Real change in helmet technology finally came in 1935, with the over-the-handlebars death of writer, army officer and historical badass T. Lawrence (known as “Lawrence of Arabia” to his groupies).
Lawrence was treated by a neurosurgeon named Sir Hugh Cairns, who was compelled to study the effects of head trauma during a motorcycle crash.
I like new helmets and different styles, especially depending on my riding conditions.
If I’m using a windshield on a long trip, or just riding locally, I interchange helmets—even my old ones that didn’t get much use. I had heard that motorcycle helmet manufacturers recommend replacing helmets every five years, many every three years, but I assumed that was to help them sell more helmets.
FMVSS 218 sets standards in three areas of helmet performance: impact attenuation, basically energy absorption; penetration resistance; and finally the retention system effectiveness, and there are new product labeling requirements.Because his dad gave it to him, it could easily have been 20 years old.The thought never entered my mind, “is this helmet still good? As an adult, I bought many helmets, but safety was never my primary concern.Military headgear provide an excellent illustration. The risk of head injury, particularly in warfare, has been acknowledged throughout history.The use of protective headgear may be as old as warfare itself.It was not until a Californian named Herman Roth patented a protective helmet with an internal, energy-absorbing liner, that the modern helmet was born.
