This range covers hardened steel chains from Oxford, Kovix, Lok-Up and Whites Motorcycle Parts, with link diameters from 8mm to 10mm, lengths from 1.2m to 2m, and built-in alarm options that sound at the first hint of movement.

How to choose a motorcycle chain lock
Link diameter is the single most important spec. Thicker hardened links resist bolt cutters and angle grinders for longer, which buys time and pushes thieves toward an easier target. The chains here run 8mm and 10mm in hardened or heat-hardened steel, with lengths from 1.2m to 2m so you can loop through both wheels and a fixed anchor.
| Spec | 8mm chain | 10mm chain |
|---|---|---|
| Link diameter | 8mm hardened | 10mm hardened |
| Typical length | 1.2m to 2m | 1.2m to 1.5m |
| Weight | Lower, more portable | Higher, harder to cut |
| Built-in alarm | Up to 120db on Lok-Up | Available on Kovix Hexagon |
| Best for | Daily commute, cafe stops | Overnight, home storage |
Alarmed versus standard chains
An alarmed chain adds a second layer of deterrence. The Lok-Up chain triggers a 120db siren on movement, loud enough to draw attention across a car park. Kovix runs the same principle through its Hexagon alarmed lock. A standard chain relies purely on its 8mm or 10mm hardened links, which is enough for shorter stops where the bike stays in view.
Anchoring matters
A chain is only as secure as what it loops through. Always thread the chain around the frame, not just a wheel, and secure it to a fixed ground anchor or immovable object. Keep the chain off the ground to deny a thief leverage. Pair a 10mm hardened chain with an alarm for overnight security and you have a layered setup that takes serious time and noise to defeat.
Frequently asked questions
What link diameter should a motorcycle chain lock have?
Thicker hardened links resist cutting tools for longer. The chains here run 8mm and 10mm hardened steel. Go with 10mm for overnight or home security and 8mm for portable daily use where the bike stays in sight.
Are alarmed chain locks worth it?
Yes. An alarmed chain like the Lok-Up sounds a 120db siren the moment the chain is moved, adding audible deterrence on top of the physical hardened links. It draws attention fast, which most thieves want to avoid.
How long should a motorcycle chain be?
Long enough to loop through your frame and a fixed anchor point. These chains run from 1.2m up to 2m. A longer chain gives you more anchoring options but adds weight, so match the length to how you park.
