How to choose a motorcycle lock
Layered security defeats most thieves. A 120dB alarm disc lock warns you and scares off opportunists, while a hardened chain rated 10mm or 14mm anchors the bike so it cannot be lifted into a van. Lock ratings follow the same logic as protective gear standards like EN 17092 and CE Level 1 and Level 2 armour, where a higher class means more resistance.
| Lock type | Key spec | Best for |
|---|---|---|
| Disc lock | Pin 6mm to 10mm | Quick stops, up to 90 seconds to fit |
| Alarm disc lock | Up to 120dB siren, 6mm pin | Street parking and shared garages |
| Hardened chain | 8mm to 14mm links, 1.5m to 2m | Anchoring at home overnight |
Spec the right strength
Chain link thickness drives resistance. An 8mm chain suits low-risk daytime use, a 10mm chain steps up bolt-cutter resistance, and 14mm hardened links target serious overnight security. Boron and hardened steel resist hand tools far better than standard 6mm chain. A 2m chain reaches around a ground anchor or solid post, while a 1.5m chain is lighter for daily carry. Fit the disc lock to the rotor and use a reminder cable so you never ride off with the lock attached.

Frequently asked questions
What is the difference between a disc lock and a chain lock?
A disc lock clamps onto the brake rotor to stop the wheel turning and acts as a visible deterrent for short stops. A hardened chain loops through the wheel and around a fixed anchor point so the bike cannot be lifted away, making it the stronger choice for overnight security at home.
How thick should my security chain be?
For daytime and low-risk parking an 8mm chain is fine. Step up to a 10mm hardened chain for everyday street use, and choose 14mm hardened or boron links for serious overnight protection where the bike is left unattended for long periods.
Do alarm disc locks really help?
Yes. An alarm disc lock fires a siren of up to 120dB when the bike is moved or tampered with, drawing attention and deterring opportunist thieves. Brands like Kovix and Oxford include reminder cables so you do not ride off with the lock still fitted to the rotor.
