How to crochet a motorcycle lock?

Is it easy to crochet an anti-theft hardware lock? How does a thief do it? What is a good lock recognized?
Unless you are riding a motorcycle so ugly that no one wants it, a lock is anything but a motorcycle accessory, especially in big cities. U, padlocks, chains, disc blocks and shielded cables offered by manufacturers have varying specifications that partially reflect their price and weight. Most often, a "good" castle is heavy and expensive.
Standards are an additional guarantee of durability, but not sufficient. The NF standard was one of the safest, superseded today by the SRA (Automotive Safety and Repair) standard. FFMC also regularly conducts anti-theft stress tests, the best of which last a maximum of a few minutes.
In fact, there are exceptions: expensive locks are embarrassingly easy to force, or, conversely, simple external devices are surprisingly resistant to attempts at engagement.
How to understand how locks work in order to choose the best? A passionate person gives you the secrets of crocheting or how to open a guard without breaking it.
Secrets of opening locks
There is no scary music, no dramatic commentary. Ugh! Just a padlock, padlock or padlock and simple tools. After a few minutes, the lock engages and is often taken apart to explain how it works, its strengths and weaknesses. The author took an unsophisticated approach to the educational video: even with a limited level of English, it's easy to understand what's going on.
Three notes:
- it is very easy to crochet a lock when you have little equipment and especially a lot of training;
- it is not technically very difficult to make complex crochet locks, which makes one wonder when manufacturers still sell padlocks that open with a simple paper clip or sheet of metal;
- These videos allow you to better understand how the lock works and distance yourself from blah-blah-blah-blah-blah-blah-blah-blah-blah-blah-blah-blah-blah-blah-blah-blah-blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah
Proof? Bonded steel disc block ... hooked in less than a second!

In this example, if he gives a good point of view for making case hardened steel, when other models are content with zinc alloys that are too easy to twist or drill, he manages to open the disc block with almost one finger with a simple metal strip.
"Sufficient" lock according to the author of the YouTube channel: it takes 45 seconds to open it ... without a key!

He notes that the links in his chain, which are hexagonal in section, are more difficult to attack with a bolt cutter due to their straight surface. He then explains that the chains, when they cannot be held on the ground by a thief, are more difficult to attack with a disc machine than U, and are easier to hold. Thus, thieves will hesitate to use composite discs, which are more efficient than diamond discs, but are very fragile and will likely break if the disc matures. Finally, you will notice that the links have a center reinforcement that limits the torsional potential of the shear bar into the links.
This is the kind of information that should be kept in mind when choosing a channel.
Cables make very bad locks

Should we remember this? Cables cut too easily to make good burglar-proof devices. No need to even use a large bolt cutter: a simple clamp specialized in cutting copper electrical cables is enough to cut through four layers of cables with my pinky diameter.
Contactors
Finally, we see what he manages to do with this contactor for Harley-Davidson, which he manages to open in ... a tenth of a second! This is because Harley has retained the round barrel model, which has two vulnerabilities well known to thieves, so that this lock can be opened with a mat not sold for 10 euros each on the Internet.
Videos explaining what makes a good castle
These videos have the advantage of drawing shoppers' attention to items that need to be checked.
For example, looking inside the U lock block gives you an idea of its quality: using balls for locking is safer than metal rods.
"Cemented" steel? A good file lets you check. We concluded that it would be better to adopt a very good lock instead of a disc lock, as the author explains exactly how to modify the barrel to make it more secure.
We may worry about the ease with which it works, but remember that it works in optimal conditions, in a well-lit workshop, after a lot of training. He is not on the street or in a dark parking lot, in an uncomfortable position, in a more or less rusty airlock, at risk of getting caught, etc.
You will notice that these videos focus on "non-destructive" attacks. He sometimes uses hand or hydraulic bolt cutters, pliers, or torches, but the bulk of his job remains to explain the vulnerabilities of these devices to a person with much more restrained tools to use and therefore much more dangerous to the desired object.
It's easy to blame these videos for training thieves as well. However, the informed biker will be able to make a more informed choice in front of the lock shelf once he learns to recognize some of their faults.
How to use the anti-theft device correctly
Finally, remember that the purpose of the anti-theft device is not to permanently immobilize the motorcycle, but to immobilize it long enough for the thief to feel the risks of being spotted are too high.
Hence the importance of correct positioning of the lock: never on the ground, always lock or face the wall, accepting two fork tubes instead of one, or a swing and a wheel stick instead of a single wheel stick, and so on.
Some people think they are doing well by tying a chain wrapped around a pole with a U attached to the motorcycle. It's a good idea ... as long as the chain is not on the ground with a net, the ground will support the thief's bolt cutter.
As we have seen: cables should be banned. A simple clamp overcomes it very easily. The disc lock can only be used as a backup equipment, long enough to pick up the wand, or in combination with another chain or U-lock.
In short: buying a good homologated lock is good, getting a better understanding of how it works, and putting it on your bike well, that's perfect ... except for settling on a really ugly bike.
Bonus: the story of the very first "U" kryptonite

In short:
- choose an approved / certified lock
- attach your U to a fixed point
- disagree with packaging promises
