As we know, keeping your bike safe and secure is all about layers of security. And one of those layers that is easy to use and offer great protection is a motorcycle disc lock.

These are super-easy to transport and use, locking through one (usually the front, for better access) brake discs and preventing the wheel from turning. This is useful because, although in itself it won’t prevent the bike from being physically lifted up and put in the back of a van, it will mean it can’t be ridden away.

Here is a selection of motorcycle disc locks that should help you keep your bike safe and sound.

Disc locks in detail

Opportunist thieves may not be able to get your engine running, but if your bike is only protected by its built-in steering lock, that’s easy to get around and then, one can sit on your bike while another pushes it from a moped or similar. With a disc lock in place, they can’t do that and will hopefully move on to the next, unprotected, bike.

While a motorcycle disc lock is not something that you would rely on in isolation – for example, protecting your bike for long periods – it’s definitely a useful addition if you’re popping into the shops or leaving the bike for an hour or two while you go exploring.

What features should a motorcycle disc lock have?

In addition to physically locking your bike and preventing it from being ridden, disc locks can also have additional features built-in, such as Bluetooth location services and high-intensity alarms, to draw attention to themselves if someone is tampering with the bike.

Many will also come with a safety lanyard to remind you to remove it before you ride off – you would be surprised by how many people forget it’s there and get a rude awakening after just a few millimetres of their journey.

Like any security product, look for Sold Secure approval; this not-for-profit testing house is run by the Master Locksmiths Association and rates products by their attack resistance. Look for Motorcycle-rated products with Gold or Diamond being the second-highest and highest standards, respectively.
