Rode Chiang-mai, Wat Chan, Pai, return Chiang-Mai last week on a Yamaha TDM-850. Paved to near Mae Khan then good graded dirt to Wat Chan. North of Wat Chan 40 or so kms of rutted dirt road then a couple sections new pavement with dirt and constuction between into Pai. All in all not to bad, would not do it when wet though...About 7hrs round trip. Cheers Peter peter c.
