Yeah, looks like you have an Almax there- great chains but you may as well just use a disclock if you're not locking to anything. My KTM 990SMT had an Almax, alarm and two disc locks, but was nicked as mentioned above- they just picked it up and dumped it in a van
Difficult as the area only has one bike space with a rail.
Also controversial I know, but I wouldn't bother with the steering lock. Thieves will break it in 5 secs and it'll damage your frame.
Consider the 2.5m Almax and a topbox, that's how I cart mine around. And two disclocks, and two trackers. And a cover, as already said if they can't see it they probably won't bother with it. I've had three bikes nicked now in London, so I'm not taking chances any more.
