KTM 1390 Super Adventure R Final Review.

Fresh off the dusty, rugged trails of the 2026 Giant Loop Rally in Eastern Oregon, we have finalized our thoughts on the beastly 2026 KTM 1390 Super Adventure R. When you are covering endless miles across remote Pacific Northwest terrain, you need a machine designed to travel fast, carry plenty of fuel, and keep you comfortable. This heavy-hitting adventure motorcycle does exactly that, proving itself as one of the definitive 50/50 dual-purpose weapons on the market today.

At the heart of the experience is KTM’s legendary LC8 V-twin engine architecture. In a modern landscape where big-bore V-twins are becoming rare, KTM continues to refine this powerhouse. It produces an astonishing 160 horsepower and massive waves of low-end torque that get you moving instantly, making every twist of the throttle feel absolutely exhilarating.

However, the powertrain isn’t without its quirks. The older six-speed gearbox design can feel a bit sloppy, a lingering limitation of crankcase dimensions that have stayed relatively unchanged over decades of service. Fortunately, the seamless quickshifter rescues the experience, allowing for snappy, full-throttle upshifts and downshifts. Gearing is brilliantly spaced—first gear handles technical rock crawls with ease, while a tall sixth gear lets you cruise comfortably under 6,000 RPM at highway speeds.

Balanced Chassis and Agility in the Dirt

The physical balance of this chassis is outstanding, especially when blasting down fast fire roads. Carrying 6.1 gallons of fuel low around the flanks gives the bike a remarkably low center of gravity (CG). For a machine of this footprint, it maneuvers with incredible agility through two-track trails and even handles the occasional single-track diversion without breaking a sweat.

Stopping power comes courtesy of radial-mounted Brembo calipers paired with a premium radial master cylinder. The braking force is immensely powerful, yet the lever feel remains highly progressive, allowing you to modulate trail braking effortlessly on loose gravel. While you cannot disable the front ABS, the off-road calibration handles mellow to moderate terrain perfectly without early intervention. The rear ABS can still be completely deactivated for sliding the rear into corners.

Technology and Daily Comforts

Up front, the massive color TFT display is highly vibrant and features seamless touchscreen functionality for adjusting parameters. However, it feels a tad gimmicky; a slightly smaller unit could have easily trimmed down the bike’s premium retail price. The handlebar controls feature intuitive push-buttons for traction control and standard cruise control. Regrettably, at this price tier, heated grips are left to the options catalog—a feature that really should be standard on a premier long-distance tourer.

Wind protection from the broad front fairing is robust at highway speeds, keeping the rider’s torso protected without making the bike feel excessively wide like a BMW R 1300 GS Adventure. The windscreen could benefit from an extra inch or two of height, but it remains a highly effective shield. Riders will appreciate the toolless preload adjusters on the front forks, though we are left wondering why KTM didn’t extend that same tool-free convenience to the rear shock absorber.

Real-World Realities and Maintenance

The factory-fitted Dunlop tires offer excellent mechanical grip on mixed terrain, but the rubber compound is quite soft. Combined with 160 horsepower, expect to burn through rear tires quickly. Additionally, serious off-road riders should budget for heavy-duty aftermarket rims, as the stock wheels can be prone to bending under harsh square-edge impacts.

A minor trail-side headache involves the Tire Pressure Monitoring System (TPMS). If you get a flat and need to install an emergency inner tube, removing the internal sensor requires a Torx 10 bit—a tool surprisingly missing from the factory under-seat toolkit. Compounding this, our test unit failed to trigger a low-pressure warning on the dash when the tire dropped air, making the system feel more complex than it is helpful.

Where the Austrian manufacturer completely nails it is ownership longevity. KTM has engineered massive gaps between service intervals, turning this high-performance machine into an absolute low-maintenance workhorse.

  • Oil Changes: 9,000 Miles
  • Air Filter Replacement: 9,000 Miles
  • Valve Inspections: 36,000 Miles

If you are a rider looking to split your time precisely down the middle between long asphalt highway miles and aggressive backcountry exploration, the KTM 1390 Super Adventure R hits the sweet spot perfectly.
