On my 4 carb street bike I just try to keep the fuel on the fresh side by putting it up with a low tank and then I'll fire it up and go fill up with fresh fuel, tool around a little to get it moving and then repeat. If I do that once sometime in October and again in March/April I get by without issues, I've gotten away with it for 10 winters or so. This bike is a 4cyl with about 14:1 compression and 4-carbs so I would expect you'll be fine with lower comp and modern junk.
If the bike is not getting enough attention I'll siphon it's fuel and use it in equipment or my old jeep so I can have room in the tank for fresh fuel when the bike gets a chance. I've never used stabil or similar.
