Vintage Pista Porn

Can someone tell me how this photo is Porn? The slack-chain kills it. I mean, why bother with brand new wheels, then photograph it like that?

with_lugs, do you believe that all antique track and path-racer bikes are porn, no matter what the condition, set-up, or the quality of the image? Weird.

It's rarity is of interest, get people thinking about, just to show it to others who want to see it is worth it.
it is a lesser-known bike and wanted people to see them.
