11″ wide. Foam, with smooth upholstery. This is a low Bagger seat, low for great looks and for minimum foot to ground distance for a firm stance. Notwithstanding the unmistakable custom look, this is a long distance seat with a full 11″ wide seating area. The included backrest, for that all important lower back support on long hauls, is the accessory that will lift comfort to the next level. Effortless rides, fuel stop after fuel stop… Note: Optional passenger seats are available as 508723 (7.75″ wide) and 508722 (10.75″ wide). These are compatible with the rider backrest.
