HARLEY DAVIDSON

Upgrade your Harley-Davidson touring bike with Focal Inside Plug & Play speaker kits from Focal Australia. These motorcycle-specific packages are designed to fit OEM fairing and factory speaker locations, using model-specific mounting and plug-in connectors for a clean, reversible installation with no cutting or custom fabrication. Built with weather-resistant materials and high-efficiency drivers, they are engineered to handle real-world riding conditions while delivering powerful, detailed sound that cuts through wind and engine noise.

Whether you’re running a factory head unit or an upgraded amplifier, Focal Harley-Davidson kits provide stronger mid-bass, clearer vocals and smoother highs than the stock system, so your music stays loud, clean and enjoyable on long highway runs and daily rides alike.

Upgrade your compatible Harley-Davidson touring motorcycle with a purpose-designed Focal Inside speaker system engineered for the demands of open-road listening.

Unlike a conventional car interior, a motorcycle does not provide an enclosed and acoustically controlled cabin. Its speakers must compete with wind, engine, exhaust, road and helmet noise while also enduring vibration, temperature changes and exposure to outdoor conditions.

Focal Harley-Davidson speaker kits are designed to deliver:

• Clearer vocals
• More detailed high frequencies
• Stronger and better-controlled mid-bass
• Greater output with less distortion
• Improved sound projection toward the rider
• Better clarity at touring and motorway speeds
• Secure integration into compatible factory fairings
• An OEM-style appearance using dedicated grilles and mounting components

Focal Australia currently offers four main Harley-Davidson speaker solutions:

• HDA 165 – 1998–2013
• HDK 165 – 1998–2013
• HDA 165 – 2014 UP
• HDK 165 – 2014 UP

The HDA kits use Focal Access cone technology and are designed to provide an efficient and highly effective improvement over compatible factory speakers.

The HDK kits use Focal’s premium K2 Power cone technology and are intended for riders seeking greater output, stronger dynamics, improved definition and more advanced system performance.

Published Australian applications include selected:

• Road Glide models
• Street Glide models
• Electra Glide models
• CVO Limited models
• CVO Ultra Limited models
• Compatible aftermarket Batwing fairings

Product names such as “1998–2013” and “2014 UP” identify the generation for which the kit was developed. They do not confirm compatibility with every Harley-Davidson made during or after those years.

Newer Harley-Davidson motorcycles can have redesigned fairings, different speaker enclosures, factory Rockford Fosgate audio, dedicated amplifiers, digital signal processing and infotainment systems requiring electronic configuration.

Compatibility should always be confirmed using:

• Exact motorcycle model
• Production year
• Factory or aftermarket fairing
• Original speaker locations
• Factory head unit
• Factory amplifier
• Existing speaker impedance
• Speaker-enclosure depth
• Previous audio modifications
• Desired system configuration

For the best results, an Authorised Focal Australia Dealer can identify the motorcycle, inspect its existing audio system and confirm the correct speakers, adaptors, amplification and installation method before products are ordered.

1. What are the best Focal speakers for a Harley-Davidson?

The best Focal speaker kit depends on the motorcycle’s model, production year, factory audio equipment and the level of performance the rider wants to achieve.

Focal offers two main performance levels for compatible Harley-Davidson applications:

• HDA 165 with Access cone technology
• HDK 165 with K2 Power cone technology

The HDA 165 can be an excellent starting point for riders who want:

• Clearer vocals
• Improved treble
• Stronger mid-bass
• Better sound at moderate and higher volume
• Efficient operation from a compatible factory radio
• OEM-style integration
• A substantial improvement without designing a completely new system

The HDA kit has a nominal impedance of 4 ohms and high sensitivity, making it suitable for many compatible factory-powered installations.

The HDK 165 is the premium option. It may suit riders seeking:

• Greater acoustic output
• Stronger dynamics
• More detailed midrange
• Improved high-frequency definition
• Better control at elevated volume
• A more powerful amplified system
• Premium K2 Power performance

The HDK kit has a nominal impedance of 2 ohms. Its lower impedance and greater power capability mean amplifier compatibility must be checked carefully.

The HDK also has a deeper magnet assembly than the HDA. In some motorcycles, the original speaker enclosure must be modified to provide sufficient clearance.

The more expensive HDK is not automatically the correct choice for every motorcycle. If the factory radio or amplifier cannot properly control the speaker, a well-matched HDA installation may perform better than an incorrectly powered HDK system.

The complete audio system should be considered rather than judging the speakers in isolation.

2. Are Focal Harley-Davidson speakers genuinely Plug & Play?

The Focal HDA and HDK kits are motorcycle-specific Focal Inside products developed for compatible Harley-Davidson applications.

Depending on the exact kit and motorcycle, the package can provide:

• Dedicated 6.5-inch speakers
• Separate compression tweeters
• Motorcycle-specific grilles
• Mounting components
• Compatible electrical connections
• Integration into original speaker locations
• An OEM-style finished appearance

This provides a much more direct installation than adapting a conventional automotive speaker to a motorcycle fairing.

However, “Plug & Play” does not mean that every kit fits every Harley-Davidson.

True compatibility still depends on:

• Model
• Production year
• Fairing generation
• Speaker-enclosure design
• Speaker impedance
• Factory amplifier
• Available mounting depth
• Connector configuration
• Existing audio modifications

Some premium HDK installations require modification to the speaker enclosure because the K2 speaker has a deeper magnet.

Newer Street Glide, Road Glide and CVO models may also use redesigned fairings, different speaker housings, Rockford Fosgate equipment or digitally configured audio systems that are outside the older published applications.

The correct interpretation is that Focal offers Plug & Play integration for confirmed compatible Harley-Davidson applications—not universal fitment across the entire Harley-Davidson range.

3. Which Harley-Davidson models are compatible with Focal speakers?

Focal Australia’s published compatibility information currently identifies selected touring motorcycles across two principal year groups.

Published 1998–2013 applications include selected:

• Road Glide
• Street Glide
• Electra Glide

Published 2014-onward applications include selected:

• Road Glide
• Street Glide
• Electra Glide
• CVO Limited
• CVO Ultra Limited

The current Australian chart applies more specific ending years to several of these models. For example, it identifies Road Glide applications through 2019, selected Street Glide and Electra Glide applications through 2022, and selected CVO applications through 2020.

These model-year limitations are important because Harley-Davidson has introduced major fairing, infotainment and factory-audio changes.

The 1998–2013 kits may also be used with certain compatible Batwing-style fairing applications. Potential examples can include fairings fitted to selected:

• Fat Boy
• Heritage
• Low Rider
• Road King
• Slim
• Softail
• Sportster

An aftermarket Batwing fairing should be assessed independently. Fairings from different manufacturers can use different:

• Speaker openings
• Mounting patterns
• Enclosure depths
• Grilles
• Wiring
• Amplifiers
• Inner-fairing structures

A motorcycle appearing in a general model list does not replace checking the complete compatibility chart.

4. What is the difference between the Focal HDA and HDK Harley-Davidson kits?

The HDA and HDK kits are different performance levels with different electrical and physical requirements.

Focal HDA 165

The HDA 165 uses Focal Access cone technology.

Its characteristics include:

• 4-ohm nominal impedance
• 80-watt nominal power handling
• 160-watt maximum power handling
• 91 dB sensitivity
• Aluminium inverted-dome compression tweeters
• Butyl surrounds
• Dedicated Harley-Davidson grilles
• High efficiency for noisy motorcycle environments

The HDA is designed to provide balanced, controlled sound and a worthwhile improvement when operated from a compatible factory head unit or appropriately matched amplifier.

Focal HDK 165

The HDK 165 uses Focal K2 Power cone technology.

