Installation Requirements
WARNING
Do not install these seat kits on motorcycles that are not equipped with an appropriate grab strap and passenger footpegs. If footpegs and grab strap are not installed, passenger could fall from moving motorcycle or grab onto operator, causing loss of control and death or serious injury. (00410b)
Models WITHOUT passenger footpegs require their installation. See the P&A retail catalog or the Parts and Accessories section of www.harley-davidson.com (English only) for the correct passenger footpegs and mounts.
FXSTC Softail Custom models with original equipment (OE) upright and king or queen seat require separate purchase of:
  • A Seat Nut Kit (Part No. 59768-97).
  • A seat mounting screw (Part No. 2952A).
  • If desired, a passenger backrest compatible with the OE upright.
WARNING
Rider and passenger safety depend upon the correct installation of this kit. If the procedure is not within your capabilities or you do not have the correct tools, have a Harley-Davidson dealer perform the installation. Improper installation of this kit could result in death or serious injury. (00308b)
NOTE
This instruction sheet refers to service manual information. A service manual for this year/model motorcycle is available from a Harley-Davidson dealer.

IMPORTANT: READ BEFORE RIDING
Pressure Adjustment
  1. Before sitting on the seat, inflate the seat to the point of bulging the seating surface. Inflation takes 30 pumps or more with the bulb pump.
  2. While seated, adjust the air pressure first by deflating with the vent valve until seated pressure feels distributed throughout the seating surface. Experiment to find the most comfortable inflation state.
  3. If too much air pressure is released, inflate the seat again with the bulb pump while either on or off the seat.
  4. Periodically check to see if there is adequate pressure in the seat. Shift your weight, or lean your body (not the motorcycle) from side to side. The air within the seat transfers from cell to cell beneath you to redistribute the pressure.
NOTE
  • Avoid adjusting this seat while in motion. Get as close as possible to ideal seating pressure while stationary to avoid distraction while riding.
  • Proper adjustment can only be made while the rider is seated on the cushion, in normal riding position.
  • For optimum comfort, find the balance between air pressure and foam support from the seat. Adjust the seat according to rider and passenger size, weight, riding position and time in the saddle.
  • Do not over-inflate! This seat works most effectively with a moderate amount of air. Over-inflation results in a floating, unstable feeling, and does not effectively distribute the seated pressure loads.
Care and Maintenance
  • When mounting or dismounting the vehicle, avoid dragging a boot or other potentially damaging object across the seat surface. Boot edges, buckles and conchos can snag and scar the seat material. This damage is NOT a warrantable condition.
  • To clean the seat material, treat as furniture upholstery. Vacuum regularly to remove dust and debris embedded in the fabric. Use water and mild detergent (NOT laundry detergent) to remove minor blemishes. Commercial spot removers can also be used with light wiping or blotting. DO NOT "brush" clean as that can damage or snag the fabric.
  • The seat materials are resistant to contact with all common chemicals used in and around the vehicle. However, flush with water and clean up as soon as chemical contact occurs.
  • Seat fabric surfaces are treated with a water-resistant coating, but use a seat cover when vehicle is stored outdoors.
  • Do not direct any high-pressure water toward seat surfaces. When washing vehicle with a pressure washer, remove the seat or use a seat cover.
Proceed to the INSTALLATION section for the specific model.
INSTALLATION, SPORTSTER MODELS
NOTE
Avoid scratching painted surfaces with tools or metal seat tabs during installation.
Preparation and Removal
1. Remove seat per the service manual. Save the mounting screw for installation of the new seat.
2. See Figure 1. If there is NO seat retention nut at the forward seat-mount location (2), install the seat retention nut from the Seat Nut Kit ( Figure 9 , Item 7).
a. Remove the plastic plug, if present, from the forward hole location in the fender by pushing up from under the fender. Save the plug.
b. See Figure 2. Get the cable strap (3) from the kit as an aid to install the seat retention nut (1) and washer (2). Place the nut over the cable strap so the wide end of the nut rests on the eye of the strap. Thread the cable strap up under the fender and through the fender hole. Pull up on the cable strap to hold the seat retention nut snug against the underside of the fender.
c. Position the seat nut rib in the fender hole notch. Slide the retention washer into the exposed retention nut slot from the rear to lock the nut in place. Remove cable strap.

