About Mustang Motorcycle
Mustang Motorcycle Products has built seats in Terryville, Connecticut since 1980, and is the name most V-twin riders reach for when the stock seat has ended a ride early. Its wide touring and solo seats are built on steel baseplates with real foam density rather than cosmetic padding.
The Mustang Original Fastback one-piece seat transforms the look and feel of your 1991-2005 Harley-Davidson Dyna. Designed for riders who prefer an aggressive, low-slung stance, this seat features a high-rising backrest for support and a streamlined passenger section. It's built for performance and style, enhancing your Dyna's lines.

Common questions
Will this seat fit my 2006 or newer Harley-Davidson Dyna model?
No, this Mustang Fastback seat is specifically for 1991-2005 Harley-Davidson Dyna models. 2006 and newer Dyna frames require a different seat.
How does the driver's position compare to the stock seat?
The 11-inch driver bucket is cut low and set back, providing a more aggressive, planted riding position compared to the factory seat.
Is this seat comfortable for two-up riding on long trips?
The driver position is optimized for solo performance and an aggressive look. The 6-inch tapered passenger section offers basic two-up comfort, but it is narrower and more streamlined than a dedicated touring passenger seat.
