From owner reports, verbatim
I purchased a 2024 KTM 390 Adventure on June 21, 2025 and within 1/4 mile of driving it away from the dealership my throttle completely cut out as I was merging into traffic. The bike had 2 miles on it and was brand new. I turned the key to the bike off and back on after I was sitting in the bike lane of the road. I started the bike back up and was able to make it another mile down the road when my throttle completely cut out as I was making a left turn through an intersection. I rode the bike immediately back to the dealership and explained the situation. They said they hadn’t heard of anything like that before and had their mechanic inspect it. They confirmed the bike had a short in the e-throttle and gave me another new 2024 KTM 390 Adventure. I received a recall in September 2025 about the known issue of the throttle cutting out and that my current bike is one of the affected VINs. I am writing this complaint because KTM has not come up with a remedy in a timely manner. I don’t feel safe or confident riding my bike knowing I could be injured or killed if the throttle cuts out on me at the wrong time.
