Well as we have just found out this seat fits 2009/10 to 2013 !
Does not fit an M8 Roadking ( a LOVELY bike by the way !) and we did try.
SO still for sale. Summat stupid like $1000 to buy direct, mental if yer asks me !
$400 would own this seat. That's a very fair price.
I get $400 for Softail seats all the time and this is MUCH rarer
Having done more research this seat will fit 2009 to 2013 inclusive ( Corbin website )
It was on a 2011 103 Ultra Limited , which had been a "brochure photo" bike for Klockwerks the aftermarket screens etc etc mob in the US
Was bought by my mate off the Klockwerks stand at Daytona Bikeweek in March 2011
