Winter sleep: what to check?

For those of us whose WR's hibernate through the approaching snowy months inside accessible storage:

What should be checked? What specific to our WRs should we go over?

I'm already planning to check: spark plug, air filter, all bolts & fasteners, spokes, bearings, cables, sprokets & chain, etc.

I'm not looking for how-to's, just 'check the doohicky wear/tighness/allignment/wetness/colour', or summat.

Nothing specific to the WR comes to mind.

On the Dual-sports I tend to like to repack the headset and swing arm bearings in the winter. Well, ok, I don't like to, but I feel it's a good idea anyway.

If I've ridden the bike a lot of miles that season or really hard (ie. track or off road) I tend to replace the fork oil (Ohlins 5W for all our upside down cartridge forks).
