I have to take umbrance with the writer as he needs to do a little more research.
Assuming the bikes in the story are all window dressing is not something I've seen as the case. I plan on riding mine as much as schedule and weather permits (and the extracurricular activities of 5 kids...but thats another story).
I certainly do not see any evidence on this board that the majority of us are collectors of performance bikes....more likely collectors of experiences and adrenaline rushes. Sightings may be rare in some cases but doddling around on them only for show is probably more rare.