Its characteristics include:

• 2-ohm nominal impedance
• Higher power capability
• 92.5 dB sensitivity
• K2 inverted-dome compression tweeters
• Greater dynamic output
• Improved detail and control
• Dedicated Harley-Davidson grilles
• A deeper 74 mm mounting depth

The K2 cone combines rigidity, low mass and controlled damping. This allows it to deliver strong dynamics, clear midrange and detailed high-frequency performance in demanding conditions.

The HDK’s lower impedance, higher power capability and deeper magnet mean it requires more careful assessment than the HDA.

The choice should be based on the complete system—not merely the colour, price or published power rating of the speaker.

5. What is the difference between the 1998–2013 and 2014-up Focal kits?

The two generations are designed around different Harley-Davidson fairings, enclosures, grilles and mounting arrangements.

The 1998–2013 kits are intended for confirmed applications from the earlier generation of Harley-Davidson touring motorcycles.

The 2014-up kits were developed for the revised systems introduced with later touring platforms.

Differences can include:

• Speaker mounting position
• Factory grille
• Inner-fairing shape
• Speaker-enclosure volume
• Mounting-hole pattern
• Wiring connector
• Available installation depth
• Tweeter position
• Factory radio output
• Factory amplifier
• Speaker impedance
• Audio equalisation

A 6.5-inch speaker from one generation should not be assumed to fit the other generation simply because its nominal diameter is the same.

The “2014 UP” product description also requires qualification.

It means the kit belongs to the 2014-onward product generation. It does not guarantee compatibility with every Harley-Davidson produced from 2014 to the present.

Later CVO, Street Glide and Road Glide motorcycles can use redesigned fairings, Skyline OS infotainment, different speaker housings and Harley-Davidson Audio powered by Rockford Fosgate systems.

The specific model and year must therefore be checked against the current Focal Australia compatibility information.

6. Can Road Glide, Street Glide and Electra Glide speakers all use the same kit?

Not automatically.

Although these motorcycles may share similar production periods and some audio components, their fairing structures are different.

The Street Glide and many Electra Glide models use a fork-mounted Batwing-style fairing.

The Road Glide uses a frame-mounted Sharknose-style fairing.

These differences can affect:

• Speaker angle
• Enclosure shape
• Mounting depth
• Grille design
• Wiring route
• Amplifier location
• Heat management
• Ease of disassembly
• Sound projection toward the rider

The installation method can also differ even where the same Focal product is listed.

Before installation, the dealer should confirm:

• Exact model designation
• Production year
• Standard or CVO specification
• Original or aftermarket fairing
• Factory speaker enclosure
• Existing amplifier
• Available depth behind each speaker
• Clearance around wiring and ventilation
• Whether previous modifications have been made

A product being suitable for one 2014 Street Glide does not mean it will automatically suit a recent Road Glide with a redesigned fairing and factory Rockford Fosgate system.

7. Can a Harley-Davidson CVO or premium factory audio system be upgraded?

Potentially, but CVO and premium audio systems require more investigation than a basic two-speaker factory system.

Depending on model and year, a premium Harley-Davidson audio system may include:

• Fairing speakers
• Saddlebag speakers
• Tour-Pak speakers
• Dedicated amplification
• Multiple amplifier channels
• Factory equalisation
• Automatic volume adjustment
• Channel-specific filtering
• Digital signal processing
• Rockford Fosgate components
• Electronic configuration through an app or infotainment system

Replacing only the front speakers can change the tonal balance between the fairing, saddlebag and rear speakers.

The installer should confirm:

• Impedance of every existing speaker
• Factory amplifier power
• Number of amplifier channels
• Frequency range assigned to each channel
• Factory crossover points
• Signal polarity
• Existing equalisation
• Speaker-level output voltage
• Whether electronic configuration is required
• Whether the system has previously been modified

The Focal Australia chart currently identifies selected CVO Limited and CVO Ultra Limited applications from 2014 to 2020.

