Where are the other Porsche Bikes?

I estimate Porsche has produced somewhere around 12,000 to 14,000 bikes from 1996 to the present. These bikes are rather rare, yet quite a few were built. Riding the 1998 Bike S this morning to drop off a rented movie, I wondered if I’ll ever see another Porsche Bike in the wild. Not at a Porsche swap meet or with a Porsche Bike friend, but legitimately out and about with someone riding it. I have a feeling I never will. That’s too bad, but at the same time it makes these bikes even more exclusive than Porsche cars.
