Press ratings
Versatile, easy, low-seated and frugal; soft braking, lack of low-end torque, basic display and limited wind protection for taller riders.
An ideal urban bike, light and lively, with a low seat; reduced electronics, non-adjustable suspension and levers, vibrations at the top of the rev range.
Covers the R version: genuine off-road ability, strong and engaging engine, good technology; tall seat, vibrations, paid-for options.
Covers the R version: best power-to-weight ratio in its class, outstanding suspension and electronics (IMU); the heaviest in its segment, awkward side stand.
Covers the R version: convincing chassis, fork and off-road electronics; engine too peaky off-road (stalling), problematic side stand.
Press synthesis
What the world’s press says
Three reviews cover the 390 Adventure X. MCN rates it 3/5, while 1000PS and Ultimate Motorcycling tested it without a numeric score. Reviews of the R version, from the same generation but better equipped, are more enthusiastic: MCN gives it 4/5 and Motorcycle.com 92.5/100, while RevZilla finds it imperfect but a big step forward. No French press review of this generation was found.
What reviewers like: a strong, smooth single (MCN), an easy, agile and frugal bike with a low seat (1000PS), an excellent urban bike, light and lively (Ultimate Motorcycling), and a reasonable price.
What they criticise: a weak, spongy front brake (MCN, 1000PS), a basic, hard-to-read LCD dash (MCN, 1000PS), limited electronics and visible cost-cutting (MCN, Ultimate Motorcycling), non-adjustable suspension and levers (Ultimate Motorcycling), a lack of low-end torque and limited wind protection for taller riders (1000PS). For MCN, it should deliver more for the money.
Key quotes
"It’s pleasant to ride but could – and should – deliver more. Or have a price starting with a four to make it seem a bargain…"
"KTM’s LC4c motor is the star of the show."
"The KTM 390 Adventure X impresses as a versatile all-rounder with a clear street focus. It excels in daily use, touring, and light off-road excursions, but demands active riding. Less spectacular than the R, yet a more sensible choice for many riders."
"The KTM 390 Adventure X may be the ultimate urban adventure bike."
"Its combination of high performance, curb appeal, and relatively low price would seem to push this bike past the “entry-level” barrier, and into the realm of something almost any adventure rider should consider."
Pros
- Strong, smooth LC4c single, 45 hp A2-compliant
- Light (176 kg with a full tank) and agile
- Low 825 mm seat
- Frugal: about 3.5 L/100 km, nearly 400 km of range
- Standard Bluetooth and USB-C socket
- Premium Manufacturer’s Warranty of up to 4 years
Cons
- Weak, spongy front brake
- Basic, hard-to-read LCD dash
- Limited electronics (no traction control according to the manuals, no immobiliser)
- Non-adjustable suspension and levers
- Lack of low-end torque, vibrations at the top of the rev range
- Limited wind protection for taller riders
Our review
X or R: which 390 Adventure?
Since 2025, the 390 Adventure has come in two versions. The 390 Adventure X is the entry-level, road-biased version: 19- and 17-inch cast wheels, non-adjustable 200 mm suspension, an 825 mm seat and an LCD dash. The 390 Adventure R targets off-road riding with 21- and 18-inch spoked wheels, adjustable 230 mm suspension, an 870 mm seat and a TFT screen. The 2026 model year carries over the 2025 specifications unchanged. Both bikes are built in India.
How much does it cost?
KTM France lists the 390 Adventure X at €6,199 (recommended retail price), in orange or white. In October 2026, the website offers it on promotion at €5,599, without stating how long the offer lasts. The 390 Adventure R costs €7,199. In the United States, the X sells for $6,499 and the R for $7,699. The quickshifter (Quickshifter+) is optional, and cruise control is available as a KTM PowerParts accessory.
How good is the engine?
The 398.7 cc LC4c single (89 x 64 mm), introduced on the 390 Duke, makes 45 hp (33 kW) at 8,500 rpm and 39 Nm at 7,000 rpm, making it directly A2-compliant. It has an assist and slipper clutch, a 6-speed gearbox and a stainless exhaust with no end silencer. For MCN, this engine “is the star of the show”; 1000PS, however, finds it short of low-end torque, and Ultimate Motorcycling notes vibrations at the top of the rev range. An engine software update, applied through a recall, has reduced low-rpm stalling.
How does it ride?
The steel trellis frame has a bolt-on subframe and a cast aluminium swingarm. The 43 mm WP APEX upside-down fork is non-adjustable, and the shock only offers tool-adjustable preload. KTM France quotes 200 mm of rear travel, while the owner’s manual gives 205 mm; likewise, the steering head angle is 62.5° from horizontal (27.5° from vertical) on the website, against 62.9° in the manual. Braking relies on a 320 mm front disc and an axial two-piston Bybre caliper (the manual mentions four pistons, probably a typo). MCN and 1000PS find this front brake weak and spongy. At 176 kg with a full tank and with 232 mm of ground clearance, the X remains light and agile according to every review.
What electronics?
Standard equipment includes two-channel ABS with an Offroad mode that frees the rear wheel, a 5-inch LCD dash, Bluetooth connectivity, a USB-C socket and full LED lighting. Sources contradict each other on the rest. KTM’s 2025 press kit credits the X with riding modes and traction control (non-cornering), but the 2025 and 2026 European owner’s manuals and the US manual for the X make no mention of them, and MCN confirms there is no traction control and only one power mode. The manual mentions cornering ABS regulation in Road mode, which MCN and Ultimate Motorcycling dispute as the bike has no IMU. MCN also notes the lack of an immobiliser and non-adjustable levers.
Fuel consumption and maintenance
KTM quotes 3.4 L/100 km; 1000PS recorded about 3.5 L/100 km in everyday use, giving a range of nearly 400 km from the 14-litre tank. The manual calls for an oil change every 10,000 km or every year and a valve clearance check every 20,000 km. KTM’s Premium Manufacturer’s Warranty covers the bike for up to 4 years if it is serviced within the dealer network.
Recalls
Two campaigns affect 2025-2026 390 Adventure X models: an engine software update against low-rpm stalling, and replacement of the spring on forged side stands, which can break under vibration.
Who is it for?
The 390 Adventure X suits A2 licence holders and shorter riders looking for a light, frugal and manageable adventure bike for the road, the city and easy trails. Those aiming for serious off-road riding or a full electronics package will look to the R.

The wide footpegs have removable rubber inserts. Ultimate Motorcycling and 1000PS praise the low seat, reassuring for shorter riders, but 1000PS finds the screen’s protection limited for taller riders. Ultimate Motorcycling notes vibrations through the footpegs at high revs and blurry mirrors, MCN levers that are not span-adjustable. The gross vehicle weight rating is 375 kg.
