Harley-Davidson® Genuine Motor Parts & Accessories offers a host of new accessories for 2021, each designed for a personalized  Harley-Davidson riding experience. Every Harley-Davidson Genuine Motor Accessory is factory-engineering and tested to meet the highest standards in the industry for fit, durability, and performance. New-product highlights for 2021 include:

Harley-Davidson® Audio powered by Rockford Fosgate®

Harley-Davidson and Rockford Fosgate have worked together to create the new level of motorcycle audio performance and customization. The all-new components comprise- an advanced, high-performance audio system that pushes the bounds of technology, featuring speakers and amplifiers designed specifically for Harley-Davidson® motorcycles. Harley-Davidson® Audio powered by Rockford Fosgate® is featured on the 2021 CVO™ Street Glide® and CVO™ Road Glide® models, and an accessory for 2014-later Harley-Davidson® Touring motorcycles equipped with a Boom! Box infotainment unit.

Key features of Harley-Davidson® Audio powered by Rockford Fosgate® include:

  • R-Tune: Equalization is specific to the motorcycle environment, designed to be stronger and louder, to overcome road rumble and wind noise. Left and right speakers are designed to project sound directly at the rider for an enhanced audio experience.
  • M-DEQ™ (Motorcycle Dynamic EQ): The smart amplifier adaptively changes the EQ points in real time, meaning the tune changes to ensure incredible sound quality no matter the motorcycle speed or riding conditions.
  • BME (Bass Management Enhancement): Designed to produce more bass, no matter the volume. The active amplifier DSP (digital signal processing) continually adapts to speed and road noise and maximizes bass output to create powerful bass at any volume or speed.
  • Bridge Mounted Design: The offset midrange and tweeter speaker design eliminates acoustic reflection and maximizes audio output. The specific left and right midrange and tweeter are also aligned for the optimal riding position – the audio is always directed to deliver ideal on-road audio experience.
  • IDHS™ (Inductive Damping Heat Sink): The speaker fins push heat away from the voice coils to reduce speaker temperature and distortion to produce the clearest-possible audio.
  • Full Range Class-D Technology: High-efficiency amplifiers are designed to deliver more class-leading power with less electrical fatigue – they will not over-draw on the motorcycle electrical system.
  • ICC+: The Integrated Concealed Crossover boasts a hyper-efficient design and produces the clarity and output usually associated with in-home component speaker sets. The design allows for a quick installation.
  • The Harley-Davidson powered by Rockford Fosgate® App: The app allows riders to easily and quickly install and fine-tune the system themselves. Smart-Install makes initial installation and upgrades incredibly fast and easy. The Harley-Davidson powered by Rockford Fosgate® App even adapts for each new speaker added to the audio system and tailors the audio experience automatically.
  • Ease of Installation: A streamlined wiring harness, fewer required holes, and saddlebag location of no more than two amplifiers eases installation for the shop or the customer. No dealer software installation with a Digital Technical Tool is required; the Harley-Davidson powered by Rockford Fosgate® App programs and tests installation.

Harley-Davidson® Audio powered by Rockford Fosgate® Stage I and Stage II speakers are designed to fit perfectly in the original equipment speaker housing. Each kit is designed specifically for installation in the fairing, fairing lowers, Tour-Pak® luggage or saddlebag lids. Each kit includes left and right speakers and custom grilles. Installation requires purchase of a speaker installation kit and amplifier with installation kit. Stage I and Stage II speakers may be combined in a single system. Harley-Davidson powered by Rockford Fosgate® components feature a two-year limited warranty.

Harley-Davidson® Audio powered by Rockford Fosgate® Stage I Speakers

These high-performance two-way speakers feature a durable injection-molded woofer and a separate bridge-mounted tweeter. Each speaker is rated to handle up to 75 watts of power, and with two amplifiers up to eight speakers can be installed in a single system. These speakers deliver a significant upgrade in sound quality and power over the Original Equipment components.

