There was a sneek peak of the Seat Concepts seat in the previous post. Here are a few more. Measured the height - 35 1/2" at the nice cushy wide part of the seat. Drops down a 1/2" in the pocket. Wife not a fan of the passenger accommodations. I"ll just switch to the two piece when she comes along. I need to move my tail bag back a little because this seat is a little longer than the stock one. Very snug squeezing it into place. With the stock one the tail goes in first then drops and locks into place. At first I had trouble getting the seat to latch. On the rear seat support they had these two nubbins that prevented it from seating fully. I guess you might be able to smack it down on to the bikes rubber supports. I just trimmed the nubbins off. Bag mount: I used the rear rack mount threaded holes along with some spacers to keep the passenger horns tight. The two screws on the rear just hold the bag to the base material so it doesn't droop back there.
