I was looking at some bikes down town 400 CC to 1200CC great bikes, good prices but not one with a book.
The lady at the shop told us no problem as long as you stay in Thailand. Met a farrang there who said he had been running without a book for ten years three diferent bikes and never had a problem, But it sure makes me nervous. We are not talking about a few thousand Baht here. Supposedly they can get a book for 70k but you could tell they really didn't want to.
