LoJack works, but it's expensive. I'd go with full coverage and maybe a disc lock or a Kryptonite New York chain. The latter comes with a disc lock and can easily deter any wanna-be thief because it's nearly impossible to break in a short period of time (that's what I used to protect my SV650 in college). I'd agree with Tonik, you'd benefit more from full coverage and probably get more money back in a claim if anything did happen to it. I have the same problem at our apartment where we have no covered parking or garages (we're on the Columbus side of the Westerville line). We have full coverage insurance on our bikes and really don't do anything else for them, maybe a cover every now and then for the rain/snow. Aside from the insurance, we're not too concerned about theft. My FJR is very well-known and very undesired, and nobody knows what a Z1000 is (at least at Q-S-L bike nights).
