Ride sun-up to sun-down in comfort and style. The Sundowner Solo Seat's shape and foam density were developed and refined during hundreds of hours of test rides and ergonomic evaluations. The unique seat features a deep bucket design that cradles the tailbone and provides back support for the rider. The narrow nose of the seat was sculpted to bring the legs closer together, and to look great with any size Sportster fuel tank. The seat is constructed with premium textured vinyl surfaces for comfort and durability, and features embroidered Bar & Shield® logos for style. For two-up riding, simply add the comfortable Sundowner Passenger Pillion P/N 52400121.
