you could put knobbys on a light dirt bike and ride in the snow - better if its off road and not on slushy pavements
putting sheet metal screws in knobby tires and racing on the ice is an actual sport
in general, the problem with riding a motorcycle on the streets in snow and ice, is that MCs are self balancing while the wheels are spinning. If you dont believe this get your bike up to 40 mph and lock up the front wheel/brake. The bike will fall down so fast throwing you over the handle bars you wont know why you are suddenly lying in the street.
Its very very easy to lock up the brakes on any vehicle in the snow - that the real problem. On a light dirt bike you can keep one foot down most of the time, like you are power drifting in the dirt or mud, but it would be exhausting, because you would be holding the bike up with one foot or the other most of the time.
In WW2 BMW made a motorcycle with a side car that had a shaft drive to both rear wheels. It was unstoppable in the snow, better than our Jeeps. Likewise, police departments use 3 wheel motorcycles for funeral escorts year round up here in NY.
3 wheels is good. Two wheels is exhausting.
