Buying a pure dirt bike is not so difficult in Thailand, you have several motorcycle dealers in Bangkok who can import a Suzuki motocross bike for you... They import them as parts and rebuild the bike after it arrives in Bangkok, for dirt bikes this is not a problem as a greenbook is anyway impossible to get...
