My '07 FZ6 was stolen twice before I got. It was recovered both times but had been ridden a few hundred miles. I often wonder what adventures it was involved in.
I literally leave mine in my parking garage with just the normal key lock. Mine looks rather crappy if you look at it closely lol. I live in s condo I leave the saddle bags on and everything never have any issues. Some one left a bike out on the side street for 6 days and no one touched it lol
