I have left my supermoto out during below freezing temperatures and it was fine. Before I got a house I had it outside all year for 5 years, no battery tender or anything. And its still running strong on the original battery.

The only thing I would do is make sure you have good coolant. And if you don't want to start it every once in a while I would pull the battery out and put it on a tender, or charge it once a month. I usually just start my bike once every other week and let it run for 10-20 minutes.
