Each to their own, of course. You have a better idea of what's safe for you.
That said I live in a snowy country and ride a bike. I absolutely wouldn't ride a motorcycle. Speed is by far the largest reason. On a bike, you can see black ice before you hit it. You can run a foot along the ground for extra traction. You can get out and walk and push your vehicle. You can just jump off if shit really hits the fan.
That said, I also ride slowly when the roads are poor.
