Havoc GP-1 HD Dyna/Sportster Gauge Stereo Head Unit

If you want a clean, compact head unit without hanging a big stereo off your bars, this is the answer. The Havoc GP-1 Dyna/Sportster Gauge Stereo Head Unit pairs the Aquatic AV GP-1 gauge stereo with a Havoc Motorcycles billet pod and a billet handlebar clamp so the system mounts solidly and looks like it belongs on the bike—not like an add-on.

The GP-1 gives you modern playback options in a small, glove-friendly gauge format, while the Havoc billet pod protects the unit and keeps the cockpit tidy. It’s the perfect foundation for a full system later, or a simple standalone upgrade now.

• IMPORTANT NOTE: SPEAKERS SHOWN IN THE IMAGE OF THE STEREO ON THE MOTORCYCLE ARE NOT INLUDED WITH THIS COMPONENTS. FOR A KIT THAT INCLUDES SPEAKERS, GO TO:   Havoc Roar Stereo HRS-144.2-DC Streetline Bar Kit – Dyna / Sportster / Custom

Installation note: Please confirm your clamp bolt pattern before ordering.

Why Bluetooth + SiriusXM Streaming + USB + AM/FM Just Works

This head unit gives you the best of every world  - streaming when you feel like it, offline music when you need it, and radio when you just want instant sound.

• Bluetooth + the SiriusXM app lets you pull in channels and playlists off your phone in your jacket pocket, plus it plays the usual suspects like Spotify and Apple Music.

• USB playback is the no-excuses option: load up a stick with your favorites and you’ve got clean, reliable music when you take that Sunday morning ride free of the phone, or when cell coverage drops or you don’t want to burn data.

• AM/FM is still the ultimate fallback for your fav DJs or radio shows: tap it on and you’ve always got something playing, plus local updates like weather and news when you want them.

Bottom line: your music isn’t depending on one link. You’ve got premium streaming, solid offline playback, and always-on radio in one compact setup.

Fitment

This mount is designed around Harley’s long-running handlebar/riser standards used from about 1973-present on most motorcycles using a 1-inch bar at the riser/clamp point, as long as the clamp location is available and not currently being used for gauges. 

• Works with 1-inch bars at the riser (common on many Dynas and Sportsters)

• Some newer Dyna models run 1.25-inch bars at the riser — this kit will not fit unless the risers and bars are changed.  This is for 1-inch at the clamp point.

• Requires an open clamp location (i.e., not already occupied by a gauge mount, accessory clamp, or other hardware)

This kit is offered with two clamp bolt patterns:

• Parallel bolt holes

• Offset bolt hole pattern

Select the bolt pattern that matches your existing clamp/riser setup, then choose Black or Chrome to match your build.
