Kuryakyn 2720 MTX Road Thunder Review

On a long road trip, having music together with that sweet engine sound is a great deal and can lift the mood. If you have a loud bike, installing speakers in it is not enough. It must have sufficient volume to stand out and not get overwhelmed by the engine, especially at high speeds.

For all bikes loud, or average, big, or just right, to get to your destination every day, the best option to give you your favorite tune from your favorite music playlist is to have a loud and clear speaker system. With this setup, you can combine that revving engine sound with that grooving and popping speaker sound.

This post is our honest review on Kuryakyn 2720 MTX Road Thunder. We will try to share everything you need to know about this motorcycle speaker and why it is one of the popular soundbars on the market suitable for your bikes today.

The Style

Kuryakyn 2720 MTX Road Thunder is a soundbar designed for motorcycle handlebars. The soundbar is a loudspeaker that provides audio from a wide enclosure. It is long and usually positioned horizontally to make it easier to mount above or below display devices such as smart TVs, monitors, etc. It has small, almost, as big as tweeters speakers inside. Each or some speakers have different roles: low, mid, or high.

It has a built-in heat sink and self-protection circuit to resist excessive heat and over or under voltage regulation. This motorcycle speaker is meant for handlebars and expects it to perform well in that area.


Full-range speakers

Don’t judge its small speakers because they are not the typical speakers that are separate and have their amplifiers or those passive speakers dependent on external amplifiers.

Its speakers are full-range which means it provides an audible frequency range most of the time or normally. Apart from that, it also has dual voice coils. Speaker measures 10.6 “L x 2.9”, and the bracket is 6 “L x 3”

Speaking of frequency, it has four high-frequency 1 “silk dome tweeters with N42 grade magnets for powerful distortion-free at any volume level.



The wattage determines how powerful this motorcycle soundbar is. The Kuryakyn 2720 MTX Road Thunder has 300-watt peak power and 1.0 amp with increased versatility due to its integrated USB charging port.

When we say peak power, it refers to the maximum power level that the speaker can handle in utilizing short bursts. Let us give you an example, the speaker with a 30 watts RMS rating may confuse us if it has a power rating of 60 watts. The 30 watts then 60 watts? What is that supposed to mean? Meaning, the speaker is more comfortable running 30 watts of continuous power and sometimes bursts to reach 60 watts.


Sources of input

Similar to the new motorcycle speakers now on the market, the Kuryakyn 2720 MTX Road Thunder has a 4.1 Bluetooth receiver for Bluetooth-enabled devices. It allows you to easily stream your favorite music from popular audio streaming platforms using your smartphone.

If you want the traditional or classic way of listening to your audio with wire, it has Auxiliary input and output ports. You can connect standard devices via a 3.5 mm cable. So depending on your taste, maybe mood, or available source device, you can switch connecting to it wirelessly or with wires.


Weather resistance

For outdoor dwellers like our bike, any speaker system we put in it should not only be waterproof but can also withstand a variety of weather conditions. The Kuryakyn 2720 MTX Road Thunder is durable and has IP66 rated weather-resistant housing. It also has a built-in heat sink and self-protection circuit to combat excessive heat and over/under voltage regulation. Weather resistance means that the electrical device is designed to withstand light exposure to elements that can affect or damage a device, such as sunlight, rain, and wind.


IP Rating

To give you some idea of what IP66 is, let’s start with the IP (Protection or International Protection). It is a standard that specifies the level of sealing effectiveness of electrical enclosures against the intrusion of external elements such as moisture, dirt, water, or tools.

As mentioned, the Kuryakyn 2720 MTX Road Thunder has IP66 rated housing. Now, what does 66 stand for? First, let’s break them into two digits. The first digit refers to its solidity. It indicates the level of protection provided by the enclosure against foreign objects such as fingers or tools that can cause serious injury when there is direct contact with electrical conductors or moving parts. Also, it includes dust that can damage its circuitry. The second digit refers to the water protection of the equipment inside the enclosure against drips, submersion, sprays, and so on.

There is a reference chart to determine the digit beside the IP rating, like in this case, IP66. We will discuss IP rating in the future so let’s go into further details there. For now, let’s determine what the digits 6 and 6 mean in IP66. The first digit six indicates that the device “totally” protected against dust. The second digit five ​​means protected against “strong” pressure occurrence of sudden discharge of water from all directions with limited ingress permitted.


About mounting

This motorcycle soundbar speaker system is designed for the handlebar. It has universal articulating mounting clamps that fit virtually any bars between 7/8 “and 1 – 1/2”, remember brackets are patent pending. It is also easy to install, and no complicated setup is needed. However, you can also try to install it anywhere you want as long as it can fit well. But we suggest that you mount to where it is designed for.


