Benefits of Disc Locks for Motorcycles

  • Theft prevention. A disc lock keeps a motorcycle safe and secured against theft. Although no tool or accessory can provide 100 percent protection, a disc lock is among the most reliable ones. It will immobilize the bike by locking the motorcycle wheel and making things more difficult for the thieves.
  • Portability. Unlike security chains, disc locks for motorcycles are more compact and easy to carry around. They take up less storage space and are extremely easy to use. That means bikers can bring them on rides and secure their motorcycles wherever they go.
  • Insurance. Those who have high-quality locks are likely to save money on insurance. If you get an extra layer of protection with a disc lock, some insurance companies might offer discounts on your premium. 

Types of Disc Locks for Motorcycles

Chain Lock

A chain or anchor lock is a heavy item made from stainless steel or other metals and heavy-duty materials. It attaches to the motorcycle frame or the floor. This lock type is one of the safest options out there. The heavy chains are hard to break, and the anchors stick to the ground securely. The lock, however, requires stable installation in one place, so it's not ideal for on-the-road purposes. It's also quite heavy and difficult to transport.

Brake Disc Lock

This type of mounts onto the motorcycle brake rotor and prevents wheel rotation. This way, the bike is immobilized and difficult to move. A brake disc lock is a compact device that is highly portable and easy to store, making it perfect for keeping your motorcycle safe during road trips. The only downside of this design is that bikers might forget they have an item on and injure themselves while trying to move the bike.

U-Shackle Lock

This lock type has a flat base and a shackle. It has a padlock shape. The motorcycle tire goes over the base, a shackle attaches to it, and the lock fixes the wheel. U-shackle locks are very secure, mostly because of the rigid shape that makes them hard to break. This design type also makes them more difficult to transport, although they are quite lightweight.

Grip Lock

A grip lock mounts onto the motorcycle handlebars and locks both the throttle grip and brake lever. The installation is easy and only takes a few minutes, yet the lock is very difficult to remove. With a handlebar lock installed, it’s hard to roll the bike away, although it can still be moved and lifted.

Alarm Lock

Some security locks come with built-in alarms that go off in case someone breaks them. This lock type is quite convenient because it notifies the owner about the theft, and it scares the thief away. It can be removed, but it's difficult and inconvenient. Motorcycle alarm locks are usually compact, lightweight, and easy to carry around.

Key Features


Disc locks are compact, lightweight, and therefore highly portable. They are the best option for those who need a security system when on the road, far away from the safety of their garages and heavy-duty security systems. Still, not all disc locks are the same, so look for one that meets your riding needs. Check the lock's dimensions and weight before the purchase, and make sure you can store and carry it easily. 


It's crucial to consider the overall design of a disc lock not only because of portability. For more convenience when on the road, you should pick a device that is easy to put on and take off. A disc lock should come in bright colors too, so you don't forget it's on your bike. 


Because disc locks are mostly used when on the road, they are extremely prone to damage. Without proper protection, they can't withstand rain, snow, dirt, dust, and other threats they'll be exposed to daily. That's why it's crucial to pick a disc lock with high-quality and durable materials. The lock should also have a waterproof casing and other protective features. Of course, all of this is also important because sturdier locks are more difficult to break and they become a challenge for thieves. 

Other Considerations

  • Size. Most disc locks are universal and will fit all motorcycle types. They are so versatile that they can even fit vehicles such as bicycles and scooters. It's still important to double-check the compatibility of the product with a motorcycle type. Some disc locks might be incompatible with the disc brake depth and the diameter of the holes found on certain motorcycles.
  • Audible Alarm. Consider whether you need an alarm disc lock or not. It's a useful device that will notify you about the theft as well as scare the thieves away. Keep in mind, though, that the alarm might go off without reason, triggered by random people passing by or nearby animals and objects.
  • Reminder Cable. If you try to ride away with a disc lock on, you can cause some serious damage to your motorcycle and even injure yourself. Consider getting a reminder cable if you're worried that you might forget about the disc lock. The reminder cable is a handy accessory that attaches to the motorcycle accelerator to remind you of the disc lock.

Best Disc Locks for Motorcycles Reviews & Recommendations 2021

The package also includes two stainless steel keys, which is very convenient in case you lose one. All of these features ensure more security and durability. 

Although a rather convenient item that will protect against thefts, the Kryptonite lock is not the safest option out there. It has only four of ten security ratings, so you'll probably need more layers of protection. Also, the key might get stuck in the hole, which can make unlocking the device more difficult.

Thieves will notice it and think twice about reaching for the bike, and you won't forget it's there either. The package also includes three keys, so you won't need to go to the locksmith if you lose one. 

The main drawback of this disc lock is the installation. It might be difficult to fit the pin into the drilled holes in the motorcycle disc brake rotor. Also, the key might get stuck from time to time and prevent easy unlocking, which can be frustrating and time-consuming.

Xena offers a reliable disc lock that comes with many useful features. There's an audible alarm of 120dB as well as a movement sensor. The loud alarm sound will notify you not only if someone tries to break the lock, but also if a thief comes anywhere near the motorcycle. 

The lock has a steel locking pin of 6 millimeters. It features a push-down locking mechanism and is easy to install. The device is also very durable thanks to the high-quality stainless steel. It can withstand impacts, weather threats, and more. The package includes three keys and a spare battery for some extra peace of mind. 

The biggest drawback of this product is the price. The device is pricier than other options because it features an alarm system and a movement sensor. It's not suitable for those on a limited budget. Another downside comes from the extra sensitive alarm. It might go off randomly when an animal passes by the motorcycle or when it rains. 

The Linkax Disc Brake Lock is a great option because it comes with a built-in lock shock sensor that detects vibrations and movements. It has a 110-decibel alarm and is compatible with motorcycles, mopeds, scooters, e-bikes, etc. that have up to 7mm disc brakes with holes.

It comes with a reminder cable, and its bright orange color is a visible reminder to remove the device before you start your bike. Users report that it's an effective alarm, and its compact size makes it easy to store.

However, there have been some complaints that it's not loud enough. Also, the alarm may be triggered by environmental factors, such as heavy rain and wind.

One downside is that it is extremely sensitive and will go off if it senses even the slightest vibration, which can be a bit of a hassle. Also, while the description says it's green, it's really more of a yellow color.


  • Consider the location where you're planning to keep your bike. If you need a motorbike lock for your garage, you can go with heavy-duty ones that are heavy and difficult to move. For the road, lighter versions that are easy to transport and store might be a better option. 
  • Consider getting a versatile lock that can work on different vehicles such as scooters, racing bikes, and more. Some locks can fit and protect all these vehicle types, so you can easily switch between them if you wish. 


Q: What is a motion sensor on the disc lock? 

A: A motion sensor is a useful feature that works with an audible alarm to provide more protection. The main benefit is that the sensor makes a selection of when the alarm will go off. This way, it won't be triggered by all animals or objects around it. 

Q: Will a disc lock damage my motorcycle in any way? 

A: Yes, it’s very possible. Motorcycle locks can leave scratches and dents on your bike's paintwork. They are made from metals and other sturdy materials to prevent motorcycle thefts. For that reason, they might cause some damage to the bike itself. The best motorcycle disc locks, however, come with nylon covers or rubberized parts to prevent this from happening.