Later CVO models should not be assumed compatible because newer motorcycles can use substantially different factory audio hardware and redesigned speaker locations.

8. Can the original Harley-Davidson radio and infotainment system be retained?

In many installations, yes.

Retaining the original Harley-Davidson radio or infotainment system can preserve:

• Factory appearance
• Handlebar audio controls
• Bluetooth
• Radio functions
• Navigation
• USB audio
• Telephone integration
• Vehicle information
• Automatic volume functions
• Factory system settings

A compatible Focal speaker upgrade can often be integrated after the original source unit.

However, the installer must determine whether the existing system can correctly power the selected speakers.

This is particularly important when moving between:

• Original factory speakers
• 4-ohm HDA speakers
• 2-ohm HDK speakers
• Factory-amplified systems
• Aftermarket amplifiers
• Rockford Fosgate-equipped systems

Some Harley-Davidson audio systems require electronic configuration after speakers or amplifiers are added. Depending on the system, this may involve the Harley-Davidson audio application, Skyline OS prompts or dealership programming.

Incorrect configuration can result in:

• No audio
• Incorrect channel allocation
• Poor tonal balance
• Reduced output
• Excessive distortion
• Incorrect equalisation
• Amplifier protection
• Unexpected battery drain

The requirement for programming or configuration should be confirmed before the installation begins.

9. Will Focal speakers make my Harley-Davidson louder and clearer at highway speeds?

A correctly selected and installed Focal system can provide a significant improvement in clarity, projection and usable output.

Motorcycle speakers must overcome:

• Wind turbulence
• Engine noise
• Exhaust noise
• Tyre noise
• Traffic noise
• Helmet attenuation
• Open-air loss of lower frequencies

Focal’s Harley-Davidson kits use high-sensitivity drivers and compression tweeters designed to project sound effectively in an open-air environment.

Potential improvements include:

• Clearer lead vocals
• Better speech intelligibility
• More audible cymbals and guitar detail
• Stronger mid-bass
• Reduced harshness
• Cleaner output at elevated volume
• Better balance between music and surrounding noise

However, speaker replacement alone cannot eliminate every limitation of motorcycle listening.

Actual results depend on:

• Fairing design
• Windscreen height
• Rider height
• Helmet type
• Riding speed
• Exhaust system
• Head-unit power
• Amplifier power
• Source recording quality
• Audio compression
• Speaker aiming
• System tuning

The objective should be clean and intelligible sound—not simply maximum volume.

The rider must still be able to hear traffic, emergency vehicles, warning signals and other important sounds. Excessive volume can damage hearing and reduce situational awareness.

10. Does a Harley-Davidson speaker upgrade require an amplifier?

Not every HDA installation requires a separate amplifier.

The efficient 4-ohm HDA speakers may produce a worthwhile improvement from a compatible factory radio or amplifier.

This can be suitable for riders wanting:

• Clearer sound
• Improved tonal balance
• Better high-frequency detail
• Stronger mid-bass
• A straightforward factory-location upgrade

An amplifier becomes more beneficial when the owner wants:

• Greater volume at speed
• More dynamic output
• Improved control
• Reduced distortion
• Additional speaker pairs
• Saddlebag or Tour-Pak speakers
• Premium HDK performance
• A more extensively tuned system

The 2-ohm HDK speakers must only be used with an amplifier or factory source confirmed as stable at that impedance.

An unsuitable amplifier can:

• Overheat
• Enter protection mode
• Distort
• Damage speakers
• Reduce reliability
• Drain the motorcycle battery
• Produce less usable output than expected

The amplifier should be chosen according to:

• Speaker impedance
• RMS power requirements
• Number of channels
• Available electrical capacity
• Installation space
• Heat dissipation
• Weather exposure
• Vibration resistance
• Standby current
• Turn-on and shutdown behaviour

A motorcycle’s charging system has less reserve capacity than many cars. The total electrical load must therefore be assessed before a high-powered amplifier system is installed.

