KTM 390 Adventure Buyer's Guide

The Machine's Character

The 390 Adventure is built around a 373 cc liquid-cooled single making 44 hp at 9,500 rpm and 27 lb-ft at 7,000, fed by ride-by-wire and running through a six-speed with a slipper clutch. What lifts it above the usual small-adventure formula is everything around that engine: an upside-down fork with adjustment at both ends, a 320 mm front disc, a 19-inch front wheel, cornering ABS, KTM Motorcycle Traction Control and ride modes, plus a TFT dash, LED headlight and an adjustable screen. That is a full orange package sitting at the entry point of the class.

It rides the way a light KTM should. There is very little between you and the road, and the bike changes direction on thought alone, in a city block or on a fire road. It also stays cheap: roughly 70 mpg, small consumables, simple servicing. This is for the rider who wants a real adventure bike without the weight penalty and values access over bragging rights. The honest caveat is travel. With 6.7 in (170 mm) front and 7.0 in (177 mm) rear, it is a dirt-road machine rather than a hard enduro, and the 33.7 in (855 mm) seat asks something of shorter legs.

The Truth on the Street

None of what follows comes from my own test miles. It comes from years of listening: paddock talk, owners I meet at events, club nights, and the messages riders send me about bikes they own. On the 390 Adventure that feedback lines up tightly. The praise runs to how light and how well equipped the bike feels, and the complaints stay narrow.

Light First, Then The Hardware

Agility leads every conversation. Riders describe a bike that stays quick and honest in tight terrain, with a low fueled weight that keeps them confident when a trail closes in. Equipment talk follows. Cornering ABS, traction control and the color dash read as hardware from a costlier class, and the fork and preload-adjustable shock earn the same reaction for damping and adjustment range. The engine gets called tractable, with enough in the middle to sit at highway speed and enough manners for technical going.

Two Complaints That Keep Repeating

The pushback is narrow. Riders who work the bike hard off-road report the stock setup going soft under them and clearance running out, far enough to bottom it. The other repeat note is the seat. Owners call it firm and say it starts to tell on them once a day runs long.

Known issues

Stalling at low gears

engine occasional

Some owners report intermittent stalling when pulling away or maneuvering at low speeds, often resolved by an ECU reset or software update.
Gear indicator failure

electrics rare

A single report describes the gear position indicator failing at around 12,000 mi (20,000 km), requiring sensor replacement.

The Long-Haul Verdict

Forget spec-sheet bragging. Here's who the 390 Adventure is actually built for.

Aerial view of a winding asphalt road cutting through volcanic terrain on La Gomera, Canary Islands. The road curves through sparse green vegetation with rocky volcanic peaks visible in the background and a settled valley to the left. Clear lane markings, dry climate, partly cloudy sky.

Best motorcycle for Moab?

It's happy on graded dirt, gravel and mellow desert two-track. Push into slickrock ledges and deep sand and the 19-inch front wheel plus 6.7 in (170 mm) of travel run out before your skill does.

Best motorcycle for BDR routes?

Range and running costs are firmly on your side, and it's light enough to pick up alone. Plan on adding your own luggage, and accept that a heavy load on rough two-track asks a lot of the suspension.

Best motorcycle for Highway 1?

Twisty days are where it shines: lean clearance to spare, settled at speed, cheap to feed. On long interstate transits you'll feel the single buzzing and miss cruise control, which isn't fitted.

Alternatives to the KTM 390 Adventure

If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.

Any price note compares both bikes at the same age — the youngest age both have on the used market — against this KTM 390 Adventure. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
