Gripp seating. Rider seat area 12.25" wide; passenger seat area 7.75" wide. Pleated stitch upholstery. Built with LePera’s Marathon Foam on a steel base plate for maximum stability and comfort. The whipped tail improves passenger lower back support. That; combined with the unrivaled high arching back support for the rider makes this a serious in contender when it comes to a mix of style and comfort. Note: This seat comes with Gripp Seating. A ''Gripp Tape'' style upholstery used to help prevent you from sliding on the seat when torque and horsepower kick in. It provides additional grip but still allows you to reposition yourself on long trips.
