10.5" wide seating area. The Bare Bones solo seats are designed to look as thin and narrow as possible, even lower than the Silhouette solo. This gives an unbelievably sleek, low profile. Will complement the lines of every bike from stock factory to radical custom. Built with LePera's high-density marathon foam on a black powder coated steel baseplate for lasting excellence. Note: See 975009 for the optional style matching passenger seat.
