The Harley-Davidson Adjustable Rider Backrest is a premium accessory designed to enhance rider comfort and support during long rides. This article provides a comprehensive, step-by-step breakdown of the installation process, along with detailed technical specifications, compatibility information, and usage instructions. The content is derived exclusively from the official product pages and technical documentation provided by Harley-Davidson, ensuring accuracy and reliability for U.S. consumers, motorcycle enthusiasts, and DIY users.
Overview of the Adjustable Rider Backrest System
The Adjustable Rider Backrest is a modular system consisting of two primary components: the backrest pad and the mounting bracket. Together, these components allow riders to customize their seating experience by adjusting the backrest forward, rearward, and vertically. This flexibility is particularly beneficial for riders with varying body types or those who frequently ride long distances.
The backrest pad is constructed from smooth vinyl and features a sleek design that provides full lower back support without pushing the rider forward. It includes a pull knob for height adjustment and an integrated gas spring that enables one-handed adjustments. The mounting kit includes a bracket, handle, and all necessary hardware for installation.
According to the documentation, the backrest is compatible with select 1997-and-later Touring models, as well as certain Trike models equipped with one-piece slotted seats. However, it is not recommended for all Original Equipment (OE), CVO™, or low-profile styled accessory seats due to potential aesthetic incompatibility.
Compatibility and Vehicle Requirements
To ensure proper installation and functionality, it is essential to confirm that the rider’s motorcycle meets the necessary specifications. The Adjustable Rider Backrest is designed to fit the following models:
- 1997–2020 Touring models (excluding 2021-and-later FLH, 2023-and-later FLHFB, and 2025-and-later FLTRXRRSE models)
- Trike models equipped with one-piece slotted seats
It is important to note that the backrest is not compatible with all motorcycle configurations. For example, some low-profile or CVO™ seats may not accommodate the backrest without altering the vehicle’s appearance. Additionally, Trike models require a different mounting configuration than standard Touring models.
The mounting kit is sold separately and is model-specific, meaning users must purchase the correct version that matches their motorcycle’s make and model. The mounting kit includes a bracket, handle, and installation hardware but does not include the backrest pad.
Installation Process
The installation of the Adjustable Rider Backrest is a multi-step process that requires attention to detail and adherence to the manufacturer’s guidelines. Below is a detailed breakdown of the installation steps, derived from the official technical documentation.
Step 1: Prepare the Motorcycle
Before beginning the installation, ensure that the motorcycle is stable and the rider has access to the necessary tools. The following tools are typically required:
- Socket wrench set
- Pliers
- Adhesive (as specified in step 4)
- Masking tape
- Clean, flat surface for seat placement
The installation should be performed in a clean, well-lit environment to prevent damage to the seat or backrest components.
Step 2: Install the Mounting Bracket
The mounting bracket is the foundational component of the backrest system. It must be securely attached to the motorcycle’s frame to ensure stability and proper function.
- Begin by installing the mounting bracket and handle according to the manufacturer’s instructions. The bracket should be aligned with the existing seat mounting points.
- Secure the bracket using the provided hardware. It is crucial to ensure that the bracket is level and properly aligned before tightening the bolts.
- Test the movement of the handle to verify that it operates smoothly and without resistance.
Step 3: Install the Backrest Mechanism
After the mounting bracket is in place, the backrest mechanism can be installed.
- Align the backrest mechanism with the mounting bracket. The backrest should slide into place with minimal resistance.
- Press gently on the backrest until it snaps into position. A locking mechanism ensures that the backrest remains secure during normal operation.
- Test the backrest’s movement by pushing the handle forward and rearward. The backrest should adjust smoothly across its 30-degree range of motion.
Step 4: Install the Seat Protector
The seat protector is an essential component that prevents wear and tear on the motorcycle’s seat. It also ensures that the backrest functions properly without damaging the seat material.
- Obtain the seat protector and apply masking tape to the non-adhesive side to assist with positioning.
- Insert the seat protector between the seat opening and the backrest mechanism, ensuring that it extends to the edge of the seat.
- Carefully adjust the protector so that the upper edge is positioned approximately 1/2 inch (13 mm) above the rear edge of the mechanism.
- Temporarily adhere the masking tape to the seat to hold the protector in place during the installation process.
Once the protector is in position, it can be removed and reinstalled after the backrest is fully installed.
Step 5: Final Adjustments and Testing
After the backrest and seat protector are in place, the final adjustments should be made to ensure optimal functionality.
- Push the backrest to its fully forward position and verify that it locks securely.
- Adjust the height of the backrest using the pull knob on the rear of the pad. This knob allows for a 1.5-inch height adjustment across five positions.
- Test the backrest by leaning forward and backward to ensure that it moves freely and locks into place without resistance.
- Once satisfied with the adjustments, remove the masking tape from the seat protector and secure it in place with adhesive. Allow 24 hours for the adhesive to cure before exposing the seat to moisture or extreme temperatures.
Adjusting the Backrest for Optimal Comfort
The Adjustable Rider Backrest is designed to be user-friendly, allowing riders to make quick adjustments without dismounting the motorcycle. Below is a detailed explanation of the adjustment process:
Forward and Rearward Adjustment
- To adjust the backrest forward or rearward, locate the adjustment handle on the backrest mechanism.
- Push the handle toward the desired direction (forward or rearward). Leaning back against the backrest pad helps adjust it rearward, while keeping weight off the pad causes it to move forward.
- Release the handle once the backrest is in the desired position. The handle will lock the backrest into place.
Vertical Adjustment
- To adjust the height of the backrest, locate the pull knob on the rear of the pad.
- Pull the knob to unlock the vertical adjustment.
- Move the backrest up or down into the desired position, then release the knob to lock it in place.
Folding and Removing the Backrest
For situations where passenger mounting is required or when the backrest needs to be removed, the system allows for easy folding and removal.
- To fold the backrest down, pull the handle and gently lower the pad. The backrest will fold into a compact position that allows for easier access to the passenger seat.
- To remove the backrest entirely, follow the steps outlined in the installation instructions, reversing the process.
Maintenance and Warranty
The Adjustable Rider Backrest is covered under a 1-year limited warranty, as specified in the manufacturer’s documentation. This warranty covers defects in materials and workmanship but does not include damage caused by improper installation, misuse, or normal wear and tear.
To maintain the backrest in optimal condition, it is recommended to:
- Clean the backrest pad regularly with a mild soap and water solution
- Avoid exposure to extreme temperatures for extended periods
- Inspect the mounting hardware periodically for signs of wear or loosening
