Step 1) Ride to your local refuse center Step 2) Turn the bike off and step off it Step 3) leave the bike and catch a bus. I kid, but seriously with mine i spent a lot of time working on it and still never kept it in that good nick. First off get yourself a good cover for when it's not in use, rain is your arch nemesis. Second if you have chrome, get some autosol and polish that shizzle, polish it reeeeeal good. Give it a nice protective layer of polish. Third, get some ACF-50 and spray it on a cloth and wipe it over your engine and other metal parts (not brakes) Fourth, clean the bike weekly get any salt, dirt,general crap off. As for the chain, I have started using Parafin (B&Q £6 for 4 litres) and brush it on with a bristly brush and wipe it off with some rags, spot less. Then apply some lubricant everyone has their own preference, I still use muc-off dry chain lube. Before you apply it, warm the chain up by running it a little then spray it all over the o-rings and cover the lot. be careful it doesn't land on the wheel if it does get it off or you might slide about on the bike. If you get rust, scrub it off and cover it early, it will only get worse. I think that covers it all.. Good luck is all i can say.
