Customer Reviews Posted:

Dimensions were skewed but think I'll be able to retrofit....

 Mark Norman Posted:

Looks great, though yet to be fitted!! Further review later.

love it - loud - lets them know your there

 flhtrider Posted:

Horn mounted to the OEM horn shock mount. Finding a place to mount the relay was a challenge; I put it under the left side cover on my 1989FLHTC where the air valve for the rear shocks mounts, just re-directed the plumbing to accomodate the relay and terminal block. The horn is great - very loud - very attention-getting. Good product.

 jonhannum Posted:

Great horn, great sound for the price

 rick.lange Posted:

Awesome. I love it. Cagers can hear me now.

 craigpindell Posted:

Great replacement for the cheap stock horn. Loud and gets attention. Beautiful design as well. Posted:

Horn sounds great, but not sure it's very durable. My 1st didn't work and the 2nd works most of the time. Loud when it does though. Swapping it for quad trumpet horns.

 pt40fathoms Posted:

Piece of garbage!! Worked for less than an hour. Sounded nice when mounted and on the road, but after a short drive, it stopped and only blew air?! Found that on of the plastic horns cracked! No impact signs, and mounting was perfect. After close inspection, it appears that it was glued together? WTF! NOT IMPRESSED!! Do NOT buy this piece of crap! Posted:

Bought for a spare Posted:

Bought it for my Rocker (2009) and it took me 20 min to install. Twice as powerful compared with my previous horn and I am very happy.

 garyjeffbiker Posted:

FANTASTIC. I Loved the First one, so Much, I Bought another, for my other Cruiser!

 R Duke Posted:

This little dude really puts out a good sound and gets drivers attention. Easy to install with slight modification to the mounting bracket. Great price considering what other air horns cost.

 Shinriky Posted:

Noise is great and loud, but installation is a pain... Do not expect a 5 min job to install it. Nevertheless, with a bit of patience it's feasible.

 theciscokid Posted:

looking forward to using and hope is as advertised.


I love this Horn, it's sound is like a Mack Truck. But it's only as big as your Fist. Make sure you order the Wire Kit for Wolo Horn and checkout Chrome cover available as well. Looks great sounds excellent, can't wait for someone to cut me off again lol. Peter Hervey Bay Australia.

 Mr. Joel Posted:

Loud like a freight train! I love it!

 saslee Posted:

great looking and sounding horn, will defiantly be able to be heard now.

 caretaker1965 Posted:

Horn hooked right up after a little bit of modification and is loud and clear !!

 gwensell Posted:

Easily attached to existing H-D horn mounting bracket. Very happy with sound and ease of mounting. Instructions are generic instructions. Not for anything specific. With marginal mechanical skills, application is a breeze.

 patr667 Posted:

I had to install a relay (provided) but had to procure all the components ( no big deal). I'm not a huge fan of the fact it only attaches with one bolt and kinda just slips on. I didn't want to drill any holes so I used the factory mount point and it looks good. Horn is chromed plastic, but looks nice. A big larger then expected. And while its way louder then factory, I'd go louder. Overall I'm very happy.

 Karrowack Posted:


 irbob7 Posted:

WOW!!! It's loud and with a little modification was able to put it where the stock horn was on my 94 FXDL. It's a party favorite when you ask someone to push the horn button to see if it's working. Watch out for thrown objects and flailing arms. Hahaha

 lwilkes Posted:

I love the horn twice as loud as the stock now people can here me,

 Cecil G Posted:

An improvement on the stock horn. Posted:

Installed in 10 mins., great horn sound. Very pleased.

 Fatboy04/26 Posted:

This is a little horn with a whole lot of big sound. It's going to work really well the next time a cage cuts me off in traffic. If they can't hear the pipes, they're dang sure going the hear the horns!!

 jkirtley Posted:

It is louder than the factory horn, but I wish it was a little louder. Looks good on the bike.

 sdowell Posted:

We consider it a safety feature.

 bigd1949 Posted:

I can't wait until I can get this horn installed and go down the road with my knees in the breeze and my horn blowing at will. Thanks for the great merchandise you guys have. Merry Christmas

 momule Posted:

Installed on 07 Suzuki Burgman 650. Had to get very creative about how and where to mount but there is tons of info online in the forums about this. Works perfectly and has all through the '12 season.

 mkershner Posted:

A little bigger than described; rubs on my leg when riding. Sound is too high-pitched; sounds like Keystone Cops or bicycle horn. Metric hardware came with it. Not too confident in mounting system; just kind of hangs there. Only good thing is that it is loud!

 ghusnret Posted:

Required some mod to the OEM bracket on my 2008 HD Electra-glide but finally got it after about 3 hrs. Not using the relay as the HD dealer advised it was not needed on the bagger. So far - so good. My wife is impressed with the loudness. (Sounds like a car!) It is plastic and time will tell if the elements affect it. All in all, for the price, I would recommend it. Definately NOT plug and and play. The directions say little about installing on a bike. Have to be somewhat creative.

 tkmax Posted:

the product is exactly what i expected, now maybe these 4 wheel drivers will hear me....thanks

 kschopper50 Posted:

Would have been nice to include the fuse and terminal ends required for a motorcycle.

 danwilcox Posted:

Great product! Used the included relay, took about an hour to install and wire, had to make a brecket for it to fit in the stock place on my 05 softail but look good and sounds loud! Just in time too, riding in a torrential rainstorm and cage didn't see me at the tool booth, horn got their attention! Thanks!

 cleo44 Posted:

Replaced the Harley factory horn with this model and I am very pleased. Sounds great and easy install. Posted:

I installed this air horn on my 08 H-D Super Glide , work great I can be heard now ! J&PCycles is a great company to do business with , quick shipping , great products and prices ! Thank You J&P Cycles !

 2hogs Posted:

Pretty loud, 2x the regular Harley horn Easy to mount to replace old horn. The Chrome version looks better than the black, extra is worth it.

 felbri Posted:

very nice it took me 20 min to install and most of that was finding the proper tools and drinking coffee

 streetglide1959 Posted:

Easy to install and sounds great and it is loud.

 lmgravens Posted:

kinda cheap, sounds good

 lowend81 Posted:

Compact. Air Horn. Makes people at least double take when they start to weave into my lane XD Thanks JP!

 mrpolicy Posted:

I like the ease of install and the sound is great

 marylinda Posted:

Great horn I just love it I'd like to see anyone start to pull out of a street now. Looks cool on bike and it's LOUD

 lynesjames Posted:

I do not care for these horns - too big to easily install out of site on my Shadow 1100 and Goldwing 1500. I will buy horn style models next time. The sound is great, but the size is the real issue. I had to buy a switch, heavy wiring, and an in-line fuse for the installation, as well.

 doc693ss Posted:

Love the horn, modified a car horn bracket to attach to my bike and had to cut the supplied bolt down but it was worth the extra time to mount it, I can actually hear the horn and it does get the attention of the 4 wheel drivers, even the old ladies that want to run us over!

 Sctrash Posted:

Was having problems with stock horn on custom build. Great product, very pleased!

 ibigdddyme Posted:

This horn was easy to instal and works very well. It is very loud and I really like it. Thanks J&P for a great product.

 gpaine Posted:

Great horn, easy to install. Just need to zip-tie it on to keep it from falling off if the nut loosens while riding.

 yearslaternow Posted:

Install is not plug and play. However after an hour it works great with a little work and clean install.

 HDRider-883 Posted:

Was GREAT to get this louder than my stock horn. And it was delivwered way faster than expected.

 bearmans Posted:

On my 2009 HD bagger, there was no need to use the relay provided. Just plug and play! Only problem is the horn vibrates at 2200 RPMs. Need to figure out how to mount it so it stops. Other then that, it is LOUD!!!

 filimurz Posted:

I am very satisfied with this product. As advertised, no additonal parts were needed to attach it to my 2000 Sportster. Did have to remove the handle bars to reroute the positive and ground wires from the stock horn down to the new mounting location on the left side under the gas tank. The blast from this puppy will wake even the most oblivious cage dweller.

 Madsquirrel Posted:

WOW! This horn kicks ass! The weeny factory horn doesn't really get other drivers attention, when they're about to do something stupid. The WOLO horn will make them wake up. The installation was very easy. Nice job.

 vosevirg Posted:

Awesome horn, small fit right on the original factory horn mount but didn't come with mounting instruction so it took me a while to figure it out. FYI: put the bolt through the hole where the original horn was, tighten it down to just were you can get the this horn on and twist the horn until it is tight. Use locktit.

 freelsj2 Posted:

Plastic yuk.

 kevin1969 Posted:

Very Loud!!! Like it so far!!

 CaptainRon231 Posted:

Nice and loud, much better than the stock horn that come on the bike...

 2mean Posted:

Not nice enough to install on my Harley. But I will keep it and maybe put it on my truck under the hood where it can't be seen.Too much plastic chrome and not very good looking.

 rwilkin Posted:

Nice and loud. fits in with the contoure of my bike nicely

 jman1 Posted:

Loud but made out of plastic. Durability is a concern.

 nedholmes Posted:

Love this horn! They sit up and wake up with this horn!! Make sure to wire in the relay though, you will need it.

