Reading this thread (sorry about your bike), something just occurred to me. When I bought my motorcycle, the dealer included free Microdot security dots with the registration. I don't see a price on the website, but I might look into this for my bicycle, and thought I would make others aware of this product.

I'll post back when I find the cost. The nice thing about the microdot system is that you apply some to every part of the bike, which lets them be found. The downside is that if you replace major components, you'd have to get more microdots.
