This is disappointing. That’s pretty impressive. I bet the speed and gas mileage would suck on an actual working model though.

Not possible on a motorcycle. The track would get in the way of the basic lean angle geometry a motorcycle needs to initiate a turn on pavement. The snow is much more forgiving as it acts more like water and is really a 3 dientional surface to lean angles are much less of an issue.
