Comfort and ergonomics:
The seat is real comfortable, both for me and my wife as a passenger. The ergonomics felt great on the test ride but on a longer ride my back starts to bother me. The riding position is similar to my Super 8 but I think my feet are a little further forward and the seat isn't sloped forward like my Super 8. i think that these two thing are what is causing my back pain. If I don't get used to it I may try modifying the seat.
There isn't much wind protection so I'll probably add a small windscreen. Piug make a couple that look great.
My wife and I spent a weekend riding in the North Carolina Mountains. We had a blast. She was very comfortable on the back until the very end of the second day when her tailbone started to hurt. The passenger pegs are pretty far forward putting more weight on her tailbone.
Here's a pic of us two up:
I've got a lot more pics and a full ride report of that trip here:
