Comparison MT Targo vs LS2 FF353 Rapid

The sizes in which this helmet model is produced.

The appropriate helmet size depends primarily on the circumference of the wearer's head. The circumference is measured at the widest point of the head — usually at a level of 1 – 2 cm above the eyebrows and along the protrusion at the back of the head; more detailed recommendations and descriptions can be found in special sources. Here we note that although manufacturers use the same size designations — XXS, XS, S, M, L, XL, etc. — specific sizes for different brands may vary slightly; for example, XL can fit both 60 – 61 cm and 61 – 62 cm. This seemingly small difference can significantly affect the comfort and safety of use. Therefore, when choosing, you need to be guided by the size tables of a particular manufacturer.

It is also worth considering that helmets with the same size designation may differ not only in actual size, but also in the shape of the internal space. Therefore, even compliance with the size table is not a guarantee that the product will be suitable; the most reliable way is to test the helmet "live" before buying.

A type of fastener used on a motorcycle helmet to secure a chinstrap.

— D-Rings. A classic clasp that is still popular today due to its combination of simplicity and reliability. The basis of the design is a pair of D-shaped rings (hence the name). When properly applied, these rings firmly clamp the belt passed through them, and the free end of the belt is fixed to the clasp-button or magnet. In addition to a secure hold, the advantages of D-Rings include the fact that size adjustment is made on the fly every time, directly when fastening; this is especially convenient for a "passenger" helmet, which has to be used by different people. On the other hand, the fastening-unfastening process itself is not very convenient: it requires a certain habit and takes more time than in other fasteners.

— Quick click. The classic Quick-Click design resembles a car seat belt buckle: on one half there is a metal plate with a hole, on the other there is a lock that automatically fixes this plate and opens at the touch of a button. It is believed that such fasteners are less reliable than D-Rings, however, with proper workmanship, this difference is not significant; and fasten and unfasten Quick-Click much faster and more convenient. Also in this category are "fastex" — fasteners, familiar to many from tourist equipment. "Fastex" has the form of a trident, fixed in a special nest, such a lock opens by...pressing from the sides; this variety has not received much distribution, as it is considered not very reliable.

— Ratchet. Also known as Quick-Release. One half of such a clasp looks like a strap (usually plastic) with a special notch, a lock is installed on the second. The strap can move through the closed lock only in one direction — to tighten, this is how the “ratchet” fastens (with a characteristic sound, hence the name). To unfasten it, you need to open the lock, giving the strap the opportunity to move in the opposite direction. This design allows you to quickly and easily remove and put on the helmet, while, like the D-Rings, it automatically adjusts to size with each fastening. At the same time, fasteners are considered not very reliable, but in fact it all depends on the quality of workmanship (which, usually, is directly related to the price category of the helmet).

— Quick release visor. The ability to quickly remove the helmet visor, in most cases without the use of special tools. Such an opportunity can be useful, for example, for cleaning from pollution, replacing transparent glass with tinted glass, or vice versa.

— Anti-fog coating. The presence on the helmet visor of a special coating that prevents fogging from the breath of a motorcyclist. This feature will be useful especially in cold weather (glasses practically do not sweat at high air temperatures). It is especially important for closed helmets (integral and enduro, see "Type"), but can also be found in open ones. Note that such a coating is not a 100% guarantee against fogging, but the likelihood of this phenomenon is greatly reduced.

— Sun visor. A sunscreen in the form of additional tinted glasses that can be lowered and raised as needed, usually by means of a small lever or button on the side of the helmet. Do not confuse this device with tinted glass (see "Visor" above): a sun visor is provided as an addition to the main visor and covers only the eyes. By lowering and raising such glasses, you can “turn on” and “turn off” additional dimming. At the same time, the main visor is most often made transparent, thanks to which the helmet can be comfortably used at night — just lift the built-in glasses and look through the transparent glass. However,...the sun visor can also be combined with tinted glass; this option will be appreciated by people with sensitive eyes that do not tolerate sunlight well and require enhanced darkening. The disadvantage of this feature is a noticeable increase in the cost of the helmet.

— UV protection. Availability of UV protection in the glass and/or helmet sun visor (see above). Intense ultraviolet light is harmful to the eyes, it leads to their rapid fatigue, deterioration of vision, and sometimes even eye diseases. Moreover, such radiation can be quite intense not only in sunny, but even in cloudy weather; in addition, the amount of ultraviolet increases in mountainous areas as altitude increases. However with short-term exposure, the described effects are hardly noticeable, but even for trips over short distances, UV protection will be useful. And if you are going to travel "far and long" — this feature is highly desirable. Note that if necessary, UV protection can be provided using separate glasses (motorcycle or conventional), but not all helmets allow the use of such glasses.

