There are so many motorcycle helmets on the market, the prices are different, and the quality is also uneven. Novices will inevitably feel dazzled and don't know how to start.

What you pay for what you pay for is an eternal market law. High prices are not necessarily good quality, but low prices must not have good products. First of all, remember this.

Let me talk about the safety standards of helmets. There are currently three types of safety inspection standards for motorcycle helmets in the world, namely DOT standard, ECE standard and SNELL standard.

The DOT standard is the American helmet inspection standard. DOT is the acronym of the U.S. Department of Transportation. This helmet safety standard is a mandatory market standard. All motorcycle helmets sold in the American market must meet this safety standard before they are allowed to be sold. The inspection standards include three inspection methods: plane, hemisphere, and puncture, which are implemented by relevant departments in the United States. Due to its relatively "old" history, this set of standards is no longer a safety standard for high-end helmets and is relatively backward.

The ECE motorcycle safety inspection standard is currently the main meeting standard for high-end helmets. It is one of the main standards met by helmets produced and sold in the EU market. The safety level is stricter than the DOT standard.

Finally, there is the SNELL safety standard. This standard belongs to the professional level. Many professional helmets worn by professional riders meet this standard, with stricter requirements and higher safety levels.

Let’s talk about the helmet shell. At present, the common helmet shell materials on the market are mainly divided into three types: thermoplastic, fiberglass, and carbon fiber. Thermoplastic is not suitable for making motorcycle helmets and has poor impact resistance. The price is also the cheapest. If you have chosen a helmet, but there is no way to know the material of the shell, it is recommended to give up.

But the material of polycarbonate is also a kind of thermoplastic, its physical properties are better than ordinary thermoplastics, and the price is cheaper, it is often combined with acrylonitrile-butadiene-styrene copolymer, this is The common so-called ABS engineering plastic material, the helmet shell of this material has good impact resistance, and is generally the preferred shell material for middle and low-end helmets.

FRP is the common name for glass fiber. Its physical properties are better and more stable than ABS engineering plastics, and it can withstand the test of time. It is the first material for mid-to-high-end helmets.

Carbon fiber shells are generally combined with aramid Kevlar polymer materials. Carbon fiber materials have good structural strength, and the latter has excellent tensile strength. Therefore, the combination is a perfect match, not only high strength, And the weight is also very light, the only drawback is that it is expensive, usually the combination of materials used in high-end helmets.

The buffer layer is also the main component of the helmet. In a sense, it is because of the buffer layer that prevents your head from being subjected to strong shocks when impacted, which is of great significance.

At present, the cushioning layer of most motorcycle helmets is made of EPS foam material, but there are also some specialties. A good helmet cushioning layer should be composed of double or multilayer EPS foam. The outer layer is hard and the inner layer is soft. Impact has a good absorption effect, and cheap helmets generally only tell you that it is the cushioning layer of EPS foam, and will not tell you that there are several layers, so there is a high probability that it is a single-layer foam.

Let’s talk about the inner lining. Generally, the inner lining does not directly play a protective role. Its function is to perfectly fit the helmet to your head shape, and play a role in fixing and improving comfort. Generally, cheap helmet linings cannot Disassembled, so that in the summer, when the head sweats a lot, the inner lining will soon be soaked, and then the next day you have to continue to wear this helmet that emits an unpleasant smell. It is difficult Clean up sweat stains on the inner lining. A good helmet lining should be detachable. Not only that, even the sponge inside the lining can be removed separately. Although this design has no high-tech content, it will significantly increase the cost of the manufacturer. Therefore, only those who really will Manufacturers whose quality is the first consideration will have such a design.

Let's talk about the size of the helmet, this can also identify whether a helmet is a product of conscience.

Generally speaking, most helmets have only one or two or three shell sizes. The interior is designed to be SM, M, L, XL, 2XL, etc. according to the size of your head. This will significantly save the cost of mold opening, but this First, if your head size is too small, it will share the shell with other helmets with larger head sizes, which is not very coordinated in appearance. Wearing this helmet will make you feel like a mushroom, and The weight of the helmet has also increased, and those larger-sized helmets have to reduce the thickness of the buffer layer because they have to accommodate the same shell, which will cause the problem of insufficient protection strength. A good helmet generally has one size and one shell, and each size has a corresponding size shell, so that weight and protection can be balanced.

Let’s talk about a little bit of common sense. Double D buckles are the best for the helmet straps. The straps of this structure can withstand greater tension. Although various quick-release straps are convenient and convenient, they are less strong and extreme. Under the circumstances, it may be unable to bear the pulling force and fall off.

The full helmet has the best protection ability. Although it is not convenient to use, it has the best protection. All kinds of active face helmets, 3/4 helmets and half helmets are not comparable to it. Try to choose a full helmet to provide the best Good protection ability.

The weight of the helmet is very important. An overweight helmet not only indicates that the materials are cheap, but also have poor wearing comfort. Generally, half helmets should not exceed 800 grams, cross-country helmets should generally not exceed 1200 grams, and full helmets should generally not exceed 1500 grams. Pay attention to whether the manufacturer has marked the weight of the helmet. Generally speaking, helmets that dare to mark the helmet weight will not be worse. .
