A disc brake lock can be used as a sole safety solution or together with other safety products. They can include:

  • Chains with locks.
  • Ground anchors
  • Bike trackers
  • Sheds
  • Garage door defenders

With most of these other safety solutions, a disc brake lock provides an unobtrusive extra measure to protect the motorcycle from theft. However, common sense should be applied even with a disc brake lock. Riders should avoid storing their motorcycles out in the open or in areas which are favor theft.

The durability of the materials

A good reason to use a disc brake lock comes with the durability of its materials. From regular steel to forged steel added aluminum or other metals, these materials are known for their durability. Typical testing involves the durability against cuts or drilling. Most disc brakes should offer a minimum barrier from this perspective.

But the materials of the disc brake lock can also vary according to its design. In some cases, the inner sensors also need to be protected. While they can be accessed and disabled, it would take a long time to achieve this. It is why thieves do not prefer to stand around for too long.

The benefits of an audio alarm

Some of the best disc brake locks come with included alarms. These alarms are usually very loud. They represent one of the best solutions when it comes to an extra measure of safety, as is the case with motion sensors.

Alarms are based on a simple sensor powered by batteries. It won’t work with drained batteries. Alarms can also go off with no reason at all. But in most cases, an alarm can act as a strong deterrent for those trying to move a bike.

Thieves trying out different keys on the lock will also have the surprise of triggering the alarm. In a few cases, the alarm is directly activated when the wrong key is inserted in the lock. At the same time, the alarm can also come with various programming which can ensure a delayed response or a continuous noise made every 5 to 10 seconds.
Apart from these aspects, alarms have no other benefits. They do not automatically call the police and they can be just a drop in the ocean if the motorcycle is parked far from homes or populated areas. This is why even when using a lock which comes with an alarm, it is still wise to park the motorcycle in a safe area where it has at least some level of supervision.

The real benefits of a motion sensor

Motion sensors are worth the purchase of a disc brake lock on their own. Whenever someone moves the motorcycle, the motion sensor activates the alarm. Before thieves even have the capacity to get the motorcycle started, the alarm goes off. This means the sensor can act as an extra safety measure. However, most issues users have with disc brake alarms are actually caused by the motion sensor. Often activated by the wind, it only leads to false alarms. But for most motorcycles, this small discomfort is still not a considerable issue to overlook from time to time.

Advantages and drawbacks of a compact safety solution

As a compact design, a disc brake lock might have its weaknesses such as reduced strength compared to large chains and locks. However, it also has some benefits, especially in the area of portability. Practically, the disc brake lock can easily fit in the pocket of a motorcycle vest. This is why there are good reasons to consider the disc brake lock as the friendly design which goes everywhere with the ride.

Those traveling a low know that all safety solutions can’t be carried along. In most cases, motorcycles are stored in a garage at home. But while away from home, a set comprised of a disc brake lock and an additional chain with a lock can be enough.

Final words

Leading in terms of physical strength and compact size, disc brake locks represent one of the simplest yet most efficient safety measure motorcycle owners can consider. Their prices vary but they are still low compared to many other safety options.

Most importantly, the best disc brake locks come with a range of characteristics which make them harder and harder to overpass. The most important characteristic is still represented by its materials, which need to resist various tools. Other features include various alarm sensors which can act additionally or even before those with bad intentions get close to the disc brake lock.

While a disc brake lock is mounted, the motorcycle can move. This means that even if it starts, the motorcycle cannot go anywhere until the lock is opened with its original key. This is an important aspect as some disc brake locks will sound an alarm whenever someone tries to pick the lock.

For insurance purposes, it might also be important to see which other safety solutions
would bring the monthly cost down. Just because an insurer doesn’t require a disc brake lock doesn’t mean it can’t be considered alongside the mandatory safety solutions. It proves that in all cases, the more safety solutions can be applied, the safer the motorcycle is, even if parked in a garage at home.
