Summary of a 10,000-word long article: How to match a King Kong helmet that suits you?
Preface: Certain helmet brands or models are more popular among riders in the market. Many friends have heard that “this one is better and suitable for you”, which leads to many riders having a preconceived idea when buying a helmet, thinking that this model is good, I want to buy this, and if I buy another one, will I seem unprofessional?
Actually, it is not. Everyone has a different head shape. What suits his head shape may not suit yours. In addition, the aesthetics of prints are also very personal, just like shoes and clothes. You definitely don’t want to run into someone wearing the same clothes or shoes as you when you go out. The same goes for helmets. If there are several people in a team wearing the same helmet as yours, then even the most beautiful print will look ordinary.
So when buying a helmet, don’t blindly believe that a certain brand is good or follow the crowd. First of all, you have to make sure it suits your head shape (you can try it on if it’s better), and then choose according to your budget, aesthetic taste and favorite brands.
The following is the text
Helmet, an equipment that a knight is very familiar with.
As the most basic equipment for riding, a good helmet is the basis of safe riding and can increase the survival rate in accidents. As long as you ride, you must wear a helmet, whether you are commuting in the city or traveling around the world. Wearing a helmet is not only responsible for your own safety, but also the most basic principle as a rider.
It’s hard to imagine what would happen if the owner of this picture didn’t wear a helmet…
However, there are many brands of helmets on the market now, and the quality is uneven. The safety of unknown brand helmets is not guaranteed. How to choose a suitable helmet is the first problem that every novice rider faces.
This article will introduce the types, materials, and selection of helmets. It is quite long, so you can choose to read it. The specific directory is as follows

1. What types of motorcycle helmets are there?
At present, motorcycle helmets mainly include full helmets, half helmets, and 3/4 helmets .
Full-face helmet : It has perfect protection performance, the best wrapping among all types of helmets, the highest safety, and the lining can also play a certain role in noise reduction. But the disadvantages are lack of ventilation, stuffiness, narrow field of vision, and not very friendly to people wearing glasses.
Half helmet: From the shape, it can be seen that the half helmet lacks protection for the chin and the back of the head. It has a low production cost and is relatively unsafe. It is not allowed to be used in some countries and regions. It is more common among people who ride pedals and electric vehicles in China.
3/4 helmet: also called retro helmet, air force helmet, similar to a full-face helmet without a chin, looks more stylish, has good ventilation, is more comfortable to wear in summer, and is more suitable for people who wear glasses. The disadvantage is that the wind noise is relatively loud, and the chin is not protected and is easily injured. Some have windshield lenses, while others do not. Those without windshields require glasses to protect the safety of the eyes.
The full face helmet above is called a Fullface full face helmet , but there are actually three other categories of full face helmets:
Offroad helmet: As the name suggests, it is a helmet used for motorcycle off-road sports. It has enhanced chin protection and a protruding brim on the forehead to block sunlight and dust, and also prevent obstacles such as branches from entering the eyes. The disadvantage is that there is no windshield lens, so you need to wear goggles yourself, and the wind resistance is large, so it is not suitable for high-speed driving.
Tour-cross rally helmet: Rally helmet combines the advantages of full-face helmet and off-road helmet, the windshield lens is detachable, and the chin design is more restrained than that of off-road helmet. It is safer, but the wind noise and wind resistance are relatively large, so it is not suitable for high-speed driving.
Flip-up helmet: The chin device of a flip-up helmet can be lifted up to become a 3/4 helmet, and it can be lowered to become a full-face helmet. The advantage is that it can be lifted up for ventilation, drinking water, eating, etc., but since it is not an integrated helmet and the chin is detachable, the wind noise control and protection are not as good as full-face helmets.
Different types of helmets are suitable for different riding scenarios. For example, off-road helmets are used for off-road riding, rally helmets are suitable for people who have both long-distance and off-road needs, full-face helmets are suitable for tracks and daily riding, and 3/4 helmets and flip-up helmets are suitable for daily riding. In addition to your own needs, you should also choose a helmet that matches your model, which will look better overall.
