Hi, you don't need a VN licence to buy a motorbike. I already bought two motorbikes here and the shop owners have never asked for a VN licence. However, I had trouble with one of the shop owners since he was in the opinion that I would never get the motorbike registered here and thus, he refused to give my the red invoice which you need for the registration.
Furthermore, even the police does not care when you register the motorbike whether you are allowed to drive the bike or not. They never asked for the VN licence.
