Maybe I'm just dim or clueless, but I didn't know there was a new pillion seat offered for the C5 until I saw it on the UK distributor's site and called CMW to see if these seats were stateside yet. They have them, color-matched, but it is one of those things you have to order through your dealer, as I assume many of the UCE accessories are going to be. It has a color-matched subframe that attaches to the shock mounts in the rear and to the unused bracket under the seat with the long bolt shown. As indicated in the photo, it also comes with a shorter bolt whose purpose is totally lost on me (If anyone knows, please let me know, right now I am using it to clean out earwax). I don't yet have a photo of the bike with the pillion installed, but I think it looks great, proper "period" design, and it mates closely enough to the stock rider's seat that it gives me just an extra skoosh of slide-back room for my tall, fat and generally repulsive self. I've posted a photo here in the Gallery under "modifications" and it would be dated today, 2/24.