Harley-Davidson® Audio powered by Rockford Fosgate® Stage II Speakers

Harley-Davidson® Audio powered by Rockford Fosgate® Stage II speakers are designed to deliver ultra-clear highs, super-clean mids, and ground-thumping bass. These amplified three-way speakers feature a durable injection molded woofer and a separate bridge-mounted midrange and tweeter speakers. Each speaker unit is rated to handle up to 150 watts of power and designed to deliver outrageous volume with less distortion for amazing sound even at highway speeds. With two amplifiers up to eight Stage II speakers can be installed in a single system.

Harley-Davidson® Audio powered by Rockford Fosgate® Amplifier

Powerful, intelligent amplifier technology has been engineered to perform in the demanding motorcycle environment. This new, compact amplifier (8.13″ x 5.39″ x 2.01″) is easy to install in the motorcycle saddlebag. A single amplifier can power two sets of Harley-Davidson® Audio powered by Rockford Fosgate® Stage I or Stage II speakers. Power rating is 50 watts per channel x 4 @ 4ohms; 100 watts per channel x 4 @ 2ohms.

Cooled and Heated Touring Seats

The temperature control technology built into the new Harley® Hammock Heated & Cooled and Sundowner™ Heated & Cooled seats for Harley-Davidson® Touring and Trike models are designed to extend and optimize the riding season. Both seats feature a remarkable cooling performance, and an improved heating function designed to reach selected temperatures twice as fast as previous heated seats. The heating/cooling system is self-contained within the seat, which uses the same pan shape as the standard Sundowner and Hammock seats. The seat can be easily removed after unplugging a single connection.

The thermoelectric heating/cooling system is contained entirely within the seat and utilizes a Peltier device, a type of heat pump that uses electrical current to transfer heat from one side of the device, in this case a mesh of very fine wire embedded in fabric below the seat cover, to the other side of the device. When electric current travels in one direction through the device, it draws heat away from the seat surface. If the current is reversed it heats the seat surface. There are no moving parts, and no gas or liquid to leak. A small fan in the seat base draws heat away from the device and exhausts it out the bottom. Installation requires the separate purchase of a model-specific electrical harness extension.

  • Greater comfort reduces fatigue and extends the riding season in any climate.
  • In testing with a baseline ambient temperature of 85 degrees the seat cover will cool down by 25 degrees in about 30 minutes, from your 98-degree body temperature to about 76 degrees. As you ride, the cooling function draws heat away from your body, which makes you feel cooler.
  • Dual Zone Control: Rider and passenger seating positions must use the same temperature mode (heat or cool) but each can adjust the level to individual preference or switch the function off.
  • A redesigned heating element reaches a selected temperature in only seven minutes.
  • Seam-sealed construction prevents rain or wash water from infiltrating the seat foam. No riding for hours on a squishy seat.

Sundowner™ Heated & Cooled Seat

The two-up Sundowner™ Seat is engineered to provide the maximum in long-riding comfort. The deep-bucket design puts most riders in an ideal touring posture, and the generous padding makes it comfortable for both the rider and passenger as the miles are adding up.

Harley® Hammock Heated & Cooled Rider and Passenger Touring Seat

The Harley® Hammock seat is a premium touring seat design, created for the rider who wants the ultimate in long-haul comfort. For the rider it features a sling-like fabric suspension system that acts like a hammock, providing two inches of suspension above the seat pan, topped with an additional two inches of traditional foam cushioning. This internal suspension prevents “bottoming out” and provides an improvement in comfort and endurance by isolating the rider from harsh road conditions. The passenger position features a multiple spring-board style suspension system along with two inches of traditional foam.

Screamin’ Eagle® Softail® Model High-Flow Exhaust System

The Screamin’ Eagle® High-Flow Exhaust for Softail® models provides bolt-on performance and is optimized for use with Screamin’ Eagle Milwaukee-Eight® 128/131 Stage IV Kits or the Screamin’ Eagle 131 Crate Engine in Softail models.
