2020 KTM 790 Adventure

The dominant complaint pattern for the 2020 KTM 790 Adventure centers on the engine. Owners most frequently report unexpected engine shutoffs while riding, often at highway speeds and without any warning lights or codes beforehand. Cold-start difficulty is another recurring theme, with the engine requiring multiple attempts to fire when cold, a problem that returns even after dealer resets. Engine stalling during deceleration and downshifting also comes up across multiple reports. One owner describes premature internal wear on intake components at low mileage despite following the manufacturer's service schedule, though that appears to be a single report rather than a confirmed pattern. Two owners report fuel system irregularities, which overlap with the cold-start and stalling complaints. A single complaint describes rear shock seal failure leading to oil leaking onto the exhaust while the bike was transported on a hitch rack.
