It's a 125cc Honda Wave one of the new model ones with the U-Box under the seat. Electric start, 2 years old with about 12,000km on the digital clock. Farang owned.
They sell new for 46,000baht in the Honda dealers and this one is 25,000Baht.
The 125 Honda waves are as good as you can get with the step through motorbikes. Message me if you want a picture.
