Hi chefmv,
No problem if your garage is cold, as long as it's dry. I would do the following, I'm sure I will have forgotten something so a few suggestions from other members would be welcome
Drain Fuel from tank and carbs (VERY IMPORTANT!)
Disconnect Battery, if possible leave it somewhere a little warmer like inside the house.
Change Engine & Gearbox oil (the nasty contaminates in used oil are acidic)
Change hydraulic fluid (the brake fluid is hydroscopic, so it absorbs water)
Leave the bike on the centre stand and over inflate the tyres. This will avoid flat spots on the tyres.
You might want to give the chrome, bare alloy and steel a good coating of WD40 (just remember to clean it off when you return)
Cover the bike with a breathable cover to keep the dust off, don't use one of those plastic covers as they tend to keep the moisture in.
That's all I can think of, I'm sure some of the guys out there will have some other suggestions.
