Disc Locks

About

Disc locks are the fastest, most portable way to stop a thief from rolling your bike away. This range pairs Oxford, Kovix and Zumolock hardware, from compact pin-only models to alarmed units that scream when tampered. Pick a hardened pin that fits your rotor holes and lock up every time you park. How to choose a motorcycle disc lock The right disc lock comes down to three numbers: pin diameter, alarm volume and if you will actually carry it. A thicker pin resists bolt croppers, a louder alarm draws attention, and a smaller body is easier to keep in a jacket pocket so you never skip locking up. Type Pin diameter Alarm Best for Compact pin lock 5 to 6 mm None Scooters, daily errands Standard pin lock 10 mm None Home and known parking Alarmed disc lock 7 to 14 mm 100 to 120 dB Street parking, travel Always check your rotor. Most road bikes use 5 mm or 6 mm holes, while larger adventure and cruiser rotors take a 10 mm pin. Oxford Quartz models cover both the XD5 5 mm and XD10 10 mm fitments. Alarmed units like the Oxford Screamer and Alpha XA14 add a 100 dB to 120 dB siren triggered by motion, so a thief gets roughly 3 seconds before the noise starts. Use a bright reminder cable. A 1.5 m coil running to your bar or mirror stops the number-one disc-lock mistake: riding off with the lock still fitted and bending your caliper. Kovix builds hardened stainless bodies rated to resist corrosion in wet Australian winters, and most quality locks carry a 2-year warranty. The Kovix KNN1 uses a 14 mm pin for higher-end security, while a 6 mm cable adds a visual deterrent. Combine a disc lock with a chain through the rear wheel for layered security at home.
