Scoots in Vietnam
Many nice pictures in Lost in Transportation, an article written (in English) by Denise Lejcar in OhmyNews (Korea). Most of these are what people call "motorbikes" in Southeast Asia and "mobylettes" in much of Africa (although I think a mobylette is really a moped, while the SE Asian bikes do NOT have pedals).
They average about 100cc and have bigger wheels (16-inch) than most of the scooters sold in North America. All are single-cylinder. Some are two-stroke and some are four-stroke. I like them!
