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

While motorcycle theft is a growing crime, police and law enforcement agencies often have limited options available once a bike has been stolen. For this reason, it is a good idea to take preemptive measures to prevent motorcycle theft from occurring. Using a disc lock is an excellent measure to take, however with so many models to choose from, deciding on the best lock for you can be difficult. 

Even though each situation may differ, there are some features that should be considered when looking into any disc lock. Keeping these things in mind when shopping for the best lock for you will help make sure that you are able to find the best option for your specific needs. 


Considering the dimensions of your motorcycle discs as well as those of the lock itself is the first step in knowing whether the lock you are looking at will be compatible with your bike. Checking the depth of the brake holes from the outside of the disc, as well as the diameter of the holes, will ensure that you know the maximum width of the locking pin. 

In most cases, motorcycle locks are meant to fit a wide variety of different bikes. However, it is still a good idea to check the size and placement of the locking pin just to be sure of the lock’s compatibility with your motorcycle’s brake discs. 


As a tool that you will be carrying with you from place to place, it is a good idea to ensure that the lock you choose is easy and convenient to carry. Be sure that the lock that you choose can easily fit in a tank bag, or be attached to the bike using a clip. Many of the more popular disc locks on the market may have optional attachments that make transporting them more convenient. 


When considering the design of your chosen disc lock, you may want to consider a lock that is highly visible. This ensures that any potential thief can see the lock, which can often keep them from making an attempt to steal your bike. This can also have the benefit of reminding you that the lock is in place before taking off for your next destination. 

Other things to consider when it comes to the lock’s design include how easy the lock is to attach, and how easily it can be maintained when necessary. This may include changing batteries for disc locks that feature alarms or motion detectors. 


Choosing a motorcycle security lock that is made with high quality, durable materials is especially important for a lock’s ability to handle attacks from the various tools commonly used in motorcycle theft. High quality steel is a very resilient material and does not easily deform when subject to pressure. Better materials will also be resistant to sawing tools and chemical attack, as well as rust and weather. 

Audible Alarm

A motion-sensitive alarm is a great way to ensure that you are aware if anyone is tampering with your motorcycle. This is especially useful, as a common method for stealing motorcycles is to lift them off of the ground and into a truck. Simple mechanical disc locks can do nothing to prevent this, however a motion sensitive alarm will produce an audible signal to let you and everyone in the surrounding area be aware that something is being done to the motorcycle. 

Reminder Cable

A disc lock reminder cable provides a visual reminder that the lock is attached, ensuring that you don’t attempt to ride off with the lock in place and damage your bike. Typically a reminder cable will be a highly visible color, allowing it to be seen from a distance. These cables also usually attach to the handlebars, making them nearly impossible not to notice. An added benefit is that prospective motorcycle thieves will see that a lock is in use, and choose not to tamper with the bike. 


Deciding how much to spend on your motorcycle disc lock may come down to factors such as how frequently you will be using the lock, as well as the areas you typically park in, and even how long you intend to use the lock. Higher priced units will usually be made from higher quality materials, have more features to provide a higher level of motorcycle security, and even have gone through more testing to ensure their quality. 

The lower the cost of the motorcycle disc lock, the fewer features it is likely to have, with some disc locks even compromising on the quality of the lock itself in order to achieve a lower price point. When factoring in the cost of your disc lock, consider how likely it is that the advanced features or build quality will come into play. 

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 to alert you to any tampering with your motorcycle. If the sensor detects motion or shock it will set off an alarm that draws attention to the bike. This provides an extra layer of motorcycle security and lets you react to any tampering. 

Will a disc lock damage my motorcycle in any way?

A disc lock can damage a motorcycle if you attempt to ride away while it is still engaged. It is a good idea to have a reminder cable on your lock to ensure that you are always aware when the lock is in use. 

Are disc locks better than padlocks?

Disc locks are much better at securing your motorcycle than padlocks. The locking pin on most disc locks features a very small exposed segment that is very difficult to get at with tools or cutting implements which might make short work of a simple padlock. Additionally a simple padlock will not have the sort of features, such as alarms and motion sensors, that are commonly available on disc locks. 

Are motorcycle disc locks effective?

While there is no 100% effective method for preventing motorcycle theft, motorcycle disc locks provide excellent security, and make it significantly harder for a potential thief to steal a motorcycle. Disc locks lock the wheel of the bike, preventing it from easily moving, and many disc locks include motion sensors and audible alarms that draw attention to the bike, scaring thieves away and alerting you at the same time. 

Where do you put a disc lock on a motorcycle?

Disc locks attach to the brake discs of a motorcycle in order to prevent the wheel from moving. While a disc lock can attach to either wheel, it will generally be more awkward to remove them from the rear discs, making the back side of the bike an ideal location to attach a disc lock. 

Final Thoughts

Investing in a motorcycle disc lock is an effective way to deter potential thieves and provide extra peace of mind. While it may be difficult to sort through all of the different options available on the market, we have outlined some of the most critical things to consider when looking for the best option for you and your motorcycle.
