What is the best way to secure a motor bike?

buy an alarm mobiliser and get a tracker fitted to it that way the moment anyone attempts to start will set off the alarm and they wont be able to start it and also with a tracker fitted the company will call you and ask you if you are using the bike and they can track it to where it is being taken to and often inform the police as well once you confirm with them that you are not using the bike at that moment
