Here's some pics. I'm not sure what the part number is. They were on my bike when I bought it in Oct 2007 and the stockers came with it. I'm pretty sure Yamaha called it the "Comfort Gel Seat" at the time, but I wouldn't swear to it. Shortly after getting the bike I had a Mayer saddle made on the stockers pans and these have been in the cabinet every since.
