Lock it or lose it | A buyers guide to motorcycle locks

One of the first lessons you learn when you get a bike is to use a motorcycle security of some kind or else it might not be there when you return. However, that ‘might’ from 20 years ago has become ‘likely’ today. Motorcycle crime is rampant and we have to take security seriously if we want to keep hold of our bikes.

As a lock and chain are top of the list for cyclists, so it is for motorcyclists — just on a larger scale. The theory is simple: if your bike is locked to a solid object or ground anchor with a meaty lock and chain, hopefully, it will deter thieves or make them move on to the next bike with a smaller, or indeed no, chain.

The best measure to take though is to use more than one defence device to make your motorcycle appear to be more risk and hassle than the next persons. Other options you can use in conjunction with a lock and chain are disc locks, lever locks, motorcycle covers, GPS trackers and alarms.

We have gathered a selection of motorcycle locks and chains from the big players in the market to see what sort of protection they offer, combined with their usability and portability. Clearly, the larger the chain, the greater the protection it will offer but conversely, the less easy to use it is and as for portability — well, look at some of the weights and you’ll get an idea of how that works.

Things to consider before you buy a lock and chain

When you’re buying security products, look for the Sold Secure logo. This is a not-for-profit scheme run by the Master Locksmiths Association that tests and rates products depending on their resistance to attack.

Look for products that have Motorcycle ratings and, ideally, Gold or Diamond for the highest levels of attack resistance.

Diamond rated

At the top end of the strictly home security scale are massive options like the Oxford Beast. With its 22mm chain links and enormous cylindrical lock, it's serious kit.

Find the Oxford Beast lock here

Tested by Rich Newland for 11 months:

"The trend for heavyweight locks built to meet the Sold Secure Motorcycle Diamond standard, has resulted in some monstrous products and Oxford's Beast is one of them.

"At over 15kg this is home security only. The fat barrel lock weighs 3.6kg, boasts a 30mm hardened locking pin, measures 12.5cm by almost 9cm and would make for an effective sledgehammer if you stuck a handle on it.

"Meanwhile, the 1.5m chain (there is a 2m option at £229.99) weighs 12kg and uses 22mm links. As well as being Sold Secure Diamond rated, it gets an ART 5 ranking for its ability to resist attack and is rated as Secured By Design.
 
"The sheer bulk means it won't work at all with some bikes and if you have wire spoked wheels you may not be able to get the chain through the gaps. But, physical demands aside, it's a serious deterrent - and well worth the investment if you can make its size work with your bike."

The Milenco Dundrod U-lock is another padlock that doubles as a disc lock and is coupled with a Sold Secure Gold rated 14mm chain.

Tested by Dan Sutherland for one year:

"It’s incredibly important to protect your motorcycle from theft. Not just when you’re out and about, but when it’s tucked up at home, too.

"As something of a serial worrier, I like to guard my bikes with the chunkiest, heaviest chains I can, to give me peace of mind it will stay safe when they are parked up overnight. This was particularly important when I moved to a house with the parking situated away from the property, and I called upon the security experts at Milenco to help keep my babies safe and sound.

"Sharing the house with another biker, I opted for the 1.4-metre, 14mm chain and mid-sized Dundrod+ U-lock with the idea being that we could run it through both of our front wheels for shared protection. Weighing in at 9.2kg, the bulky combo works a treat. Not only is it named after one of my favourite road racing venues, but it also provides just enough length to keep both machines together, with multiple keys coming as standard to allow us both access whenever required. 

"Away from the sheer size, the lock passes the Sold Secure Motorcycle Gold standard and remains quite light in your hand. There’s a hefty 14mm shackle to make it harder to cut through too, plus corrosion-resistant coating. I’ve seen no rust on mine, although it has spent its life in dry garages, and the keys have never had any resistance when turning in the lock.

"The chrome-moly steel chain is 14mm thick and whilst I haven’t taken a saw to it, it is claimed to be able to withstand a five minute attack from various tools – which should prove a deterrent if any thieves decide to have a go. 

"Despite its strength, it remains narrow enough to squeeze between the spokes of my old 1996 Honda CG125, too. However, I always aim for the bottom of the rim for fear of the weight damaging the dainty wheel structure. 

"The only criticism I have is of the chain’s blue outer cover, which can sometimes work its way around and bunch up at one end – obscuring the chain loop for the U-lock. This is a minor inconvenience though."

Pros

  • Corrosion resistant
  • Low risk of damaging your bike's paint in use

  • Lock is weaker than the chain
  • Outer cover can bunch up at one end

This heavy-duty lock and chain is just about light enough to carry in a tankbag but it's right on the limit and will be too heavy for some. Even so, it makes a great home security option.

Tested by Ben Clarke for two months:

"The recently updated Oxford Nemesis lock and chain set is a great middle ground between a portable chain you might use out and about and the kind of heavy-duty metalwork you could only realistically deploy at home.

"At 7.7kg (1.2m version), it's a little too heavy to carry with you on the road but the 16mm hardened steel links are more than a set of bolt croppers can munch through, so if you are able to carry it somewhere it offers a great level of security (it carries a Sold Secure Gold rating).

"On the plus side, it's dainty enough to fit between the spokes of most bikes-the fairly tight pattern of the Indian FTR S's cast rims are no problem - and it's light enough to manhandle without issue, too. As an added bonus, the padlock acts as a disc lock when you're out and about and you can arrange the chain in such a way that it's locked to the disc to make it harder for thieves to move your bike around and gain access with cutting tools. The fabric sleeve protects your paintwork and this is the first chain I've used where the studs holding the sleeve in place haven't immediately given up.
 