Overall safety: full face helmet > 3/4 helmet > half helmet
2. The basic structure of motorcycle helmets
The structure of a motorcycle helmet mainly consists of a shell, a buffer layer, a lining, a wearing device, goggles, a jaw guard, etc.
case
The shell is the first line of defense for head protection and the main structure of the helmet, so the shell must be made of high-strength and impact-toughness materials to absorb impact energy without causing excessive deformation. According to the strength of the material, it can be divided into Kevlar fiber> carbon fiber> glass fiber> ABS plastic .
Buffer layer
The buffer layer usually works together with the shell to disperse the impact force. It can relieve the impact force transmitted from the shell and protect the head. The buffer layer is usually made of foamed polystyrene . After an accident, although the shell surface is not seriously damaged, the internal buffer layer material has actually been damaged. Therefore, even if the outer surface of the helmet does not seem to be damaged, it is recommended to replace the helmet.
Lining
The lining layer is mainly used to increase comfort, and is generally made of soft flannel to fill the gap between the head and the helmet. The lining is usually in direct contact with the face, and can be required to be ventilated and sweat-absorbent, and at the same time removable for easy cleaning in the future.
Wearing device
Nowadays, the straps are generally designed to be firm, reliable, and easy to unfasten. There are mainly several types of fastening methods, such as snap-on, patch, and ring. Among them, the double D ring is considered to be the safest tightening system.
Goggles
The windshield lens mainly protects the eyes and face. In addition, it is also required to have a certain light transmittance (greater than 85%) and meet a certain impact strength to ensure that it will not interfere with the driver’s field of vision and avoid the lens from breaking and thus hurting the eyes and face. The materials include plastics (such as polycarbonate resins) and reinforced glass sheets (such as PMMA resins).
Protect the jaw
The jaw guard is a component of a full-face helmet, which has an additional part to protect the lips and jaw. In the event of an accident, it can provide more protection for the chin and face.
3. Which shell material is best?
As for the motorcycle helmets currently on the market, the shell materials include PP material, ABS material, ABS+PC, fiberglass (also called fiberglass), carbon fiber, and Kevlar fiber. Among them, helmets made of ABS and ABS+PC materials account for more than 90% of the market share. Helmets made of fiber materials are more expensive because of the expensive raw materials, complex production process, and high labor costs . Among these fibers, Kevlar fiber is the most expensive, lighter in weight, but stronger than steel. It should be noted that if you see PP material, you can ignore it directly. PP material is used to make toys, so don’t buy it.
From the material point of view, strength: Kevlar fiber > carbon fiber > glass fiber > ABS+PC > ABS > PP
Since helmets made of fiber material are so much more expensive than those made of ABS material, does it necessarily follow that helmets made of carbon fiber material are safer than those made of ABS material?
The answer is no . This is a misunderstanding of many people: high material strength does not necessarily mean high safety.
The main difference between ABS and fiber helmet shells is that ABS is easy to break under strong impact, while fiber is not easy to break. It is difficult to say which material is the best for the helmet shell based on the shell material alone. A motorcycle helmet must pass the safety standards of various countries or be tested by a third-party organization to ensure its safety. If the same model of helmets made of different materials (carbon fiber, ABS) get the same score in a certain crash test, then the two materials are equally safe.
In addition, the manufacturing process, thickness, density of the EPS material of the buffer layer and the design of the helmet will all affect the safety of the helmet, and the safety of the helmet cannot be judged solely by the material of the shell.
Of course, in some large motorcycle events (such as MOTOGP ), composite fiber helmets are still used. After all, the speed is very fast, and the helmets are certified for related events. But for our daily riding, there is not much difference between composite fiber and ABS materials. It depends more on the price, brand, quality, etc. of the helmet. It is best not to buy a helmet that is too cheap, as it is very unsafe. For novices, it is better to choose a helmet that costs more than 60 dollar.
Let me add one more thing here. As we all know, carbon fiber is only one color in China (joking). Those carbon fiber with a price tag of several hundred are basically fake. If you want to buy a carbon fiber helmet, you need to carefully distinguish whether it is real carbon fiber.
4. What are the safety certifications for motorcycle helmets?
On the back of the helmet, you can usually see words such as ” DOT , ECE , CCC, SHARP, SNELL …” These are the safety certifications of the helmets. Each country has a safety certification standard for helmets, and only when they meet this standard are they allowed to be sold in the country.
