In November 2011, I rode my Thailand registered Yamaha FJR from Bangkok to Singapore. My bike is financed in Thailand, so I do not have a green book. The finance company provides me only with a copy from the book which shows that I have the right to possess and ride the motorbike, but it is registered in the name of the finance company. I had no problem using that paper to depart Thailand and enter into Malaysia and subsequently into Singapore, without any hassles. Now I want to ride to Phnom Penh. Has anyone tried to cross into Cambodia from Thailand with only a copy of the green book as I have?
