Helmets!! Motorcycle Helmets

I saw a dream on  helmets!! Yea Motorcycle helmets!!

Yes anybody passionate about biking will be too serious about use of Helmets.

Here Goes the story of Helmets. In May 1935, T. E. Lawrence (known as Lawrence of Arabia!! Worth to watch the same movie) had a crash on a Brough Superior SS100 on a narrow road near his cottage near Wareham. He suffered serious head injuries which left him in a coma; he died after six days in hospital. Hugh Cairns, a neurosurgeon, who after Lawrence's death began a long study of what he saw as the unnecessary loss of life by motorcycle dispatch riders through head injuries. Cairns' research led to the use of crash helmets by both military and civilian motorcyclists.

Well point was to bring the background of Helmets usage!!
But which helmet I should use?? Here goes the type of helmets available in the market ( Well I am optimistic new types will come for sure).

Full face
A full face helmet covers the entire head, with a rear that covers the base of the skull, and a protective section over the front of the chin. I use this one.

Off-road / motocross

The motocross and off-road helmet has clearly elongated chin and visor portions, a chin bar, and partially open face to give the rider extra protection while wearing goggles and to allow the unhindered flow of air during the physical exertion of this type of riding.

Modular or "flip-up"

A hybrid between full face and open face helmets for street use is the modular or "flip-up" helmet, also sometimes termed "convertible" or "flip-face". When fully assembled and closed, they resemble full face helmets by bearing a chin bar for absorbing face impacts.

Open face or 3/4 helmet

The open face, or "three-quarters", helmet covers the ears, cheeks, and back of the head, but lacks the lower chin bar of the full face helmet. Many offer snap-on visors that may be used by the rider to reduce sunlight glare. 

Half helmet

It has essentially the same front design as an open face helmet but without a lowered rear in the shape of a bowl. The half helmet provides the minimum coverage generally allowed by law in the USA, and British Standards 2001:1956.

Indian Standard for the Helmets is IS 4151 (Indian Standard, Bureau of Indian Standards, India)
PS: I saw a dream on the new helmets!! I will come back on the same in the next posting.
