If you ask any of the guys at Ganesh Garden for a motorbike, they will have one brought over to you. Make sure it is not some old, beat-to-shit, cheap Chinese model with bald tires...you need some good tread on your tires on those sandy roads or you will wipe out. After I rejected the Chinese-cycle-of-death, They provided me with a new and perfect 125cc bike with helmets for 900 rupees (6 euros) per day. Aaahhh!
Generally speaking, wherever you are...just ask somebody working at your guesthouse and they will have a motorbike for you in no time.
