Each custom fit seat combines a special insert of SaddleGel™ below a top layer of cushioning foam with a Leather/Vinyl seat cover. The gel is a rubber-like material that stays flexible down to temperatures of -40° F. The gel equalizes body weight pressure as you ride. Gel seats use standard Suzuki seat bases and hardware for a perfect fit. NOTE: Gel in front seat only.For '05-'08 C90/C90T models.
