Orionengnr, just curious where are you located. I have a friend here in lovely Dayton, OH that rides almost everyday. He has a blog Moto Adventure. I'm sure he would like to here from you. He is always interested in riders like yourself who do not use four wheels. The blog web site. https://motoadventurer.com
Yes, ice is the key risk factor. I am about to break my streak, after 30 years without owning a car, because I'm spending this winter working in Minneapolis, MN. (Next week, I'm flying back to NH, and buying my ex-wife's 2002 Mini-Cooper S, as my winter/bad weather car.)
Most of that 30 years, I lived in San Diego, so winter was not an issue. But 7 years ago I moved to NH. I rode every day for 8-9 months a year in NH, and occasionally even in the real winter if the roads were dry, on my trusty 1993 M900. The first winter I was in NH, I rode right through the winter, since it only snowed twice that winter (2011/2012). (Other winters, I shared my [now ex-]wife's car when it was actually icy out.) I just got heated gloves, and rode on. Lots of riding at about 20F (-7C), which, with the heated gloves and decent layering otherwise, I could do for about an hour at a time without undue discomfort.
I'm now traveling for work, so I've ridden through the winter in a number of places. Mostly from St. Louis on down. I did spend the winter in Cleveland once, and I had to put the bike away for a couple of months and rent a car. The coldest I've ridden in was about 25 minutes at 5F (-15C), and that did indeed feel cold.
I know people who have ridden through the winter in NH multiple years. Usually, the drill for them is something like: Suzuki V-Strom, knobby dirt tire on the front, darkside car snow tire on the rear, and heated gear all over. It can be done, although that is just slightly outside my comfort zone.
