The motorcycle becomes unstable and has a "death wobble". I purchased the motorcycle new from a Harley Davidson dealer and all service has been perform by the same dealer. The death wobble occurs at various situations including highway speed turns and straight high speed (~75-80 mph). This has occurred during calm and windy days. There was not rain and pavement was dry at the time of the incidents. The motorcycle continues to exhibit the "death wobble" at a variety of conditions not mentioned above, it is hard to guess when it will occur. I took it to the Harley Davidson dealer at ~200 miles and ~1,100 miles. The dealer reported that they could not reproduce the "death wobble". The dealer performed a test drive, checked the neck bearing, tire pressure and inspected tires. The "wobble" is not just an annoyance it is a true critical safety issue. I have also noted a significant number of other owners of the same motorcycle model/year have reported the same concern listed above. I urge the NHTSA to give a high priority in review of this safety concern. I have left the "Additional Details" section of this report blank as it occurred multiple times with the most recent being 8/4/2025 and the first being mid-May 2025. Basically, since I have owned motorcycle since new.
