Best Dirt Bike Lock (Which Type Is Best?)

There’s nothing worse than going to where your bike should be, only to find your pride and joy gone! So let’s look at which is the best Dirt Bike lock available today.

There are so many motorcycle locks on the market today.  Most of them are more suited to street bikes because they are so often parked in highly visible locations, open to theft.

As dirt bike riders we face a different set of risks. Many dirt bikes have no key lock, no steering lock, and are not road registered so are very difficult for police to track. This makes them easy targets.

A determined thief with a bolt cutter or disc grinder can get past almost any locking method. The key is to make it enough of a hassle that they will look elsewhere for an easier target.

How to Choose a Dirt Bike Lock

Before you even spend any money on a dirt bike lock, there are many common sense steps you can do to reduce the chances of having it stolen in the first place.

Thousands of bikes are stolen every year. It’s very rare to hear of someone getting their bike back, and if they do it’s usually been thrashed and in need of repair.

Here are some prevention tips to take:

  • Record your bike’s VIN number and engine number. You will need this information to give to the Police.
  • Get your bike insured. Although insurance doesn’t prevent your bike from being stolen, it does give you some peace of mind when it comes to recovering the thousands of dollars you outlaid for your bike.
  • Take photos of your bike. It will help the Police and makes it easier to recognize.
  • Don’t advertise the fact you have a Dirt Bike. The fewer people that know you have a bike in the garage the better. Don’t leave the garage door open for hours on end. Work on and wash your bike out of sight from the street if you can. Plastering your car with dirt bike stickers also advertises the fact.
  • Set up your Garage security. If you are chaining your bike up, it is recommended to chain it to something immovable, like a Security Floor Anchor. It will stop thieves from wheeling the bike out or lifting it onto a truck or van. Loop the chain/cable through the main frame and through a wheel to make it difficult to move, rather than just a wheel that can be removed.
  • Be aware of who is around you. If you transport your bike on an open trailer or the back of a pickup, be aware of who is seeing you. Thieves are opportunists and see a bike being transported as a potential target. If you are in the pits at the track keep it in sight, bikes do get stolen there.
  • Immovable objects to lock to. If you’re parking in the street is there a nearby lamp post or barrier to lock your bike to so that it can’t be carried off?

Top 3 Things to Consider

Materials used:

Ideally, a chain that is made from case-hardened steel is much tougher and harder for a set of bolt cutters to get through.

Chains made from steel with a square or six-sided cross-section make it harder to cut with a bolt cutter.

Similarly, with a disc lock or padlock, a hardened steel shackle is the way to go.


If you are using a metal chain, one with a protective cover will prevent it from damaging your rims and frame.

Disc locks that feature a motion-sensitive alarm are definitely worth looking at. It’s a small extra cost that has thieves running.

Brightly colored locks that draw attention can be all it takes to make them not even try.

Your Budget:

Like most things, you get what you pay for. The more you spend, the better security you get.

A cheap disc lock will act as a deterrent, but won’t slow a determined thief for long. Ideally, a lock that features hardened or case-hardened steel has a better chance against bolt cutters. Evaluate your own set of requirements and look for the best lock within your budget.

Types Of Motorcycle Locks:

There are many different ways to secure your dirt bike, Each has its pros and cons.
Here are some of the best ways:

  • Motorcycle Chain Lock:

Usually a hardened steel chain with a nylon cover to prevent scratching the bike.

More secure than the disc lock and cable lock, but because of its weight, is more suited to securing your bike in the garage, where there is no weight issue if carrying it around in a backpack.

  • Motorcycle Disc Lock:

Fits through the holes in your front or rear brake disc. Probably the most common type of lock because they are compact, lightweight, and cheaper than other types of motorcycle locks.
The disadvantage of disc locks is that they don’t anchor your bike to anything solid, so two people can lift the bike onto a pickup.

  • Motorcycle Disc Lock with Alarm:

Comes with an alarm that senses bike movement. A deterrent that may be enough to scare away opportunist thieves.

  • Motorcycle Cable Lock:

Allows you to anchor your bike to something immovable and solid. Usually made from a braided steel cable about 10mmm diameter.

A 2.5-foot-long cable will allow you to also secure a helmet to your bike, and a 4 to 7-foot-long cable will allow you to secure your bike to a floor anchor point or other suitable lamp post or rail. Make sure you run the cable through the frame and one wheel.

Cable locks are lighter and cheaper than chain locks, so easier carry around, but not as secure, and can be cut with ease by a bolt cutter. More of a visual deterrent.

  • Bicycle U Locks:

A step up from disc locks. The advantage is that they are lighter than chain locks making them easier to transport. The shackle is a thicker diameter,  making it harder for bolt cutters to get a grip.

Make sure that the shackle is at least 15mm thick and hardened steel, with a secure locking mechanism

  • Motorcycle Grip Lock:

Fits over the handgrip and brake or clutch lever. They work by securing the brake or clutch lever to the handlebar grip. They are the cheapest and easiest to use, but also the easiest for a thief to bypass.

Not recommended if you are locking your bike in a high-risk area. Best used as a second line of defense in combination with another type of lock.

  • Wheel Chock System:

Has dual-purpose use because it allows you to securely transport your bike on a pickup, van, or trailer.

It can be paired with a lock to prevent theft.

  • Double Up:

If one lock is enough to slow down thieves, then two are better. If you combine a good disc lock with another form of lock like a chain lock, then the time required to get past two locks has to give you an advantage. One to lock the bike, and another to lock it to something solid so that it can’t be carried off.

1.  AKM Anti-Theft Motorcycle Chain Lock

Best Dirt Bike Locks

In researching dozens of the best heavy-duty chain locks and reading all the reviews, the main negative review on the big-name brands I found was that the chain was great, but the lock was the weakest link. Thankfully that is not the case with AKM chain lock.

  • A nylon sleeve over the chain helps prevent scratches to your bike

Riders should use this mainly as a visual deterrent if they’re in a safe location, or in combination with another form of locking device if in a high-risk area.

7. Lock N Load Dirt Bike Wheel Chock System

  • Allows you to lock your bike to something solid
  • Keeps your bike upright to work on for garage use
  • Front wheel straps mean no compressing of forks to tie down


  • Would recommend additional straps to footpegs or rear wheel when transporting


Even the best locks available from reputable, well-known brands like Kryptonite, Oxford, or Xena which have literally thousands of 5-star reviews, still have one or two negative reviews.

Either it works and your bike doesn’t get stolen, or it fails, and your bike gets stolen. A determined thief with a disc grinder will get past almost anything.

Each lock type here has its pros and cons. The best setup is to use two or more lock types, one to lock the bike, and another to lock it to something immovable.

Combine that with the Prevention Tips above, and you’ve done all you can to safeguard your pride and joy.
