If you're bike's in a garage, you're golden. Just ride it when the roads are clear. It can't hurt to put Sta-bil or Sea Foam in the gas, just in case it ends up sitting for a month or two.
When I lived in Brooklyn I used to ride the bike to my parents' place in CT in early December, winterize it, store it in their garage, and put it back on the road in March or April. I was glad I did that the one or two times we had major snow storms and snow piled up between the cars. That would have been really bad for the bike. But otherwise, NYC winters are mild enough that I would have ridden year round if only for slightly better parking protection. With good wind breaking gear and base- and mid-layers, I was fine riding in temps as low as the mid-20F range.
Now I'm in Oklahoma. Last "winter" it rarely dipped below 50F, which felt very unnatural to me. I rode year round though, which was nice. Will be interesting to see what happens this "winter."
