A motorcycle helmet is a type of helmet used by motorcycle riders. The primary goal of a motorcycle helmet is motorcycle safety- to protect the rider`s head during impact, thus preventing or reducing head injury and saving the rider`s life. Some Helmets provide additional conveniences, such as ventilation face shields, year protection, intercom etc.

The origins of the crash helmet date back to the Brook lands race track in early 1914 where the medical officer, a Dr. Eric Garner noticed he was seeing a motor cyclist with head injuries about every 2 weeks.

He got a Mr. Moss of Bethnal Green to make canvas and shellac helmets stiff enough to stand a heavy blow and smooth enough to glance off any projections it encountered. He presented the design to the Auto-Cycle Union where it was initially condemned, but they later converted to the idea and mode them compulsory for the 1914 Isle of Man TT races, although there was resistance from riders.

The best helmets today use composite materials which include fiberglass mixed will all manner of high-tech new-age materials ranging from aramids to carbon fiber. In every case, the new-age material is highly regarded for it is strength and resistance to decay under abrasion and to penetration

The motocross and off-road helmet has clearly elongate 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.

The visor is to allow the rider to dip his or her head and provide further protection from flying debris during off-road riding.

It will also keep the sun out of the eyes of the rider during jumps

The half helmet, also referred to as a “Shorty” in the USA and “Pudding Basin” or TT helmet in the UK and popular with Rockers and road racers of the 1960s in the British Isles.

It has essentially the same front design as an open face helmet but without a lowered rear in the shape of a bowl

The open face helmet cover`s 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. An open face helmet provides the same rear protection as a full face helmet, but little protection to the face, even from non-crash events

Although black helmets are popular among motorcyclists, one study determined they offer the least visibility to motorists. Riders wearing a plain white helmet rather than a black one were associated with a 24 % lower risk of suffering a motorcycle accident injury or death. This study also notes “Riders wearing high visibility clothing and white helmets are likely to be more safety conscious than other riders”.
