I don't like to stop riding. There are less safe and more safe times in winter to ride, and it is pretty easy to be comfortable to at least -16c.
I often pause my riding during the first snowfalls of winter, mostly because there isn't any salt on the road to take care of ice yet.
I used to try not to ride in actual snow beyond a light dusting. Sometimes.
I'm a big fan of Warm&Safe heated gloves and jacket liner, wearing long johns, and if you're doing several hours at sub-zero, breadbags over the socks inside the boots to act as a wind barrier.
I find I run into a frost problem inside my visor at -10c and below, despite an anti-fog pinlock. There looks to be some solutions to this from the snowmobile crowd but I haven't tried any of them yet. I saw a video where a guy ran some electrified wires through his visor to sort this out; ghetto but effective I guess.
Depending on your bike tire sizing, you might want to look into Heidenau K60 Sport Mud+Snow rated motorcycle tires (with the official snowflake symbol on them). petes-superbike and aviciouscycle carry them. They are intended to stay supple on cold roads (not that I've had a big problem with that with summer tires), and their tread pattern should offer some help when it comes to snow and slush.
I used Continental TKC80's on the CBR1100xx in winter, and was astounded at how good those things were on ice. My boots couldn't get traction at intersections and in parking lots, but the bike was pretty well planted. A gentle hand on the throttle and brakes, and never a drop.
Yes, you'll bathe the bike in salt. I've done this repeatedly to my Katanae 750's, gen5 VFR800, and my CBR1100xx without causing any big problems. You will likely reduce your resale value, in case that's important to you. I've seen steps recommended like hosing the bike down with WD40 before a ride, then washing it afterwards, etc; I never bothered. The crowns of the fairing bolts on one of the Katanae got pretty rust-covered, *shrug*. I usually look forward to the first heavy rain in spring to give the bike a nice cleansing shower.