11. Can Focal speakers be added to the saddlebags or Tour-Pak?

Potentially, but the current HDA and HDK fairing kits should not automatically be treated as direct-fit saddlebag or Tour-Pak solutions.

Rear speaker installations can involve:

• Factory saddlebag lids with speaker locations
• Replacement audio saddlebag lids
• Custom-machined adaptors
• Tour-Pak speaker pods
• Existing factory speakers
• Additional amplifier channels
• New weather-resistant wiring
• Quick-disconnect connections
• Custom grilles
• Acoustic sealing

Before additional speakers are installed, the system should be designed as a whole.

The installer should consider:

• Number of available amplifier channels
• Total amplifier impedance
• Front-to-rear balance
• Speaker efficiency
• Speaker aiming
• Crossover frequencies
• Wiring route
• Saddlebag removal
• Water sealing
• Luggage space
• Added weight
• Connector durability

Rear speakers can increase output and provide a fuller sound while riding. However, excessive rear level can pull the apparent soundstage behind the rider and reduce vocal clarity from the fairing speakers.

Correct level setting, crossover adjustment and system tuning are essential.

Where the saddlebags need to remain removable, suitable sealed quick-disconnect wiring should be incorporated into the installation.

12. Are Focal Harley-Davidson speakers waterproof?

Focal’s Harley-Davidson kits are designed for demanding motorcycle environments and use durable materials suitable for vibration, temperature changes and normal outdoor exposure.

However, “designed for motorcycle use” should not automatically be interpreted as permission to submerge the speakers or direct high-pressure water at them.

During washing, avoid directing high-pressure spray into:

• Speaker grilles
• Tweeters
• Fairing openings
• Amplifier vents
• Wiring connectors
• Radio controls
• Electrical enclosures

The installation should include appropriate:

• Sealed or protected connectors
• Correctly fitted grilles
• Secure wiring
• Drainage paths
• Moisture protection
• Corrosion-resistant fasteners
• Cable support
• Fairing reassembly

Any stated water-resistance or environmental rating should be confirmed from the specification for the exact product rather than assumed from the motorcycle application.

After riding in heavy rain or washing the motorcycle, the system should be inspected if it develops distortion, intermittent operation or a channel imbalance.

13. When is the 5-inch-to-6.5-inch Harley speaker adaptor required?

The Focal Harley speaker ring adaptor is intended to convert selected 5-inch factory speaker mounting locations to accept compatible 6.5-inch speakers.

A correctly designed adaptor can:

• Position the speaker securely
• Maintain correct alignment
• Provide a rigid mounting surface
• Improve the acoustic seal
• Reduce unwanted resonance
• Preserve an OEM-style appearance
• Avoid unnecessary cutting of the fairing

The adaptor should only be used in a confirmed application.

Before installation, check:

• Original opening diameter
• Mounting-hole pattern
• Adaptor thickness
• Speaker cut-out requirement
• Magnet diameter
• Total speaker depth
• Grille clearance
• Fairing clearance
• Wiring clearance
• Enclosure volume
• Tweeter position

The adaptor does not solve every fitment issue.

In particular, the deeper HDK K2 speaker may still require enclosure modification to provide magnet clearance. The Focal Australia compatibility notes specifically warn about this requirement for selected applications.

The enclosure should not be cut or altered until the exact speaker, adaptor and available depth have been physically confirmed.

14. Can I install Focal Harley-Davidson speakers myself?

Some experienced owners may be capable of installing a straightforward Focal Inside kit, particularly where the application is confirmed and no enclosure modification or additional amplification is required.

