Motorbike riding just happens to be something I personally have allot of experience in, and I never seem to tire of it. In Thailand motorbike is a major source of personal transportation. For my transportation needs here on the island a motorbike is perfect, the roads are just too narrow for a bigger vehicle. Also my fossil fuel consumption is about two liters a week whereas before in the states it was fifty times that conservatively speaking.
Motorbike rentals are widely available on the island. All of the motorbikes for rent here are all late models and are well maintained for your riding pleasure and safety. Most of the motorbikes have automatic clutch, with some even being fully automatic, so you don't even need to shift gears. The cost is around 300bahts for the entire day with rates going down to about 200bahts after 2pm. For exploring the island motorbike is the way to go. A map of the island is supplied with each motorbike. There are many road signs written in English, on the island that should keep you from getting lost. If however you do get lost it won't take you long to find your way again, the island is not that big.
