I kept my T100 outside for nearly two years & use it in all weathers - not a single problem.
The main thing is to keep it under a cover & to have an alarm so you can hear if it is knocked or anyone tries to move it. A good cover is one of the best security devices you can get. Get one with a strap to stop it blowing off, or use a tie-down over a normal cover. I lost two Oxford Rainex covers to windy days before I sussed that out ! Luckily they are cheap on eBay
If you take care of the chrome there will be no problems. A session to clean the bike and wipe over on the chrome with a chrome polisher every month or so is a nice way to unwind for a couple of hours and get to know the bike better at the same time.
As for rust, it will happen. As part of the battle I'm about to try out ACF-50 to prevent corrosion, it is supposed to stop corrosion forming on aircraft and be safe for bikes.
Just go for it - and insure it fully comp, just in case
