Yes they are. As it was snowing horridly last night, I left mine on Zurich Bahnhofstrasse - where the road is paved with gold - and someone has obviously been interested in it.
To the point where they've managed to flatten the battery.
I assume highbeams come on without keys inserted? Trip meter also reset - but I don't think that affects my battery
So I wait for the man with the cable to stick into my socket
I now retract my statement of hating the person who touched my bike. They were only trying to turn off the sidelight so I would not return to a bike without power.
Seems that some donutbrained idiot locked the steering - in position P. Parking light - on? Check.
