I have a 2025 KTM 390 Adventure R with 4500 miles on it. Numerous times the E-throttle has lost throttle response mid-ride, the engine drops to idle and the check engine light comes on. After pulling over, I restart the engine and it works as normal. It has happened on the freeway and was difficult to pull over to the side to remedy the problem. I called several KTM dealers and they said they have never heard of such a problem. I researched the problem online and found recall #25v598 which was for 2022-2024 KTM 390 Adventure. It was for a faulty electronic throttle assembly which would lose throttle response mid-ride and the engine would drop to idle. It was exactly the problem I am having. It is very scary to be on the freeway when that happens.

Vehicle frequently stalls or engine stops suddenly. Engine will "knock" and suddenly stall when engaging the clutch while providing throttle to begin riding. It will stall when engaging the clutch to downshift into lower gears while coming to a stop. This has happened at busy roadways at red lights, stop signs, and even when slowing down to navigate a turn. Engine may stall while in neutral and throttle is applied. Typically a short rattle or what sounds like valves knocking, is followed by a backfire, prior to stalling. There is no way to prevent stalling/engine stopping unless RPM's are kept over 3,000. I have fallen over or crashed offroad several times, when navigating obstacles or negotiating tight turns or turn-arounds in the trails, dirt roads or forest. Bike stalled when attempting to navigate over a small log, resulting in bike crashing and pinning me underneath. Dealer performed update to most current fuel/mapping software but this did not make a difference.

The biked suddenly stalled in a traffic light. The worst part is that right after, when I click the starter to turn the bike back on, the whole electric system shut off. This had been a recurring issue, at least 7 times over the first 600 miles of this bike. I have an appointment to run diagnosis o the bike but have heard will be hard for KTM, to really take care and fix this. Please help. This became a large issue being stuck with cars honking on me. Had to get off the bike and push it off the road.
