Chin Strip

In order to prevent your head from moving, check that your helmet’s chin strap is in good condition. It might wear down and loosen with usage so ensure that it is snug before driving

It is easily replaceable so there’s no need to unnecessarily buy a new helmet. 

Inner paddings 

The inner paddings of your motorcycle helmet shield your head from the hard interior.

Luckily you don’t have to buy a new helmet, if your only concern is the inner paddings, they’re easily available and replaceable.

Avoid attempting to operate a motorbike while wearing a helmet with loose or no pads. The discomfort of the ride will increase as a result. Also, it will intensify the effects of your accident.

However, if your helmet is seldom used and the inside liner is somewhat worn out, it means it’s time to replace it. Similarly, if the comfort liner is worn out with little use, the EPS liner is also likely to be worn out.

EPS Liner

Expanded polystyrene, usually known as Styrofoam, is the most typical material used for the inner liner. It is also known as EPS.

The layer between the outer shell and the inner padding is the EPS liner. It cannot be changed and is not detachable from the helmet. 

EPS liners will outlast pretty much any other component on the helmet and retain its protective features for a really long time because they cannot degrade and break down from oil, sweat, and common chemicals we use on our face and hair.

Although it’s difficult to tell if your EPS liner is damaged or not, specialists can determine this by scanning the helmet.

One sign that may indicate the wearing out of EPS is when the inside paddings of the helmet start to deteriorate even with little use.

Outer Shell

Check the colors on the outer shell of your helmet to check if they have faded; this would indicate that the materials it is composed of, have degraded.

The most common materials used to make helmets include fiberglass, carbon fiber, Kevlar, ABS, and polycarbonate. 

These materials will naturally deteriorate if exposed to UV rays for an extended length of time, according to studies.

Moreover, keep an eye out for fractures, cracks, and other structural concerns..


The glue holding the pads to the rest of the helmet begins to deteriorate due to too much sweat and moisture and could cause you a risk, as it’s one of the reasons why helmets expire.
