Do Motorcycle Helmets Break-In?

Yes, they break. a helmet is a piece of equipment that’s meant to protect you from a head injury in the case of an accident. it doesn’t do this by being soft and pliable, though – it does it by being hard and inflexible.

if a helmet is too hard then it will do a good job of protecting you, but your head will have to endure all the force. if it’s slightly pliable though, then it won’t be doing such a good job protecting you, but your head won’t have to endure anywhere near as much force.

the analogy I like to use is of a brick wall. if you smash your head against the brick wall, it does an excellent job of protecting you; but it’s not much fun smashing your head against brick walls all day because it hurts like hell and you don’t want to do that.

why do motorcycle helmets break-in?

it’s because of the way it was manufactured, and its also because of other factors like:

  1. The type of material used- a helmet can be made from fiberglass, carbon fiber, or a combination of both. usually, fiberglass helmets are more popular because they have a wider price range and it is still strong enough to protect your head from minor accidents. the downside is that it has a slower impact absorption rate compared to carbon fiber which is also more expensive.
  2. It also if someone hit the helmet with something like a bat or if it hit the ground.
  3. If you fall hard on the ground with your helmet chances will that it will break even if the label says it’s good for multiple impacts.
  4. If you leave it under the heat of the sun and with high humidity for a long time, the glue and plastic materials used in making the helmet (especially cheaper ones) will start to degrade.

so there you have it it was possible reasons why helmets break-in.

How much force does it take to break a motorcycle helmet?

it takes approximately from 180lbf-250lbf to break a helmet depending on the type of helmet, there are three main types of helmets and the article will describe the three and which one is most effective if they were to be in an accident.

  1. Full face: this style has a chin bar that protects the jaw and covers the entire head from front to back. The force required to break or damage this kind of helmet is above average with a range between 215-220lbf
  2. Open face: it only covers half of your face leaving your mouth, nose, cheeks, and eyes exposed
  3. Half shell: half of your face is protected, this helmet does not cover the back of your head, it also leaves some spots on the side of your chin exposed.

What is inside a bike helmet?

When you buy a bike helmet there is usually foam padding that covers the inside of the helmet, this foam pads the impact and reduces the force of impact. The types of helmets also differ:

it also made from High-Density EPS (Expanded Polystyrene): Is made up of small beads, it is very lightweight but can be easily damaged upon impact.

High-Impact EPS (Expanded Polystyrene): this is the most common and strongest type of EPS, it absorbs more impact than High-Density EPS and is made up of bigger beads.

Carbon Fiber: its main purpose is to make the helmet as light as possible and is very effective for that specific reason since most full-face helmets weigh around 700 pounds or less, this material provides strength but does not absorb impact like High-Density or High-Impact EPS would do.


helmets are made to absorb the impact of an accident, it is better to have a helmet that is too hard rather than one that has to give because it will save you from much more damage.
