 390 Adventure. It makes 46 PS at 8,500 rpm and 39 Nm of torque at 6,500 rpm, which is better than the older 390 Adventure and matches other current 390-class bikes. The engine is tuned for strong low and mid-range power, making it easy to ride in both city and highway settings. Its liquid cooling and 12.71:1 compression ratio help it run smoothly and manage heat, even in hot Indian weather. The 4-valve head and Bosch-style fuel injection provide quick throttle response and meet emission standards.

On the road, the 390 Adventure X feels as strong as a 400 cc twin when overtaking or picking up speed. Its single-cylinder engine delivers power smoothly and steadily, not with a sudden rush at high revs. This makes it good for touring, quick lane changes, and relaxed rides in the hills. It is easy for less experienced riders, but it still has enough power for two people and luggage on the highway. The bike has a 6-speed manual gearbox with a ‘1 down, 5 up’ pattern, which is common for KTM and other performance bikes in India. Gear shifts are light and precise. Third and fourth gears work well for city and highway use, while fifth and sixth gears make highway cruising at 100–120 km/h comfortable.

The 390 Adventure X includes an Assist & Slipper Clutch and a Quickshifter+ system, which lets you shift up without using the clutch and downshift more smoothly. This feature is rare at this price in India. The slipper clutch helps prevent rear wheel skipping during hard braking, making the bike more stable on rough roads and steep slopes. The assist clutch makes the lever lighter, so it is less tiring in traffic or on long rides. The transmission is designed for comfort on highways and touring, with taller gears that keep the engine relaxed at cruising speeds but still give enough power in lower gears for city riding and quick overtakes.

Several Indian motorcycle websites and spec sheets report that the KTM 390 Adventure X has a top speed of 155-160 km/h. Some sources list 155 km/h, while others estimate 160 km/h. With its 46 PS engine, light weight of about 181–182 kg, and tall gearing, the bike handles highways well and can cruise at 110–120 km/h with manageable wind and engine noise.

Mileage And Fuel Efficiency

KTM India and major spec sites say the ARAI-claimed mileage for the 390 Adventure X is 30 kmpl, based on lab tests with the 398.63 cc BS6 engine. This figure comes from steady-speed testing and shows the best possible fuel efficiency, not what you will always get in real-world riding. The 30 kmpl rating puts the 390 Adventure X ahead of many bigger ADVs and some 400 cc rivals for mileage, thanks to its light weight, 14.5-litre tank, and efficient fuel injection. On highway test runs, the engine is tuned to run at 40–50 km/h and 4,000–6,000 rpm, which helps save fuel while still giving enough power.

In real-world Indian conditions, owners typically get 28-33 kmpl on the KTM 390 Adventure X, which is slightly lower than the official ARAI number. In the city, mileage is often around 24–28 kmpl, especially in traffic or during stop-and-go riding. On the highway, riders say the bike can achieve 30–33 kmpl at a gentle throttle and steady speeds of 80–100 km/h, giving a range of about 400–430 km per tank. Most touring riders see 28–30 kmpl on mixed routes, with careful riding approaching 33 kmpl and more aggressive riding dropping to 24–26 kmpl.

Features And Technology

The KTM 390 Adventure X is one of the most feature-packed and high-tech 390 cc adventure bikes in India. It brings together KTM’s performance background with modern electronics made for Indian touring and mixed road conditions.

