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.

Why riders pick this

  • High-rising backrest for strong rider support
  • Low-cut 11-inch driver bucket for an aggressive stance
  • Tapered 6-inch passenger section for a streamlined profile
  • One-piece design ensures a clean custom look
  • Positions rider lower and further back than stock

Unleash the aggressive potential of your 1991-2005 Harley-Davidson Dyna with the Mustang Original Fastback one-piece seat. This seat is engineered to position the rider low and back, providing a more engaged and controlled riding experience. The distinctive high-rising backrest offers essential support during hard acceleration, while the tapered passenger section maintains a sleek, custom aesthetic.

Aggressive Styling and Rider Support

  • High-rising backrest provides excellent lumbar support
  • Low-cut 11-inch driver bucket for an aggressive riding position
  • Streamlined 6-inch tapered passenger section
  • One-piece construction for a clean, custom look

Optimized for Dyna Performance

This Fastback seat is more than just a visual upgrade; it's designed to complement the performance-oriented nature of your Dyna. The rider's position is optimized for spirited riding, giving you better leverage and connection to the bike. While the passenger section is tapered for style, it still offers basic two-up comfort for shorter rides. For the ultimate Dyna setup, consider pairing this seat with a performance suspension and exhaust.

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.

Great craftsmanship

Just received my Mustang seat, the quality is indisputable. The seat is very sturdy, every stitch is well place. I do have to confess that I was taken aback by the gap left between the tank and seat (frame exposed). It's comfortable, don't think it's a long ride kind of seat for a passenger but it's a good overall buy.

Great replacement for stock, definitely not a 2up seat.

Looks very good on the bike, flows well the the lines. Improved comfort over stock seat for the driver, very narrow for passenger. The wife yelled 15 min into our first ride with the new seat. If you're looking for a 2up, this is not it.

Quality Mustang Seat!

The original Iron 883 seat was a bit uncomfortable to me after short rides. I purchased the Mustang Tripper Fastback seat after reading a few reviews. I purchased it because I liked the looks as well as the reviews. After putting a few hundred miles on it solo, I must say it was an excellent decision! It moved me back on the bike maybe an inch or so, which fit right with the new forward controls. I can ride for hours on a weekend with no discomfort at all now! The shape of the seat just seems to flow with my 883, and the quality is just as well. I have no plans for any passengers, but i wanted a place to be able to bungee a jacket or such, so the 2 up part of the seat will serve that purpose for me. Overall, I love my new Mustang Fastback Tripper seat!!

Great looking seat!

I purchased this seat so that my girlfriend could ride with me. It looks excellent but isn’t the most comfortable for her. It’s fine for a short ride, though, and looks very sleek and fitting.

Item was delivered promptly. Accurately described. This seat is low profile, sits you lower and further back, firm but not uncomfortable. Good quality. Gap between seat and tank minimal on 4.5 gal Sportster. Exactly what I expected.