1. DOT Standards
DOT is the U.S. helmet certification standard. DOT is generally divided into three levels: A, B, and C. Level C is the lowest standard. It is certified independently by the manufacturer. After it is put on the market, only random inspections are conducted. If it fails to meet the standards, the entire product will be recalled.
It should be noted that although some helmets sold in China are affixed with the DOT label, they are not subject to market supervision in the United States, and may be affixed without being tested at all. Therefore, when buying American helmets in China, it is recommended to buy those with 3C certification .
2. ECE Standards
ECE is the European Economic Commission certification, and 2205 specifically refers to the part of the agreement that specifies the helmet testing standards. It includes tests on initial impact force, stiffness, friction, and strap strength.
3. GB Standard
This is China’s certification standard, also known as 3C certification. The technical standards based on 3C certification are implemented according to GB standards. Domestic standards are actually not lower than those of DOT, ECE and other standards, but there are some differences in the test items. The quality of products applying for 3C must meet the requirements of national standards. Only those that have obtained 3C standards can be affixed with the 3C logo, and they must be affixed with this logo before they can be sold in the domestic market.
4. SNELL Standard
This standard originated from an American racing driver named William Pete Snell who died from a severe head injury during a race. His friend founded a foundation called SNELL to focus on researching and developing helmets that can protect the human head. This standard has a certain influence in the industry. It is updated at least every five years based on new research results and existing technologies. The latest standard is SNELL M2020. Although SNELL is not a legal standard, helmet manufacturers are willing to spend a high price to send their helmets to SNELL for testing, because the word SNELL printed on the helmet is a guarantee of confidence.
5. SHARP Standard
Sharp is a British standard. To obtain a rating, the helmet must pass at least 32 tests. The final rating of the helmet is based on the test results, with 5 stars as the highest and 1 star as the lowest. The difference in protection performance between high-scoring and low-scoring helmets can even reach 70%.
6. FRHPhe standard
This is a brand new, modern motorcycle helmet testing standard released by the International Motorcycling Federation (FIM). This standard is currently the most difficult standard to pass in the world, bar none.
7. SG, JIS, MFJ standards
These three are domestic standards in Japan, which are not well known. If you want to participate in domestic competitions in Japan, you must wear a helmet with MFJ certification.
There are basically several common helmet certification standards. Although the testing methods of different standards are different, they are all similar. They are completely sufficient for driving on ordinary roads. There will be no problem buying a 3C certified helmet in China . It is better to carry strict standards with you, but it is more important to buy a helmet that suits you. If it does not fit your head shape, no matter how good the certification is, it will be useless.
Attached are some test specifications for each certification standard:
5. How to choose a motorcycle helmet that suits you
After reading so much, most of you may still not know how to choose a helmet that suits you. After all, who doesn’t know that expensive things are good? But the key is that it is expensive! The best thing is to buy one that suits you within your budget.
1. Purchase according to riding scenarios and models
If you are going off-road, then buy an off-road helmet. If you want to go long distances and go off-road, then buy a rally helmet. For regular road riding, you can buy a full-face helmet or a 3/4 helmet. In addition, it is also important to match the helmet with the model of the car. Otherwise, buying a purple helmet with a completely black body? It doesn’t look harmonious, right?
2. Choose the helmet size that suits you
If conditions permit, it is best to go to a nearby physical store to try it out. Different brands of helmets are suitable for different head shapes, so there may be a situation where they do not fit well. It should not be too tight or too loose. If it is too tight, it will not be comfortable, and if it is too loose, it will be unsafe when it is hit. The most direct feeling after putting on a suitable helmet is
After putting on the helmet, I shook my head left and right, up and down, but the helmet did not move.
It feels a little tight, and the facial muscles are lifted by the lining
Grit your teeth so your temples don’t hit the helmet
If these three feelings are met, then the size of the helmet is just right. If there is no physical store, or the physical store does not have a helmet that fits your needs, then you can only buy it online. You need to measure your head circumference first. The measurement method is to use a circumference ruler to circle around the protruding points of the forehead and the bulge of the back of the head, as shown in the picture. In addition, when purchasing, it should be slightly larger than your own measurement data by 2-3cm for the most comfortable wearing.
