Hey. I actually just asked this question in the dual sport thread. The answers are there but here is the tldr:

1. Buy a Japanese bike made in China. The YBR250 is the usual recommendation.
2. If you really want a China bike, you have three options >250cc and many options <250cc.
3. Larger than 250cc, look at jialing JH600 (sport touring), Shineray x5 (adv dual purpose), or a CFMoto650NK (street)
4. At 250cc, you have a large assortment of utilitarian dual purpose bikes with few features and many cheap parts. Worth mentioning is the Zongshen Rx3.
