Best Motorcycle Alarms Buying Guide

line of motorcycles

At this point, you hopefully have a general idea of the motorcycle alarm you want for your bike.If not, we put together this helpful buying guide to make the buying process easier for you.

Here are some of the different features to consider when you’re shopping for a motorcycle alarm. If you still have any questions, don’t hesitate to let us know in the comments.


One of the most important features of any motorcycle alarm system is the durability of the system itself. There’s no point investing in a cheap motorcycle alarm that isn’t going to do its job.

The problem with cheap alarms is that they’re easy to deactivate and break into. This means you’ll walk back and find your bike missing with the cheap alarm sitting on the ground where your bike was.

Instead, it’s worth investing in the best motorcycle alarm system that you can afford. This will help give you the peace of mind necessary when your bike is parked out of sight for an extended period.

Look for alarms made using durable materials, such as steel and aluminum. Don’t forget to check reviews to see what people have to say about the durability.

Alarm Volume

Another factor to consider with any motorbike alarm is the volume of the alarm itself. If the alarm isn’t loud enough, it won’t draw attention to the person trying to steal your bike.

When it comes to choosing the right alarm volume, look for options with a volume of at least 100dB. Anything less than this would be pointless and not nearly effective enough at keeping your bike secure.

The louder the better because you want to draw attention to the activated alarm system and deter someone from taking your motorcycle. Having a louder alarm is also more likely to notify you, especially if you’re within earshot.

Locking Mechanism Pin Height

While not the most important factor, the pin height of the locking mechanism used to be considered. Standard pins range in size between 7 and 9mm, with a longer pin being a better choice.

If the pin isn’t long enough, it’s going to have difficulty fitting on to the disc. With a pin that’s too long, this could provide space for someone to saw through it and break the alarm off.

Look for alarms with a space between the lock walls and the disc that allow enough room for the alarm to be closed, but not enough room for someone to use a tool. Anything in the 7mm to 10mm range should be sufficient at properly securing your bike.

Reminder Cord

It’s important to use a reminder cord with any alarm that connects to your disc brakes. Without one, it’s possible to forget that the lock is equipped and you could unknowingly ride off.

When this happens, your bike will sustain serious and expensive damage. That’s why it’s a good idea to always use a reminder cord whenever you’re locking your bike with an alarm.

Price vs Value

Many riders will look at the price of a product before considering the value. When it comes to motorcycle alarms, it’s important to consider the value first.

It’s better to invest more in a valuable locking system that will protect your bike. Investing in a lower quality system could result in your motorcycle getting stolen, which is definitely poor value.

As always, don’t forget to check out reviews and see what other people have to say. This would give you the best idea on making the right choice with your price vs value comparison.

Motorcycle Insurance Claim

Depending on where you live, your insurance company might require that your scooter or motorcycle have a security system. Without a security system, it’s a lot easier to steal a motorcycle, this makes it more of an insurance liability.

When shopping for alarm systems, look for products that fulfill the insurability requirements. These typically have a stamp or marking on the box that let you know they’re suitable for insurance purposes.

Wiring vs Freestanding

Most motorcycle security systems are freestanding. This means they don’t have any wiring or cords for them to work effectively.

On the other hand, some of the best motorcycle alarms are wired directly to the motorcycle battery. This provides an additional level of security and makes the bike even harder to steal.

Choosing a specific type ultimately depends on your personal preferences and budget. Should you go with a wired motorcycle alarm, these tend to be more expensive, although they’re relatively easy to install.

Wired alarms are ideal if you’re parking your motorcycle in high traffic and high crime areas. Otherwise, a disc lock setup it’s just as easy to use while providing a suitable level of security.

Alarm Sensitivity

The last feature to consider is the sensitivity of the alarm itself. It’s a good idea to choose one with adjustable sensitivity.

This way you can adjust the sensitivity depending on the conditions around where the bike is being parked or stored. In some cases, rumbling trucks or traffic can set off the alarm, something you don’t want happening on a regular basis.

It’s also possible that having an alarm that’s too sensitive would set it off frequently. If you live somewhere with a lot of people around, such as an apartment complex, this could be annoying to your neighbours.

It’s important to consider the sensitivity of the alarm and the environment that you live in when you’re looking at the alarm sensitivity. Check the product specifications or manufacturer description for more information about sensitivity settings.

Motorcycle Alarm Terminology

Here are a few definitions for some of the terms you may have come across during your search for the best motorcycle alarm systems:

dB – This stands for decibel. Decibels are how sound levels are measured.

Disc Brake – This is the metal disc around your brakes on the motorcycle wheels. Many locks can be attached to the disc brake, making it impossible to move the bike unless the lock is removed.

Why Buy A Motorcycle Alarm?

Loading your bike into a van is the easiest way someone can steal it. Depending on the bike, it’s possible for just one person to accomplish this.

With a motorcycle alarm, any movement or vibration can trigger the siren. This would alert you of what’s happening if you’re within earshot. It would also deter a would-be thief from making off with your bike.

Some motorcycle alarm systems even come with GPS trackers. This is a great feature to have as you could track your bike if it happens to get stolen.

Theft Prevention

Another reason to use a motorcycle alarm is for theft prevention. Some motorcycles, especially higher-end sport bikes and cruisers, are popular targets for thieves.

Can You Use More Than One Disc-Lock At a Time?

Yes, it’s a good idea to use more than one alarm if you live in a high-crime and high traffic area. This provides double the security and makes your motorcycle that much more difficult to steal.

When using two lock alarms, use one at the front as well as the back of your bike. Check out our post on the best motorcycle locks for some alternatives. You could even chain them together for yet another level of security.

Where Should You Attach the Alarm To?

Depending on the alarm system you have, attach it to either the disc brake on the rear wheel or somewhere underneath the frame. Anywhere that keeps the system away from water and the weather elements is a great spot.
