Keep the bike at home, cold storage won't hurt it.
As others have said, full tank, fuel stabilizer, battery tender and, if you can, start it periodically.
I will add that after you add the stabilizer to run the engine long enough to get the stabilized fuel through the injectors.
I personally use StaBil in everything that sits over 3-4 weeks or so and it makes a huge difference in how the engine starts in the spring.
I have found that if I forget to put it in, say lawn equipment, then I'm cleaning and rebuilding carbs in the spring.
StaBil claims their product will stabilize fuel up to 24 months depending on the concentration used.

 

Like the others, I put the bike on a lift, cover it and store it in my non-heated WI garage. Since I have a carb, I also run the gas out of the float bowl and shut off the gas.

I forgot to add that I also remove the battery, put it in the basement on the battery tender.

Other than that....

 

Makes it convenient for when the ol lady kicks you to the garage, you can just grab you pillow and blanky and sleep on the bike.

 

Absolutely correct. That's the worst thing you can do to a bike. When I was younger, I also stored my bike over the winter. Now I'm old and crazy and ride all winter. There's no way I'm spending $35K on a bike and then store it for 4 to 5 months of the year = that's crazy.
What I did for storage was
1. Full tank of gas
2. Sta-bil or SeaFoam or ?
3. Clean/wax bike
4. Roll bike onto a large piece of corrugated cardboard or something comparable.
5. Hook up Battery Tender
6. Bed sheet or breathable cover over bike.
7. Zip tied clutch lever to grip. An old mechanic told me to do that many years ago. Personal preference.
8. If you have a lift-use it. Otherwise it's not going to hurt your tires leaving it on the floor.
9. Cover exhaust with a baggie or put steel wool in the end
10. Spray fogging oil into each cylinder
11. Put DampRid in saddlebags/tour pac
12. Lock it up real good
13. Change to fresh oil. You don't want that oil acidic oil eating away at the innards.
Yes, I went all out. Crazy huh? But I always had a great looking and running bike every summer.

Now I just ride. Salt? I ain't afraid of no salt!
I always spray down the whole bike(less rotors) with S100 Corrosion Protectant. Worth it's weight in gold-really works. Wash it off in March = spotless bike. Looks like it came off the showroom floor.
Wussies can't use that excuse for not riding in the winter anymore. Just admit it, it's too cold for you.

 

Gary Dyer added a couple of worthwhile points that no one else mentioned. I put some oil into the cylinders and turn the engine over by hand. He uses fogging oil. I just use motor oil. About 5-10 cc's worth. I also put sandwich baggies over the end of the mufflers with rubber bands. Prevents humid air from having a path into the cylinders. The air filter serves the same purpose on the intake side.

 

If you have room in your garage then keep it at home. I am very fortunate to work for someone who gave us a large area to store and work on our bikes whenever we want. Personally I would not store mine at home because I want the room for a car, truck and snowblower. I see no downside unless you want to work on it over the winter.

 

Last year I stored my pristine 2011 Fat bob at the dealer. The storage included an oil change. For some reason, they "had" to test drive it after the oil change and the rider went down on my bike. Yada yada yada - I traded it in on a 2015 SGS which I was planning on doing in the spring anyway. Moral of the story, I will be keeping the SGS in my garage this winter and every winter from now on.

 

It's fuel stabilizer not fuel restorer. It has chemicals that prevents the fuel from breaking down or degrading. Once degraded it's not going to bring it back. Ask anyone who deals with small engines about old, degraded gas and it's effects on those engines and carburetors. I am sure it has the same effect on our larger engines but not as apparent.

 

Store both mine with the dealer due to all the chunks of slush/salt splash falling off the undersides of the cars parked closely on either side in the garage. Been asking them to install a web cam so I can log on and check in with 'em during the winter....

 

I wouldn't start it and I would remove the battery and keep it in a warm place with a battery tender on it.
