I am looking to go from Bangkok to Chiang Mai in late december. Me plus my girlfriend on the back. From Google it looks to be about 750km. 10-12 hours strait through. Might split it up in 2 days. I'm an experienced rider, and she has been riding with me for about a year. I am looking for a place that will rent a motorcycle for the trip. I don't plan on returning to Bangkok. Can anyone give me some good direction to who would be able to do this?