— Built-in ventilation. The ventilation system usually has the form of holes in the shell — the air flow entering them "blows" the inside of the helmet. This not only provides comfort (especially in hot weather), but also reduces the amount of moisture accumulating inside: the rider's head sweats less than in a fully closed helmet, and the sweat that is released quickly evaporates and is blown into the ventilation. At the same time, many models provide the ability to completely or partially block the ventilation — for example, in cold or rainy weather.

— Breath cutter. Most often found in helmets of a closed design (integrals, modulars, enduro — see "Type"). In such models, it is a kind of visor that covers the nose and mouth of the motorcyclist — so that the exhaled air is discharged into the lower part of the helmet and the visor does not fog up. Also, sometimes cut-offs are called additional masks that are equipped with open helmets, but this is not entirely true — such masks have a slightly different purpose, they are mainly designed to protect the mouth and nose from dust, small litter, insects, etc.

The results shown by this helmet model in the SHARP safety rating.

SHARP is a comprehensive testing methodology designed to determine the degree of protection and safety level when using a helmet. Each helmet is tested for direct (linear) impact as well as glide impact friction; in the first case, the acceleration acting on the motorcyclist's brain is measured, in the second, the twisting force acting on the neck is also measured. Tests are conducted for different points of impact, each test involves a minimum of 32 test collisions (more if necessary). The data obtained is compared with information about real injuries, and based on this, the helmet is rated on a five-point scale — from 1 to 5 stars.

The higher the SHARP rating, the safer the helmet and the lower the chance of serious injury while wearing it. However, when choosing this parameter, it is worth considering some nuances. First, the SHARP check is only done on models sold in the UK; and therefore the absence of such certification does not mean poor protection — it may indicate that the helmet simply did not make it to the test. Secondly, the cost of a helmet practically does not affect the number of stars: neither 5 stars for a low-cost model, nor 2-3 stars for a top one are rare. Thirdly, the SHARP programme only checks safety in collisions, it does not affect issues of convenience, aerodynamics, visibility, etc. And even the SHARP experts themselves recommend choosing the most conveni...ent models first, and only then choosing the option with the highest number of stars.

Safety certification or certifications to which the helmet conforms. To date, the following types of certificates are found in motorcycle helmets:

—ECE 22.05. The European certification system, which provides for very strict requirements for safety testing among national and international standards (except that in the ACU the requirements can be even tougher). According to ECE 22.05, each batch of helmets must be tested before being sent for sale (for this, several test items are selected), and the testing itself is quite strict and takes into account the fact that motorcyclists' heads can have different sizes and weights. Helmets certified according to this standard are used even in professional motorsport (although, of course, products of different levels and purposes can pass certification).

— Snell. Also known as SMF. Standard developed and used in the USA; appeared in the mid-1950s, and has been regularly improved and refined since then. Snell's requirements are more relaxed than ECE 22.05, but tougher than DOT: products must undergo constant quality control, and the test takes into account the possible difference in head size (although it does not take into account the difference in weight).

— DOT. The standard was developed by the US Department of Transportation back in 1972 and has remained virtually unchanged since then. It provides for very mild conditions for b...oth the testing itself and the control of the results. So, the check is carried out only for the standard size and weight of the head, the manufacturer himself does this and he also determines whether his products comply with DOT requirements, and control by the Ministry of Transport is limited to periodic selective testing. However, even with this in mind, having a DOT is much preferable to no certification at all.

— ACU. A standard developed and maintained by the British Motorcycle Union (Auto-Cycle Union), a public organization representing the interests of the motorcycle community. Provides two main marking options — ACU Gold and ACU Silver; however, the second option is extremely rare for a number of reasons, and it is usually the top, “gold” marking that is used. In order to be ACU Gold certified, a helmet must not only meet certain generally accepted standards (described above by Snell 2005 or ECE 22.05, British BSI Type A, etc.), but also be tested according to ACU rules, which require additional checks. As a result, the ACU Gold marking corresponds to a very high level of safety. Note that some time ago this system was at the centre of a scandal: there were rumors that “ACU Gold” stickers are sold freely and can be found even on low-quality helmets that have not passed (and are not able to pass) an official test. However, the ACU organization has taken steps to correct the situation, and conscientious sellers do not go for such a deception. However, if you have any doubts, you can check from official sources (for example, the ACU website on the Internet) whether the selected helmet meets the safety level claimed for it.