 Gary3014 Posted:

Not so easy to mount in factory place but wow great sound i get attention

 irbob7 Posted:

Awesome product, installed on my 94 FXDL. I wanted the loudest horn I could find and this was the ticket. Installing in the original horn location behind the rear cylinder takes some modification. Good thing I love modifying things. Drilled a new hole in original bracket and attached relay to the bracket also. Trimmed bolts from back of relay box and it fits with about 1/8" of clearance on both sides. Very snug, very loud, and very satisfied. JP ROCKS!!!

 rigotoro Posted:

Package arrived promptly. Product was easy to install and works better than I had expected.

 Dalepotter Posted:

Loud when I hooked it up right. Posted:

So far, this air horn is what I'd hoped it would sound like. Looks great on the bike, not big and was fairly easy to hook up. Note: this isn't a plug and go like mentioned. A little re-wiring and additonal material needed to hook up. Drivers defintely know you're there when you sound off.

 stealthchopper64 Posted:

Horn was simple to install,looks great, sounds great and price was very reasonable.


Great horn good to be heard Now can you hear Me drivers!

 barnabus436 Posted:

Disappointed. . I have to remove the gas tank to install. Put on bike. Not as loud as said. Would not recommend.

 trikydik101 Posted:

I ride an '03 Shadow Sabre,and I had to make a custom bracket to mount it due to its size and the location of my horn. It is NOT plug n ride for sure. There's a relay that has to be wired in. With the bracket and wiring it took about 3 hours to install... BUT, THEY WILL DEFINATELY HEAR ME NOW!! horn is an attention getter no doubt! Only a 90 day warranty, so we'll see how it holds up to riding in the FL weather. Wish I could do a RE-review in a few months.

 Eugene Dinero Posted:

It was easy to install and lives up to it's name "Bad Boy" because it is very loud and just what I wanted on my Harley. Best $60.00 I've spent in a while.

 GeneRettig Posted:

Awesome. Way loud.

 beachside Posted:

Easy to install (after reading the directions - don't toss the little piece out). Loud!! Very happy. You should see them looking for the truck...

 hangingharry Posted:


 paymanlesani Posted:

perfect for any reason

 09ultra Posted:

Good loud attention-getting blast, nice appearance. Cap to compressor compartment is loose and rattles...

 jakiboyz Posted:

Tucks away nicely in the same spot where the stock horn was. Posted:

Looks good but won't fit my bike where my horn is currently mounted. It will fit the car nicely though.

 katwik Posted:

It is awesome! I love it

 flyiingmustangs Posted:

I really like this air horn! It looks great, as attested to by several friends, and it is LOUD...just what I wanted. Although the first one received became inoperable in the frst month or so, you immediately replaced it. I am extremely pleased with the prompt attention you gave to remedy this situation. A company like yours, that is serious about providing excellent customer service, is easy to recommend to others!

 mundysue Posted:

boyfriend loves showing this off

 pita kahu Posted:

Wollo Bad Boy air horn sure makes the roos, wallabys, & straying stock incl feral pigs MOVE, sure is a lot safer riding here in Australia ran new wireing with an inline 20amp fuse straight off the battery instead of relying on the bikes original elec fuse system but still thru the bikes horn button my bike is a Kawaka 2008 VN900 classic cruiser fully recomend this horn if you wanna ride safer especially here in the bush in Australia. Cheers Pete

 jskim615 Posted:

Sound nice and loud

 xxslickxx Posted:

I removed the cow bell from mount and drilled out the top hole. Attached horn and bolted mount in original position. Looks clean sounds loud.

 keith1954 Posted:

works and sounds great.a lot better then howards horns

 mikeborghi Posted:

great product

 slindke Posted:

Simple to install, and you will be heard

 nworbse Posted:

Works great. Much louder than stock. Had to fab my own mounting bracket to fit my Hyosung GV650.

 DFJJR1944 Posted:

The sound is superior. Posted:

This horn is far louder than the factory horn.

 mark g Posted:

Love it ..if you want to be heard,get it,you will have one of the loudet horns around.

 jwb100 Posted:

Not real happy with securing mount to bike

 jlfullerton Posted:

Whoa.. I am impressed! Big Loud Horn for such a little price!!

 docsflh Posted:

No problems. Product was as described and works pefect. The airhorn installed in the same location as the OEM horn without having to make any adjustments except for the wiring and the relay. Thanks

 skeet099 Posted:

Much louder than stock. It took some creativity to mount to my 1100 classic, but it looks and sounds great.

