I keep it in an unlocked garage, door open, with a 91 lb. Husky/Shepard on guard. The dog is actually pretty docile but no-one seems to question his authority over the use of the bike. I never lock or remove the keys when I'm home. It has worked like a charm for over 13 years now. It seems the thought of prying fangs out of their ass has kept the bike safe from thieves.
