Top 6 Best Motorcycle Disc Locks On The Market 2020 Reviews

1 Kryptonite 000884 Keeper 5s Yellow Disc Lock

Kryptonite’s Keeper 5s starts us off on our search for the best ever motorcycle disc locks available. And everyone will notice this bright yellow disc lock when it is on your motorcycle.

This disc lock weighs 1.24lbs and features a 5.5mm locking pin. It can be slid onto disc rotors up to 6mm thick and can reach up to 41.5mm deep into the rotor to reach the brake disc holes.

Not going anywhere…

The small nature of the locking pin allows you to lock this securely to a wide variety of bikes. It looks sort of like a stapler, and once you close the locking pin into your brake rotor, the movement of your bike will be completely prohibited.

Included is a bright orange flexible cable that you can attach to many points on your bike to remind you that the disc lock is still secured to your bike.

Key Safe Program…

You also have two stainless steel keys for opening and locking the disc lock. These keys can be registered through Kryptonite’s Key Safe Program. This has your back in case you lose the original keys that come with this lock. Plus, you can get one free replacement set of keys with any Keeper 5s purchase.

Kryptonite also offers a lifetime warranty with its Keeper 5s model.

Our rating:4.5 out of 5 stars (4.5 / 5)

Pros

  • Orange reminder cable.
  • Key Safe Program.
  • Compatible with 5.5mm rotor holes.

Cons

  • Yellow paint on the cover is prone to chipping.

2 XENA – Motorcycle Disc Lock Alarm Stainless Steel

This motorcycle disc lock from XENA is their XX6 model. It is another stapler style disc lock but this time with a 6mm steel locking pin. The body of this disc lock is made from Mono-bloc 304 stainless steel and can handle the elements exceptionally well over time. It has also been treated to be resistant towards ice type sprays.

You can slide this lock over quarter-inch rotors and lock into rotor holes up to 41.275mm deep. When you need to lock the pin in place, you simply push down on the locking mechanism on the top of the lock.

Smart Lock Bluetooth technology…

The XENA XX6 comes with built-in Bluetooth technology. XENA has a dedicated application available on both iOS and Android devices that allows you to get the most out of this disc lock. Once you pair the XENA lock with your smartphone and app, you can set the level of the 120-decibel siren, shock sensor, movement sensor, and even the alarms timings.

This lock includes a 3v lithium battery to power itself. Through the app, you can also check your battery level, letting you know when to change it before it runs out of juice altogether.

Love the app…

The overall adjustability you get from using the XENA app is excellent. We especially liked how you can set the exact number of seconds you want the alarm to sound for and how sensitive it is in general.

You will find three stainless steel keys that you can use to lock and unlock the XENA XX6. There is also a fourth key that will enable access to the battery compartment, and that has the specific replacement key numbers etched on to it.

Xena allows you to register your keys online in case you lose them as well.

Our rating:5 out of 5 stars (5 / 5)

  • 6mm steel locking pin.

3 Trimax T645S Hardened Metal Disc Lock – Yellow 5.5mm Pin

Trimax is a reasonably big name in security and has been around for more than 20 years. We were not that surprised when we added their T645S model to our roundup of ideal motorcycle disc locks.

Saw and chisel resistant…

The Trimax T645S is made from hardened metal. Trimax has tested this disc lock to withstand anyone who might try to saw or even chisel it off.

You will find that this disc lock secures directly through the holes in your disc rotor as well. The securing pin on this lock is 5.5mm in diameter. Once you have this lined up with a hole on your rotor, you lock it by simply pushing in on the top of the lock. Trimax also provides you a reminder cable that you can attach to your bike, so you will not accidentally drive off with the lock still attached.

The mini flashlight is a great idea…

This disc lock comes with three keys, on which one of them includes a mini flashlight. The flashlight definitely comes in handy when trying to open the disc lock in the dark.

But there is a catch…

We noticed that the keys were not actually as strong as we would have liked. There was noticeable bending after a few months of use. The keys will still work, but you might find yourself adding some sort of lubricant to the keys and lock to just make it a tad easier to open or close the locking mechanism.

When you are not using the T645S disc lock, you can stow the T645S and the reminder cable away in the handy carry pouch Trimax provides.

Our rating:4.2 out of 5 stars (4.2 / 5)

Pros

  • Flashlight key.
  • Easy to secure on 5.5mm rotor holes.
  • Carry pouch.

Cons

  • You might need to lubricate the lock and keys.

4 Master Lock Disc Brake Lock with Steel Shackle

If you have this next disc lock on your bike, it will be hard to miss since it is bright red. The Master Lock 8303DPS is compatible with rotors that have 6.35mm holes or smaller.