Sound quality

This soundbar speaker system has an internal 4-channel amp powers two 2 “x 3” full-range speakers with dual voice coils and four high-frequency 1 “silk dome tweeters with N42 grade magnets for powerful distortion-free sound at any volume level. Common or by default soundbar has a built-in amplifier because that’s where it’s speakers get full performance. Its amplifier is 4 x 19 watts RMS and max 4 x 23 watts.


You can get this soundbar motorcycle speaker brand new on Amazon for $ 404.99. Considering its quality, built, and simplicity, the price is fitting and worth the try.


All about the numbers

Bear with us because it is too technical. For users with extensive knowledge of electrical and speakers, this is as simple as ABC to understand. For most users, in the future, we will post articles discussing all technical terms you will encounter in dealing with motorcycle speakers.

Honest response

If you are often on the highway and riding at high speed, this is not much for you. If in town, this motorcycle speaker is good. So volume will be affected a lot at higher speeds unless you know you’re playing you will not be able to hear it. For example, if you are using an 800cc cruiser with aftermarket pipes wear a half helmet at 70 mph, it is not advisable to play it on the highway. If you use its radio while riding on either the freeway or town, there is a big possibility that you will not hear it.

It does not have too much bass but loud enough while riding with the V star 1100 with stock pipes. But it can be overwhelmed by aftermarket louder pipes.

This soundbar motorcycle speaker system is small for big bikes, but it is in line with its purpose. It is easy to install, especially if you have general mechanical skills. If you have a stryker, you will need a few modifications for it to fit.

It also drains the battery quickly when you connect the ignition’s white wire to the battery terminal. When the radio is turned off, it should not be able to drain the battery too much. In this case, yes, it consumes energy from the battery. Probably it has something to do with its design. Ideally, the radio displays time in stand-by mode and has a DIM sensor to increase automatically or decrease LED display depending on sunlight exposure.

It would be better if the end pegs connecting the hand bar using the clamps were rotated by +-30 degrees because it is difficult when the position where the speaker and display are mounted cannot be adjusted.

As a question, it is better if << | >> and the volume +- buttons are circular rings on both sides of the speakers so you can rotate them if you want to change the song and volume similar to the menu rings found in BMW. It is also better if there is a shuffle, repeat one, and repeat all buttons. Also, it would be best if there is a usual EQ option for low, mid, and high adjustments. The << and >> buttons to turn the volume up or down are a bit confusing while on the ride.

Its Bluetooth is easy to connect and will connect immediately at startup. The radio has a good antenna and captures all the stations, but it’s hard to tune or set presets.

When it comes to its clamps, it has a bit of an issue because for other users though it is 1″, it is still a bit loose. Its unit will be affected due to the vibration that can slide it down and interfere with steering. You get thin rubber strips for even more “grip” under the clamp.

The unit includes four wires: red for power, black for ground, orange for ignition or turn on and blue for another amplifier if needed. The power and ground have connectors that slide under the battery terminal screws. The orange wire is tied to the tail light. Approximately it takes 25 minutes. This soundbar is made entirely of aluminum. Be careful with the clamps around the unit, once you have tightened it, it will usually bend the mesh on the speaker, and you will be forced to crush the tweeters slightly.

When you install it on the 2017 HD TKS with a factory 47 1.5 “handlebars, you will need a 1.5” light bar clamp because the kit will only take 1.25 “.

Overall the unit is loud, but it is not that loud. With a windshield, you can get a boost in volume. Wearing a helmet and listening to it at a speed of up to 60 mph, you will notice that the sound will diminish. You will no longer hear it clearly because the engine will be going to overwhelm it.


Additional information

  • It has a 1-year warranty handled through your original place of purchase.
  • 150 and 300-watt soundbars can be linked together.
  • The orange wire will need to be connected to a 12 volt keyed power source. There should be an orange wire on your OEM wire harness that should supply the necessary power required. This can be verified with a 12-volt test light or voltmeter.
  • There are now 1 1/2 “clamps in kits after 8/15, if your kit does not include the 1 1/2 clamps they are available to purchase at Kuryakyn as a component part.

  • There are two fuses. One in the ignition circuit and the other in the battery circuit. Make sure you put the right fuse in the right fuse holder.
  • Bass does not travel well through the air from something like this. The only way to really get low-end would be to install some type of sub into a tour pack or saddlebags.

Our take on Kuryakyn 2720 MTX Road Thunder

There you have it. I guess we exhausted all the information needed to describe and say something about this motorcycle soundbar from Kuryakyn. For us, this unit is pretty decent enough to do its job. Its volume is not that enough especially for louder bikes however if you use a windshield there will be a big difference and boost in volume. It is not really a boost in volume but the windshield will help so that the wind does not affect the sound too much and can concentrate the direction of the sound towards you while riding.
