Great thread! As I was looking at the pictures, I had a feeling that I've seen this bike before, or something very similar to it.
One of my favorite bikes from my younger years that I could never afford back then, the Honda XR 125 L. That bike had the CG125 OHV engine but no fuel injection.
I think they were never sold in the US.
And compare the Lifan.
I think these are pretty much the same bike!
