What owners report

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.
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.
