Phlash,
Hello and Welcome. It can be done.
I have been riding with some friends and temps were around 40. Well, I was okay, but a little chilly. I mentioned it to one of them when we were stopped and he said "I just plug in" He proceded to tell me about Gerbings heated clothing. They all had it.
I went Monday and bought the heated gloves and jacket liner, attached the plug to my bike in about 15 minutes and went for my first ride, "plugged in". Holy Moly what a difference. I could not believe how warm I was. It was 28 degrees, I was on my Fatboy with no windshield and was toasty warm at 70mph. I was so happy.
The stuff is a little pricey, but is well worth it. I got mine at the local BMW dealer as they had the complete line in stock. I also got the dual temp controller which allows the gloves to be at a different temp than the jacket. I needed to turn them down, they were that warm.
Still have to watch out for black ice and know that the tires don't have the same grip, but as far as being cold, it is a thing of the past now.
Good Luck