1. 5 inch full colour TFT instrument cluster: The KTM 390 Adventure X adopts a 5 inch full colour TFT display that sits at the centre of the cockpit, showing speed, RPM, gear position, fuel level, real time and average mileage, trip data, service due indicator, and navigation prompts in a crisp, race inspired layout, giving the bike a premium, high tech feel on Indian roads.
2. Bluetooth based navigation and smartphone connectivity: The TFT is integrated with Bluetooth, allowing smartphone linked navigation, call and SMS alerts, and access to some India centric portals that offer turn by turn routing overlays, making the 390 Adventure X one of the most connected adventure tourers in the 400 cc bracket for Indian riders who rely on phone based maps and communication.
3. Two riding modes with Off road ABS: The 390 Adventure X offers Street mode and Off road ABS mode, with Street optimised for highway and tarmac use in India, while the Off road ABS mode deactivates rear wheel ABS to let the rear tyre slip on loose or patchy surfaces, improving control on gravel and mud covered rural connect roads.
4. Cornering ABS and traction control as standard: The bike is equipped with Cornering ABS and traction control, which adapt braking and power delivery based on lean angle, helping to maintain stability on Indian highway curves, wet tarmac, and sudden braking scenarios without over simplifying the riding experience.
5. Cruise control and ride by wire throttle: The 390 Adventure X features a cruise control system tied to a ride by wire throttle, allowing riders to maintain a steady speed on Indian highways without constant throttle twist, reducing fatigue on long distance inter city or state level runs.
6. Quickshifter+ and Assist & Slipper Clutch: The 390 Adventure X comes with Quickshifter+ for clutch less upshifts and smoother downshifts, combined with KTM’s Assist & Slipper Clutch, which lightens lever effort in city traffic and reduces rear wheel chatter under hard engine braking, a notable upgrade over the older 390 Adventure in the Indian line up.
7. Full LED lighting suite with DRLs: The headlamp, tail lamp, and turn indicators are all LED based, with integrated DRL style pilot lamps that enhance daytime visibility and night riding clarity, giving the 390 Adventure X a sharp, modern face suitable for everything from packed city streets to open highway and hills touring.
8. Single channel, switchable ABS with 320 mm front disc: The Indian spec 390 Adventure X runs a single channel ABS system with a 320 mm front disc and 240 mm rear disc, with ABS that can be toggled into Off road mode, allowing rear wheel slip on loose surfaces while still retaining front wheel safety, a setup tuned for mixed surface Indian adventure touring.
9. USB Type C charging port: The bike includes a USB Type C charging port near the instrument/console area, enabling faster charging for modern smartphones, GPS devices, and action cameras, particularly useful for navigation heavy touring and long distance highway linked rides in India.
10. Adjustable or touring focused windscreen: The 390 Adventure X carries a fixed or modestly adjustable touring style windscreen that helps manage wind blast at 100–120 km/h, improving rider comfort on long highway runs while still retaining the ADV style upright stance and visibility required for Indian style adventure riding.
11. Service due indicator, shift light, and trip oriented prompts: The onboard electronics include a service due indicator, a shift light on the TFT, and prompts for odometer, trip distance, fuel range, and time, keeping riders informed about maintenance cycles, gear position, and fuel status during city highway touring combinations.
12. Remote saddle unlock and hazard light integration: The bike features remote saddle unlock for easy access to the pillion seat and under-seat compartment, along with hazard light functionality, which is practical for breakdowns, slow moving traffic, and night rides on poorly lit Indian roads and rural stretches.
13. Pass switch and engine kill switch:Additional rider aid hardware includes a pass switch to signal presence to other vehicles and a thumb mounted engine kill switch on the handlebar, improving safety and convenience in mixed traffic Indian conditions and during quick stop start highway manoeuvres.
14. 19”/17” cast alloy wheel tubeless setup: The 390 Adventure X rolls on 19 inch front and 17 inch rear cast alloy tubeless wheels, which favour tarmac oriented durability and low maintenance, making it a road biased, touring ready ADV suited to highway heavy Indian journeys while still retaining enough ground clearance and ADV character for occasional mixed surface excursions.
15. Rider centric connectivity and future ready ECU architecture: The 390 Adventure X is built on a modern ECU architecture designed to support software based updates and potential future rider assist features, making it “ready” for upcoming KTM branded tech campaigns and firmware based enhancements in the Indian market, even if those features are not yet fully activated on the current model.

Build Quality

The KTM 390 Adventure X carries on KTM’s tradition of strong, motorsport-inspired engineering. Its chassis and bodywork feel solid and premium for a 400 cc adventure bike in India. The split-trellis frame, 19/17-inch cast-alloy tubeless wheels, and 181 kg weight make the bike feel stable and substantial without being hard to handle. Overall, it feels like a globally engineered, India-built ADV instead of a basic, India-only model.

Fit and finish is generally neat, with well aligned fairings around the headlamp, tank side panels, and tail section, and the plastics feel firm and well locked, capable of handling repeated highway assaults and minor gravel bump contact on Indian style mixed surface roads. The 5 inch TFT, LED headlamp and tail lamp, and rubber coated switchgear are all tightly mounted, with wiring tucked away and protection plates visible on key metal components, which owners and Indian users note hold up well over time if routine maintenance is followed.