3. See Figure 1. Chopped-fender Sportster models (like 883L, 883N, 1200N, 1200V 1200X) have a threaded hole at the rear seat mount location (4), and require a nylon step washer ( Figure 9 , Item 10) to protect the fender when the seat is installed. Remove the screw in the rearmost fender hole and discard. Full-fender Sportster models: If the motorcycle is not equipped with a seat retention nut at the rear seat mount hole location (4), one must be installed in order to install the seat.
a. If the retention nut from the Seat Nut Kit ( Figure 9 , Item 7) is available, install that nut. If the retention nut from the Seat Nut Kit was installed earlier, remove the mid-fender location ( Figure 1 , Item 3) retention nut already installed on the vehicle.
b. Remove the plastic plug from the rear hole location in the fender by pushing up from under the fender. Save the plug.
c. See Figure 2. Get the cable strap (3) from the kit as an aid to install the seat retention nut (1) and washer (2). Place the nut over the cable strap so the wide end of the nut rests on the eye of the strap. Thread the cable strap up under the fender and through the fender hole. Pull up on the cable strap to hold the seat retention nut snug against the underside of the fender.
d. Position the seat nut rib in the fender hole notch. Slide the retention washer into the exposed retention nut slot from the rear to lock the nut in place. Remove cable strap.
e. If desired, install the plastic plug removed earlier into the vacant fender hole.
Grab Strap Installation
1. See Figure 9. Get the grab strap (3), hex screw (5) and fender washer (9) from the kit.
2. Determine the correct hole choice for the grab strap from Figure 3 and Table 1. Loop the strap so the seam is on the inside and the chosen holes are aligned.
3. Place the fender washer onto the screw threads. Insert the screw through the aligned grab strap holes from the inside of the loop outward.
4. See Figure 1. At the forward hole location (2), thread the hex screw into the retention nut finger-tight.
5. Pivot the outboard ends of the grab strap around the hex screw so the strap ends cross each other at about 90 degrees with the strap ends facing rearward.
6. Tighten the screw to 6.8–10.2 N·m (60–90 in-lbs).
Seat Installation
1. From the front, insert the rear of the new seat through the grab strap loop until the seat front tongue engages the fuel-tank seat mount.
2. Angle the front of the seat into place so the front tongue engages the slot at the rear of the fuel-tank mounting location.
3. Push the seat forward. Rotate the rear of the seat downward until the seat contacts the frame. Flex the seat slightly in the middle. Slide the seat towards the rear so that the bracket on the underside engages with the center seat post on the frame.
WARNING
After installing seat, pull upward on seat to be sure it is locked in position. While riding, a loose seat can shift causing loss of control, which could result in death or serious injury. (00070b)
4. Pull up on the center of the seat to verify that it is locked into place. There will be a small amount of play, but the seat should be held firmly in place by the post on the underside. If the seat is not firmly in place, repeat previous steps until the seat is locked into place. See the owner's or service manual for further seat placement instruction.
5. Install the seat mounting screw removed earlier. Fasten the seat mounting bracket to the top of the rear fender.
6. Chopped-fender models (like XL883L, 883N, 1200N, 1200V 1200X): Place guide washer over rear seat mounting hole in fender before installing seat screw.
7. ALL Sportster models: Tighten the mounting bracket screw securely to the fender to 6.8–10.2 N·m (60–90 in-lbs).
8. Read and understand the Pressure Adjustment and Care and Maintenance sections on Page 1 before riding with your new seat for the first time.
