Expiry Date

If you’re wondering when to replace your motorcycle helmets, check the expiry date. But do helmets expire? Yes, helmets have an expiry date that counts from the manufacturing date. Depending on the brand, a helmet’s lifespan can be between 3 to 5 years. Composite helmets, those with shells made of materials like fiberglass, carbon fiber, Kevlar, Dyneema, etc. tend to last longer than Thermoplastic shell helmets made from materials like ABS and Polycarbonate. Thermoplastic shells are more prone to degradation by long exposure to sunlight and some chemicals.

However, it is essential to note that the lifespan varies depending on the care.  For instance, exposure to different weather conditions affects the lifespan of a motorcycle. 

After A Crash/Accident

Any time you are involved in a crash or accident when the helmet suffers an impact it is time to replace the motorcycle helmet. You don’t have to see any visible signs of damage as the most serious damage is likely to be internal in the EPS (expanded polystyrene) liner.

So why do you need to replace your helmet if you have an accident? Usually, the impact can weaken or destroy the helmet’s shell or liner material, which decreases its ability to protect you in future accidents. Therefore, even if your helmet looks fine outside, it might not offer the same level of protection as a new one.

As you wear your helmet over time, it will naturally loosen up. The loosening is due to both the materials stretching and your hair and skin oils breaking down the helmet’s interior. Similarly, the helmet may be tight if you increase your diet or gain weight over time.

Whether the helmet is tight or loose, you’ll want to replace it. A properly fitting helmet should be snug and cozy. You should be able to fit no more than two fingers between the strap and chin. Otherwise, it’s too tight or loose for you. You don’t want to get a headache from a helmet being too tight but being too loose is even a worse problem as it is dangerous and increases the likelihood of the helmet coming off in the event of a fall.

When it Falls

One of the best times to replace motorcycle helmets is when they fall from a considerable height. For example, on a bookshelf, off the top of a truck, or on a ledge or roof. A fall can cause severe damage, even if the helmet doesn’t hit anything hard but the floor. And the fall doesn’t have to be from extreme heights; 2 meters is enough to seek a replacement.

However, there may be exceptions to the free fall factor.  For example, the fall will be less catastrophic if the helmet accidentally drops on a cushioned surface. But if the helmet fell on a hard surface, there is a possibility it generated enough force to cause damage.

Natural Wear and Tear

Over time, your helmet will succumb to wear and tear. The outer shell of a thermoplastic helmet will degrade due to the sun’s UV rays, causing them to weaken and break down. Humidity and heat can also cause the helmet to lose shape, become brittle, and ultimately crack.

On the other hand, the inner sponge and cushioning will also break down and lose their suppleness. This breakdown usually happens within the 3–5-year period. Together, these factors will affect the helmet’s ability to protect your head in the event of an accident.

Malfunction Components

For the helmet to protect you, all the components must be working correlatively. And if they aren’t, it’s when to replace the motorcycle helmet. Some essential elements that may malfunction include the helmet’s straps and fasteners. The straps become frayed or weak over time, while the pins may become loose or undone.

Malfunctioning can be catastrophic during an accident. For example, if the straps aren’t in place, the helmet can fly off or not stay in place during an accident, exposing your head to serious injury. If the face shield is cracked or scratched, it won’t be able to protect your eyes from debris in the event of an accident.
