YOHOOLYO – Best Durability

This is a disc lock, featuring an alarm sound that reaches to 110 dB. It’s made entirely of metal, which makes it among the strongest and most durable options when it comes to protecting your bike.

Its locking pin measures 7mm, and you can set it up at 360°. The system comes with two keys and is suitable for motorcycles, scooters, bicycles, and any other vehicle with spokes on its wheels.

This one features a motion sensor with a 5-second delay, setting off the sound and alerting you of any shock and vibration. It’s quite durable and highly resistant to shock and physical damage. It’s also waterproof and weather-resistant.

The package includes two lock keys, an Allen key, and the Yohoolyo disc lock. It has six built-in batteries and a reminder cable, preventing you from taking off with the lock in place.



MYSBIKER – Best Waterproof

This disc brake lock is made of stainless steel and features a 14mm double-locking. It also comes with a hardened-steel locking pin and a waterproof function so that you can use it in the rain.

It’s a practical solution if you’re often parking outside as its 110 dB sound automatically activates whenever there’s vibration or shock.

The lock comes with six LR44 batteries and another six batteries to carry as a backup. On top of that, it comes with three brass security keys so that you can always access your bike even if you lose a key.

Replacing the batteries isn’t too complicated either, but make sure to check the user manual on precise instructions.

The sound will go off in case anyone tries to pop the batteries out and steal the motorcycle.



Wsdcam – Best Adjustable

This is one of the best options if you’re looking for a more innovative solution. It’s wireless and suitable for motorcycles, scooters, bicycles, cars, and even windows and doors.

It’s a vibration-triggered device that comes with remote control, making it easier to use and control from afar. On top of that, the installation process is quite simple, with a double-sided sticker or a strap.

This one has seven levels of sensitivity, allowing you to adjust it to your needs. It helps prevent the alarm from being triggered by the rain or wind. The sensitivity levels go from a gentle touch to a high impact.

Also, Wsdcam is waterproof, so you can leave it outside even when it rains.

It blasts a 113 dB sound once it’s triggered, so it’s unlikely anyone will want to temper with your bike.



Bibowa – Best Long-life Use

Bibowa is a whole set of useful items you’ll need to protect your motorcycle. This one is small but loud and virtually impossible to break. A dual-reinforced high-security disc cylinder makes it durable and suitable for long use.

Its 6mm pin fits smaller vent holes, meaning that you can use it on motorcycles and other similar vehicles. It’s waterproof and will work in the rain without any issues or rust. It’s also quite durable thanks to its rugged disc locks that are resistant to chisel attacks, sawing, and cutting.

The alarm comes with a 5ft reminder cable so that you don’t drive off with it in place.

The package comes with six pre-fitted LR44 batteries and another six batteries for backup. It also includes three brass keys.



Uolor – Best Weather-resistant

You should consider this one if you live in a rainy and windy area. Many systems are often too sensitive in such unpredictable weather, so Uolor might be your best option.

It features a 110 dB sound and movement shock sensors that activate the alarm. However, this will only happen when someone is really touching your motorcycle.

Uolor is easy to use with just a press of the button. You’ll hear a beep sound indicating that the system is active.

It comes with a 5ft bright orange reminder cable that prevents you from driving off with the lock in place. On top of that, this one comes with six internal zinc batteries and another six for backup.

It’s made of heavy-duty steel alloy body with a smooth surface. Plus, its 6nn carbide-reinforced hardened steel locking pin will prevent anyone from touching your ride.



Tchipie – Best for Theft Prevention

Tchipie has an alloy aluminum body that’s sealed against moisture, dirt, and dust. It’s suitable for a wide variety of motorcycles and bicycles.

This one has built-in sensors that detect movements and shocks, after which the 100dB sound sets off. It goes into alarm mode as soon as you lock it in, but it also has a warning triple “beep” before setting off. You have to wait thirty seconds or unlock the alarm in order to stop the loud sound.

However, this usually serves as a visual deterrent since it’s bright red. Plus, it comes with a reminder cable, so most people choose not to temper with it. It comes with six batteries already installed, and another six you should carry around as a backup.

An Allen key is included so that you can replace the batteries with ease.



Dowco – Best Security

If you need something quick and simple to use, you should check Dowco. It’s small, practical yet quite powerful and loud.

The alarm is weather-resistant and should be used on the cover of your bike. The entire installation process takes a few minutes, and you don’t even need any tools for that. You can drop it into a sewn-in pocket of the cover or your tank bag, and it will set off just as well.

This one emits 130 dB of warning and will alert you in case someone is tampering with the cover. It comes with a 9-volt battery, and it’s entirely wireless and easy to use.

Still, you can use it even if you’re not covering your bike with anything. Simply, clip the device to the wheels or any other place on the vehicle in order to protect it.



BlueFire – Best Automatic

This is quite a unique system that works on motorcycles with AC ignition. In most cases, other bikes have different ignition modes, so the wiring might not work.

It’s an automatic remote engine start that comes with a remote controller for easier use. The manufacturer recommends you have it installed by a professional if you’re not familiar with wire installation.

It comes with a shock sensor that’s adjustable so that you can control its sensitivity. Plus, it’s quite versatile, allowing you to set a warning between flashing lights and 125 dB of blasting sound.

Another great thing about this one is its anti-hijacking system that triggers an emergency alarm in case someone tries to cut off the power supply.



Gorilla – Best Compact

Gorilla is among the best options if you’re looking for a compact and easy-to-use system. It’s a small alarm, but it emits a loud 120 dB siren to alert you of any tampering.

The two-way pager it comes with receives signals from up to ½ miles away. It alerts you if someone activates the alarm.

It comes with a remote controller and three powerful sensors, including an adjustable two-stage shock sensor, internal tilt, and current sensors. The current sensor detects changes in battery voltage and blasts the sound instantly.

On top of that, Gorilla features LED warning lights, serving as a visual deterrent against any thief.

It takes less than half an hour to install this one, and the process doesn’t require any special tools.



Consumers Guide for Buying a Security System

Pin Size

Luckily, most of the alarm sets have a similar pin size. Nonetheless, it’s quite essential to consider the size and confirm that it’s going to fit before purchase.

A good pin size to go for is between 7mm to 9mm, which is what most systems have. However, some come with a pin size of 15 mm.

While it’s up to you to choose what suits you the best, keep in mind that the pin should not be short or too long. If the length doesn’t fit, it will be impossible to use it.

You should also consider its width. Make sure that the distance between the disc and walls of the lock isn’t enough to fit a saw. It shouldn’t be too tight either because it could damage the pin.

Volume or Decibels

Volume is another critical you should consider when buying a security system. It’s one of the most important aspects since it’s what’s supposed to alert you of theft.

Make sure to go for at least 100 dB because anything below that won’t be loud enough. Keep in mind that you won’t always be near the bike to hear the alarm, especially if it’s below 100 dB.

Disc Lock Reminder

Reminder cables are usually included with some of the greatest motorcycle alarms. They serve as reminders so that you don’t take off with the alarm in place.

Remote Control

The remote control isn’t necessary, but it’s quite useful if you usually park far away from where you are. It helps to control the system from a distance, especially if it sets off due to wind or another insignificant factor.

A two-way remote is usually the best choice because it notifies you when someone touches your bike. This way, you can check up on what’s happening without actually walking to the vehicle.

However, your remote should be simple and straightforward. Too many buttons will be confusing in the case of an emergency, so make sure it has no more than two buttons.


Sensors matter equally as much since they’re the ones doing the work of detecting when someone is tampering with your motorcycle. A shock sensor is the most common one that most alarms come with. This one is triggered by sudden movement and impact, like when someone kicks the vehicle.

You might also come across the current and tilt sensors. These aren’t as important, but will undoubtedly come in handy in case someone decides to touch your bike. For some added security, make sure that the system of your choice has at least two sensors.

Additional Factors to Consider Before Buying


Durability plays a significant role in how your alarm performs. You don’t want a security system that’s easy to cut off or break. It should be durable and resistant enough so that it can stand against attacks.

In most cases, durability depends on materials and the overall design. For this reason, you should make sure that the alarm of your choice is made of resistant materials.

Cheap Versus Expensive

Motorcycle alarms come at different prices, and it’s sometimes tricky to choose one because of that. Still, most experts agree that you should invest in a good security system even if it means paying a few more bucks than what you’ve planed. In any way, it’s not something you’ll have to buy as frequently.

Understanding Motorbike Alarms

Do You Need an Alarm for Your Motorcycle?

Many argue that you don’t really need an alarm if you choose a good chain or another mean of protection. And, while having a reliable chain can’t hurt, nothing is quite as efficient as a motorcycle alarm.

Having your bike stolen is among the worst thing that can happen. These vehicles cost lots of money, so why not ensure them in the best possible way?

Imagine hanging out at the mall only to find out that your motorcycle is no longer where you left it. There’s minimal chance of you ever finding it again in case someone snatches it.

Plus, alarms work as deterrents. Nobody wants to trigger a 130 dB sound and draw attention to themselves, so most thieves avoid them as it is.

For this reason, you should consider investing in one so that your bike is as secure as possible when parked outside.

Why Choose an Alarm Over Other Means of Protection?

