lock

Hello everyone, I read quite a few posts already, as well as talked with Sicass, but still haven't found the answer I am looking for. This is why I registered here before I make an order for a keyed ignition, because I want to be as sure as I can be, that the part will actually fit and work...

How many of you guys lock your steering when you park? I bought my bike used and never got a steering key lock with it. Would it have to be custom made?
