90% of Norway are secure parking for 90% of the bikes =
99% of the BMWs are safe, but not 99% of the HDs...
...but don't worry; if you hook those two bikes together not a soul would nick any of them as a HD-thieve would never touch a BMW or the other way around!

... but no guarantee from me...
Honest:
They do nick bikes over here too, and make them tilt. But often when I hear the story about how&and type of bike that are nicked, these are typical:
-No lock or only one disc lock at the front wheel, no chain.
-In a garage, shed, on the street; -it seem not to matter much as it seem like they know what bike they want.
-BMWs was not popular before, but now they are getting nicked too, but again not as often as fast jap&italian bikes and HDs.
-Tilt/damage when parked: Not often, and not on purpose.
-Goodies that needs screwdriver to remove; -I've never heard any has lost any thing that way when parked.
It's better to park it a place many people can see it then on the back as the thieves does not like to be seen when they are at ''work''.
Next to a disco? Drunk people do things, but on the other hand there are guard/Police keeping an eye on places like that, so... a place so all can see it but not where it's too crowdy with drunk people is the best?
