Mustang's advanced comfort technology lets you ride low, look cool and still be comfortable at the end of a day's ride. Places the driver slightly lower and further back compared to stock for more room in the saddle, with an 8" wide passenger area that offers comfortable 2-up riding. Note: All passenger seats and one-piece seats in this section require the stock rear mounting bracket be removed from the stock seat and bolted to the Mustang seat. If the stock bracket is missing, use Mustang bracket #78037 or H-D® #52467-00.
