Occ, Thanks for the info. I'm planning on doing a tour this year, and I'm debating on whether to go on a formal tour...or just rent a bike and a guide..or no guide. In Thailand, I rented a Honda Transalp XV600 for US$12 per day, expensive by Thai standards...but not bad for a big bore dual sport. I had no guide, and just went off into the hills on paved and dirt roads. No problems - and I wasn't near the Laos or Cambodia border. You mentioned seeing many Honda XR250 bikes in Vietnam. I'm surprised...were these privately owned bikes? ...or tour group bikes? In the Philippines, only the relatively wealthy locals own a motorbike larger than a 150cc moped. I know there are some Vietnam tour groups using Honda XR200 bikes, a common and reliable workhorse in Asia.
