How to clean your helmet for better performance!
In order for your helmet to provide the maximum level of performance and service, proper care and attention to it's condition and general upkeep is essential. Clean the exterior and interior of your helmet regularly. Use a soft cloth with mild detergent, using only lukewarm water. Never use gasoline (petrol), thinners, benzene or any other solvents or chemicals because they can adversely effect the shock absorbing inner liner and plastic components.
The comfort liner and cheek pads are fully removable, washable and replacements are available usually. Carefully hand wash and air dry the comfort liner and cheek pads when required. When the comfort liner is damp or wet due to perspiration or rain, always dry the helmet and liner in the shade, gentle air movement through the material will speed the drying process.

Reviews: Masei Helmet Quality - OK
Masei helmets are quite reasonable ranging from US$70 to US$180. Their quality is fair.. quite similar to AFX ones. They mostly import from Taiwanese and Chinese OEM makers. Their Quality Control are still not reaching very top level of famous brands.
Masei graphics are fancy, but the finish is not fairly done. Their gloss clear coat seems thinner. The decals are placed under the clear coat, giving the helmet a more finished look. Again, their gloss clear coats are softer than normal.
Masei helmets look all OK, but the quality of their modular locks and the overall execution are not reaching top-class levels yet. For example, the helmet seems to have a lot of lateral flexibility. When the rotating visor is closed and latched, I can squeeze the helmet and it flexes, both at the shell and around the sides of the chin bar on the rotating visor.
In my opinion. I guess if you're really limited on funds and you really want a good looking modular helmet with fancy graphics, Masei is definitely the best choice. On the market, a normal flip-up costs you at least US$139, but you can get them for US$99 sometimes online.

Why ARAI Helmets are so expensive? US$550 vs US$65
So far, Arai is the best-known helmet on the market, because they have been in business for decades. First comes first serves! I do not believe that at this moment they are the best helmet, since many middle-range helmet brands have improved their quality and also developed more features such as LED, blue-tooth, carbon fiber... However, Arai helmet quality control (QC) is definitely still the best.
Every Arai helmet is virtually 100% handmade. Each craftsman signs the helmet shell along the way. And every helmet is hand inspected at least three times during construction. Not every hundredth helmet, or every tenth one — every single helmet. I went to inspect some Taiwanese helmet makers in mass production (probably 5,000 helmets daily). There are no way they can do eyesight inspection on every helmet.
The price of DOT-approved helmets, let's say full face, can range from US$65 to US$550 - 10 times. Their price difference are coming mostly from their marketing, sponsorship, quality control, and R&B. Big brands spends most of their operating costs on these things.

Motorcycle Helmet Impact Absorption Test for DOT & ECE
The ECE standard has the most stringent 'peak g' rating which on face value is the most re-assuring. However, while the other standards (SNELL and DOT) all employ a hemispherical anvil which increases the concentration of loading and challenges the shell to withstand puncturing, the ECE does not and the nearest equivalent is the kerbstone.
During the test, the helmet is fitted to a metal head and dropped onto a steel anvil from a height of 287cm in order to get an impact speed of 27km/h. Four points on the helmet are each tested once and the anvils are both flat and rounded. Furthermore, the helmet is then dropped chinguard first onto a flat anvil from a height of 155cm. The velocity and duration of impact are both measured by sensors on the dummy head and when analysed, the acceleration of the head due to gravity must not exceed 275g.
The Head Injury Criteria (HIC) factor is a measurement of the total impact energy onto the head. It is usually calculated by multiplying the velocity with the duration of impact. The maximum permissible figure for this is 2,400. Reducing the total peak g and also the duration of impact will provide the rider with the best protection.
Chinstrap testing is also essential for helmets to get the necessary certificates.The chin strap is also tested by hanging a mass from it (a static load) and then dropping a proportion of this mass (a dynamic load) from a height of 75cm. This must not displace the chin strap by more than 35mm (from the dynamic load) and the static load must not displace the chin strap by more than 25mm.

California Planning Motorcycle Smog Checks
For those of you living and riding in the state of California, you should be aware of a proposed senate bill that will require smog checks for motorcycles. Senate Bill 435, introduced by California State Senator Pavley on February 26, proposes smog checks on motorcycles, beginning January 1st, 2012, for all motorcycles model year 2000 or newer. All motorcycles had previously been excluded.
SB 435, as introduced, Pavley. Smog check program: motorcycles. Existing law establishes a motor vehicle inspection and maintenance program (smog check), administered by the Department of Consumer Affairs, that provides for the inspection of motor vehicles upon registration, biennially upon renewal of registration, upon transfer of ownership, and in certain other circumstances. Existing law exempts from biennial inspection all motorcycles until the department implements test procedures applicable to motorcycles. Violations of smog check requirements are a crime. This bill would require the department to include model-year 2000 and newer motorcycles in the smog check program beginning January 1, 2012.
If you would like to comment on this bill, the time to contact your state legislators is now.
