Hi,
My wife has got one she has had for a long time, i rode it with her on the back from Chaweng on Samui to Khao san road in Bangkok in two days, Pruchap KhiriKhan the first night, then Bangkok the second, then put it on the train with my wife to Udon and I went back to the UK. The bike performed superbly.
This was about 3 years ago and the bike wasn't new then and i still use it now when in Udon for little trips out and about, it also gets used by her brother everyday with no maintenance whatsoever except when I'm there and still never goes wrong.
