Product Information

Full details

The Squire Defiant Disc Lock is designed for motorcycle owners seeking premium, high-level anti-theft protection for their vehicles. Its primary benefit is its industry-leading resistance to physical attacks, including angle grinder attempts and force-based removal, making it a top-tier security choice for urban or high-risk environments. The main caveat is that its heavy-duty, hardened steel construction makes the lock significantly heavier than standard budget alternatives, which may affect portability.

FAQs

Is this lock waterproof?

Yes, the Squire Defiant is built to withstand all weather conditions, making it suitable for year-round outdoor use.

Does it come with a replacement key service?

It comes with two precision-engineered keys. We recommend keeping one in a secure location as a spare.

Will it fit any motorbike?

The 12mm shackle is designed to fit most standard brake discs. Please measure your disc ventilation holes to ensure clearance.

Why is the reminder cable included?

The reminder cable serves as a visual aid to remind you that the lock is attached, preventing you from trying to ride off and damaging your motorcycle.

How often should I clean the lock?

Depending on usage, a quick wipe down and occasional lubrication of the keyway every 3 to 6 months is sufficient.

Troubleshooting

Key is difficult to insert or turn

Ensure the keyway is free of debris and apply a small amount of silicone lubricant. Check that the key is fully inserted.

Shackle does not lock into place

Clear any dirt or road grime from the shackle holes and the lock body. Ensure the shackle is aligned perfectly with the internal pins.

Difficulty removing lock from disc

Check if the bike has settled or moved, placing tension on the lock. Gently roll the bike slightly to relieve pressure on the disc before unlocking.

Pros and Cons

Pros

  • Unparalleled resistance to angle grinders and power tools
  • High-security 6-pin cylinder with extreme key variation
  • Weather-resistant construction suitable for outdoor use
  • Sold Secure Powered Cycle Diamond Approved status
  • Includes essential accessories like a reminder cable and pouch

Cons

  • Weight is significantly higher than entry-level locks
  • Requires careful alignment due to the robust shackle design
  • Limited to use on compatible brake discs

Setup, Compatibility & Care

To install, ensure your motorcycle's brake disc has an aperture large enough to accommodate the 12mm shackle. Simply slide the shackle through the vent hole, align the ends with the lock body, and press until you hear a secure click. To maintain the locking mechanism, it is recommended to apply a light silicone-based lubricant into the keyway every few months, especially if the bike is stored in harsh, salty, or rainy conditions. Keep the locking area free from excessive road grit by wiping the shackle down with a damp cloth periodically.
