Thanks for the replies guys.

Culcune, what exactly is a motard? A certain type of dual-sport?

I went to the bike market here in Wuhan yesterday. I sat on a few dual-sport bikes. I hadn't realized how much the bike "sinks" when I sit on it, so that's encouraging.

I think the shortest seat was on a Shineray 150GY-B:

I could put the balls of both my feet comfortably on the ground.

Looking at Shineray's online catalog, the Shineray 150-17 also got my interest, because it's listed seat height is only 790 mm, as opposed to the 150GY-B's 870 mm. BUT, I wonder how accurate the specs are? I did some on-screen measurements with a ruler, and calculated (based on wheel-bases) that the seat heights of those two models are within 20 mm of each other. What gives?

I also talked to a dealer who was exactly my height and rides dual-sports as his hobby: he said he can ride any dual-sport without a problem. He also said that the seat heights on all models can be adjusted, but other people I spoke to said that's not true; and besides, just because you can adjust it, doesn't mean you should, right? I suppose there's a give-and-take: the high seat goes hand-in-hand with better suspension and ground clearance, no?

On a Zongshen 150, I could also touch the ground with both feet, but felt like I had to sit near the front of the seat (where it's lowest), which felt awkward.

In the Qingqi shop, the guys said they won't help me get a plate, so I just left.
