Things to consider before buying Motorcycle Disc Locks [Best Buying Guide]

A motorcycle news report reveals how little action police take, despite how big an issue motorcycle theft is becoming. This only means that you have to take precautions on your own. Some users might find it challenging to find a suitable bike disc lock model.

I, therefore, did some research to help you pick the right lock. Here are the factors to consider before purchasing a disc lock. 


Consider the dimension of the motorcycle disc lock since their depths vary from bike to bike. The locking pin should be big enough to fit the diameter of the holes in your rotor. The good thing is that most brake disc locks are standard to fit all motorcycles, scooters, or bicycles.


Motorcycle disc locks are compact and small enough to take up less storage space. You can conveniently pack them in a tank bag, carrying pocket, or under the seat. They are lightweight, and bikers can carry them everywhere. Besides being highly portable makes them the best security source for the road. So look into their weight and ensure it takes up small storage space.


For more convenience, consider the overall design of a disc lock. Go for a lock that is easy to use, clean, and maintain. It is also best to pick one that has a bright color to draw both your attention and that of the thief.


High quality and durability should be your number one priority if you plan to use the device often. The material used to make the lock should be resistant to angle grinders, hammer blows, chemical attacks, and bolt croppers. It would also be best if it is weatherproof, rust-proof, and resistant to high temperatures.

Audible Alarm

Lifting the targeted bike off the ground and loading it into a van is a common technique motorbike thieves use. This is why a motion-sensitive alarm is essential. It only takes a small amount of motion to trigger a motorcycle disk lock alarm. Once it goes off, the alarm scares the thief away and notifies you about any movement near your bike.

Reminder Cable

A disc lock reminder cable ensures you don’t forget the disc lock before driving. This way, you don’t cause any damage to the motorcycle. The cord usually has a conspicuous color to make them visible from a distance. You should attach one end to the bike hand grip and the other to the disc lock.


The prices for motorcycle disc locks range depending on material quality and features. In most cases, low-quality units are less expensive and have fewer features. At the same time, high-quality ones are more expensive with advanced features. Therefore, invest in a high-quality unit if you intend to use the lock for longer. After all, if you pay more for it, you’ll want to get its money’s worth. Consider going for products with warranty guarantees if you are worried about losing money.

Frequently Asked Questions

What is a motion sensor on the disc lock?

A disc lock motion sensor is a feature that couples with an audible alarm for an additional layer of security. When the sensor detects movement and shock, it sends a signal that triggers the disc lock alarm.

Will a disc lock damage my motorcycle in any way?

Disc locks can cause damage to the motorcycle if you try to ride away when the lock is still engaged. This is why it is advisable to have a reminder cable, so you don’t forget. Another damage a disc lock can cause would be scratches on the motorcycle painting since they are made of metal. But you can buy a disc lock with rubber or nylon covers to prevent such damage.

Are disc locks better than padlocks?

Disc locks provide better security than padlocks. They are made from sturdy steel or alloy than most standard padlocks. Disc locks have a round shackle that makes them difficult to cut with any tool. Moreover, unlike padlocks, disc locks have a shielded or covered shackle with a small exposed part.

Are motorcycle disc locks effective?

Although no tool provides 100%protection, a disc lock is one of the most disputed locks for motorcycles. It immobilizes the bike by locking the wheel, making it less likely to get stolen. Going for a disc lock with a motion-sensitive alarm can be a good idea. The alarm scares away the thief and alerts you at the same time.

Where do you put a disc lock on a motorcycle?

It is best to put the disc lock on the rear wheel of the motorbike. They are generally more awkward to remove in that location. Ensure the locking pin passes through the hole in the brake disc and locks on the other side.
