Aftermarket two-up seats the supplier lists against the Fat Boy 114. Genuine Harley-Davidson is listed above, not here.

Choose the riding position and the passenger space

Start with what you want to change: reach to the controls, room to move or support for longer rides together. A complete two-up seat replaces the seating unit; a comfort pad sits on the seat you already have. Check both rider and passenger requirements before choosing the finish.

Seats with the same family name can have different bases, widths and mounting requirements across years. Select your motorcycle year above; the name alone does not establish fitment.

Choose a complete seat for the correct motorcycle

Hammock 52000746/52000747 uses an internal fabric suspension beneath the foam and can accept its specified optional rider backrest. Sundowner 52000748/52000749 uses a deep-bucket shape and generous padding; each reference has its own motorcycle application and passenger width. Switchback 3 52000803 is the complete tuck-and-roll two-up seat for the specified 2026-on FLTRT Trike, not another Softail seat option. These named seats are not described as heated. Keep the seat and any separately purchased backrest distinct when planning the change.

A pad keeps the existing seat

Circulator 51076-10 is a large 16-inch-wide seat pad, not a replacement two-up seat. Its three-dimensional breathable construction is intended to encourage airflow where the rider touches the seat. An elastic under-seat strap and non-slip base secure the pad. A passenger pillion pad is a separate item; the listing describes how that optional pad joins the rider pad with hook-and-loop tabs. Choose this type of accessory when you want to retain the existing seating unit.

About these products

The Hammock seat and its separate adjustable backrest

The Harley Hammock seat combines a broad seating surface and shallow bucket with a fabric suspension sling beneath the rider. H-D explains that the shape distributes weight and reduces pressure points. Beneath two inches of dual-density foam, the integrated sling supports the rider like a hammock; the manufacturer describes two inches of suspension above the seat pan to prevent bottoming out. These are two different construction measurements, not a claim of four inches of seat thickness or suspension travel.

Black vinyl makes the surface straightforward to clean and maintain, with contrast stitching and an embroidered Harley-Davidson logo. Sealing at critical seams helps prevent rain or wash water reaching the foam in those areas. That is targeted water protection, not a statement that the whole seat is waterproof or that every rider will experience the same comfort.

The adjustable rider backrest 52300745 is sold separately. Its contoured pad supports the lower back without pushing the rider forward, according to H-D, and the slim shape leaves room for the passenger. It matches the seat’s black finish and contrast stitching and slips into the receiver built into compatible Hammock seats. Thumbwheels provide fine height and angle adjustment. The backrest product includes the backrest assembly and protective grab-strap pad; it is not included with the seat and does not fit the original-equipment seat.

The two seat versions are chosen by fitment, not as freely interchangeable sizes. 52000746 has a 16-inch rider width and 11.25-inch pillion; 52000747 has a 16.5-inch rider width and 10.75-inch pillion and is the version listed for the relevant Breakout models. The 52000746 listing also requires removal of the original seat rail on applicable FLI models. On a backrest category, the matching product below is the separate backrest, not a complete seat package. Confirm the exact seat reference, bike year and receiver before combining them.
