1. XENA Motorcycle Disc Lock

XENA Motorcycle Disc Lock

You might remember this disc lock from our list of the best motorcycle alarms. It rightfully opens our list as one of the best disc locks you can get.

This reliable disc lock comes with a handful of features that will prove useful for your bike. Firstly, you’ll love the audible alarm it emits. Its alarm can go up to 120 dB which is a great enough level to trigger the surroundings.

The Xena disc lock also comes with a movement sensor. That means that the alarm will go off if it detects any unusual movement from the bike. This will help deter thieves even before they could try to break the lock.

Xena equipped this lock with a steel locking pin that measures 6 mm. It also comes with a push-down locking mechanism. Such a feature makes it incredibly easy to install.


Made from high-quality stainless steel, you’re sure that it’s a durable lock in general. It can withstand impacts as well as environmental factors such as the weather.

However, with the quality of this lock, expect it to be a tad pricier than others on the list. Not all alarms come with a movement sensor and that’s a technology that costs a lot, especially for alarms.

That said, this is a powerful alarm and it could be a little too sensitive at times. It can go off even with little movement from its environment such as when an animal passes by. Even rain can affect the sensitivity of the alarm. Included in the package are three keys as well as a spare battery so you never worry about it ceasing to work.

The feature makes for a great one especially if you’re constantly on the go. Plus, with a 100-decibel alarm, you will probably get in trouble if it goes off on the road.


It also comes with a 3D detection system. This means that it detects just about any movement around the bike. For instance, it would recognize vertical lifts if your bike gets lifted instead of dragged. The detection system will sound the alarm once triggered.

If you forget about the disc lock, you shouldn’t worry about it going off randomly. It has an accidental ride-off attempt. It will beep multiple times to give you enough time to disarm it. If not, the alarm will go off.

The only downside is that it’s pretty heavy at around 2.64 pounds (1.2 kg). However, with such sturdy construction, this makes complete sense. Plus, it’s small enough to fit under your seat.

Best Motorcycle Disc Lock Guide & FAQs

Benefits of Motorcycle Disc Lock

Easily, the benefit of having a disc lock is that it prevents theft of any kind. It also provides an added layer of security in case you already have a set motorcycle security system. It’s a great way to keep the bike immobile when not in use. So, thieves won’t get away with your bike easily.

It’s also very portable. Compared to other motorcycle security systems, this is a quicker fix for theft protection. You can store it anywhere when not in use and even bring them wherever you want to.

Moreover, disc locks will help a lot if you’re applying for insurance. You’re more likely to save money because companies often offer discounts if they find any security measures on your bike.

Types of Motorcycle Disc Lock

Chain Lock

A chain lock is almost often called an anchor as well. With that, it’s understandably heavy. Typically made from stainless steel, it’s a heavy-duty lock that will keep your bike from being moved.

The way it works is that it attaches safely to the motorcycle’s frame or right to the floor. As an anchor, it sticks right to the ground and the chains make it hard to break.

However, it’s not ideal for people who are always on the go. It’s great for bikes that aren’t moved as often. This type of lock is also incredibly heavy so it will be hard to transport it.

Brake Disc Lock

This is one of the most common disc locks as you can see on our list. It mounts directly on the motorcycle’s brake rotor. This effectively prevents the wheel from being moved.

A brake disc lock will keep the bike from being transported by being rolled away. It’s also very compact so you can carry it anywhere and store it even in small spaces. People on the go prefer this due to its compact design.

However, since they are small, many bikers forget it exists so they end up forgetting they’re ever on. This sets off the alarm and causes inconvenience. It can also cause bodily harm when the rider attempts to ride off with the alarm engaged.

Luckily, some are packaged with reminder cables to tell you that the disc lock is engaged.

U-Shackle Lock

You might find a disc lock that looks a lot like a padlock. They do exist and they’re called U-Shackle locks. They’re also very secure and incredibly rigid. It won’t succumb to your typical lock-breaking tools.

However, they’re bigger than your usual disc locks so they’re not as easy to transport. They are, however, very lightweight. That said, you might also forget they’re on.

What to Consider When Buying Motorcycle Disc Lock


You would want a motorcycle disc lock that can handle just about anything it goes up against. We’re talking impacts from lock-breaking tools as well as weather elements.

Disc locks typically have stainless steel construction so they don’t rust and they’re typically waterproof if not weatherproof. They usually work despite being exposed to rain, snow, or dust.

Find a lock that has durable materials and won’t break easily. They should be sturdy enough that thieves won’t easily break through them.


The great thing about disc locks is that they’re incredibly portable. It helps you bring something to secure your bike especially if you’re constantly on the go.

A disc lock must always be lightweight and easy to carry anywhere. That said, that shouldn’t affect the sturdiness of your lock. Just because it’s portable doesn’t mean it should easily break when tested.

Always check the weight and dimensions of your disc lock before making a purchase. This leads us to the next consideration.


While you can expect most disc locks to fit a variety of motorcycle types, it’s always best to get the dimensions of the lock. They’re incredibly versatile but different locks have different pin dimensions.

Check the radius of the drilled holes on your wheel to know if the disc lock you’re eyeing will fit it. You should also check the depth of your disc brake because it might not be able to accommodate the lock.


By design, we’re talking about the overall quality of the lock. You should pick a lock that’s easy to engage and disengage. In the same effect, you should be able to put it on easily as quickly as you take it off.

A disc lock with a bright color is also a great idea to remind you that it’s there. However, you can always choose one that fits your bike’s aesthetic if you prefer.

Reminder Cable

A reminder cable should be included if possible. Many people forget that they have disc locks on and it can only lead to one of two things, sometimes both.

Firstly, it could cause accidental firing of the alarm. You don’t want more than 100 dB of the noise blaring on your ear, right? Plus, it could cause you serious bodily harm. If you attempt to move your bike and it resists, you could fall and injure yourself.

Audible Alarm

Not all disc locks have alarms but having one is a great way to deter thieves. It will scare them away once set off but it could also be a pain especially if your lock has sensitive sensors. Any disturbance could cause it to randomly go off.