 CBanning Posted:

Plastic chrome, no mounting bracket.

 dcarling Posted:

I have been looking for a chrome air horn that actually works and this one fit the bill. Great sound and great looks. I highly recommend it.

 davidca9 Posted:

Loves this horn. Very loud. I mounted it on my Harley Heritage Softtail Classic using the same mounting bracket that the cowbell horn cover uses. I wired it directly to the battery and hid the wires for a clean look. Great air horn at an affordable price.

 tsschnitz Posted:

Perfect horn it realy works nice and gives you an edge to attention and scare off wild life

 sonofthep Posted:

Love the horn. Looks good on the bike, sounds better then that beep beep i had at first.

 DwConrad Posted:

This is the best horn that you can buy, I paid this much for a Harley Horn from dealer and it was terrible , I love the loudness and the easy mounting. Great purchase and great product. dwc

 bigricksgl Posted:

I love the Bad Boy Airhorn, I have an 81/2 Gl1100, the only problem I had was getting a good ground and getting around Hondaline fairing, I just placed mine in the front top false tank bin, it accually helps radiate the sound! reminds me of the old bulb horn's but X20 louder!!! I wish you guys sould slip-on seat covers and continential kits! love J&P.

 jrayman Posted:

I was satisfied with it.

 alemao Posted:

Tank you for an easy pleasant transaction.Excellent Seller.

 brownonetwo Posted:

I love this horn

 DonRBrown Posted:

The horn is definitely louder than the stock horn. However mounting it on my 2005 Honda VTX1300c certainly takes more than a few minutes. I had to rewire the horn circuit in order to install the horn relay under the fuel tank. Also, the stock horn mount had to be reworked to make this one fit in the available space. After installing the horn it worked for a few days, then stopped working. I currently have a request in for an RMA to return the defective horn.

 shrek185 Posted:

Sounds great. however for my '07 1100 v-star it took a little more time to mount as it couldn't replace the factory horn in its spot

 dlanford Posted:

This is a great product. I ride a 2005 Kawasaki Vulcan Nomad. The installation took about 5 minutes. I guess the horn is about 3 times louder than the stock horn. Although I like the product and it was easy to install, I'm giving it ony 4 stars because I'll probably have to fabricate a bracket to better position the horn. The horn will mount to part of the original mounting bracket welded to the frame but the horn sits fairly far forward and xtends beyond the frame and radiator. The choke position is not an issue and shouldn't be after I fabricate a bracket. The horn comes with a 5/16 bolt for mounting but I had to drill out the mounting bracket on the bike. You have to be able to slide the bolt through the mounting hole ... there's a nut welded on the back side.

 sharky1381 Posted:

This was a vast improvement over the anemic stock horn on my new 2007 Kawasaki Vulcan 900. I am now confident other drivers will definately hear me. It is almost too loud.

 dfej Posted:

The air horn sounds LOUD, its reasurring to know that the bike can be heard, just incase they can't here my BARON'S BIG N NASTY exhaust thats attached to my 125 CI V TWIN. Another accessory purchased from J&P.

 dfej Posted:

The airhorn met my exspectations, the install was easy. The sound out of the new horn is alot louder than the OEM.

 bing34 Posted:

The product is fine. The problem installation directions and tech support. Directions say the horn can be installed in minutes with one bolt and connect two wires. (Item installed on a Harley 2004) Not true. I had to purchase extra wire, inline fuse holder and termial connectors. Lift fuel tank and move horn wires to under the set. Then wire relay and fuse holder under the seat. Installation took about two hours. The horn was installed where the bike horn was. I called for tech support and that was a waste,the guy I talked to know nothing about installing on a motorcycle. If they are going to advertise that it can be used on a motorcycle they need to give some instuction on installing. It sure can't be done with one bolt and connect two wires

 jisc39 Posted:

I like the sound of the horn, however it took a while for me to install due to limited time. The problem I discovered was that the horn did not fit properly for the 07 Honda Shadow. The horn size was to bulky even after inquiring with the (csr) giving her the bike info.

 tricac Posted:

Easy to install and sounds very loud, love it!

 aa5zrki5aa Posted:

Very loud. Replaced the stock horn using the stock bracket on my 2006 FXDI Super Glide.

 pandreasen Posted:

I love this! I did a mod to my Kawasaki Vulcan that makes it even look good! No more "meep-meep" when the cagers crowd you! Check my mods at "", bottom of page.

 aa5zrki5aa Posted:

You really get noticed with this loud horn. Really loud and fit perfectly on the Harley mounting. Plug and play.

 jmunsey Posted:

Not a bad horn. I was hoping I could still use the HD cowbell cover but it would not fit. I did not install the relay as it seems to work fine with just the button. It was not clear in the original description that a relay was needed. To improve the looks I added an HD logog medallion to brighten it up. Overall, not a bad horn
