LITELOK X1 is armoured with Barronium™, a patent pending composite material that resists angle grinder attack by turning the grinder's energy and force in on itself.

Barronium™ is permanently fused to a hardened fine-grain high-tensile steel core which provides Motorcycle Diamond levels of protection against all other commonly used tools such as bolt croppers, cable cutters, long bars, hammers and chisels.

Armoured D-Lock for Motorcycles & Scooters



Barronium™, our new composite anti-grinder armour, is fused to a hardened fine-grain high-tensile steel core to provide protection against multiple tools attacks, including angle-grinders, bolt croppers, cable cutters, long bars, hammers, chisels and more.


X1 locks are finished with Quartz White retro-reflective vinyl strips along the lock shackle and on the X's at each end. These offer increased visibility of the lock to deter thieves and remind you it’s fitted. X protects the spot. 


LITELOK X1 weighs just 1.7kg, far lighter than any motorcycle chain yet still offers Diamond level protection & angle grinder resistance. It’s also easily stored in your backpack or panniers when not in use. 


The plant-based eco-rubber outer layer is sourced from 80% non-food grade crops, which dramatically reduces the amount of petrochemical plastic required in the manufacturing of our locks. Due to the nature of these materials, any waste generated during production can be recycled and re-used in our solar powered manufacturing facility in South Wales.



If you don't own an armoured D-lock then your bike is not protected against angle-grinders, which is increasingly becoming the tool of choice for bike thieves.



Litelok X1


Barronium™ is a fused composite armour that offers unparalleled angle grinder resistance without adding extra weight. It is a super hard ceramic composite material that repels angle grinder attacks and turns the grinder's energy and force in on itself. Continuous cutting wears down the grinder discs, batteries and ultimately the grinder motor itself.
