I have a Sundowner seat and I can tell anyone interested, particularly those with a flat ass, this seat is a must have.. seriously.
I rode my bike from south TX to Key West last year.. squirming around after 40 miles after every stop. by time I got to HD in Daytona I had the Sundowner on my bike.. My sore ass/tailbone issue has disappeared.. rode back from Key West and made a trip to Vegas and back, no issues..
When I traded in my 2011 Ultra Limited for this 2016 RGU I made a deal with HD dealer that my seat comes with me, but in all fairness I'll give this stock seat a spin because it does "LOOK" more comfortable than the stock seat on the Limited... Nope!! Was back in two days to swap it out for my Sundowner.. I will never let her go ever again..
