There are only 2 markets for mirrors, looks, and better than stock visibility. You'll obviously not be able to see behind you as well as you can with the stock mirrors. Myself and many others have GSXR mirrors for the added visibility, and the reasonable $50 price.
It seems your mirrors can only be marketed for looks, as they offer a decrease in function.
They're not bad looking, maybe a chrome option would help sales along too.
A high price always seems to do well with the show crowd anyway, seems the more you pay, somehow the better it supposedly is.
I know that there's alot of overhead launching any part, but at $200 to $300 a set I think the majority of buyers would want improvements other than just looks.
