Now that's a different matter. You need your home country licence and IDP for the vehicle you're driving. If you have no motorcycle licence at home an IDP won't help you.
What! A policeman is going to look at your international licence and your home country licence and then demand to see your passport and then look for a visa, and then determine the type and then declare your international licence is invalid. Have you been to Thailand? Have you been stopped by the police?
