In all European countries, the standard in agreement with the rules is the ECE 22 regulation of EU (European Union). Nowadays, the most recent revision is the ECE 22-05.
There are other homologations, apart from Europe, such as the American SNELL, DOT, the Japanese JIS, the Australian AS and NBR from Brazil that are not recognized or valid in Europe.
To be sold in various countries, the helmet must respect the standard/pattern that those countries require.
The homologation is the certification that the helmet itself fulfils the technical standard which the selling country adopted to authorize/allow its sale.
The standard ECE obliges the helmet to have 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.
As soon as the scratches in the visor no longer allow a good vision it should be changed. A scratched visor might become dangerous in night use.
CLEAN HELMET AND VISOR
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 removable and washable lining, use exactly the same technique. Let it dry naturally and do not twist the pieces.
To clean your helmet visor you may only use a soft cloth, lightly wipe off any grime (e.g. insects, dirt, sand, dust, etc.) from the visor and then fully wipe it clean using dry soft cloth.
When cleaning the visor never use any products based solvents or detergents containing abrasives. To do this operation use only clear water and ph neutral detergent.
USE OF IMPROPER MATERIALS
If the helmet is made of plastic, it is not advisable to paint it. Most of the paints are made of solvents that might damage the helmet's structure.
Measure the circumference of the head by positioning a tape measure in the middle of the forehead, wrapping it around above your ears and around the back of your head.
If you have longer or shorter hair, there may be some tolerance either way.
So if you prefer a tight fit, go for a smaller size and if you prefer a loose fit, go for the bigger size. If you are uncertain, always go for the tighter size.
CMS use of different interior fit shapes arises from its feeling that one of the main consumer benefits of a good fit is improved comfort.
Of all its advancements, innovations and features that have received critical praise, the one singled out most often is CMS helmets comfort.
On its own, comfort seems a simple thing. In truth, few things are more involved, more complex or inter-related than the search for, and achievement of, comfort in an enclosed, close-fitting motorcycle helmet.
And fit, along with such elements as weight, shell materials and shape, balance, comfort foam type, density and placement, plays a major role. More specifically, CMS uses complex multiple-density comfort padding foams that, besides still being hand-fit into place, are specifically designed to fit into a particular part of the interior to deliver even better fit and comfort.
CMS is also incorporating AIR FITTING SYSTEM in some of its helmets improving the fitting technology which allows riders to custom fit upgrading even more the comfort and security. Once the helmet is in place custom micro adjustments can be made by inflating the AFS according to riders' personal preference.
Noise' experienced in a helmet is very personal.
One person may feel comfortable with a certain noise level, while another will experience it as very uncomfortable.
The source of noise in a helmet is mainly the environment (wind, traffic, motorcycle) but also the position of the rider on the bike and the configuration of the bike are importance.
A windscreen or fairing on the bike, but also the size and shape of it will have a great influence on the noise level within the helmet, because it will influence the turbulence around the helmet.
And it is the turbulence at back of the helmet that is the cause of the highest noise level within the helmet.
We extensively tested our helmets in windtunnels, but also on the circuits and in normal traffic conditions, with various motorcycles, speeds and the weather conditions.
These tests proved that CMS helmets are more among the quietest helmet tested.
PROFESSIONAL RACERS vs DAILY RIDERS
Every CMS helmet is made according the same standard.
In fact, CMS racers wear the exact same CMS helmet that can be found in a shop.
CMS has only one standard. All helmets are made the same, whether for a professional racing or a street or dirt rider.
