Extreme Fastback for Harley-Davidson Fat Boy 2018- 2023


The new Extreme Fastback makes a bold, no-nonsense statement, just like your Fat Boy.  A low-cut 11.5” driver bucket is paired with a tall tail section for incredible back support, while giving a mean racing-cowl look, uniquely styled for the lines of the Fat Boy.  The hand-sewn cover features a double-diamond pattern in front with a perforated-look vinyl on the 7” wide rear.  Go bold and ride free in the comfort of the new Extreme Fastback.

  • 11.5” wide bucketed rider area provides excellent support in a low-profile, sporty package, with a 7” wide rear section.
  • Handsewn cover with double-diamond and perforated accents made from marine-grade expanded vinyl
  • Mustang’s proprietary controlled-density foam formula requires no break-in and retains shape and support after years of use
  • Marine-grade fiberglass baseplate for long-lasting support and durability, with polyurethane bumpers to absorb vibration
