    4 Stars
    Decent, audible sound, easy install.
    Kinda took a chance on this after reading mixed reviews...beyond impressed.I was between this and the Plex for my FXBB, figured I’d go this route first seeing as the Plex is over a G with marine quality speakers.Sound quality is exactly what I expected. Nowhere near bagger quality, but audible at virtually all speeds, even with a full face/visor down going 80 on the freeway. If I’m only wearing a half shell and cruising around town, it’s actually too loud IMO.I do have it inside a fairing though, which definitely helps project the sound back to my head. I can see this not working great just sitting in open bars.The sound has no bass, but that is by design. To make such a tiny soundbar audible on a motorcycle, it needs to be heavily eq’d towards hi/mids, so the sound cuts through the wind noise. Even baggers have relatively low bass unless there’s a dedicated sub or low-eq’d speaker (usually behind the rider). That’s just how sound works. Motorcycle audio doesn’t thump, you won’t be able to hear it, and the bass will drown out anyway.Quality audio sources also make a HUGE difference.I’ve had it side by side with a Plex system and it’s only marginally worse which makes me glad I didn’t drop all that cash on one (the Plex has a bit fuller sound though). I might try adding 2 marine speakers with the amp out at some point to beef up the sound a little.Install was a breeze, took about 30 minutes. If you can disconnect your battery and lift your tank, you can do this. It just connects to your battery and then splices into an an accessory wire (I used my rear running lights). I ran the wiring under my tank and then up through my risers with the rest of the factory harness. Everything is included.Only gripe was the mounting hardware and finish is kinda rough - it will easily scratch your bars and the sound bar itself if you aren’t careful. Not really an issue for me, but some people might whine about that. I have some scuffs from moving it around.Bottomline, if you want decent motorcycle audio for a moderate price that installs in under an hour, go for it. It could certainly be $100 or so dollars cheaper, but there aren’t many alternatives - either super expensive custom-ish solutions, or el cheapo junk that looks and sounds horrible.

    Reviewed in the United States on December 28, 2022
    Pros:
    Decent sound quality and easy connection to phone.
    Built in controls for navigating next/previous tune and raising/lowering volume.
    Connects directly to the battery and starter line to only come on with the bike being on so it doesn't kill your battery.
    Built-in USB charger to charge up your phone/device for those long hauls.
    Water-resistant electronics are great for all-weather riding.

    Cons:
    Not the best at freeway speeds but decent for running around town (in ref. to volume).
    Price is a bit high for something that can't be used for all types of riding.

    I put over 20K miles on a bike with one of these and the quality never lessened. There aren't many cons. I know the sound quality isn't as good as the Plex but the USB charger makes it blow the Plex away.

    5.0 out of 5 stars This Speaker is Phenomenal
    Reviewed in the United States on April 17, 2021
    I’ve been wanting this speaker for months and I couldn’t pull the trigger because it’s pretty pricey, and what if you spend all that money and spend time on installation only to find out it doesn’t sound that good or you can’t hear it after hitting a certain speed like some other buyers have mentioned? Well, I finally decided to do it after the weather finally broke and I have zero buyer’s remorse. The speaker sounds absolutely awesome. Installation took about two hours, but that’s only because it took time to research things about my bike and figure out how to best run the wiring; if I had to install this speaker again, it would probably take 30-45 minutes give or take.

    Once it was on, it was as simple as activating Bluetooth on my phone. The speaker immediately connected, and I was playing music in less than 10 seconds. No issues whatsoever.

    Others have reported not being able to hear their music over 45-50 miles per hour, which was really my biggest concern. My bike is a 2021 Indian Scout Bobber, 1200cc’s with a Vance & Hines Twin-Slash exhaust. Simply put, it’s loud. There is no wind protection at all. I’ve ridden at 85mph since installing the speaker and I can tell you that I can not only still hear music but I can identify the song, it’s not just noise. Granted, at that speed it doesn’t sound great, but I don’t ever ride at those speeds anyway. At 45-50, it’s clear as day with full face shield helmet on.

    Being able to listen to my music on the bike has definitely added another level of enjoyment to my riding experience. You won’t be disappointed if you invest in this speaker for your motorcycle.

    Decent speaker. Put this on my girls Sportster. Was a little bit of a pain to mount but once in place looks good. Others may have less trouble. It was probably just the handle bars that she has. The finish does scratch easily. So take your time. As one person mentioned in a previous review, I highly suggest getting the "Electrical connection upgrade kit" from Harley. Part # 72673-11. Makes wiring so much easier. Sound is decent. No bass to speak of but still sounds good.

    5.0 out of 5 stars Works Perfectly on an Indian Scout
    Reviewed in the United States on June 26, 2022
    Installed and works perfectly on my wife's Indian Scout! Installs easily between the handlebars and the windshield, if any. Indian includes a spare wire from the ignition. Whatever connector that is fits with the connector provided by Kuryakyn. No manual splicing needed, at least on an Indian bike (and probably most newer bikes). This way, it's wired into the ignition so the speaker turns off when the bike turns off.

    The speaker system includes a USB port for charging your phone or whatever you want to use it for. The sound quality is great to me. I don't know a lot about sound, I'm not a musician, I've never installed aftermarket speakers in a car or truck, I don't generally jack with equalizers (because stock is fine). I'm not a sound fanatic. To me, the sound quality is better than a lot of motorcycles with fixed fairings that have speakers. Does this sound ok? Yeah, sounds great and rich to me.

    We play streaming music and mp3 music, both from a phone. I connected the phone to the speaker over Bluetooth. The Bluetooth connects easy. When I mute my radio on my motorcycle, I can hear my wife's Road Thunder music from her bike, probably 6-8 feet away. It's plenty loud and we've never had it anywhere near max volume. No complaints. Solid purchase. Sound snobs might find something to whine about, as you can see in other reviews, but I honestly don't understand what they are talking about.

    Reviewed in Canada on May 18, 2023
    Nice Soundbar. It’s quite loud and clear. Some distortion at maximum volume, but one notch lower and it’s all clear. It’s loud enough to be heard over my straight pipes and riding at 60 miles/hr. Obviously it’s not bass speaker, but not expected from 3” woofers. The few hundred max wattage rating is bogus. It’s the rms wattage that counts and it’s just over 23 watts per channel. If this speaker was 300 watts max, or about 150 watts rms, it would be very loud, especially pointing directly in your face. Easy to mount and wiring is very good. Bluetooth connection is top notch. I would give it 5 stars but price is the factor that many riders would be turned off. Would I buy again? Most likely.
