This page covers 4 recalls and 12 owner complaints for the 2019 KTM 790 Adventure.
Brake-related complaints dominate what owners of the 2019 KTM 790 Adventure report. The most consistent pattern involves the brake light switch failing, with multiple owners describing a brake light that either doesn't illuminate at all during normal braking or requires unusually heavy lever pressure before it activates. A couple of owners also note wheel-related issues, though those reports lack enough detail to identify a clear pattern. On the engine side, isolated reports describe hard starting, stalling at low speeds when throttle is applied, and at least one account of an oil pressure warning triggering at higher mileage leading to a dealer inspection. A single report describes the wet clutch running dry and slipping badly, though that appears to be an isolated incident rather than a recurring theme.

Total Complaints
By System
Recalls 2, 3, and 4 describe the same two underlying defects as Recall 1 — I'll treat these as two issues total (rear brake hose overheating, front brake master cylinder spring).
The 2019 KTM 790 Adventure has 2 recalls, both affecting braking: the rear brake hose can overheat under hard use and fail completely, and the front brake master cylinder has a weak return spring that causes a long, soft lever pull before the brakes engage.
When the rear brake hose overheats and fails, the rider loses all rear braking and must rely entirely on the front brake to stop, significantly extending stopping distances. On the front brake, the return spring inside the master cylinder may not push the brake piston back far enough after the lever is released, so the next time the lever is pulled it travels an unusually long distance before any braking force builds. Both issues raise the risk of a crash by reducing the total stopping power available, particularly in situations where the rider needs to shed speed quickly.
At a glance
What can fail
The front brake master cylinder's return spring is too weak, so the brake piston may not fully reset when you release the brake lever. This causes a long lever travel before braking engages and reduces braking power.
