Hello,

Just got the Sundowner seat for my 2014 FLHTK.
Have to say it doesn't seem to feel much different from the stock seat on short around town trips - although I haven't tried it out on long trips yet - maybe I will see an improvement then. Will post after I have tried a long trip with an update (next week I am going to Moruya from Canberra so I'll have a chance to try it out then)...
Can't complain too much as it only cost $379 AUD...

 

I have the Sunray -- the heated version of the Sundowner -- and it was a huge improvement over the Road King's standard seat.

But I thought that the Ultra's stock seat is basically the same thing as a Sundowner, at least it sure looks similar. Maybe that's why you're not noticing much change. In any case, it takes a good long ride to really evaluate a seat.

 

Sundowner makes more difference for the passenger than the rider.
