When you put on your motorcycle gear, you rely on a simple promise: if it goes wrong, this stuff protects me. The visible sign of that is the CE label. Manufacturers advertise AAA, Level 2 and EN 17092. But if you look more closely at the test procedures, you'll know that there are often worlds between a lab test and a real slide over rough tarmac. Even an expensive jacket with an AAA rating can reach its limits in a crash.
This is about why an AAA certificate isn't a licence to ride flat out, and why the standards sometimes even hold back better protective clothing.
1. How the CE standard for motorcycle clothing came about
Before criticising the tests, it's worth looking at why they exist at all. Until 2018, motorcycle clothing was a bit of a free-for-all. There were standards for gloves and boots, but jackets and trousers were often sold as plain leisure wear. That way manufacturers saved themselves expensive testing.
Since 21 April 2018 the PPE Regulation (EU) 2016/425 has been binding. Since then, motorcycle clothing that promises protection is officially PPE (personal protective equipment), and the matching standard is EN 17092 (since 2020). For consumer protection that was a big step forward. The catch: compared with the old professional standard (EN 13595), the abrasion requirements are significantly lower.
The trade-off: safety or comfort
EU regulators had two options:
Strict standards: only heavy leather and very thick textiles pass. The result: nobody wears it in summer because it's too hot and uncomfortable.
Flexible standards: lighter clothing gets certified too. The result: more people wear protective clothing, but protection per square centimetre drops.
They chose the second route. That produced today's classification from C to AAA.
2. Lab versus road: where physics contradicts the standard
The Darmstadt machine: sliding under lab conditions
At the core of the current test is the "Darmstadt machine". Fabric samples are mounted on arms, brought up to a set speed and then dropped onto a concrete surface.
The test: the sample hits the concrete at test speed and slides to a stop. The test is passed if no hole larger than 5 mm has formed.
The reality: a motorcycle crash almost never starts with you lying flat on the ground. First comes the impact, then an irregular sliding phase.
The criticism: the machine simulates a fairly smooth, even load. Real tarmac is rough, has potholes and edges. These edges bite into the fabric and tear it open instead of just slowly grinding it down. A fabric that does well on the concrete slab can rip open in milliseconds on a coarse country road.
Friction and heat
What CE tests often leave out is heat. When material rubs over tarmac, a lot of frictional heat builds up in a short time.
Leather is a natural material. It chars but keeps its structure.
- Synthetics (nylon, polyester) are plastic. And plastic melts.
Many cheap CE-tested textile trousers contain simple membranes or linings made of polyester. Once the outer shell has worn through (which happens quickly with class A), the plastic melts straight into the burn. The CE standard checks whether a hole forms. It doesn't assess how severe the burn from molten material is.
3. Armour: putting level 1 and level 2 in context
Armour is tested to EN 1621. A 5 kg weight is dropped onto the protector, and the force that still gets through underneath (in kilonewtons, kN) is measured.
| Level | Test energy (drop energy) | Permitted transmitted force (average) |
| Level 1 | 50 joules | < 35 kN |
| Level 2 | 50 joules | < 20 kN |
Why these numbers are deceptive
A level 2 protector may still let through almost 20 kN on average, a level 1 protector almost 35 kN. That's much less than without a protector, but still an enormous force. A broken bone is by no means ruled out.
Where the standard has gaps:
The area: what's measured is the peak force under a standardised test body at set points. How well the protector spreads the energy across its whole surface is only partly reflected in the rating.
Temperature: protectors made of visco foam (such as SAS-TEC or D3O) behave very differently at 35 °C in summer than at 5 °C in autumn. Tests at +40 °C and −10 °C are only optional in the standard (then T+ or T− is marked on the protector). Many cheap protectors lose a lot of their protective effect outside their comfort zone.
Coverage: a protector can be level 2 and still be tiny. The standard prescribes minimum sizes, but these often don't cover the sensitive joint heads when you move during a crash.
4. The AAA misunderstanding with motorcycle jackets
In marketing, "AAA" counts as the gold standard. What's really behind it?
An AAA rating under EN 17092 means that the material in zone 1 survived the drop from a test speed equivalent to 120 km/h without a hole larger than 5 mm (zone 2: 75 km/h, zone 3: 45 km/h). That's a lab value, not a promise for a crash at 120 km/h.
That sounds like a lot. But the old EN 13595-1, intended for professional use, required for its level 2 an abrasion resistance of 7 seconds on an abrasive belt (Cambridge machine) in zones 1 and 2. Comparison tests by BikeSocial put AAA under EN 17092 65 to 80 % below the old level 1, depending on the zone.
The comparison makes it clear: a current AAA jacket often wouldn't come close to passing the old professional standard.
The risk for you as a buyer: you feel as safe in your AAA textile jacket as in a race suit. But good leather can be much more abrasion-resistant than many textile fabrics. The standard puts both in the same class (AAA) and so suggests an equivalence that doesn't exist.
5. Seams and zones: the underestimated construction
What good is the best fabric if the seam opens like a zip? The standard divides clothing into zones:
Zone 1: shoulders, elbows, hips, knees. The material is strongest here.
Zone 2: for example arms, back, seat and outer sides of the legs.
Zone 3: less exposed areas such as chest, stomach and the insides of arms and legs.
Manufacturers save by using thinner material in zone 3. But in a highside, when you're thrown through the air, it's pure chance which part hits first. If you land on the inside of your upper arm (zone 3), the CE certification only helps to a limited extent.
