I can also recommend Vac Bag. I've used the same one for 10 years for my Tbird and it keeps the bike in perfect condition. I dry stored it at one point for 3 years and it was pristine. I keep it on the road for summer use. The Tiger is more robust (no bare alloy) so is ok with just a cover.
For cleaning spokes I use WD40 and a cloth. For alloy rims if really keen then alloy polish makes them shine better than new. Otherwise polish does a decent job. I find wiping the rim with a piece of paper kitchen towel after each ride to remove brake dust is worthwhile. It only takes a minute and stops deterioration. Probably not such an issue with chrome rims but alloy needs a lot of attention to keep it perfect.
