Or take the battery off for the winter and store it indoors

actually that won't charge the battery, on most bikes the charging circuit doesn't become active until around 5000 rpm.......

remove the battery and keep it in the house

Not actually true regarding not charging.
To prove it, put a meter across the batery terminals with the motor turned off - you'll get about 11.5 volts.
Start the motor and run it at idle then meter the battery again - it'll show between 14 and 15 volts, assuming your charging circuit it working properly.

Even if you remove your battery and store it inside, a battery will naturally self discharge itself to destruction after about 3 months.

The best method bar none is to stick the battery on a battery tender (Optimate, Oxford, Accumen, etc ).
Don't use a 'trickle charger' as you'll run the risk of slowly cooking the cells.

Best method of all is to ride it on those crisp, dry winter days, as long as there's not too much salt about and put the grin back on yer face

The issue with starting the bike for a short period is twofold. First it takes almost ten minuites of riding to re-gain the charge lost through starting and second running the engine of short periods is bad for engine condition. As to disconnecting the battery, In my expierence a battery will last years sat disconnected as long as the ambient temperature is constant.
