FWIW... A few months ago I purchased an F650GS which was licensed in Phuket. It took 2-months of hassles to finally get my name on the green book. The problem was that Phuket and Pattaya use different forms for the Letter of Residence and neither province accepts the others form! I had to have someone intercede in my behalf to finally get the green book updated and in my name. I was informed that if were to ever sell the bike, the purchaser would incur the same problems I experienced, and was advised to change the license plate to my province of residence, Chonburi. Yesterday's trip to the Chonburi Land & Transportation Office resolved the potential problem. Along with the bike, I took photocopies of my passport, the green book and a new Letter of Residence, obtained from Pattaya Immigration. Initially, at the Transportation Office, a copy was pencil rubbed of the bike's serial number (like is done for annual license renewals). Then, I took this and all my documents to another office, where they processed the change of license. After paying 425-Bt, I was given a new tax/insurance sticker which indicated my new Chonburi license number, a new greenbook (which indicated me as the bikes' first purchaser; other prior owners names on the old green book were omitted), and upon handing them the bikes' Phuket license plate was given my new Chonburi plate. Painless...and it took about an hour and half.
