Can you clarify, does that apply to private sales of used vehicles as well as dealer sales in Michigan? (Some states don't tax private sales.)
When you register a private sale, they ask for the sale price, and you pay tax on that. If the product isn't registered, then of course no tax is required. But sleds need to be registered and SOME atv's get titled boats get registered, and all of those you pay a tax. If you transfer to an immediate family member no tax is due. Otherwise, you pay 6%. If you lie and say the price was well below market value, they have an investigative team that works on those to farret out guys who cheat and there is penalty and the tax to be paid once the "rest of the story" is found out. I think all new ATV's come with titles nowadays, so no avoiding tax. But since atv's don't have plates once it is used, no tax or registration is due and you can just pass it around from there on, unless you want the title to be transferred with the sale.
