I have for sale a used Ultimate Seats solo seat with studs and with backrest. It is in excellent condition as is the backrest. The seat is the most comfortable seat I have ever had on a Dyna hands down. It has a bit of surface grime and rust on the tang of the backrest but that is not seen when inserted in the seat. Does not affect use or looks at all. Some scuffs on the seat bottom from use as well. Seat comes with mounting hardware attached to the seat. Seat uses OEM seating position.

Below is the description from the Ultimate website which shows the seat and backrest at $525 new. I am looking to get $350 shipped or make me an offer.

Seat fit 2006 and up Wide Glide®, Super Glide®, StreetBob®, FatBob®, Low Rider® and SwitchBack® models.

Our Midrider seat will sit you at the same height and the same distance from the handlebars as the stock seat. Our Dyna Midrider seat is designed so you sit in the seat, not on the seat.
