Foam. 10″ rider & 6″ passenger seat width. A LePera design, with a very distinctive styling. The Villain is unlike any other seat currently on the market, certainly not a design for the faint of heart. Features a comfortable passenger area and a high arching rider seat area, that does a great job in battling lower back fatigue. Good for an extra mile in comfort for both rider and passenger with LePera’s Marathon foam filling. Note: Seats for 07-09 XL models will also fit 10-up XL models. For best results LePera advises to use the 10-up XL seat for 10-up XL model years.
