Crash Injuries


Helmet Ergonomics Four basic components work together to provide protection in the motorcycle helmet; and outer shell, an impact-obsorbing liner, the comfort padding, and a good retention system. 1) Outer Shell Usually made from fiber-reinforced composites or thermoplastics like polycarbonate. It is designed to compress when it hits anything hard. That action disperses energy from the impact to lessen the force before it reaches the head. 2) Impact-absorbing Liner Made of expanded polystyrene (Styrofoam) which cushions and absorbs the shock as the helmet stops and the head wants to keep moving. Both the shell and the liner compress if hit hard, spreading the forces of impact throughout the helmet material. The more impact-energy absorbed, the less there of it to reach the head and do damage. Some helmets are designed to break at the jaw to prevent the neck from breaking. A helmet should be replaced if any damage occurs to the inner liner, even if the helmet has no cracks or damage on the shell. 3) Comfort Padding Soft foam and cloth layer which helps keep you comfortable and the helmet fitting snugly. 4) Retention System (chin strap) This is the one piece which keeps the helmet on in a crash. Keep it securely fastened.


Fitting Helmets Finding the Right Size: Instead of guessing a helmet size, a good starting point is to measure your hat size. To do this, measure your head at its largest circumference, which is usually just above the eyebrows and around the back. Use the chart below in order to determine your hat size, rounding up if your size falls between numbers.

Trying on the Helmet: - The helmet should fit snugly and may even feel a bit too tight until it is in place correctly. A helmet loosens up a bit as the comfor liner compresses through use. A new helmet should be as tight as you can comfortably wear it. - Move it from side to side and up and down. If it fits right, your skin should move as the helmet is moved. - The cheek pads should touch your cheeks without pressing uncomfortably - There should be no gaps between your temples and the brow pads - If the helmet has a neck roll, it shouldn’t push the helmet away from the back of your neck - On full-face helmets, press on the chin piece. The helmet or face shield should not touch your nose or chin. If it does, it will surely do so at speed from wind pressure. - With the chin strap securely fastened, try rolling the helmet forward off your head. You shouldn’t be able to pull it off. If you can, the helmet is too big.

Lightest option

Brims or similar sun protection popular additions.

Chin bar flips up over forehead, allowing for speech and eating convenience.

Plastic face shield swivels open.

Better air-flow for face.

“open-air feeling”

Riding in “up” position can cause more wind resistance.

“A ten dollar helmet for a ten dollar head.”

“The average customer will buy the cheapest helmet or a half helmet, then come back after a few thousand miles for a full face, safer helmet.”

“I wear the best.” “Retro will always be cool.” “It’s more fun to ride a slow bike fast than a fast bike slow.”


Common Modifications

Quick Strap •

Normal straps are “D Ring” closures

Clear visors let in a lot of light

Hard to use while wearing gloves

Tinted visors only dull bright glares

Helps with latching

Many people use normal tapes to mask the sun out

Costs about $10

Squeegee

Tape Visor

Comm System

Visors are prone to getting covered with rain drops

Can also get mud that obstructs view

Costs about $5

Helmets can make one feel disconnected from the experience and pasengers Communications systems allow for music and rider interaction

Goggles/Glasses •

Eye protection is required by law

Many riders need protection from the sun

Goggles also help eyes from getting too dry

Typical cost is $20 - $100

Can cost several hundred dollars
