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.
