How are motorcycle crash helmets made?

With the crash helmet being the only compulsory item needed by bikers to ride legally on UK roads, we give you an insight into the complexity of creating this lifesaving equipment.

The four basic elements of a motorcycle helmet are:

  • Outer Shell
  • Impact-absorbing liner
  • Comfort padding
  • Retention system

These four elements work together to provide protection in the most effective way in the result of an accident.

The thin, hard, outershell is made from either polycarbonate plastic, fiberglass or Kevlar. These plastics offer a protection barrier around the softer, foam lining of the helmet; the two main purpose of the hard shell is:

  • to prevent penetration of the helmet by a pointed object that might other puncture the skull
  • to provide structure to the inner liner so it doesn’t disintegrate upon abrasive contact with pavement

Fibreglass shells are highly recommended along with carbon fibre and Kevlar as they have the ability to make helmets lighter. The outershell is designed to be tough but also compress when it hits something hard therefore dispersing the energy to lessen the force before it reaches your head.

The inside features the soft, thick lining of the expanded “EPS” foam.  The foam liner needs to crush during any impact to increase the distance and period of time which the head stops and reducing its deceleration. The inner lining must not be more than 1 – 2 inches (2.5 – 5.1cm) thick otherwise this can make the helmet too stiff inside and not give enough movement if there were to be an accident.

Next is the comfort padding which is the soft foam/cloth layer that sits directly around your head and face making it more comfortable for elongated periods of time.

Finally, the retention system, commonly known as the chin strap, is the vital piece of the helmet that keeps it secured to your head during a crash. Make sure that your chin strap it fastened securely each and every time you put your helmet on.

Open face vs Full face

The age-old debate on what’s the best type of helmet to wear: open face vs full face. Many will say the style of bike you ride will determine the type of helmet you’ll purchase. It’s common for motorcyclists to own 2 or more helmets due to frequency of use and preferred style. 75% of motorcyclist owned and favour full face helmets, however 38% also own and wear flip up helmets too!

Full face

Full face is quite literally a full faced helmet, not one part of your face is exposed. These helmets have moveable visors so they can be flipped up if necessary. However, full faced helmets are deemed to be the safest because they offer the most protection.

Full face helmets are normally desired by those who partake in sports such as road racing and track riding as they are at a high level of vulnerability if an accident were to occur.

Open face

The whole of the face is exposed in this style of helmet. Often one to be worn when the weather is warmer, just watch out for bugs! Riders who opt for this style helmet often team it with a neck warmer/ neck tube to add a layer of protection to the face.

Helmet accessories

There has been an increase of helmet accessories over recent years to the ease of making them quick, easy and cheaply.

Visors

Similar to helmets, visors and goggles are also required to meet certain standards:

  • meet a British Standard and display a BSI Kitemark
  • meet a European standard offering at least the same safety and protection as the British Standard and carry a mark equivalent to the BSI Kitemark (UNECE Regulation 22.05)

Sunglasses 

Those riders who opt for an open-face helmet often wear a pair of sunglasses during the sunnier months. Sunglasses also need to meet certain standards to insure they provide the best protection.

Ventilation

When you’re standing inside a shop you’re not going to get a real feel for the helmet, so it could be an idea to ask if you could take it outside. You’ll need to remember that ventilation is going to be key during the warmer months to help keep you cool when you’re riding.

Modern helmets are normally fitted with an air control system which breaks off if you were to be involved in an accident so there’s no risk of any added injury to you. Helmets normally have a choice of 10 or 20mm vent holes dependent on how much airflow you desire, although they should all feature switchable covers.

So, what colour helmet should you pick?

There’s been a long debate about the colour of a motorcycle helmet and the correlation of accidents, although it is recommended to always wear hi-vis and bright colours to be seen on your motorcycle, you can’t go wrong with a stylish black!

Well we’ve decided to delve into this debate and see if we can answer it once and for all…

Does the colour of your helmet affect your visibility?

A recent poll conducted on Keep Britain Biking found that 64% of voters believed that the colour of your motorcycle helmet does impact your visibility on the roads.

Although 38% of bikers opt for a black helmet followed by white at 23% and then multiple colour designs at 13%. As always fashion trends and style changes but it’s safe to say there’s no right or wrong when it comes to purchasing a motorcycle helmet, all you need to remember is to look out for the SHARP rating.

Best places to purchase a motorcycle helmet

Looking after your motorcycle helmet

To make sure you can get the most out of your helmet, regardless if you wear it every day or once in a while, we’ve got some handy tips on how to maintain it:

  • Use wet wipes or wet towels to remove any bug splat you may have from your latest ride out, or if you’re already on a trip then keep some sorted under your seat
  • Invest in ‘helmet spray freshener’ which will help to mask any lingering smells
  • Use a damp soft cloth/microfiber towel with a mild detergent that you can wipe the shell with gently, this should remove any dirt and leave a shiny finish
  • If the inner lining of your helmet is removable then you have the extra advantage of taking out the lining and popping it on a delicate cycle to freshen it up.
  • Store your gloves in your helmet when you’re out and about? Think twice about doing as any residue of petrol on your glove could compromise the interior of your helmet
  • It’s essential to keep your helmet in a cool place and stored away correctly, if left in excessive heart, cleaning fluids or fuel it could damage the materials that are used to construct the helmet which keep you safe
  • Invest in a soft bristle toothbrush to get in those hard to reach places when cleaning the outside of your lid