"The £189.99 price is a little salty but when you consider the lock's double use it doesn't seem so bad. There are plenty of deals to be had online, too."

Pros

  • Just light enough to carry
  • Long lengths available - up to 2m
  • Still fits through most bike rims

  • Chunky and heavy
  • Only fits through bigger ground anchors

"In practical terms, the X3 is incredibly easy to use and has a lot of classy design touches that help to justify the price. The rubberised finish on the metalwork to protect your wheels and fairings from scratches, the self-sealing silicone keyhole cover and even the neoprene carrying pouch to keep the other contents of your motorcycle backpack clean are all beautifully thought through."

"I haven’t personally attacked the LiteLok with an angle grinder, but plenty of independent sources I trust have done so and reported that it is incredibly tough to cut through. I’d be happy to spend my own money on one and it’s become my security of choice whether I’m out and about or at home."

Pros

  • Compact and light enough to carry with you easily
  • Repels angle grinder attacks
  • Can’t be easily bypassed like a disc lock
  • Has to be cut twice to be removed

Cons

  • Bigger and heavier than most disc locks
  • Your bike could still be lifted into a van
  • At the more expensive end of the security market

Chains tested to destruction by RiDE Magazine

The chain itself was horrible to cut, which is a good thing. The disk chattered all over the hardened surface and it was very difficult to bite initially. It felt like the hardness penetrated further into the link than other chains. We didn't try the lock.

Oxford's 16mm chain and D-lock is a hefty product that looked like it should do well. Like its smaller cousin, the Nemesis combination can be used with the lock on its own as a disclock. The silver chain is reassuringly heavy but its size meant it only went through the larger of the two ground anchors. Going at it with the angle grinder, it was very easy to feel the harder outer skin give way to the softer, more pliable inner section before encountering the harder section again. We attacked the lock but unlike the smaller Oxford, we had to go through both sides, as it wasn't possible to get the chain off with just one cut. Semi-circular keys also make picking almost impossible.

Oxford's smaller chain combination comes with a separate D-lock that can be used on its own as a disc lock - handy. However, the plastic cover on the lock looks and feels cheap. It is, however, Sold Secure approved at Silver level for scooters, offering some reassurance. It fitted through both ground anchors, wasn't overly heavy and was very easy to use. The cutting disc went through the chain in just over 30s for both sides but as the lock shackle was exposed, we attacked that as well. It took 28 seconds to go through one side but once cut, we could twist the shackle enough to get the chain off without cutting the other side.

Why we need security kit: how easy is it to steal a motorcycle anyway?

You might be thinking that all this motorcycle security kit seems like a lot of faff, and an extra expense that could be avoided. After all, that’s what insurance is for, and your bike has a steering lock on it already – isn’t that enough?

Well, unfortunately, motorbikes are one of the easiest vehicles to steal, beaten only by bicycles for how quickly thieves can snatch them away. A 2021 study by the Motorcycle Action Group found that motorcycles were 11 times more likely to be stolen than a car, which made them the number one target for vehicle theft by a country mile.

Although most motorcycles have steering locks, these are easily snapped off with a quick kick of the handlebars, allowing thieves with minimal experience to roll away with your ride in mere seconds. Even if steering locks were stronger, it only takes two or three burly blokes to lift a motorbike into a van and be gone just as quickly.

A stolen motorbike is loaded into a van

The fact that unsecured motorcycles are so easy to steal is only magnified by their relatively high value, which makes them the ideal gig for crooks of any calibre to quickly cash in on – at your expense. All this makes it important to keep your ride locked up safe wherever you go – especially when parking up outside your home for the night, where most bikes end up being stolen from.

Of course, no security measure is completely bullet-proof, and you can’t expect to stop the cartel from ‘donating’ your bike for their ‘charitable’ causes if they really want to. But that is what insurance is for. Motorcycle security products will help you keep your ride where it belongs, so you don’t have to worry about your bike being stolen any more than you would for your car.

How MCN tests security

At MCN, our team of expert journalists have decades of experience gained over hundreds of thousands of miles. We don’t usually test our security to destruction; we use it exactly how you do, in the real world and in all conditions, while also being on top of the key safety and security regulations. That means we can deliver impartial buying advice you can rely on.

Each of our writers has an in-depth understanding of the needs of today’s biker… because they are one.

To find out if a security is worth spending your money on, our testers use them in the way you will. That means riding in them in whichever conditions they are designed for.

If you can’t see a review against an item on this page, it’s because we haven’t tested it yet. These items will only be included if we think they’re important and relevant in the market, and rest assured, we will be working on bringing you a review as soon as we’ve done the miles.

What our star ratings mean

When we review a product, we award it a score out of five. In the ratings tab of a given product, you may also find more specific scores for the different aspects of a product’s performance to help you make an informed decision. Here’s a guide to what each number score means:

  • 1 star – Poor performance in this category or overall. A product with a single star rating has fallen below the expected standard and should be avoided.
  • 2 stars – Basic performance in this area or overall. A product with a two-star rating has managed to perform to a barely acceptable level and there is room for improvement.
  • 3 stars – An average performance in this area or overall. A product with a three-star rating has achieved a basic level of performance and is deemed adequate.
  • 4 stars – A product has performed over and above the accepted averaged in this category or overall. A product with a four-star rating has surpassed expectation and delivered in a particularly impressive way.
  • 5 stars – A product has performed at the highest possible level in a particular category or overall. A product with a five-star rating has delivered to the highest possible level, impressing the tester with its performance. We would happily spend our own money on it.
