Helmets can be gathered in various brands depending on its shape, the material used in the manufacture of the exterior shell, its usage, homologation and finally depending on its price. If we look at the shapes, there are three types of shells: the FULL FACE shell, the OPEN FACE (JET type) one and also the MODULAR shell. All of them manufactured in thermoplastic or in composites (fibre). Depending on its own characteristics, helmets will be divided in two brands, those that will be used on the road or those ones that will be used in all off-road riding, as the cross helmets. All NEXX helmets hold ECE 22-05 homologation. Relatively to the prices, as in all products, there are lower prices (plastic helmets) and higher prices (composites - fibre helmets).
To be sold in various countries, the helmet must respect the standard/pattern that those countries impose. There are technical and bureaucratic standards. The homologation is the certification that the helmet itself fulfils the technical standard which the selling country adopted to authorize/allow its sale.
In all Europe countries, the standard in accordance with the rules is ECE 22 regulation of EU (European Union). Nowadays, in its most recent revision, the fifth, it has as abbreviation ECE 22-05. In some countries, namely in Spain and Italy, there are some homologations that have an exclusive national condition for motorcycles with motors of a lower than 50 c.c.. Other homologations, apart from Europe, as the Americans SNELL, DOT, the Japanese JIS or the Australian AS aren\'t recognized as valid in Europe.
The standard ECE obliges that the helmet as a sewed label in the retention strap stating where it was homologated, which is the number of homologation and finally the helmet\'s series number. Only this way may you certificate yourself about the correct homologation of a model that you are about to buy.
No, the label numbers don\'t refer to a specific date. Most of the manufacturers choose an imprint or even another label sewed at the bottom of the external shell.
In order to clean your helmet, you may only use water and soap or another product exclusively recommended by the manufacturer. If your helmet has a completely detachable and washable lining, use exactly the same technique, cleaning the foam left by the soap with clean light water. Let it dry naturally and don\'t twist the pieces.
If your helmet is made of plastic, it isn\'t advisable to paint it. Many of the paints sold in the shops, are made of solvents that might damage your helmet\'s structure. Most of the helmets\' manufacturers use paints made of chemically non-aggressive solvents. The fibre NEXX helmets have no obstacles, in order that you may personalize your helmet.
If your helmet is made of plastic, it isn\'t advisable. Most of the stickers\ manufactures use glue made of solvents, which might damage your helmet\'s structure. In case of fibre NEXX helmets, there are no obstacles, so that you may personalize your helmet.
As soon as the scratches in your visor no longer allow a good vision, you should change your helmet\'s visor. A scratched visor might become dangerous in nocturnal usage, due to the light coming from the others drivers.
Not always a more expensive helmet warrants a greater security. All helmets that respect the ECE 22-05 standard, which is the case of NEXX, has the minimum-security guarantee. The different prices are explained by manufacturers\' peremptory (sponsorships to pilots, for example). Anyway, a fibre helmet will always be safer and more secure than a plastic helmet.
No, the helmets used by pilots are exactly the same as the ones sold at the shops (except for the stickers of its sponsors or the personalization).
