While commuting to work on 5/26/26, around 5:30 am, I felt my vehicle decelerate, and the throttle became unresponsive. I shifted into neutral and coasted for a little while, working the throttle from limit to limit to feel its responsiveness. After a few cycles, it seemed to be acting normally. If I had reacted differently, been going faster, been in the middle of negotiating a turn, or a complex maneuver, this could have ended badly, resulting in me dropping the bike, potentially causing property damage, injuring myself, and others. No warning lights or messages were displayed regarding this issue. I have dropped off the vehicle at an authorized service center on 5/28/26, after finding recall information online about throttle issues. I am not aware if they could recreate the issue. This only happened once, on that day, I continued commuting on the bike until dropped off for service.

What 2024 Ktm RC 390 owners say
Most recent owner complaints, unedited.
I purchased the motorcycle March 27th, 2026 and was told that I would receive it within a week. Then had to call KTM on April 15, 2026 and was told by a representative that it would be another week to receive the part. The following week came by and was told it would be another week or two. Two weeks have passed and now they have absolutely no answer as to when my part will be available. This has been a total of six weeks since purchasing the vehicle and I cannot even drive it as it was issued a recall the day after purchase. I am out of pocket $7000.00 and I have zero answers as to when I will receive it. I do not fault the dealership for selling it to me and I was given opportunities for a full refund but as it was difficult to get this motorcycle as is within my budget. I am without transportation as long as this issue continues. I am walking miles to and from work every night. I already received the title and the license plate for the motorcycle before I have even started it, which is unheard of.