As you may know, there are a few other means of protection, such as motorcycle locks and chains. While these might deter a thief, they usually don’t stand a chance against a more persistent and experienced person.

A motorcycle that’s parked outside and secured only with a chain is vulnerable to theft. A thief would have plenty of time to meddle with the chain, and you wouldn’t even know it’s happening.

For this reason, experienced thieves with a few tools take only a few minutes to leave with your bike even if you’ve secured it with a lock or chain.

This is the difference between these types and an alarm. An alarm system can often work as a lock as well, but it’s going to trigger a loud sound when someone touches the vehicle.

It’s difficult, if not impossible, to temper with an alarm system without triggering the sound, which is what makes it much more reliable and efficient than other means of protection.

How Does an Alarm Work?

Every motorcycle alarm serves the same purpose, which is to alert you when someone tampers with your vehicle. However, the way they perform might differ depending on their many features and specifications.

In most cases, alarms use a siren to alert that the owner. When the sensor detects movement, shock, or vibration, the system sets off a loud sound and alerts everyone. This is enough to alert the owner and scare the thief.

Some systems use a perimeter sensor, although this isn’t always the best option if you park in crowded areas. Such a system emits a loud sound when a person comes to close to your bike, entering the prescribed territory. It’s not the most reliable system since innocent people passing by might very well trigger the alarm.

Another option that some alarms come with is a GPS tracking system. It’s the most advanced out of all three, which is why it’s also the most expensive. Siren is still more popular than GPS tracking because it’s cheaper and tends to prevent thieves from acting.

GPS tracking system doesn’t emit any sound or alarm. It works in a hidden way, transmitting the location data to the owner once the bike is stolen. This allows you to notify the police of the exact whereabouts.

One drawback of this system is that it doesn’t notify you when someone steals your motorcycle. In other words, it might be hours before you notice that your vehicle is no longer where you left it. Although the GPS tracking system will let you know where the vehicle is, it might be miles away, depending on when the theft happened.

New Alarm vs. Second Hand

Buying a new alarm might sound like an expensive adventure, especially with as many second-hand options out there. However, it’s always better to go for a new system when it comes to securing your vehicle.

Nobody can say that a second-hand model won’t work or will fail, but there’s really no way to be sure. New products almost always come with a reliable warranty from the manufacturer, which is something you can rely on in case the system fails or doesn’t work.

Buying second-hand is quite risky. You might get a malfunctioning product, spending money on something you cannot make use of. Plus, someone might sell you a second-hand security system only to keep an extra key and have access to your bike when you don’t expect it.

Reliable security systems tend to be a bit pricey, but it’s much cheaper to invest in them than in buying a whole new motorcycle. Protecting your bike isn’t something you should try to save money on. For this reason, try to invest in a new product since it’s far safer than going for a second-hand one.

How To Install a Motorcycle Alarm?

Find the bike’s battery and prepare the wiring. Make sure to disconnect the negative terminal to prevent battery drain and electrical shorts.

Take the wires of the same plug and twist them together before taping them with electrical tape. Tape them all together and find those that you’ll connect on the vehicle.

Most of the wires run from the ignition back toward the center to the fuse box. Open the ignition switch so that you can test the wires.

However, don’t connect anything near the ignition. Instead, follow the wire back, closer to the alarm system. Remove the panels where your cables are, but make sure to remember where all the clips and screws go.

Find a spot where you’ll install the system, but try to pick the one that’s not as visible. Glue or strap the system to a flat surface, but make sure to prepare it first. If you use glue, you have to clean the surface thoroughly with some rubbing alcohol.

Go on to test wire polarity and connect the wires to the right locations. You can do this by soldering or using electrical tape again.

Find the immobilizer wires and cut the side of the one that leads to the main power. Connect it to the immobilizer wires on both sides. Connect the ground and power wires to the battery terminals.

Frequently Asked Questions

Are there motorcycle alarm systems with GPS?

As we mentioned, some motorcycle alarms come with a GPS tracker. This allows you to know the exact location of your vehicle in case someone steals it.

However, these alarms usually don’t emit any loud sounds to notify you that someone is tampering with the vehicle. Some models might inform you within the iPhone and Android apps provided by the manufacturers.

The best systems allow you to check up on your motorcycle at any time. In most cases, these are highly adjustable, featuring a wide range of features.


Securing your motorcycle should be one of your top priorities, especially if you live in a theft-prone area. Sometimes, an exposed bike is tempting even to people who didn’t think about stealing it.

For this reason, choosing a reliable motorcycle alarm system ensures that your vehicle is safer than ever. It often acts as a deterrent so that even the most experienced thieves don’t want to bother tempering with it.
