I bought a Mustang Sport Touring seat (Part number 75486) for my 2005 Road King Custom. I only put about 100 miles on it. I love the look of the seat, however I am short (5'5") and it moved me up and that does not work for me. My lose and your gain. These sell for $450 new, will sell for $275 + Shipping.
Fits 1997-2007 Road Kings and Street Glides
