Well, took the wife for a ride yesterday morning. She's not sure she wants to be a rider. On the stock seat she has to look around me. I'm 5' 10", she is 4' 10". So, I'm thinking about a replacement seat and thinking I should probably get the one with the greatest height for the passenger. That said, in a weak moment last week I ordered an Ultimate replacement seat and should get it in a couple days. Seems like most of the reviews from folks really like it and since they have the 14 day return policy I figured I had nothing to loose (except shipping... which isn't cheap!). Anyway, I guess I'll try it but at the time I ordered it I didn't realize the passenger seat height is probably my biggest concern. So, if anyone has any suggestions it would be appreciated. I can't seem to find this metric on the information about various seats (Ultimate, Mustang, etc.) Thanks!
