Havoc GP1 Road King Head Unit Kit
A real stereo for your Road King — without adding a fairing.
KEEP THE ROAD KING A ROAD KING
The Road King doesn't need a fairing to have a proper stereo. It just needed someone to rethink where the stereo belongs.
The Havoc GP1 Road King Head Unit Kit puts an Aquatic AV GP1 gauge stereo directly into a custom-machined billet aluminum Road King nacelle cap. The result is a clean, integrated installation that gives you a real head unit, a real display and real controls — without changing the character of the motorcycle.
No generic handlebar bracket. No Bluetooth box hidden under the seat. No phone-only controls. And no fairing.
RIGHT WHERE YOU RIDE.
THE RIGHT PLACE FOR THE HEAD UNIT
The nacelle is one of the most natural places on a Road King for a stereo. It's directly in front of the rider, easy to see and easy to reach without taking your attention away from the road.
The GP1's gauge-style design makes it possible to integrate the stereo into the nacelle rather than hanging another piece of equipment off the handlebars. The display is visible at a glance, the controls are right where you expect them to be, and the compact design keeps the cockpit clean.
Bluetooth when you want it. AM/FM radio when you want it. Proper controls when you need them.
AQUATIC AV GP1 GAUGE STEREO
At the heart of the kit is the proven Aquatic AV GP1, a compact, weather-ready gauge stereo designed for motorcycle and powersports applications.
- Bluetooth audio streaming
- AM/FM radio
- USB connectivity
- Audio playback from connected devices
- SiriusXM app audio support through your connected device
- Compact gauge-style design
- Weather-ready construction
It's a real head unit — not simply a Bluetooth receiver hidden somewhere on the bike.
BUILT AROUND THE ROAD KING
We didn't start with a generic stereo mount and try to make it fit. The GP1 is installed into a Havoc-designed billet aluminum gauge pod, which is then integrated into a replacement Road King nacelle cap.
That gives the stereo a rigid, vibration-resistant mounting point while making the nacelle cap itself part of the installation. The result is substantially cleaner than an aftermarket bracket attached to the original nacelle.
Machined billet. Purpose-built mounting. Factory-style integration.
CHROME OR BLACK. YOUR ROAD KING, YOUR WAY.
The GP1 kit is available in two finishes so it can work with everything from a traditional chrome Road King to a modern blackout build.
CHROME
Precision-machined aluminum components are carefully prepared and polished before being triple chrome plated for a deep, brilliant finish.
Real chrome. Show-bike shine. Old-school beautiful.
SATIN BLACK
The billet components are carefully machined and finished before being coated in a durable satin black powdercoat.
The satin finish works naturally with Harley-Davidson blackout and Special trim, as well as custom bikes built around a darker aesthetic.
One design. Two very different personalities.
BUILT FOR YOUR ROAD KING
The Havoc GP1 Road King kit is available for both major Road King nacelle generations. Select the correct year range when ordering.

THIS IS THE HEAD UNIT FOUNDATION
The GP1-RK kit includes the head unit and its billet Road King mounting system only. Speakers and amplifiers are not included.
Pair it with Havoc Roar speaker pods and amplification to build the system that fits your bike and the way you ride.
BUILD YOUR HAVOC ROAR SYSTEM
The GP1-RK is the head unit foundation used in the Havoc Roar Road King audio family. Start with the clean, compact GP1 installation and add the speaker and amplifier configuration that suits your bike.
From the compact 144.2 Sport system to multi-speaker configurations with highway-bar and saddlebag speakers, the Havoc Roar system is designed as a complete Road King audio platform rather than a collection of unrelated aftermarket parts.
NO COMPROMISE.
JUST A BETTER WAY TO PUT A STEREO ON A ROAD KING.
