We're keen to dish out some security advice to help people who aren't sure about what they need to keep their bike safe. It's worth noting at this point that a huge majority of bikes that are stolen have absolutely no security at the time of the theft, meaning the steering lock is snapped and the bike is simply pushed away, like the one below. That being said, there are quite a few decent articles on security already available, so we will just aim to give some tips based on the bikes we take off the street.
Firstly, anything below 16mm can be cut using bolt croppers, so aim to get something larger than that - ideally 22mm or so.
If you're out and about, it's not always easy to carry around massive chains. We recommend the BikeTrac hard security range, which includes a reinforced chain which is also bolt-cutter proof.
To go with your Almax or Pragmasis chain, we whole-heartedly recommend Squire locks. These can be purchased through Almax using the link above. No matter what you use, please avoid tubular locks as many are susceptible to low-skilled picking attacks and can be relatively easily opened.
The most common type of security used on motorcycles and also possibly where there are the most cheap, useless products on the market. The main weakness of a disc lock is the "U" shaped design. We find that many can be removed within seconds (without damaging the brake discs) as pressure applied will either snap the U in half or will bend it sufficiently that it can be removed from the disc with ease.
We are doing some research and will update this section shortly, although we do recommend the Abus 8077 as its design avoids it being prised apart easily.
The best form of reactive security, these allow you to recover your bike once it gets stolen. There are only two companies we'd recommend for trackers and they are both fairly similar in that they operate 24/7 monitoring centres which will keep an eye on your bike once the ignition is switched off and will alert you if there is any movement.
These are pricey, but once again, they are probably cheaper than having to replace your bike if it's stolen and will reduce your insurance premiums in the long-run.
We recommend BikeTrac and Datatool. We feel that BikeTrac has an advantage over Datatool, simply because the trackers can be pinpointed if the bike is stashed away in a garage, or an underground car park.
