KTM 390 Adventure years to avoid. The model years with the most complaints filed with NHTSA.

202512 complaints

7 of 12 describe the engine stalling, mostly when coming to a stop.

1 reported a crash.

The 2025 is still new, so its count can grow.

Recall 25V907000 (structure): Engine vibrations may cause the side stand spring to break and the side stand to fall to the ground.
Recall 25V825000 (engine and engine cooling): The engine control software may cause the engine to stall at low rpms, resulting in a loss of power.

After 2025, no model year drew more than 2.

Fewest complaints on file: 2020 (2), 2023 (1). Few complaints is not a clean bill of health, just fewer owners filing.

What each year's complaints describe comes from reading their text. These are counts, not rates: there are no sales figures per motorcycle model year. A complaint is not proof of a defect.
