“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.”
NHTSA complaint #11693187, filed 2025-10“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. …”
