I was up in PA this weekend with my kids for Sesame Place but made a stop over at Brian's Harley Davidson.Correction. According to a video from Matt Laidlaw where he had the chief engineer walkthrough the bike. Seems the add on for the passenger seat is just a snap in pad - about $209 USD and then the rear mounting pegs kit are around 114 USD.
@scottrod the engineer did not the front lower cowl is a nod to the V-Rod.
