I recently purchased a Corbin seat and backrest designed to the 2011 Stryker. I am very impressed with it. It was priced comparable to the Mustang but had a lot of choices of leather and colors. The also do custom stitching. One note though. The Corbin site says the seat is compatible with the OEM quick release back rest system. This is true but only for the TALL quick release system. It does not work with the Short system.
