They advertise that bike with a 163FML, if you go to the Yingang site and check the engine specs, you see it is actually a 205 version. With a 63.5x65 bore and stroke, the cubage is actually almost 206cc.
They rate it with 11.5kw @8000rpm that’s 15.65hp. That’s not bad.
Yingang also has a 169FML that is an over head cam that has 16.32hp @9500 rpm. Its only a 198cc a bit smaller but also bit more powerful.

If you like these bikes, your in luck it seems they are importing allot of them, in a variety of models and most with the 163FML also two models with the 170mm, that is a powerful 250cc with nearly 26hp. (NX250)
Get the model codes and google them it is the best way to find them…..
