If you're a city rider, then you’ll know that keeping your motorcycle safe can feel like a full-time job. With theft rates for bikes significantly higher in urban areas, investing in a reliable, insurance-approved motorcycle lock isn’t just a good idea; it's essential. 

Finding the right lock can make all the difference in protecting your pride and joy and meeting your insurer's security requirements; however, make sure you are fully aware of these and that you are complying with them. Failure to do so could invalid any theft or attempted theft claims. 

With so many options out there, it can be hard to know where to start, especially if you're a new rider yourself or unsure what your insurance provider expects…so, that's where we come in! In this guide, we’ll guide you through our top picks! 

Before we dive into the locks themselves, it’s worth understanding just how big a problem motorcycle theft is, and why it’s important to invest in proper protection. 

Unfortunately, motorcycle theft is a bigger problem in the UK than most probably realise, and high rates are in urban areas like London. They are a highly targeted vehicle type, especially lower-powered scooters and new models that lack security features. 

This is often because they’re lighter, easier to move, and can be stripped for parts in minutes. 

A bike lock is an essential part of keeping your motorcycle safe, but it shouldn’t be your only line of defence. 

The best security comes from a multi-layered approach using a combination of a high-quality chain or U-lock, a disc lock, and the built-in steering lock. Whenever possible, secure your bike to an immovable object, such as a ground anchor or lamppost, to make it much harder for thieves to lift or move it.

According to the Met Police’s security advice, combining several layers of protection is the best way to keep thieves away…

• Use multiple locks
• Install a tracker or alarm system
• Park in well-lit, CCTV-monitored areas
• Cover your bike to avoid unwanted attention
• Take removable parts with you

Choosing a motorbike lock isn’t just about cost; it's about matching security needs and insurance requirements. 

You’ll need to consider factors like your budget, the weight of the lock, and whether it's weather-resistant, while also ensuring the lock fits your specific bike's dimensions before buying. 

Sold Secure is the recognised UK testing standard for motorcycle locks. Their ratings: Bronze, Silver, Gold, and Diamond show how resistant a lock is to theft. 

You can check a lock’s Sold Secure rating by looking at the packaging, searching the Sold Secure Approved Product List on their website, or reviewing the product description on the retailer’s page.

 Different types of locks serve different purposes: 

• Disc brake locks: Compact and easy to use; ideal for short trips
• Chain locks: Heavier but highly secure; good for long-term parking
• U-locks/D locks: Strong and resistant to leverage attacks
• Alarmed locks: Added deterrent with sound alerts
• Choose an insurance-approved bike lock

Many insurance providers only accept certain locks, so make sure to give them a call before purchasing. Choosing an approved lock not only protects your bike but also ensures that you meet insurance conditions in case of theft. 

Now, onto what you probably came for, I’ll run you through our top 10 bike lock picks, including their rating, price, and weight, to make things a little easier for you. 

The Squire Defiant Motorcycle Disc Lock is a Sold Secure Diamond-rated lock built for serious protection on the road.

It uses angle grinder–resistant armouring and a solid 25mm hardened steel body, with a 12mm boron steel shackle to keep things tough. It's compact, therefore easy to transport with a protective pouch for carrying.

When it comes to serious bike security, the LITELOK X1 Moto is in a league of its own.

This isn’t your average D-lock, it’s armoured with Barronium®, a unique, patent-pending material that literally fights back against angle grinders. Instead of giving way, it turns the grinder’s own energy against itself, making cutting through it nearly impossible.

That means it offers five times more resistance than most of the best-selling D-locks out there, and it manages that without piling on the weight.

D-Lock	Diamond	£149.99	1.7kg

 

The Oxford Monster is a tough, Thatcham-approved disc lock. Made from hardened Ni-Cr-Mo alloy steel with a double-locking mechanism, it delivers serious strength and reliability.

Its widened access points make it easy to fit on bikes with larger brake discs, and it can even be paired with a chain for extra security. Rugged, versatile, and insurance-approved, the Monster is a solid choice for riders who want peace of mind without overcomplicating things.

Disc Lock	Gold	£44.98 - £74.99	0.7kg

 

Similar to the brilliant LITELOK X1, the LITELOK X3 takes things up a notch, it’s the most secure full-sized armoured D-lock you can buy. 

Again, like the X1, it’s built with Barronium, but the X3 delivers a massive upgrade in protection, offering up to 20 times more resistance than standard D-locks, all without adding extra weight.

The X3 is one of the most secure full-sized D locks in the market, whilst also being easy to use; however, it is on the heavier side. If you loved the X1 but want the absolute maximum in grinder-resistant security, the X3 is your ultimate upgrade.

Powered by a long-life lithium battery.

The Oxford Quartz XD10 Disc Lock is a compact yet heavy-duty lock designed to keep your motorcycle safe.

The ABUS GRANIT Extreme Plus 59 is a heavyweight security solution built for serious protection.

It's got 12mm chain hardened steel links to resist cutting, a matching lock housing and mechanism made from hardened steel, and ABUS’s patented Power Link which connects chain and lock into a single, tamper-resistant assembly. 

The lock uses the XPlus cylinder to protect the keyway from picking and drilling, and it’s supplied with a Transport Bag (ST1010) for chains up to 140 cm. Designed for very good protection in high-theft areas and recommended for high-value motorcycles, the length options make it easier to secure the bike to fixed objects - the longer the chain, the more anchor options.

Chain Lock	Gold	£134.99	2.7kg

 

Up next is the Oxford Beast Lock and chain, and as the name suggests, it's not here to mess about.

This is Oxford's strongest ever padlock and chain; it has a 30mm hardened locking pin, whilst the chain has 22mm hardened steel links, weighing 15.5kg, so it's going to keep the bike secure. It's passed its attack checks from a range of tools commonly used by thieves, such as an angle grinder, giving it a diamond sold secure 5-star rating.

So, if you’re after something to truly keep your bike safe, this one is a top choice.

Chain Lock	Diamond	£169.99	3.6kg lock & 15.5kg chain

 

In first place is the Hiplok DX1000, the bigger, tougher sibling to the award-winning D1000. Built with motorcycles and larger-framed bikes in mind, it uses the same specialist composite material that made the original famous for its incredible resistance to angle-grinder attacks. 

The anti-rotation double-locking tabs mean a thief has to cut through both sides to stand a chance. The rubberised outer keeps your frame scratch-free, and you can carry it easily with optional mounts or sleeves. With three coded, replaceable keys and a lifetime warranty when registered, the DX1000 is a rock-solid upgrade for anyone serious about security.