3. See what kind of head shape you have
There are three main types of helmet head shapes on the market: long oval (more common in Europe and the United States), intermediate oval (more common in North America and China), and round oval (more common in Asians). However, not all domestic riders have round oval heads. Head shape is not only related to genes, but also to later formation. Therefore, you should buy a suitable one according to your head shape. Not necessarily a round oval helmet from a Japanese brand is suitable for domestic riders. It is best to try helmets of various head shapes to see which one suits you.
4. Look at your budget and preferences
Your budget determines how good a helmet you can buy. For beginners, it is recommended to choose ABS helmets above 400 yuan. Helmets above 1500 yuan or 3000 yuan are mostly made of fiberglass or carbon fiber, which are suitable for friends with sufficient budget. In addition, whether to buy a full-face helmet, a 3/4 helmet, or a flip-up helmet, which brand you like, and which prints can hit your aesthetic point are all based on personal preference.
5. Other aspects to consider
Some of this has been mentioned before, but I want to emphasize it again.
You should buy products with safety certification. In China, it is not recommended to buy products with only DOT certification. At least 3C or 3C+DOT certification is required , because the DOT certification in China is not very strict. For other certification standards, only one is enough.
Don’t buy a PP shell, at least ABS material, high speed can choose fiberglass
The density of the foam material of the buffer layer should be high. If there is a hole when poking with a finger, it is unqualified.
The weight should be light, no more than 2kg
The lining of a full-face helmet should have eyelets, mesh and ventilation design to achieve the effect of sweat absorption and ventilation.
The lens is clear and has no color difference. When wearing the helmet, the vision is not blocked and the surrounding sounds can be heard clearly.
6. Selection of cost-effective helmets at different prices and brands
Your budget and whether the helmet is suitable are the most important. On this basis, consider the print and the brand you like. Here are some common domestic and foreign brands of motorcycle helmets, which can be used as a reference when choosing.
According to different helmet types and different price ranges, some brands with high cost performance are selected.
Helmet types are divided into full-face helmets, flip-up helmets, rally helmets, off-road helmets, and 3/4 helmets for recommendation (half-face helmets are not very meaningful)
The prices are classified into the following ranges : 50-150, 150-200, 200-300, and above 300.

SHOEI is a very famous helmet brand in Japan, and its helmets are of the same level as AGV.
The main feature of Z7 is lightweight, and it is a sub-top track/receive helmet. Although the appearance is not so sharp, it wins in terms of quality, close-fitting lenses, and waterproof air ducts. The switches of the mouth, top box, and eyebrow air ducts are very delicate, and the lining is also very soft and comfortable, which is a typical SHOEI style.
The design of the ventilation system is also very good. When the lower jaw air duct is opened, the air immediately flows from bottom to top, passing through the lens and blowing into the upper air duct. The disadvantage is that the noise control is not very good.
If you want better noise reduction, you can choose the new Z8, which is a few hundred dollars more expensive, but the noise reduction is much better.
ARAI RX-7X
Material: Super Fiber PB-SNC²
Certification: SNELL+3C
Weight: 1500g±50g
ARAI is also a very famous helmet brand in Japan, and is considered to be one of the top three helmet manufacturers in the world, along with AGV and SHOEI. RX7X is a top track helmet, characterized by low wind noise and a rounded helmet body.
The shell is made of the latest super fiber with higher fiber density. Compared with the usual glass fiber, it is 40% higher in tensile and compressive strength than glass fiber.
The helmet uses the VAS variable axis lens system for the first time, which makes it easier to remove and install the lens without tools. Most Japanese and European helmets on the market now have exaggerated spoiler designs such as big ducktails, but the RX7X maintains the ancient cone lines of the antique helmet, with a shell radius of no more than 75mm, creating an easy-to-roll arc to reduce impact force.
The ventilation duct adopts a new switch design and the noise control is also very good.

LS2 FF370——$60 price
Material: ABS
Certification: SHARP four stars + 3C
Weight: 1550g ± 50g
This is a very cost-effective flip-up helmet from LS2. It has double lenses, anti-fog and anti-scratch windshield lenses, a sun visor and Bluetooth functions. The weight is also within an acceptable range, and the cost-effectiveness is very good.
