Kryptonite New York Fahgettaboudit Chain with Disc Lock - 3 Ft. 3 In http://amzn.to/VGga23
I read an article by a "x-professional" motorcycle thief who said that the Fahgettaboudit setup is hard to beat. He actually recommend using three locks: the steering lock, a rotor lock PLUS the Fahgettaboudit lock with chain. AND a locking cover. This is the method I use if I park on the street in front of my apartment overnight. I also use the three lock method when my bike is in the storage unit. In a pinch he recommended taking the clutch lever off the bike. That's only a one time deal because if a thief is casing you he'll come back with a clutch lever. (personally I'd like to kick his ass even if he is an "x")
Hope this helps you keep your bike.
