A motorcycle chain lock is a good way to safeguard your motorcycle against theft, but what’s better is adapting one with an alarm system that scares opportunistic thieves away and attracts public attention to the source of the problem. If you are a motorcycle owner and want to protect your valuable possession, consider purchasing one of the best motorcycle alarm systems featured in our buying guide below. 

These locks clamp onto the holes in the motorcycle disc brake and immobilize the bike. They are compact and heavier than handlebar grips or ordinary chain locks. Just be careful not to ride your bike with the disc brake on or you may fall off and damage your bike. Some models come with a reminder cable, which typically runs from the lock to the accelerator and reminds you to remove the lock before you ride away.

Handlebar grip alarm locks can be fitted on either the left or right side of the handlebars and prevent you from riding away. These locks grip onto the front brake and throttle on one side and grip the clutch on the other side to prevent the bike from being put into gear. They are also constructed with tough material and cannot be cut through easily. The built-in alarm system delivers a powerful siren of 100 decibels and above.

Pyle is a renowned equipment manufacturer based in the United States. It was founded in 1960 exclusively as an audio equipment manufacturer, but the company ventured into the production of health and fitness equipment, car audio equipment, office tools, musical instruments, and outdoor gadgets later in the 2000s. Pyle products never compromise on quality, so consider purchasing the Pyle Watch Dog Bike Alarm if you want to try out one of its top-notch security systems. 

From its headquarters in Los Angeles, California, Gorilla Automotive manufactures and designs some of the best automotive products aimed at making every car owner's life better and more comfortable. Gorilla specializes in a wide line of products, including wheel locks, automotive tools and gauges, lug nuts, replacement keys, and security alarms. One of its best-rated products is the Gorilla Automotive Motorcycle Alarm.

An alarm’s power and volume is measured in decibels, which tells you how loud the alarm can be. What type you choose will largely depend on where you park your bike. For instance, if you plan on parking outside loud establishments or leaving it parked at a large distance from where you’ll be located, then you need an alarm system with a high decibel rating. Anything over 150 decibels will do. Anything below that will deliver a lower sound level.

It’s just not enough to have a loud alarm system. You also need something that’s strong enough to latch onto your bike in case the alarm is cut off. The material should be made of durable and weather-proof stainless steel or any other hardened metal that will stay intact no matter how hard the thief tries to saw through it.

The Mysbiker alarm lock is a highly functional alarm system with a 110-decibel alarm, which actively senses any vibrations or shock and protects your bike from potential theft. The unit is designed with water-resistant, forged stainless steel and a carbide-reinforced hardened steel locking pin that’s difficult to saw off. You can easily attach the locking pin to the lock with one hand, and it automatically activates itself once secured in place.

This disc alarm also includes a six-foot disc lock reminder cable, which attaches to the brake or clutch lever and reminds you to remove the lock before riding. The alarm system runs on long-lasting LR44 batteries that offer a long life of reliable performance, and the locking mechanism makes a loud beep once the alarm is activated. The lock is compatible with most motorcycle models, including Yamaha, Suzuki, Honda, and Kawasaki.

A major drawback of this alarm system is that it’s heavy and may damage your bike if you ever forget to unlock it before riding off. Some units may come with a design flaw where you may turn off the alarm by unlocking the unit, but the alarm may start to go off again as soon as you relock it. Also, the alarm has a low volume, which can easily be muffled with a wet towel, and it may not work in cold temperatures.

The Wsdcam is a vibrational-triggered alarm system with seven sensitivity levels from a gentle touch to a hard push. It also includes a search bell that lets you find your bike if you forget where you parked it. The alarm is reinforced with an IP55 waterproof PC material shell and includes a double-sided sticker for easy attachment on the bike. It uses 3AA alkaline batteries, and the remote control uses 12V/12A alkaline batteries. The unit can be operated with a wireless remote at a range of 30 to 40 feet and can use up to eight remotes.

Its 113-decibel alarm system allows you to change the ringtone to suit your preference. It also includes an SOS function that allows you to call for help in case the battery tilts by more than 45 degrees. The alarm kit comes with batteries for the alarm and remote, plus it includes a low-battery indicator that alerts you when it’s time to change the battery. It’s ideal for use on electric bikes and motorcycles as well as doors and windows.

One drawback with this model is that it comes with unclear instructions on how to activate the keyless alarm system. It also gives a click warning when it senses motion, which may give someone tampering with the unit enough time to muffle and deactivate it before it alerts anyone. Moreover, you cannot disarm the alarm without the remote control. 

This anti-theft, motorcycle security alarm system is strong and durable. It’s also waterproof and doesn’t rust even when left outside during a heavy downpour. The unit features a quarter-inch pin diameter that fits small vent holes and a 110-decibel alarm. The disc lock is well-protected with a high-security, anti-drill lock core and will sound an alarm if the key doesn’t match. It will only stop making noise once the right key is inserted. It’s also resistant to cutting, chisel attacks, and sawing.

The alarm kit comes pre-fitted with six LR44 batteries and also includes six extra batteries and three brass security keys. It contains a bright-colored, five-foot reminder cable that will remind you to remove the alarm clock when you want to go for a ride. Overall, it’s a small-size lock with a loud volume and is suitable for scooters, choppers, sports bikes, cruisers, racing bikes, and most other motorcycles.

However, there are some manufacturing and design flaws with this alarm system. First, the alarm is highly motion sensitive and may go off even if someone walks too closely near your bike. Also, the battery compartment isn’t waterproof, and you may have to reinforce it with tape to protect the batteries from a heavy downpour. This lock may not fit on some Yamaha models.

A: Not really. If there are three to four people with a trailer they may manage to pick it up and disable the alarm before it goes off. The only way to outsmart them is to get a GPS motorcycle alarm lock with a motion sensor and a loud ringing volume with anything over 100 decibels. It will alert the people nearby when the motorcycle is lifted off the ground. Also, bike thieves tend to avoid bikes with advanced security systems and a motorcycle lock that anchors the bike to the ground.

A: It depends on the quality of the device. Some units are made with hardened stainless steel that resists damage by rust and water. The unit also protects the built-in alarm system from weather and environmental elements that may damage the system. You need a higher-end model if you plan on riding in winter as a cheap model may freeze up and the alarm won’t work.

A: Your bike has two discs, so it is possible to attach an alarm on the front and rear disc for optimal security. You could also use disc locks from different brands to test how effective each one is before you settle on a brand. However, ensure that each disc lock has a reminder cable in case you forget to unlock one of the disc locks. 

If you want a durable, waterproof alarm lock system that’s suitable for a wide range of applications and keeps your motorcycle safe, then consider the Mysbiker Alarm Lock. It will work on rainy days and reminds you to remove the lock to prevent potential damage to your bike.
