2026 KTM 1390 Super Adventure R Street Review

Chasing dirt, twisties, and rallies on KTM’s flagship.

Few things stir the soul of a hardcore adventure motorcyclist quite like a massive V-twin, a six-gallon fuel tank, and a horizon cutting right through the American Southwest. If you are looking to obliterate highway miles and conquer rugged fire roads back-to-back, the 2026 KTM 1390 Super Adventure R arrives with a roaring statement.

To give this behemoth a proper shake-down, we loaded up our gear and hit the blacktop and dirt corridors of California, logging a grueling 300-mile highway stint before packing it into the chase van bound for the legendary Giant Loop Rally in Eastern Oregon. Through city filtering, open high-desert terrain, and aggressive mountain twisties, the 1390 R proved that KTM’s “Ready to Race” ethos is alive, well, and packing some serious muscle.

First Impressions: A Predator in the High Desert

Visually, the 1390 Super Adventure R demands attention. KTM has reworked the front end into a striking, vertical-stack “Predator style” aesthetic. It feels slightly softer and more neutral than its predecessor, blending aggressive angularity with improved airflow engineering.

Swinging a leg over it is your first reminder that this machine is built for the dirt; the seat height is unapologetically tall, requiring a bit of flexibility to mount. Once in the saddle, the ergonomics offer a commanding, “lifted truck” presence over the road. You sit high, looking over standard SUVs and scanning far down the pavement.

Interestingly, despite housing a narrow 75-degree V-twin, the midsection doesn’t feel quite as skinny as you’d expect. It isn’t absurdly wide, but compared to some competitors in the heavy adventure segment, it retains a solid heft. The footpegs are beautifully grippy and positioned right in the sweet spot. For street riders, the handlebar features a conservative bend with a comfortable rearward sweep. However, when transitioning into an off-road standing position, taller riders might feel the bars sit just a hair too low.

Powertrain Perfection: A Pussycat with Real Muscle

If there is one crowning achievement on this motorcycle, it is the updated 1350cc V-twin engine. It is incredibly flexible. At low RPMs, the bike behaves like an absolute pussycat—smooth, predictable, and remarkably easy to manage. But when you decide to “give her the berries,” the engine responds with startling urgency.

During our highway acceleration test, rolling open the throttle unleashed a wave of torque that easily pulled the front wheel off the tarmac. Getting onto Southern California freeways at 80+ mph is effortless, and despite pushing a massive displacement powerplant, we averaged an impressive 39 to 40 mpg. For a six-gallon long-range cruiser, that efficiency translates to immense range out in the sticks.

Vibration is an inherent trait of a large-displacement 75-degree V-twin, and you will feel a distinctive buzz through the pegs and bars. However, KTM did a masterful job with engine damping. Instead of an annoying, numbing buzz, it functions as a mechanical heartbeat that makes you feel alive in the cockpit.

Tech, Navigation, and the “No (Standard) Heated Grips” Conundrum

The command center of the 2026 model features a stunning vertical touchscreen dash that behaves exactly like a modern smartphone—even with heavy riding gloves on. Thanks to an integrated ESIM card, the motorcycle features standalone cellular data service. This powers a gorgeous, highly responsive, full-screen moving map with turn-by-turn navigation directly on the dash, completely eliminating the need for a separate GPS unit.

Through the menu system, riders can seamlessly toggle between Street, Sport, Rain, Off-Road, and Rally ride modes. Digging deeper into the electronic aids, you can customize:

• ABS: Road and Off-Road settings.
• MTC & MSR: Motorcycle Traction Control and Motor Slip Regulation (Sport or Off).
• Engine Braking: Adjustable from +2 to -2.
• Quickshifter: Flawless, clutchless upshifts and downshifts under full throttle.

However, the tech suite isn’t without a few head-scratching omissions. As our journey took us into the higher altitudes of Lone Pine and the Mercury began to drop, we went digging through the menus for heated grips. Shockingly, they are absent. On a premium, $20,000-plus open-class adventure bike designed to cross continents, having heated grips hidden away as an optional PowerParts accessory—when mid-tier bikes like the KTM 990 Duke feature integrated display options—feels like a massive oversight.

Additionally, while the on-board navigation is brilliant, the processor can feel a bit sluggish, taking a second or two to recalculate when manipulating waypoints.

Road vs. Dirt: Where It Belongs

As we carved through the Alabama Hills—a historic Hollywood filming location famous for its striking dual-density mountain layers—the 1390 R showcased its dual personality.

The undisputed highlight of the pavement test was the mountain twisties. The chassis geometry and cornering manners are impeccable, making it feel far lighter than its spec sheet suggests. The standard windscreen does an adequate job of deflecting air, but the overall front fairing is incredibly narrow. KTM’s heritage as a dirt bike company shines through here. Ironically, the mid-sized KTM 890 Adventure R review actually offers a broader front fairing that blocks crosswinds better than its larger sibling.

We also tested an aftermarket KTM PowerParts tall rally seat on this journey. While it adds extra ground clearance, the rounded center hump proved less comfortable for long-distance highway touring compared to the stellar stock seats found on previous KTM builds.

When a highway detour forced us onto a rugged off-road track, the 9 inches of long-travel WP suspension completely ate up the terrain. It soaks up hard ruts, rocks, and washes with total composure, proving that this bike isn’t just an “adventure tourer” in name—it is a legitimate dirt weapon.

The Verdict

The 2026 KTM 1390 Super Adventure R is a masterpiece of mechanical flexibility. It behaves like a civilized touring bike at low speeds, transforms into a superbike on twisty asphalt, and tackles rugged terrain like a oversized enduro. Keep an eye out for our upcoming coverage as we take this beast to the next level at the Giant Loop Rally in Oregon.
