78808 Double Diamond Squareback.

The Mustang Double Diamond Squareback seat is engineered for riders who want performance-inspired styling without sacrificing long-haul comfort. It features an 11.5-inch wide driver bucket that is cut low to the frame, paired with a high-rising rear wall that provides essential lower back support during aggressive riding. For two-up trips, the squared-off 7-inch wide passenger section offers plenty of utility without compromising the bike's stance. This seat fits 2018 to 2025 Low Rider S and Low Rider El Diablo models, as well as 2018 to 2021 Sport Glides. It is a fantastic upgrade for those looking to lock themselves into the bike while maintaining a clean, custom look for their Softail.
