Not a stupid topic. Your Honda is heavy enough to require a pair of skateboards and some grunting to scoot it to a waiting vehicle, but the Kawasaki can be moved by four guys with two pipes through the wheels.
If you leave it in a parking garage, can you park in a well lit area near a surveillance camera? On the street, can you park in a similar area? Good lighting and the possibility of being recorded will deter some of the thieves.
I have a Abus disc lock with an audible alarm to draw attention to someone moving the bike. Mine only weighs 300 lbs, so it'd be an easy target. If you'll be fairly close to the bike, you may find an alarm system that uses wifi to alert you by phone, but without paying for a dedicated cell connection. If you're will to spend the money, there are systems that use a cell connection to alert you by phone and allow tracking.
