Very similar to the Rokon which has been made here for years.

I think this Russian bike is powered by an internal combustion engine as a haze of blue smoke can be seen in one spot. A two stroke perhaps that would explain the light weight. I would guess 125cc or less with very low trail gearing from the size of those sprockets.
