The Enduro Name Fully Earned
The 390 Enduro R is built around a 399 cc liquid-cooled single making 45 hp and 29 lb-ft, tuned for pull through the middle rather than a headline peak. What lifts it above the usual small dual-sport is everything wrapped around that engine. You get a fully adjustable USD fork and shock with 9.0 inches of travel at each end, 10.7 inches of ground clearance, a 21-inch front and 18-inch rear on a 6-speed chain drive, plus a real electronics package: Bosch ABS, KTM Motorcycle Traction Control, Ride-by-Wire engine maps, and a TFT display to run them.
It rewards momentum instead of punishing mistakes, which is the whole point in technical terrain, and the long travel lets you ride a sloppy line without paying for it. That makes this the orange bike for a rider who wants genuine off-road capability without a race-machine learning curve, and it takes hard parts and upgrades well as your skills climb. The caveats are plain enough. Seat height is 35.0 inches, so shorter riders will be on tiptoes in a rutted section. The 2.4-gallon tank keeps your loops honest. Wet weight of 364 lb is light for the job, still real when you pick it up.

The named systems that set this bike apart — and what each one does for you.
Braking
Rider aids
What follows isn't my ride. It comes from years of paddock talk, owner conversations, club-night chatter and the messages riders send me directly. The pattern on the 390 Enduro R is clear: owners describe a friendly, road-leaning dual-sport more than the hard enduro its name promises.
The strongest praise is about how approachable it is in the dirt. Less experienced riders talk about smooth power delivery and suspension that builds their confidence. The single gets credit too. It has enough for the highway and it's happy to rev, with a top-end rush that owners enjoy. Many also mention how much equipment they get for the money.
The complaint riders repeat most is vibration. It reaches the mirrors from around 5,000 rpm, the bar by 6,000 and the pegs past 8,000, and long highway stretches get tiring. With no screen or fairing, wind blast makes it worse on road trips. Some riders expected a harder-edged off-roader and were disappointed. A few owners also say the bike needs frequent downshifts in technical sections, and that the stock suspension bottoms out on bigger hits when it's ridden hard.
Side stand spring may break
Engine harmonics can cause the side stand spring to break. If the side stand falls while riding, the ignition cuts and the stand may contact the ground, leading to a crash risk.
ECU software defect causing engine stall
A recall has been issued to update the engine control unit software because a defect can cause the engine to stall at low rpms, increasing crash risk.
Turn signal malfunction in cold temperatures
Several owners have reported that the turn signals stop working in cold weather. The issue appears intermittent and may be related to a sensor or relay.
Loose battery terminal causing intermittent no-start
Some units have been delivered with insufficiently tightened battery terminals, leading to sudden electrical cut-outs when attempting to start. Tightening the connection resolves the problem.
Where this KTM 390 Enduro R pulls ahead of — or falls behind — its rivals on the numbers, and the typical bike in its class on character.

Forget spec-sheet bragging. Here's who the 390 Enduro R is actually built for.
This is your bike. Light enough to place precisely on slickrock, suspended well enough for sand whoops, and honest in the tight stuff. Plan your day around the 2.4-gallon tank and you are set.

It will handle any BDR dirt you point it at and thank you on the hard sections. The limit is logistics: a 2.4-gallon tank and a 35.0-inch seat make long transit days and fuel gaps your main planning problem.
Made for Arizona Backcountry Discovery Route · Southern California Backcountry Discovery Route · Colorado Backcountry Discovery Route
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 Enduro R. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
