Does your bike have the Factory security system on it? Does it have a siren? If yes, but no, then get yourself the siren module and install that. Plug and play.
That is about the best you can do. Alarms, chains or aircraft cable, etc. only protect the bike from "mostly honest" citizens. Anybody that wants the bike is gonna get it. Four guys and a pickup, and the bike is gone. All that is left is the chain or cable laying on the ground.
So park it in a crowd, where you can see it from the window, lock the fork, set the alarm, if you have a padlock you can put that through the front rotor (but PLEASE don't forget to take it off before you go!!). These things may slow the pros down or make them pick a bike that has no security at all.
