I just watched your video. Either a bearing is bad, or the speedometer sensor is damaged. You should be protected by your warranty coverage; it's obvious this is a factory/dealership defect. Perhaps the dealership installed the front wheel improperly when they assembled the bike.
Once again, I advise you not to ride the bike any farther than the dealership until
after they diagnose, and
fix the problem. The should swap a front wheel assembly from another motorcycle, and send you away quickly as a happy customer. They can fix the bad wheel later, rather than make you wait.
