Having encountered ice once many years ago I now only ride when it's above freezing. My JR Ballisitic with a light jacket and thick sweater underneath works well. First Gear lined pants. Lined leather boots. And snowmobile gloves. All this works well for the 40 mile (each way) commute along I-15. I also run a plexifairing on my G which does a good job of keeping the wind off.
