Motorcycle Alarm System: Buyer’s Guide

It’s necessary to invest in an excellent quality alarm that will protect your bike at all times. However, the process of finding one can be overwhelming as there are options in the market. That’s why we’ve put together a buying guide to help you understand everything you need to consider before purchasing a motorcycle alarm. Take a look:


The volume of an alarm sound is measured in decibels. A good motorcycle alarm has a siren that is louder than 100 decibels. You will be able to hear for a longer distance if the sound is loud enough. Even if you don’t, it may alert the passersby, forcing the thief to flee immediately.


The alarm system should be strong and sturdy so that it can stay intact for a long period of time. Make sure it is not easy to break. It’s always a plus if it’s weatherproof and waterproof. There are a few with rust-resistance capabilities that you might want to consider buying.

Ease of use

The alarm should be user-friendly. Almost all alarms come with a remote controller that allows you to arm and disarm the device as needed. It can help in adjusting parameters, ringtone, volume, and alarm sensitivities.

Also, make sure it is easy to install because not everyone has the bandwidth or resources to visit a repair shop.

Battery life

Select an alarm system with long battery life. If you leave your bike unattended for several hours and the alarm battery does not last that long, the unit is useless. Before making a purchase, carefully read the product description and reviews. Choose alarms that use dry cell batteries that will last for months.

Sensor type

Motorcycle alarms typically include three types of sensors: motion, tilt, and shock sensors, which detect if anyone attempts to tamper with your bike. However, you must adjust the sensitivity levels, which can be done easily with the remote control. If you set the sensitivity to low, the alarm will go off as the wind blows. An alarm with a medium sensitivity setting will suffice. You can read the customer reviews to get a better idea about the product.

Additional features

The alarm units not only have a loud siren but some additional features that can better protect your motorcycle. With the push of a button, the vehicle search feature can be used to locate the bike in a crowded parking lot. The anti-hijacking feature disables the power supply, preventing the motorcycle from starting. In addition, the GPS feature can assist you in tracking down the stolen bike. The weatherproof and waterproof alarms are always something to look out for.


Motorcycle alarms are available in a variety of price ranges starting at as low as $20. However, when it comes to your motorcycle and belongings, you may want to prioritize features over price. Before making a purchase, make sure you have thoroughly researched all of your options. Also, to avoid going overboard, try to plan your budget ahead of time.

Why Do You Need a Motorcycle Alarm?

Motorcycles are a huge investment, and as they have no built-in security systems, they become an easy target for thieves. Locking the bike isn’t enough, especially when you leave it in an unsupervised parking lot and are yourself far away. This is why you need an anti-theft device for your motorcycle. An alarm will serve as a theft deterrent by emitting a loud sound that will at the very least alert passersby and startle the thief with malicious intent. No one will risk getting caught once they notice the alarm.

Then there are anti-theft locks that prevent the bike from moving by locking the disc brake. Furthermore, many alarms include GPS trackers, allowing you to easily locate where they took the bike.

The vehicle finder feature on the alarm is a savior for those who often forget where they parked their bike. With one easy click on the controller, it can be located, and you’ll be on your way in no time.

How to install the motorcycle alarm system?

Here’s how you can install a motorcycle alarm system at your home following a few simple steps:

  1. Once you buy the alarm, read its user manual instructions carefully. Prepare all the wiring.
  2. Disconnect the negative terminal of the motorcycle battery to avoid short circuits and drainage of the battery.
  3. Stick the wires of the same plug using electrical tape. Then, combine all of the small wire tapes into one large pack.
  4. Now, unlock the ignition switch to find the correct wiring that leads to the fuse box.
  5. Remove the panel where the wires are located. Make sure you don’t forget where all the screws go.
  6. Then, choose a safe location for the alarm that will not draw the thief’s attention.
  7. Use the double-sided tape, cable ties, or read the user manual to know who to secure the system to the motorcycle.
  8. Before connecting the wires to the right spots, check wire polarity. Do this by heat-shrinking or soldering the wires.
  9. When the ignition switch is turned on, the wire we need in the ignition switch harness should be 12 volts and should not have any voltage when the ignition switch is turned off.
  10.  Find the engine mobilizer wires. Split the wires that lead to the main switch of the bike in two parts. Connect one port to the first mobilizer and the second part to the second one.
  11.  Now connect the ground wires and power to the battery terminals. Wrap-around clamps or terminal taps are required here.
  12.  Test out the system to check if everything is working properly. Finally, place the panels back, and you are done.

If the instructions are too confusing for you, simply visit a repair shop or a garage nearby and get the alarm installed by a professional.

Frequently Asked Questions (FAQs)

Q. Isn’t the wheel lock enough to protect my motorcycle?

No, it isn’t. The thieves may be experts at disabling the wheel lock and will carry away your bike in a trailer/track in no time.

You can, however, install a battery tender or a toggle switch to prevent such situations.