Then there's shifting. In the lab the fabric sample is firmly clamped. In real life the jacket may be a size too big. On impact the sleeve rides up, the protector twists away and the skin grinds over the ground. No certification can enforce a good fit.
6. Why the CE standard still matters
For all the criticism: the CE standard is the best thing that could have happened to the market. For three reasons:
Less junk: it has pushed out products that offered practically no protection, such as simple cotton hoodies without aramid reinforcement.
Control of chemicals: via the general PPE requirements (EN ISO 13688), limits are checked for substances such as chromium VI in leather, which can trigger serious allergies on contact with sweat.
Comparability: it forces manufacturers to put money into development, not just design.
7. What to really look for when buying a motorcycle jacket
Next time you're in the shop, don't just look at the CE label. This checklist helps:
Feel of the material: does the textile feel very thin and soft? Then it's probably only class A or AA. For touring and motorways it should be AAA or very sturdy AA.
Armour pockets: try to move the protector in the jacket by hand. If it can be pushed away from the tip of the elbow without effort, it won't protect you in a crash.
Double seams: check whether the seams are concealed. Exposed seams are cut through immediately when sliding.
Leather: if you want maximum safety, you can't get around leather. No textile (except perhaps very expensive Superfabric or special full aramid fabrics) matches the protective properties of cowhide.
Airbag systems: if you want to raise your level of protection significantly, buy an airbag vest. Airbags are tested to EN 1621-4 and, depending on the system, cover the back, chest and partly the neck and hips over a large area.
Summary
The CE tests for motorcycle clothing are a necessary minimum, but they don't reproduce a real crash. A "pass" in the lab only means you won't be left without protection the moment you first touch the ground.
Real safety only comes when material, fit and modern technology such as an airbag work together. Anyone who thinks they're invulnerable in a cheap 150-euro AAA textile jacket is fooling themselves. The road tests harder than any lab.
Frequently asked questions
What exactly does "CE" on my motorcycle jacket mean?
CE stands for Conformité européenne. It isn't a quality seal in the classic sense but the legal proof that the product meets the EU safety requirements for personal protective equipment (PPE). Without this label, a motorcycle jacket may not be sold as protective clothing in the EU.
Is class AAA always better than AA?
For abrasion resistance, yes. AAA offers the highest protection against wearing through at high speed. But AAA clothing is often heavier and stiffer. For pure city riding a flexible AA pair of trousers can therefore be the better choice, because thanks to the greater comfort you'll actually wear it.
Why do leather suits usually last longer than textile jackets, even though both are AAA?
The standard only sets a minimum requirement for AAA. Many textiles only just meet that limit, while good leather is often well above it. The class is open at the top, and physically leather plays in a different league.
Is a level 1 protector enough?
Level 1 is the basic certification. Level 2 reduces the transmitted force much more (on average under 20 kN instead of under 35 kN for joint protectors, for the back under 9 kN instead of 18 kN). For spine and joints you should go for level 2 if possible.
Can I rely on the abrasion resistance of motorcycle jeans?
Only if they're CE-certified. Normal jeans last less than a second in the abrasion test. Certified motorcycle jeans (class A or AA) use aramid fibres (Kevlar) or Cordura and so manage several seconds of sliding time.
What happens to protective clothing in the rain?
Wet can change the friction values. More important, though: soaked fabric gets heavier and the protectors shift more easily. Your body also cools down, which significantly reduces concentration and therefore safety.
Why are protectors only tested with 50 joules in the lab?
50 joules correspond roughly to a 5 kg weight falling from a height of one metre. That sounds like little, but it's a standardised comparison value. Real crash energies are often higher. The lab is about making the damping of materials comparable.
Does my clothing also protect against broken bones?
Only to a limited extent. Protectors protect against comminuted fractures and direct blows to the joint heads. They hardly prevent fractures caused by twisting (torsion) or severe overextension.
How can I tell whether a protector is really certified?
The protector itself must be permanently embossed or printed with the pictogram of a motorcyclist, the standard number (e.g. EN 1621-1) and the level (1 or 2).
Does textile clothing really melt into the skin?
Yes, if it's made of simple polyester or nylon and there's no protective layer such as aramid underneath. The frictional heat when sliding can liquefy the plastic, leading to burns that are hard to treat.
How long does a protector last?
Many manufacturers recommend replacing it after a few years, often around 5 years is mentioned. Plastic and damping foam can harden or become brittle over time, and then the protective effect decreases.
What is the "Darmstadt machine"?
It's the current test device for EN 17092. It brings fabric samples up to test speed and drops them onto a concrete surface to simulate abrasion. Critics consider it less realistic than the old "Cambridge machine", which worked with an abrasive belt.
Are airbag vests covered by the CE standard?
There's a separate standard for airbags (EN 1621-4) with level 1 and level 2. Among other things, the damping and how fast the airbag inflates are tested. Because it covers large areas, it counts as one of the most effective additions to normal protective clothing.
Why are some parts of the jacket thinner than others?
The standard divides clothing into zones. In areas that touch the ground less often (e.g. the inside of the arms), manufacturers use thinner fabrics for better ventilation and more freedom of movement.
Do I have to throw my clothing away after a crash?
Textile clothing is almost always single-use: after a slide the fibres are destroyed by heat and abrasion. Leather can often be repaired by a specialist as long as seams and material thickness are still fine. Always replace protectors after a hard impact.