At the hardware level, the 390 Adventure X uses a 398.63 cc LC4c single with associated fuel injection, radiator, and exhaust plumbing that are all visible and contribute to the bike’s premium looking under fairing area, while the 320 mm front disc, single channel ABS, and 190 mm rear travel are sourced from KTM’s global ADV parts bin, giving it a “over spec for segment” feel compared with rivals at similar price points. For an Indian market 390 class ADV, the 390 Adventure X’s build quality is widely regarded as strong and reassuring, with most long term owners reporting minimal rattle or panel looseness even after extensive touring.

Handling

Handling is one of the best parts of the KTM 390 Adventure X. Indian users often praise its agility for a 390 cc adventure bike, especially on winding highways, hill roads, and uneven stretches between cities. With a 181 kg weight, 825 mm seat height, 150 mm ground clearance, and 19/17-inch wheels, the bike feels tall but nimble, more like a lightweight ADV than a heavy off-roader.

The upright off road style steering, wide handlebars, and long front suspension travel (around 190 mm) make the 390 Adventure X very confidence inspiring over potholed highways, broken tarmac, and gravel patches, where the forks soak up big compressions while still feeding back enough information to the rider. Cornering ABS and traction control further enhance stability when the bike is leaned into highway or hills bends, allowing experienced riders to push the envelope safely while still keeping it accessible for newer ADV buyers tackling Indian style mixed surface routes.

On smooth state highway type tarmac, the 390 Adventure X behaves like a refined, fast touring machine, with cruise control and 6 speed gearing letting it hold 100–120 km/h comfortably while the 19 inch front wheel and ADV geometry provide a stable, planted feel without excessive wobble. The 19”/17” cast wheel package, though biased towards tarmac durability, still allows the bike to tackle loose surface car tracks and semi dirt connecting roads at moderate speeds, making it a versatile “tarmac with occasional dirt” companion for Indian style adventure touring.

Comfort

Comfort is a big plus for the 390 Adventure X among 390-class ADVs in India. The cockpit is tall but comfortable, made for both sitting and standing on long rides. The 825 mm seat height, 170 mm-wide seat, and gentle shaping provide good thigh support and a stable seat for most riders. The narrow tank and flat sides also help make the bike easy to use for many Indian riders.

The upright handlebar, 5 inch TFT within clear line of sight, and moderate knee bend posture make the riding position ideal for extended highway cruises, with the rider’s torso slightly leaned back from the windscreen, reducing fatigue on 200–300 km plus stretches across Indian states. Users from India centric channels note that the 390 Adventure X feels far more comfortable than older gen 390 Adventure style layouts, with the seat ergo, handlebar arc, and footpeg placement tuned to minimise wrist and lower back strain even at 100 km/h for 2–3 hours at a stretch.

For pillion comfort, the 390 Adventure X offers a broader, well padded rear seat with a slight upsweep and grab rail integration, which is more comfortable than many 390 class platforms and works well for pillion assisted touring on Indian highways. The 14.5 litre tank and long range capability (around 400+ km per tank in mixed use) further enhance touring comfort, reducing the need to constantly stop for fuel while still allowing the ADV to stay narrow enough between the rider’s knees for easy mounting and low speed handling in Indian traffic.

Styling

The KTM 390 Adventure X features KTM’s sharp ‘Adventure by KTM’ design, with a 390 cc ADV shape that mixes off-road style with highway touring presence. It has a tall, narrow tank, long-travel front fork, 190 mm front fender, and 150 mm ground clearance, giving it an aggressive, dirt-ready look that still fits well on Indian highways and city streets.

From the front, the 390 Adventure X is dominated by a large, blade like headlamp area with a wide LED headlamp, integrated DRL style pilot lamps, and a broad chin fairing that houses the 320 mm front disc and long stroke fork, giving the bike a sturdy, off road inspired face. The side profile showcases the 398.63 cc single cylinder engine, a 14.5 litre fuel tank cover, and a tall, upright seat that flows into a compact rear cowl, echoing KTM’s global ADV family proportions and visually resembling a “small 690 style” ADV for the Indian market.

The rear section adopts a compact, tail shrunk layout with a small licence plate carrier, short mounted exhaust, and a modest rear fairing that keeps the bike visually light despite its 181 kg kerb weight, helping it feel more agile than bulkier HD or BMW class ADVs in Indian traffic stop and go. The 19”/17” cast alloy tubeless wheel setup, knobby style dual purpose tyres, and handguard style panels (on some accessory laden stock images) complete the earth and asphalt ready look, while still keeping the 390 Adventure X street legal and practical for routine city highway hills combinations in India.

