I agree with LBV. We all have different standards and limits, and shouldn't be criticized for them. Despite recent efforts to the contrary, this is still a free world.
As for the conditions I ride in, I think most of you would agree that it's no more dangerous than summer driving, if you knew all the details.
First, I've never been cold. Fingers are never stiff.
Next, I have proper gear for warmth and safety, including a fog-free helmet and winter tires.
I ride a 30 minutes commute using country roads. No heavy traffic, but frequent traffic. I live on the edge of town and commute to a low-density populated city (if that makes sense).
I always make sure road conditions are good. My wife, strangely, has the same commute as I do but leaves two hours ahead of me. She warms me if the conditions are too harsh. I.e. snow-blown roads, strong winds, etc..
The only risk I see that may be higher is that other drivers are even more likely to overlook a motorcycle in winter. For this reason, I installed a Denali Soundbomb which sounds pretty close to a transport truck's horn.
My rules are: Dry roads only unless I KNOW the roads are salted, and even than I'm careful, especially on turns. No riding in snow. Always check the forecast for snow and rain.
Part of the reason I chose to ride through winter was to test my endurance and see if it can be safely done and tolerated. Turns out, I actually enjoy it! It's not as bad as you might think, and it's very enjoyable. I encourage anyone with the proper equipment to give it a go.
The thing I hate about riding in winter is the prep time for getting geared up: tape the pant legs, put on over-pants, tuck inner lining into the boots and tape that, put on jacket and zip it to the pants, buckle a strap around the waist to prevent draft. Oops, forgot the balaclava! Undo both layers of the jacket to tuck in the balaclava... Damn, l forgot to put the earbuds in. Twist the balaclava around to fit the buds in tight. Put on the helmet. Plug in the helmet. Put on the gloves. Oops, take off one glove to start the dash cam. Put on the glove. Go.
Fairweather riders can't even fathom that this is just what you do when you ride year round, and it's just normal, like doing up your shoelaces.
The having the wife do the same route ahead of you is very cool though. That's a lucky break. Definitely jealous of that.
