Not sure to what you'd compare it to.
If you compare it to a roketa mc 05 127, or a Grom, both getting well over 100mpg, any bike will look poor in comparison. The first bike being geared very aggressively for higher mpg/lower rpm per mph.

The Vader 150 is quite poor in it's gas mileage. Granted, I ride it at 6k rpm most of the time, and get a solid 60mpg out of it, while it gets closer to 80mpg when keeping it between 3 and 5k rpm.
This engine should be able to do 100mpg easily at 40-45mph (doing ~ 4k rpm.
A lot of the China bikes have lower performance when they're:
a- Air cooled, and,
b- not fuel injected.

Mainly because they'll run a pretty low compression ratio.
If there was only an easy way to increase compression ratio on pushrod engines... Especially people in colder regions will benefit from this (higher gas mileage, same or better performance).
