The seat I chose is a Saddlemen Explorer. Comfort is provided by a combination of progressive density foam and SaddleGel. The rider's portion has an eight-inch tall lumbar support, creating a bucket seat, with the lumbar section having separate padding "so they compress independently, reducing tailbone and hipbone pressure." While the seat is an improvement over stock, it's harder and puts the rider closer to the tank, leaving no room to move fore and aft. Also, the front portion of the saddle pushes up uncomfortably, like many saddles on road bicycles. Conversely, the passenger portion is a vast improvement over stock, measuring 13 inches across and 14 inches from front to rear. Lastly, there was an odd gap between the passenger seat and fender, big enough for daylight to shine through.
