I have ridden my old '86 Goldwing Aspencade in the snow quite a few times, usually on a trip and got caught in it. One day, and no I hadn't been drinking, I decided to take the Goldwing out in freezing rain, "just to see." I got dressed and ventured out, my then wife waited at home patiently, she was used to me by then. I rode the completely ice covered road behind my plan to the front of the plan, about 1/8 of a mile. I then had a choice, turn left uphill to go back to the house on the main road, or turn right downhill then do a u-turn on a flat section to go home. I turned right, turned around on the flat section, then once I got near the house had to turn and go downhill to the back road and turn right again to go to the garage. All the roads were 100 percent ice covered on top of frozen snow.
I made it without any issues, but I was beat when I got back. I also didn't plan on doing it again anytime soon. Surprisingly though, without making any sudden changes in direction or hard braking or acceleration, I never slipped. Still, don't want to do it on that big of a bike again, at least not on ice.
I run into a little ice at times when riding around Pittsburgh in the Winter. It is inevitable when it gets bellow freezing. I just ride a lot differently in the Winter than I do any other time of the year. I find I am more leery of wet leaves on the road in the Fall. In the Winter I just expect things to be slippery in places.
