How do you turn  the security system off so it can travel on a truck ?

Easy way ,, cable tie the fob to the bike !!!!

Yep thats what I did moving from Perth to Nowra its easier than all that enter fob security code ,2 pushes on the right blinker 2 pushes on the left crap ,sumfin like that I dunno

You "have to know the number(s)"

Well different bike to bike

I hear kiwidave , but the process is in every 2007 and up owners manual

Pain in the arse , and most folks ( and shops !!) just ziptie the fob to the bike

its putting the bike in what is called "transport" mode
the manual tells you how but theres a lad on you tube that gives a straight forward easy demonstration on how to do this
