Drain the coolant tend the battery ( only tend the battery one day a week) put seafoam in the gas an run it thru the motor ( before you drain the coolant) don't let your tire pressure get terribly low but spec isn't necessary. When you take it out of storage it is very important the motor does not start for several revolutions, I think its better to have the stabilized fuel in the motor and fuel system for storage but you really don't want it to fire up when you first crank it over because the motor will not be lubricated as the oil has long since settled, I personaly would disconnected the spark plugs prior to cranking.
I don't store my bike I just ride it all year. But my family has many project bikes that are stored much longer than a winter and all is well. Just remember coolant is corrosive, gas turns to laquer and gunk, and oil settles to the bottom leaving the pistons dry. I'm sure others will add more to this.

12,000 miles and some-days it still scares me.
