Mustang 76303 Skyline Signature Series Solo Seat For Harley Sportster (2004-)

Seat Fitment

Seat Installation
Most Mustang seats are designed to install just like your stock seat–using the same mounting points and hardware as your original seat. It usually takes about fifteen minutes to remove the stock seat and install your new Mustang seat. Detailed Mounting Suggestions are included with each seat and can also be found on this site.

Measuring the Width of a Seat
The width of Mustang seats is obtained by measuring across the widest point of the seating area whether for the driver (front width) or the passenger (rear width).

Compatibility with Stock
Since Mustang seat components are built for precision fitment to each other, it is usually not possible to mix and match Mustang solos and rear seats to stock or other aftermarket solos and rear seats. Before purchasing, please inquire regarding each individual Mustang solo or rear seat’s fitment compatibility with stock.

Seat Construction

Mustang seats are meticulously designed so that the baseplate, foam and cover components combine to make the finest, most comfortable seat possible. All seat components are hand assembled at our New England facility to give you the high quality seat that makes Mustang America’s choice for comfort.

Baseplates
Mustang seats are constructed on either a single baseplate (both the driver’s seat and the passenger’s seat are built on the same, single baseplate) or a two-piece baseplate (the driver’s seat is constructed on a separate baseplate from the passenger’s seat).

Both of the pieces on a two-piece baseplate can be attached together for two-up riding or separated to ride as a solo seat. Some Mustang seats feature a two-piece look but are actually built on a single baseplate. Mustang baseplates are constructed of either marine-grade fiberglass or steel.

• Mustang Baseplates for Honda, Kawasaki, Yamaha, Suzuki and Victory Seats
  All baseplates for these seats are made of marine-grade, 3/16″ thick fiberglass, finished in high gloss gel coat. All brackets are riveted in place. Exposed brackets are bright chrome plated. Polyurethane rubber bumpers are strategically located and riveted to the baseplate to prevent it from touching the frame and fender and to minimize vibration. Bumpers will not crack with age and are ozone protected. The hidden brackets have a tough, black epoxy powder coat finish and the edges of all baseplates have a steel reinforced, impact absorbing vinyl edge trim to protect the seat cover Mustang’s unique internal support wings are added to the baseplate to provide maximum driver and passenger comfort. These wings support the entire width of the molded foam. This feature is found on most Mustang touring seats.
• Baseplates for Mustang Seats for Harley-Davidson®
  Formed 16 gauge steel baseplates are black epoxy powder coated on both sides for complete rust proofing. Carpet protects fender paint. Exposed brackets are bright chrome plated.NOTE: FLHT/FLHR Ultra and 2006-up Dyna baseplates are made of marine-grade fiberglass 3/16″ thick finished in high gloss gel coat. This allows for the use of a fender mounted driver backrest kit.

The edges of all baseplates have a steel reinforced, impact absorbing vinyl edge trim to protect the seat cover. Polyurethane bumpers are strategically located and riveted to the baseplate to prevent it from touching the frame and fender and to minimize vibration. Mustang’s unique internal support wings are added to the baseplate to provide maximum driver and passenger comfort. These wings support the entire width of the molded foam. This feature is found on most Mustang touring seats. Bumpers will not crack with age and are ozone protected. Solos with built-in driver backrests have the receiver welded and reinforced to the baseplate for strength. Foam surrounds the hardware to provide maximum comfort.

Foam
All foam is compounded and molded at our New England facility. For a seat to be comfortable, “it’s what’s inside that counts”. The most important component of comfort is the seat foam–both the quality of the foam itself and its design. Each Mustang foam is formulated and cast to be soft enough for comfort and resilient enough to stand up to those “thousand- mile” days. Mustang has over 25 years of experience in compounding the right chemical mix to create the best controlled density polyurethane foam for all-day comfort. The foam has a density of approximately four pounds per cubic foot, depending on the size and thickness of the seat. The foam must then be molded to the correct shape to support your body at the best angle.

Mustang’s high quality foam usually feels firmer than stock but is less firm than other aftermarket seats. It will compress enough to mold itself to your body shape within about 15 minutes of riding time–every time you ride. You do not need a “break-in” period to be comfortable. Your 100th ride will be equal to your 10,000th mile. Mustang seats are known for retaining their shape and support after years of use.

• What is split-foam construction?
  The term simply refers to the look of one style of seats that has the appearance of being made from two parts (a solo seat and a passenger seat) but which is really constructed on a single baseplate. The foam for seats with this look has been split in the middle to give it a two-piece appearance.
• Does Mustang use gel in the seats?
  No, Mustang does not use gel in our motorcycle seats. We manufacture our seats with the very best controlled-density, polyurethane foam possible. To put it simply, gel does not compress it just changes its shape. Foam compresses (what you need your Mustang seat to do) while gel displaces (imagine a tube of toothpaste). Gel may be suitable for a very high-pressure application in a limited area such as bicycle seats or soles of shoes. However, to be fully supported and all-day comfortable, your posterior needs and deserves the cushioning of Mustang foam.
