you could safety wire it, and if its been tampered you should be able to tell.
i know this isnt really theft preventive, but in the end nothing really is.
for when its under the carport at night instead of the garage or if i leave town a couple days or have to stay at a hotel.
If you have a Garage why not put the bike in it everynight ( Mine is ) Solves that problem, As for a hotel, Get a ground floor room and pull it inside.
