In this blog, we’ll explore what a motorbike disc lock is, how they work, the best way to use one to keep your motorbike safe and secure, some of the pros and cons of them and we’ll finish off with some of our top disc lock FAQs .

What is a Disc Lock?

So, let’s start by outlining what a disc lock is. A disc lock is a small, portable lock that is designed to fit over the brake disc of your motorcycle. It works by immobilizing the wheel and preventing it from turning, making it difficult for a thief to ride off with your motorbike. Disc locks are relatively inexpensive and are easy to use, making them a popular choice among motorbike owners.

Disc locks come in a variety of styles and colours and some are even alarmed such as our incredibly popular Zovii ZD10 alarmed disc lock which comes in a fluorescent green colour. The ZD10 has a built in 120dB alarm which shrieks if tampered with by a would-be thief.

How does a Disc Lock Work?

Disc locks are designed to be easy to use and highly effective at preventing theft. To use a disc lock, simply insert the locking pin through the holes in the brake disc and lock it in place with the key. Once the lock is in place, it prevents the wheel from turning, making it incredibly difficult for a single thief to ride off with your motorbike.

Disc locks are typically made of high-strength materials, such as hardened steel or titanium, to resist cutting and drilling. Some disc locks also come with additional features, such as an alarm system or a reminder cord to help prevent you from riding off with the lock still in place. Our advice would be to use a vibrantly coloured disc lock to prevent any mishaps from occurring.

The Best Way to Use a Disc Lock:

While disc locks are a highly effective way to secure your motorbike, there are a few best practices you should follow to ensure that you’re using your lock correctly and getting the most out of its security features. Here are some tips for using a disc lock:

  1. Use a high-quality disc lock:

When purchasing a disc lock, it’s important to choose a high-quality lock that is resistant to cutting, drilling, and picking. Look for locks made of hardened steel or titanium, which are strong and durable materials that can withstand a lot of wear and tear.

All of our disc locks have been independently tested and are insurance approved so you can sleep easy at night knowing you have the very best security in place. Shop here.

  1. Choose the right size lock:

Disc locks come in different sizes to fit different brake discs. Before purchasing a lock, make sure you choose the right size for your motorcycle to ensure that it fits securely and can’t be easily removed. Additionally, some motorbike disc brake pads do not have either a large enough hole in the brake disc to accept the locking pin or there is not enough space from the outer circumference of the disc to an inner hole.

  1. Use the lock every time:

To ensure that your motorbike is always secure, make it a habit to use your disc lock every time you park your bike. It only takes a few seconds to attach the lock, and it can provide a lot of peace of mind knowing that your bike is protected from theft.

  1. Use multiple locks:

While a disc lock is an effective way to secure your motorbike, it’s always a good idea to use multiple locks for added security. For example, you could use a disc lock in combination with a chain lock or a D-lock to make it even more difficult for a thief to steal your bike. Layers of security will make your bike less appealing than the one next to it.

  1. Lock it to an immovable object:

To prevent a thief from simply carrying off with your motorbike, it’s important to lock it to an immovable object, such as a lamppost or a sturdy bike rack when you’re out and about and to a ground anchor when you’re at home or securing for the night inside a garage. This makes it more difficult for a thief to steal your bike, as they would have to remove the lock and the object it’s attached to before wheeling your bike away.


  1. Don’t forget to remove the lock:

As mentioned earlier, before riding off on your motorbike, always remember to remove the disc lock. Some disc locks come with a cable reminder cord that you can attach to your handlebars to help you remember to remove the lock before riding.

So, what are the Pros and Cons of using a Disc Lock:

Advantages of Disc Locks:

One of the biggest advantages of disc locks is their portability. Disc locks are small and lightweight, making them easy to carry with you while you ride. They also don’t require any installation, making them quick and easy to use, locking and unlocking in seconds.

Another advantage of disc locks is that they are highly visible, which can be a deterrent to would-be thieves. When a thief sees a disc lock attached to a motorcycle, they may be less likely to attempt to steal it, as they know it will be difficult to remove. If your disc lock is alarmed, such as our Zovii ZD10, any tampering of the bike will trigger the alarm, scaring any thief away and alerting you in the process.

Finally, disc locks can be relatively inexpensive compared to other types of motorcycle locks, making them accessible to a wide range of motorcycle owners. Here is our Zovii ZVS14 disc lock made from high grade stainless steel and features a double locking 14mm carbide reinforced locking pin. At just £54.99 delivered, you get total peace of mind for a very reasonable price.

Limitations of Disc Locks:

While disc locks can be highly effective in preventing theft, they do have some limitations. One of the biggest limitations is that they only lock the brake disc and not the entire motorcycle. This means that a determined thief could still potentially lift the motorcycle and wheel it away into the back of a van. However, this is unlikely to happen as it requires more effort and is more visible to bystanders.

Another limitation of disc locks is that they can be easier to remove than other types of locks, especially if they are not high-quality or are not used correctly. A thief with the right tools and enough time could potentially cut or break the lock and remove it from the brake disc. Therefore, it is important to choose a high-quality disc lock and use it correctly. One counter to this would be to use an alarmed disc lock which gives a shriek as soon as the disc lock is tampered.
