Notes:
1. No provision for passenger (fine with me actually); no rear footpegs.
2. Swingarm looks a bit thin, esp. for offroad stuff. Maybe not, but worth looking into.
3. Second video, 6 seconds in, shows the instruments.
4. Zonsen sounds like Zongshen; perhaps a different dialect of Chinese, i.e. not Putonghua (Mandarin).
5. Note that exhaust pipe dips below frame and engine guard. So a little caution is warranted there.
