2026 KTM 1390 Super Adventure R Review: Epic California Desert Test Ride!

We take the highly anticipated 2026 KTM 1390 Super Adventure R out of the garage and hit the open road for an grueling 300+ mile test ride through the stunning high desert of California. From lane filtering through Southern California traffic to wide-open highway cruising and blasting down gravel roads in the shadow of the Sierra Nevadas, we put KTM’s latest flagship adventure bike through its paces.In this video, we break down everything you need to know about the 1390 Super Adventure R, including its torque-heavy $1350\text{cc}$ $75^\circ$ V-Twin engine, the massive vertical touchscreen dash with built-in eSIM cellular data navigation, and how that 9 inches of suspension travel handles both pavement and dirt. We also dive into real-world comfort, fuel economy (averaging 39-40 MPG), and how it stacks up against the mid-size KTM 890 Adventure R.What do you think of the new predator-style front end? Would you choose this over a BMW GS or Honda Africa Twin for your next cross-country trip?