However, professional installation is strongly recommended where the motorcycle has:

• A CVO audio system
• Factory amplification
• Rockford Fosgate audio
• Multiple speaker pairs
• A replacement amplifier
• Saddlebag speakers
• Tour-Pak speakers
• Custom wiring
• A non-standard fairing
• Previous audio modifications
• An HDK kit requiring enclosure modification
• Electronic configuration requirements

A professional installation should include:

• Compatibility confirmation
• Safe battery disconnection
• Correct fairing removal
• Inspection of existing wiring
• Secure speaker mounting
• Correct polarity
• Weather-conscious connections
• Vibration-resistant cable support
• Amplifier gain adjustment
• Crossover configuration
• Final audio testing
• Verification of charging voltage
• Confirmation that the motorcycle shuts down correctly

Incorrect fairing removal can damage painted panels, clips, wiring, lighting, switches or infotainment equipment.

Poorly supported wiring can rub against the frame or fairing, creating intermittent faults or short circuits.

An incorrectly configured amplifier can damage the speakers even when its advertised power rating appears suitable.

15. How do I confirm compatibility, and what will a Harley-Davidson audio upgrade cost?

Begin with the motorcycle’s complete information.

Provide the dealer with:

• Exact Harley-Davidson model
• Model code where available
• Production month and year
• Standard or CVO specification
• Factory or aftermarket fairing
• Factory head unit
• Factory amplifier
• Number and location of speakers
• Saddlebag or Tour-Pak speakers
• Existing Rockford Fosgate equipment
• Previous audio modifications
• Desired performance level
• Typical riding conditions

Physical compatibility can be affected by:

• Speaker diameter
• Cut-out diameter
• Mounting-hole pattern
• Magnet diameter
• Mounting depth
• Grille clearance
• Enclosure shape
• Fairing structure
• Adaptor thickness
• Wiring clearance

Electrical compatibility can be affected by:

• Speaker impedance
• Factory amplifier power
• Aftermarket amplifier stability
• Channel frequency range
• Factory equalisation
• Crossover filtering
• Electronic configuration
• Charging-system capacity
• Amplifier standby current

The cost will depend on:

• HDA or HDK speaker selection
• Motorcycle generation
• Number of speaker pairs
• Required adaptors
• Enclosure modification
• Amplifier installation
• Saddlebag or Tour-Pak speakers
• Wiring requirements
• Fairing disassembly
• System configuration
• Final testing and tuning

A two-speaker HDA upgrade on a compatible motorcycle will generally be less complex than a multichannel HDK system with amplification and saddlebag speakers.

It would be misleading to provide one standard Harley-Davidson audio-upgrade price without first identifying the motorcycle and existing audio system.

Genuine Focal products purchased through an Authorised Focal Australia Dealer receive the applicable Australian Focal product warranty and support.

Motorcycle, product and installation warranty responsibilities may be separate. Questions concerning the motorcycle’s factory warranty should be confirmed with Harley-Davidson or the selling dealer.

Upgrade Your Harley-Davidson with Focal Sound

Whether you ride a Road Glide, Street Glide, Electra Glide or compatible CVO touring motorcycle, there may be a dedicated Focal Inside speaker upgrade available.

Focal HDA systems provide an efficient and effective improvement using Access cone technology, high-sensitivity drivers and aluminium compression tweeters.

Focal HDK systems bring premium K2 Power technology, greater dynamic performance and higher output to appropriately powered installations.

Depending on the motorcycle and desired result, the complete upgrade may include:

• HDA or HDK fairing speakers
• Dedicated Harley-Davidson grilles
• Speaker mounting adaptors
• Factory radio integration
• Additional amplification
• Saddlebag speakers
• Tour-Pak speakers
• Weather-conscious wiring
• Electronic system configuration
• Professional testing and tuning

Compatibility must be confirmed for the exact model and production year.

The “1998–2013” and “2014 UP” descriptions identify product generations and should not be interpreted as universal fitment across every Harley-Davidson produced during those periods.

A correctly designed and installed Focal system can provide clearer vocals, stronger mid-bass, improved high-frequency definition and greater usable output while preserving the motorcycle’s original appearance and controls.
