I put mine away during winter also, more because its simply just too dangerous.
I live in a rural area commuting in to a city, country roads, no street lights, dark, its just a nightmare, when cars go past you, you get completely blinded for a split second or so when all the rain drops on your visor reflect the cars headlights. Added to the fact that rural vehicles drop tones of deisel and manure and all other manor or crap on the road, which you might not easily be able to see. Just not worth it.
I did it for 6 months one year out of necessity and thinking to myself if I keep doing this over the years at some point I am going to end up having a ****** up day (as cyclecruza says - FYI google that guys youtube vids).
With mine I jsut brim it (as already mentioned) also whack a bit of redex in the tank and give the bike a jiffle around. I give it a damn good clean before it goes away and cake it in Scotoiler FS365 which I prefer to ACF50 for storage. I dont use a trickle charger though I just start the bike up every few weeks, get it to temperature and run it for about 15 mintues or so, been doing this for years with no issues. I did read somewhere saying that isnt the right thing to do and went in to some explanation as to why, but I think a lot of that is subjective and not something I agree with personally. Not that using a trickle charge is a bad idea though, I should add.
