My Brother has that seat on his FJR1300, and swears by it. I did just ride his bike last weekend for about 90 mins straight (no stops) and wow.. no butt pain at all!
I emailed them about a Seat for my 08 Busa, they said they have done them, but they dont have any pics of them.
FYI
His two sons have left that company and have each started their own custom seat making companies (can remember the names right now)
I am seriously considering getting one.
