Stupid question but recently picked up a 08 Fat Bob and dont know any thing about if there is a security system. Is there a stock system or if it is optional how do you know if you have one? I didnt get a fob but dont know if the orginial owner just attached it to the bike or if there is not one. There is no way to contact orginial owner. I have a had a lot of bikes but new to harleys.
