I have one for a wide tire bike that needs a good home. PM me if your interested.

 

Since the stock seat is so comfortable, I had though about changing the sissy bar to the taller twisted version and then getting the seat reworked to incorporate a metal plate in the back where they could make the backrest taller. I don't know if they could do that or not but the king and queen seat gives the bike that chopper style that I like. Throw on some Kuryakyn passenger peg relocation brackets and she should be comfortable.
