How to choose the correct helmet size?

Much of the effectiveness of a helmet depends on the correct selection made of it, especially its size and correct fit. A loose helmet can come off in an accident, and one that is too tight can cause undue discomfort to the wearer. Speedoz Ltd provide the best quality helmets in Bangladesh with an affordable price. As there is no helmet that works for all motorcyclists, it is very important to try on different models and brands before making the purchase. Here is a simple guide to follow to make a good selection when making the purchase:

Once you have it on, check that it does not squeeze you too much, if because of excessive pressure it causes pain in any part, you should go to a size more or another helmet model. It is recommended that the frontal foam press the cheekbones, since use, sweat and wind pressure cause it to deform and lose its consistency.


In case it does not tighten, check that it is not loose, for this try inserting a finger through the front or the back, if your finger enters easily, the helmet may be large and you need to try another size.


Check that the helmet is perfectly attached to the head. With both hands, move the helmet alternately trying to keep the sight in front, the helmet should rotate together with the head without causing a game between both.


Fasten the buckle and adjust it to your needs so that it does not become loose and does not drown you. As there are different types of buckles, if you do not know the one you are trying, ask for help to fasten it and adjust it correctly.


With the straps fastened and adjusted it proves that the helmet does not come off. Take the helmet with both hands from the back and try to remove it. If it comes off, you should look for another size or model.

Helmet types

Different types of helmets are marketed in the market, among these we can find:
1.- Open helmets
They are those that do not have protection on the jaw, the security they provide varies according to the model, among their varieties you can recognize the following types:

HELMET-JETJet helmet
It is the safest of this type, it has protection for the neck and ears. Some models have mica (screen) for protection of the sight, this can be foldable.

SEMI JET HELMETSemi Jet Helmet
Reduces the level of protection compared to the previous one, leaves the nape of the neck uncovered. In the same way as in the previous case, you can have mica.
PRUSSIAN OR GERMAN HELMETPrussian or German helmet
It is the version that protects the least, it does not have mica or protection for the neck and ears.

2.- Integral helmet
FULL HELMETThis helmet is considered the safest, since a single piece completely covers the head protecting it in its entirety, it even covers the jaw of the biker. Most of the cases have a mica or protective screen for the view.

3.- Modular or Convertible Helmet
MODULAR OR CONVERTIBLE HELMETIt is an alternative to the full face helmet, it presents greater comfort than this in the city since at lower speeds the front part can be folded down. But its safety is somewhat diminished by having a pivot mechanism on the side.

Helmet certification

Helmet certification is strictly a measurement of how a helmet reacts during an event to protect the wearer's brain, they are tests that are designed to be repeatable, quantifiable and include a fixed range of reasonable situations that a helmet could be subjected to such such as: Impact attenuation; Penetration; Restraint system; Conditioning (environmental condition; high temperature, low temperature and immersion in water) and labeling requirements.

What are the certification standards accepted by our traffic law?

In our country, according to the current standard (Dec.231 / 2000 MTT), the only recognized and accepted certifications are the following international standards:

• Standard Nº218, Motorcycle Helmets, established by the United States Code of Federal Regulations. It is usually known by the DOT inscription. It is a set of standards set by the manufacturer who is self-certified based on "honor", this is possible in countries like the USA, where there are strict laws for non-compliance with these standards. DOT are the minimum safety requirements that any motorcycle helmet must meet.

• JIS T 8133, which is the one in force in Japan. The least known in our country, this standard is based on the Industrial Standardization Law, which is a set of standards established by the Japanese government and regulates all areas of industrial standardization.

• EN / 22/04 and subsequent modifications, of the European Community of Nations. Now superseded by ECE / 22.05. It is the most widely used motorcycle helmet certification internationally, required by more than 50 countries around the world. It is stricter than DOT and not all DOT certified helmets will meet ECE 22.05 standards. This is due to differences in certification standards. In this case, a specific sample of the helmet to be marketed is certified.

It should be noted that nationally manufactured helmets must comply with any of the aforementioned certifications and accredit it through a certificate granted by the National Accreditation System of the National Institute of Standardization.

There is a certification that is not recognized in our law is the SNELL. SNELL is a non-profit institution that has its own laboratory and certifies helmets under ISO 17025, Snell is a voluntary certification by manufacturers and is one of the strictest, so much so that it does not certify flip-up helmets. This is why we can find DOT helmets with SNELL or ECE 22.05 and SNELL certification.
