You can get them to shake also by striking the end of the bars. axel was checked front wheelbearings replaced changed fork oil . Also the front wheel is cupped.

Answer
Sorry to say, but I am not going to be able to help you. If you check my profile I only work on harleys. My best guess would be that you have a bearing in the steering head going out or you have a bad tire. Check with some of the other experts and they should be able to help.
Good luck and happy riding
Mike