The lock can slide up to two inches deep on to the rotor and is made from zinc and steel. Master Lock has made this lock to withstand the elements and to stop any potential thieves from rolling away with your valuable motorcycle.

Anti-Theft Warranty…

Master Lock includes a $1000 warranty against theft when using this lock. Ok, we know that that probably will not cover the cost of your bike, but it is still better than nothing.

We found the overall quality of this lock to be top-notch. Thieves will think twice before they go and mess with your motorcycle when this disc lock is attached.

Easy to operate too…

The 8303DPS locks by merely pushing down on the cylinder keyhole at the top of the lock. When it comes time to unlock the disc lock, you can use any one of the three keys the 8303DPS comes with.

You will also find a long six-foot reminder cable that you can attach to your bike. It is bright red, just like the lock, so it is also hard to miss when attached.

5 Heavy Duty Anti Theft Motorcycle Disc Lock

BigPantha’s motorcycle disc lock is a bit different than the locks we have looked at so far. This lock features 14mm thick steel that reminds us of a massive padlock.

Restricts movement further…

Where other stapler type disc locks will fit into the holes of your rotor, this lock will fit deeper into the actual slots of your rotor restricting movement even further.

The BigPantha Disc Lock comes with a set of two keys. When you unlock the BigPantha, you will notice that it unpins from both sides. This makes it much easier to slip on or off your motorcycle rotor. It is also covered in a hard plastic that will help prevent any accidental scratches when attaching or removing it.

Pick-proof…

This patented lock is pick-proof, drill proof, and even waterproof, according to BigPantha. Throughout our testing, it held up with the best of them.

Like other motorcycle disc locks, this one comes with a bright-colored reminder cable that can connect to your handlebars. When you are done with the lock, you can also pack it away in the included carry case.

6 Xena X2 Disc Lock X-2Y

We are going to finish our roundup of the greatest motorcycle disc locks with another great stapler style lock from Xena.

The X2 from Xena is their highest security disc lock. It is made from mono-bloc 304 stainless steel that is resistant to any possible weather conditions you might experience.

V-shape makes it more rigid and stronger…

You will notice the V-shaped yellow body of this lock, even in a dimly lit environment. The V-shape of this lock makes the lock more rigid and increases the overall strength of it.

If your motorcycle has rotors that are no more than 47mm thick, you will not have a problem securing this disc lock. The actual locking pin is 14mm thick and made from carbide reinforced steel.

Easy to use…

The key barrel is spring-loaded and easy to lock down without much effort. When it is securely locked, it will even make a click sound to let you know. Once you have secured the lock to your brake disc rotor, you can then attach the included reminder cable to your handlebars.

The X2 does not come with a carry case. It is a bit heavier than some of the other locks we have tested weighing in at 1.36lbs, so that is something you might want to consider when it comes time to store it away.

Xena X2 Disc Lock X-2Y
Our rating:4 out of 5 stars (4 / 5)

Pros

  • Heavy-duty stainless steel.
  • Compatible with rotors up to 47mm thick.

Best Motorcycle Disc Locks Buying Guide

Throughout all our testing, we came across a few key factors that you should consider when buying a disc lock to protect your motorcycle from theft.

Motorcycle disc locks usually look like a big stapler that will attach itself to the disc brake rotor. This will limit the ability of your motorcycle to roll, thus decreasing the likelihood of theft overall.

Get The Size Right

You will want to make sure that you know the size of your rotor holes if you buy a stapler style disc lock. The holes in brake disc rotors can vary from manufacturer to manufacturer, so one size will not fit all.

Best Motorcycle Disc Locks

Smaller disc lock pins can be secured into larger rotor holes. They will still secure your bike, but their overall effectiveness will somewhat decrease since they will sometimes leave gaps and can be moved from position.

Quality Construction

Not all disc locks are made from the same material, and this can affect their reliability and longevity over time. You will find that many disc locks are crafted from hardened steel or mono-bloc stainless steel.

These materials are typically made to be resistant to different types of weather elements and give excellent rust, water, and ice resistance. They can even be crafted to hold up against chiseling or sawing as well.

Since we are going to be sliding metal over metal, though, you will want to be careful not to scratch your brake disc rotor. Fortunately, some disc lock manufacturers cover the disc lock with a rubber or plastic that aids in preventing such occurrences.

Get Smart

Some of the best disc locks even come with integrated smart features. These locks can come with Bluetooth and can be paired directly with your smartphone. You will also commonly find that smart disc locks have alarms and motion sensors built-in, thus increasing the security of your bike even further.

Disc lock manufacturers typically give you a couple of spare keys in case you were to lose one. You will even find manufacturers that allow you to register your disc lock keys online, making it easy to order replacements.

Not all manufacturers provide replacements free of charge, though. The keys typically used for disc locks are also made in a way to help prevent anyone from potentially picking your lock.
