I have one on my '09 Ultra. It is comfortable for the long haul. BUT, the passenger seat is tilted towards the front so my passengers have to reposition themselves several times an hour to the back of the seat. Also my right thigh felt a pressure point on the back that caused my leg to feel like it was going numb (but that could be a result of half cooking my leg riding slow in 100+ F through construction areas in B.C's Okanogan area).
I put the stock seat back on last fall and for my weight it's not bad for shorter 5 hour rides.
