My husband has a Duece and my experience as a passenger is that the seat is not very comfortable. We rode 60 miles Saturday and I couldn't wait to get off. The seat is very hard and I've actually ended up bruised after a long ride. I haven't ridden on a Dyna but when sitting on them on the floor I thought that the DWG seemed more comfortable. Of course you can always get a different seat but that's not cheap.
