There is cleaning and cleaning, cars can cope with a bucket of warm water a month as everything is really designed to be covered in crap, its only the outside most of us wash.
Relatively speaking your needing to do the equivalent of jacking the car up and removing the wheels and bonnet then cleaning all you can see.
I don'nt ride my bike from October to March, I don't care what you say it shags bikes and riding in all that winter crap and cold is shite too. I have done the only transport thing though before you start, 4 years my old 600 Suzuki was my sole transport.
I became expert at stripping and cleaning the brakes, not disturbing and lines just undo the caliper. Then brush and soapy water to wash the caliper and push the pistons out and back so they were free. Same with the rear, lost 2 rear calipers before keeping the monthly ritual. Scottoiler, cannot stress this one enough as well as getting a good quality stainless steel exhaust, (good excuse for an upgrade). Lastly have the garden hose ready to go, mine was rigged in the garage so it didn't freeze too much. If the hose is too much hassle to get/set up you wont use it. Just rinse the bike down after each ride. Don't get too excited with a cover as wet is fine, as is dry, without the cover the wind will dry it off quickly. Its the nasty middle ground of being left wet in a damp garage that does damage.
Lastly lots of wd40 on the electricals and change the plug caps at every other plug change and she will never miss in the rain.
