Biker Gel. Sorrento stitch style upholstery. 12″ rider seat width, 9″ passenger seat width. A fusion of Silhouette styling and Maverick comfort. The entire seat is shaved down for a flowing profile. Note: Biker Gel has a unique way of forming to the rider/passenger, distributing weight evenly across the seat and removing pressure points. Due to its memory characteristic, Biker Gel never loses its shape. It will not freeze, crack, melt or break down and it will never leak because it is a solid gel, not a fluid. Don’t expect a soft, pillowy feel. Biker Gel provides a firm, firmer than the LePera Marathon foam, supportive foundation that shows its true quality better the longer you ride. 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.
