Harley-Davidson offers a range of rider comfort solutions, including the Adjustable Rider Backrest and its associated mounting kit. Designed specifically for select Touring models, these components provide enhanced ergonomics and adjustability for riders. This guide provides a detailed, step-by-step overview of the installation process based on official installation instructions, hardware specifications, and model compatibility details from Harley-Davidson’s service documentation and product information.
Overview of Components and Compatibility
The Adjustable Rider Backrest and its mounting kit are designed for use with specific Harley-Davidson Touring models. According to the provided documentation, the kit is compatible with '09-later Touring models that feature a one-piece slotted seat. Notably, it is not compatible with '21-later FLH, '23-later FLHFB, or '25-later FLTRXRRSE models. It also does not fit Trike models.
The installation process requires the use of several components included in the kit, such as a mounting bracket, actuation handle, and various fasteners. The backrest pad itself is sold separately and must be purchased independently. The mounting kit includes all necessary installation hardware and is described as a necessary addition when installing an adjustable rider backrest.
Installation Tools and Skill Requirements
The installation process is categorized as requiring a certain level of technical skill. According to the documentation, it is recommended that users have at least a basic to intermediate level of mechanical proficiency. The suggested tools for installation include:
- Safety glasses
- Torque wrench
These tools are essential to ensure the correct tightening of fasteners to the specified torque values. For example, some screws in the kit must be tightened to 5.1–6.2 N·m (45–55 in-lbs), while others require 8–11 N·m (6–8 ft-lbs). Proper use of a torque wrench is crucial to avoid over-tightening or under-tightening, which could lead to mechanical failure or improper function.
Step-by-Step Installation Instructions
The installation process is divided into several key steps, each of which is outlined in the documentation. These steps include mounting the bracket, routing cables, and securing the actuation handle and backrest pad.
1. Mounting the Backrest Bracket
The installation begins with the mounting of the backrest bracket. This step is critical for ensuring the stability and proper function of the backrest system. According to the instructions:
- Install the actuator handle with cable to the actuator handle bracket so that the cable is pointing downward when installed.
- Secure the actuator handle with screws and nuts.
- For models without a mid-frame air deflector, slide the flat side of the actuator assembly behind the spark plug wires.
- Verify that the hook or bent tab on the bracket engages with the cross-member plate.
- Secure the assembly with a screw and washer, tightening to the specified torque of 5.1–6.2 N·m (45–55 in-lbs).
For models equipped with a mid-frame air deflector, an alternate installation option is provided. In this case, the actuator assembly must be installed in a slightly different manner to accommodate the presence of the air deflector.
2. Cable Routing
Proper cable routing is essential for the smooth operation of the backrest mechanism. The documentation outlines the following steps:
- Clean the area on the adjustment handle bracket where the spark plug wire clip was removed using a solution of 50% alcohol and 50% water.
- Install the wire guide onto the bracket.
- Route the spark plug wire through the clip and fold the clip to secure the wire.
- Route the cable under the cross-member.
- Continue routing the cable between the fuse/electrical box and the frame to the top of the rear fender and to the backrest bracket.
It is important to ensure that the cable is routed correctly to avoid interference with other components and to prevent damage to the wiring.
3. Attaching the Release Cable
The release cable is responsible for allowing the rider to adjust the position of the backrest. The installation of this cable requires careful attention to detail:
- Attach the release cable to the backrest mounting bracket as shown in the provided figure.
- Secure the cable to the shaft of the gas spring using the provided cable strap.
- Do not over-tighten the cable strap to avoid damaging the components or affecting the functionality of the backrest.
Once the cable is attached, the rider can use the actuation handle to adjust the backrest forward or rearward, as well as up and down.
4. Adjusting the Backrest Pad
After installation, the backrest pad can be adjusted to suit the rider’s preferred position. The following steps are outlined in the documentation:
- Leaning back against the backrest pad helps adjust it rearward.
- Keeping the rider’s weight off the backrest pad while pushing the handle causes the backrest to move to its full forward position.
- Releasing the handle locks the backrest into place.
- To adjust the backrest pad up and down, pull the knob on the rear of the pad. Care should be taken to avoid pushing the seat forward too far, as this could damage the seat material.
- The backrest pad can also be pushed forward against the seat to facilitate getting on and off the motorcycle without activating the release handle.
Hardware Specifications and Included Components
The mounting kit includes a variety of hardware components, each of which plays a specific role in the installation and functionality of the adjustable rider backrest system. The components are listed as follows:
- Mounting bracket
- Washer (3 pieces)
- Screws (3 pieces, 8–11 N·m torque)
- Locking flange nut (3 pieces)
- Actuation handle kit (includes items 6 through 13)
- Screws (1 piece, 5.1–6.2 N·m torque)
- Clip nut
- Wire guide
- Screws (2 pieces)
- Washer (1 piece)
- Lock nut (2 pieces)
- Actuator bracket handle
- Actuator handle with cable
- Cable strap
- Backrest mounting base
- Seat protector
- Gas spring kit
It is important to note that the backrest pad itself is sold separately and is not included in the mounting kit. Additionally, the pivot bracket repair kit is listed as an optional component for certain repairs.
Safety and Warranty Information
The installation process involves the use of mechanical components that must be handled with care to avoid injury or damage to the motorcycle. The use of safety glasses is strongly recommended, particularly when handling sharp or small parts. Additionally, all installation should be performed in a clean, well-lit area to reduce the risk of contamination or misplacement of components.
The Adjustable Rider Backrest and mounting kit are covered under a 1-year limited warranty. Users are directed to the Harley-Davidson website for full warranty details.
Conclusion
The installation of an Adjustable Rider Backrest on a Harley-Davidson Touring model involves a series of precise steps that require attention to detail and mechanical proficiency. The mounting kit provides all necessary hardware for the installation, but the backrest pad must be purchased separately. The process includes mounting the bracket, routing cables, and securing the actuation handle and backrest pad. Proper use of tools such as a torque wrench is essential to ensure that all components are tightened to the specified torque values.
Users should follow the provided installation instructions carefully to avoid damage to the motorcycle or the backrest system. The process is designed to be manageable for those with intermediate mechanical skills, though caution and precision are required throughout. After installation, the rider can adjust the backrest to their preferred position using the provided handle.
