I don't have an answer to your question Joost, I'm sorry, but I do have another question concerning the same topic, which I feel is best posted here: we too want to travel to Iran, with 2 motorcycles in june, and I have just read an article in last month's belgian magazine "motoren en toerisme" about 2 girls travelling by motorbike through Iran, and they had huge problems getting any fuel! Appearantly one needs a special card to get fuel, for the locals to a maximum of 100 litres a month, for tourists there is just nothing organized.. I don't know how recent or accurate this information is, does anybody know anything? Thanks..
