I am arriving in Greece on a tourist visa, my parents' house is here, I also have an AFM. I want to buy a bike to go grocery shopping and to the beach. As far as I understand, mopeds up to 50cc do not need to be registered, but do they need insurance? Tell me, can I buy a moped up to 50cc and not register it here? Were I able to complete the transaction and what do I need for this?
