have a thread going for that, check it out! =D
I ordered xena xx14 rear disk lock, its in the mail, so I cant attest to it yet, but others like it. You could even geta front and a rear disk lock if you really wanted tog o above an beyond.
If you could, bolt it down, literally, dig a hole, fill it with concrete and stick an eye hook on top, tie your bike down to it with some sort of lock and chain through a frame area.
Lock your steering wheel.
There are locking covers available.
Get a motion light for your patio.
They also have actual security systems for bikes, with gps build in them and everything so you can track your bike if they get stolen. they are pricey though.
I believe hardracing sells a few of em.
my only other suggestion. if you have a little room, get a shed! lock your bike with whatever you want, discc lock at minimum, and put it in a shed, that way its harder to get to, they have to cut more locks, and its out of sight.