MT ATOM——120$ price
Material: Polycarbonate
Certification: SHARP 3 stars + 3C
Weight: 1600g ± 50g
MT only has this one flip-up helmet, ATOM. As an overseas brand, the price is indeed quite affordable. The shell is made of polycarbonate and the helmet has multiple exhaust ports and spoilers, so the breathability is still very good.
LS2 FF394——210$ price
Material: Carbon fiber
Certification: 3C
Weight: 1350g
Because of the splicing design, the flip-up helmet is generally heavier than the full-face helmet. The LS2 FF394 uses a carbon fiber helmet body, which is safer and lighter, making it suitable for long-distance riding. This is why it is so expensive.
3. Off-road helmet/rally helmet
FASEED FS-909

The brim is removable, with double-layer lenses and a built-in lens switch, which makes it more convenient to use. It also has a 180° wide viewing angle, a blue earphone slot, and 5 vents. The ventilation is also relatively good. It is a good rally helmet at this price.
4. 3/4 Helmet
The advantages of 3/4 helmets are that they are cooler, less wrapping, and lighter, making them more suitable for summer wear. At the same time, their prices are much lower than full-face helmets. However, they are definitely not as safe as full-face helmets. It is recommended that they have at least 3C certification, which guarantees more safety.
LS2 OF508
Material: ABS
Certification: 3C
Weight: 1100g
A 3/4 helmet under 200 yuan with 3C certification is enough for general electric and pedal bikes. Although it is a 3/4 helmet, this LS2 is also equipped with a ventilation system, which is more breathable, and the lining is also removable and washable. It is not safe or cost-effective, but it is enough for commuting to work.
AMZ
Material: ABS
Certification: 3C, DOT, ECE
Weight: 900g
A very retro 3/4 helmet, the outer shell is made of fiberglass, and there is also an EPS inner helmet. The safety is relatively high among 3/4 helmets. The lens adopts a built-in design, and the windshield lens can be pushed up and down, which is quite convenient. A 3/4 helmet with a very high cost performance!
If you want something cooler, you can take a look at the following one
BELL ROGUE HELMET
Material: Glass composite fiber
Certification: 3C, DOT
Weight: /
Bell is an authentic American brand. Although it is not a brand that specializes in helmets, its professionalism in the field of helmets is not diminished at all. The mask of this model is adjustable, so you don’t have to worry about it not fitting. The fiberglass shell and 3C certification are also safe enough. You can check whether this helmet matches your car or daily outfit. If it doesn’t match, there is no need to buy it.
Another type is the half helmet. I personally do not recommend buying a half helmet because it is less safe. Besides, a 3/4 helmet is much more stylish and breathable than a half helmet. After all, a helmet is mostly a decoration, and appearance is also an aspect that needs to be considered. If you must buy a half helmet, remember to buy one that is 3C certified.
VII. Some Common Questions
1. Do I need to buy a new helmet if it is damaged?
According to the test results of many manufacturers, if the helmet is dropped, the EPS material of the cushioning layer will be damaged, thus reducing safety. However, it also depends on the speed of the drop and the degree of damage. If it is just a slight drop, it is generally fine. If it falls from a height of more than 1m and the helmet has cracks, it is recommended to buy a new one.
2. Is the more expensive the helmet, the better?
No, the price of a helmet is related to market demand, production process, etc. The price is not determined solely by the level of safety. Most of the time, a helmet is just a decoration, and safety only works in the few seconds after a collision. Therefore, the more beautiful the design of a helmet is and the more complicated the production process is, the higher the cost and the higher the price will be, but the safety may not be much different.
3. Can I buy a helmet in a larger size?
It is not recommended to buy a helmet that is one size larger for comfort. First, in the event of an accident or collision, an inappropriate helmet can easily fall off, which is very dangerous. Second, a helmet that is one size larger can easily cause a secondary collision during a collision, increasing the possibility of head injury. Therefore, for your own safety, it is recommended to buy a helmet that fits your head shape.
4. Does a helmet have a shelf life?
Most manufacturers recommend replacing helmets every five years, regardless of whether they have been damaged or not.
