I'm a swedish biker and have earlier been in Chiang Mai traveling around on a rented bike. Now I'm going to Bangkok in february 2006 and have been in contact with Peter at Siam SuperBike. He seems to have reliable bikes for sale. I'm most interested in an offroad-bike. I plan to go from Bangkok to northern Thailand. An area I want to explore is the Thung Yai Narai Suan National Park north of Three Pagodas Pass. Have anybody made a ride through that area passing Nam Chon reservoir and up to Mae Sot? Thankful if somebody have some ideas about it.
