Thanks to the Chinese, you can now buy an Electric motorcycle in Thailand. These silent savers come in at 800 and 1200 watts. A charge of 6-8 hours gets you 70-80 km of travel. Top speed about 40 km/h. The model shown is a Vestor-b 2008 and runs 38,500 Baht. One that looks more like a Honda Dream comes in at 36,500 Baht. Check out the Vestor.
The only problem seems to be the main dealership is in Mukdahan.
