its a form of tank slapper yes but its a mechanical issue, it will pass an mot as they don't test bikes by riding them no handed, the issue could be one of many thinks, had this on my xj 600, was fine with my hands on the bars but after 30mph hands off my bars went insane! couldn't find what was wrong but after changing my front tyre it was fine but eventually starting coming back but not as bad.
Its probbaly down to your front wheel being off balance, get the wheel off stick the spindle through it and put it on a set of axel stands and spin the wheel, if it wobbles there is your issue.
it is perfectly safe aslong as you hold onto your bars, i rode like it for about 4 months before i fixed it but i didn't set out to fix it.
