High Security Motorcycle Locks

Many UK motorcycle insurers ask for a Sold Secure Powered Cycle Diamond rated lock as part of their security requirements, and all LITELOK X-range Moto locks hold this rating. However, insurance terms vary between providers and policies, so you should always check your own policy documents or speak to your insurer.

You can view each lock's Sold Secure certification for the exact rating awarded. If your insurer requires a specific security standard, a Sold Secure Powered Cycle Diamond lock may help you meet that requirement.

Some riders report receiving lower premiums or improved insurance terms after using a Sold Secure Diamond rated lock, but this depends entirely on the insurer and individual policy.

Most motorcycles can be secured through the brake disc, wheel or swingarm with a LITELOK X-range Moto lock, but fit depends on your bike's wheel, tyre and brake setup.

All X-range Moto locks have an internal width of approximately 100mm. Internal lengths are:

• X1 MINI Moto: 137mm
• X1 Moto: 196mm
• X3 Moto: 195mm
• X1 PLUS Moto: 255mm

If you're unsure, check our fitment gallery, which includes 500+ motorcycles logged by riders and the LITELOK team. You can see real-world fit examples before you buy.

Riders with wider tyres or larger components on bikes such as the Kawasaki Versys and Ducati Multistrada should check fit carefully, as clearance can vary between models and model years.

The best motorbike lock depends on your threat level and how you ride. For maximum security against angle grinders and power tools — the methods professional thieves use — the LITELOK X1 Moto, X1 PLUS Moto, X1 MINI Moto, and X3 Moto are your strongest options, built with patented Barronium® technology to actively resist cutting attacks. The X3 Moto adds an ABLOY® SENTRY cylinder — the most pick-resistant cylinder available — and four times the Barronium® coating of the X1 Moto for the ultimate level of protection. For lighter everyday use or as a second layer of security alongside a D-lock, the Boaflexicore® CORE Moto offers excellent protection in a flexible, carry-friendly design. As a general rule: match your lock's security rating to the value of your bike and your level of risk.

Yes — if your motorcycle is worth protecting. Angle grinders have become the standard tool for organised motorcycle theft, capable of cutting through most standard locks in seconds. A high-security lock like the LITELOK X1 Moto or X3 Moto dramatically increases the time and effort required to defeat it, and most thieves will simply move on to an easier target. The cost of a high-security lock is almost always less than your insurance excess, let alone the cost of replacing your bike. Many riders find their insurance premium drops after fitting a Sold Secure Diamond rated lock — enough to offset the cost of the lock entirely.

Both use Barronium® to resist angle grinder attacks, but they differ in the level of protection and the cylinder. The X3 Moto has four times more Barronium® coating than the X1 Moto and comes with the ABLOY® SENTRY — the most pick-resistant cylinder available. The shackle legs of the X1 Moto measure 25.5mm × 22.5mm with the polymer coating (18.6mm × 20mm without). The X3 Moto shackle legs measure 27.5mm × 24.0mm with coating (22.5mm × 20mm without). If you ride a high-value motorcycle or park in high-risk areas, the X3 Moto is the stronger choice. Both carry a Sold Secure Diamond rating for Powered Cycles and Motorcycles.

For a full side-by-side comparison, including which one to choose for your bike or motorcycle, see our LITELOK X1 vs X3 comparison.

Locks engineered to resist angle grinders are the hardest to defeat, as angle grinders are the most powerful cutting tool used by modern bike thieves. Within the LITELOK range, the X3 Moto offers the highest security rating, followed by the X1 PLUS Moto, X1 MINI Moto and X1 Moto. Standard steel D-locks and chain locks without specialist materials can typically be cut in under a minute with an angle grinder, regardless of their weight or price.

Consider three things: where you park your bike, how long it's left unattended, and how much your motorcycle is worth. For overnight parking, touring, or high-theft areas, choose a Sold Secure Diamond rated lock like the LITELOK X1 Moto or X3 Moto. For shorter stops or as a complementary layer alongside a D-lock, the CORE Moto gives you practical everyday security without the bulk. A good rule of thumb is to spend around 10% of your bike's value on a lock — and prioritise security rating over size or weight alone.