Color Options And Variants

In India, the KTM 390 Adventure X is offered in a simple two colour lineup that keeps the ADV touring oriented buyer’s choice focused and style centric. Colour options are

1. Ceramic White
2. Electronic Orange

All colour options share the same 390 Adventure X specific graphics layout—with KTM Adventure branding, model logo decals, and ADV themed striping—so the visual difference is purely in base paint and graphic flavour, not in shape or bodywork.

The KTM 390 Adventure X is positioned as a distinct, mid range offering within the broader 390 Adventure family range in India, with a simplified variant structure that avoids over segmentation. Indian spec portals and KTM India aligned outlets describe the 390 Adventure X as a single variant, 1 model configuration (often tagged simply as “390 Adventure X”), which is sold under the 390 Adventure-X name while sharing the same 398.63 cc full fat engine and core hardware as the higher spec 390 Adventure models.

What separates the 390 Adventure X from the full fat KTM 390 Adventure and higher end 390 Adventure S/R trim levels in India is mainly the colour palette and some feature trim level differences, rather than a change in underlying chassis, suspension, or engine. For example, the 390 Adventure X gets the same 46 PS, 39 Nm LC4c single, 150 mm ground clearance, and 190 mm front suspension travel but may sit as a “value oriented” or “touring focused” step down line in the 390 Adventure range marketing ladder, with pricing positioned below the top end 390 Adventure S and R variants.

Value For Money And Pricing

The KTM 390 Adventure X sits at the lower end of the 390 class adventure touring spectrum in India, with an ex showroom price running at about ₹ 3,43,250 in Delhi and similar tier 1 cities. At the on road level, the 390 Adventure X climbs to roughly ₹3.96 lakh in Delhi, with other major cities such as Mumbai, Pune, Hyderabad, and Chennai typically landing in the ₹4.00–₹4.15 lakh on road band, depending on state wise RTO and insurance calculations. Within KTM’s own 390 Adventure family, the 390 Adventure X is clearly positioned below the full fat KTM 390 Adventure, for the base-engine version but higher spec 390 Adventure-S entries, making the 390 Adventure X a sort of “premium touring X” variant two steps up from the base 390 Adventure but still below the outright top end 390 Adventure-R-style models.

From a value for money standpoint, the KTM 390 Adventure X is widely regarded as one of the strongest value 390 class ADVs in the Indian market, given its core hardware and feature set. For its sub ₹3.45 lakh ex showroom ticket, the 390 Adventure X delivers a 398.63 cc LC4c single, 46 PS, 39 Nm, a 5 inch full colour TFT with Bluetooth based navigation, cruise control, cornering ABS, traction control, and a 19”/17” cast wheel tubeless setup, all of which are class leading extras for any 400 cc bracket bike in India.

Several users call the 390 Adventure X “one of the best value for money ADV bikes in India,” noting that it offers almost everything you’d want from the 390 Adventure platform—strong highway performance, decent off-road-ready ground clearance, and a connected tech cockpit—at a price that is nearly ₹70–80 thousand cheaper than the fully loaded 390 Adventure in comparable trims. The touring focused 19”/17” cast wheels, 14.5 litre tank, and 28–30 kmpl real mileage figures further enhance value by making it practical for long distance Indian style adventure touring without the maintenance and setup quirks of a fully-spoked-wheel off-roader.

Where the 390 Adventure X may feel slightly premium compared with budget oriented 250–350 cc rivals is in the upfront ex showroom and insurance costs, but users counter that the 390 class performance, 46 PS punch, and modern electronics pay back over time in terms of highway touring enjoyment and resale market appeal. Overall, the 390 Adventure X’s value proposition is best seen as a “touring focused KTM 390 Adventure-lite”: you pay a sensible premium over the base 390 Adventure, but gain a connected tech, highway ready, semi off road capable 390 that justifies the extra cost through hardware, features, and long range touring capability.

The KTM 390 Adventure X operates in the 350–450 cc adventure touring and lightweight ADV segment, where it faces a mix of larger displacement rivals and more budget focused options.

1. Royal Enfield Himalayan 450
2. BMW G 310 GS
3. Triumph Scrambler 400X
4. Triumph 400 X

Across Indian comparison platforms, the 390 Adventure X is often recommended as the “best value, tech rich 390 class ADV”, while the Himalayan 450, BMW G 310 GS, and Triumph 400X are seen as more lifestyle or budget oriented alternatives that trade some hardware and electronics for a lower price or different brand appeal.
