its never about the bikes, it's about the owners. If you're worried sick of someone trying to steal stuff or your machine itself then my suggestion is, why not just sleep with your bike. if not, then dun go around whining like a lil boy if your machine or accesories decides to perform a david blaine on ya.
The bottomline is, **** happens, deal with it. here's my 0.000003 cents, you can keep the change.
