Did you know your motocross helmet has an expiration date? Find out why helmets expire, how to check your helmet’s age, and when to replace it to stay protected on every ride.
A motocross helmet might look tough enough to last forever, but the truth is every helmet has an expiration date. Even if the exterior seems fine, the internal protective materials, like EPS foam, can break down over time, reducing their ability to absorb impact when it counts.
Understanding how long your helmet remains safe is one of the smartest things any rider can do. Riding with an expired helmet can mean the difference between walking away or facing serious injury after a crash.

Do Motocross Helmets Expire?
Yes, motocross helmets do expire and every rider should know this important fact. No matter how well you take care of your helmet or how clean it looks on the outside, the protective materials inside have a limited lifespan.
Most trusted helmet manufacturers and safety organizations recommend replacing your helmet every five years from the date you bought it or from its original manufacture date. This rule applies even if your helmet has never been dropped, crashed, or damaged in a visible way.
This guideline covers all types of motorcycle and dirt bike helmets, whether you ride every weekend or only a few times a year. Following the five-year rule is the simplest way to make sure your helmet always gives you the best possible protection when you need it most.
Why Do Helmets Expire?
A motocross helmet does not last forever, no matter how sturdy it seems. Over time, several factors can weaken the materials that keep your head safe during a crash. Here is why every helmet eventually needs to be replaced.
Material Degradation
The foam liner inside your helmet, typically made from expanded polystyrene (EPS), and the outer shell can slowly degrade over time. Sunlight, sweat, heat, and even the natural oils from your skin all contribute to this breakdown. While your helmet might still look solid on the outside, the internal layers may no longer absorb impact energy as effectively as they once did.
Don’t wait until it’s too late. Shop new motocross helmets now and make sure your gear is as tough as you ride.
Wear and Tear
Regular riding compresses the comfort liner and the fit pads inside your helmet. As they wear out, the helmet may feel looser on your head, which means it might shift or come off during a crash. A snug fit is essential for proper protection, and old padding cannot hold its shape forever.
Advances in Safety
Helmet technology keeps getting better every few years. Features like improved impact management, lighter shells, and updated safety certifications mean that a helmet made today is often safer than one designed five or more years ago. Replacing your helmet on schedule helps you benefit from the latest protective advances.
When Should You Replace Your Helmet Sooner?
Following the general five-year rule is a good habit, but sometimes you need to replace your motocross helmet even sooner to stay safe. Here are the key situations when it is smart to get a new helmet right away.
After a Crash or Impact
If your helmet has been involved in any serious crash or has been dropped hard, it should be replaced immediately. Even if you cannot see cracks or dents, the internal foam liner may have absorbed impact energy and could fail to protect you properly in the next crash. One impact is often all it takes to weaken your helmet’s protective core.
Visible Signs of Damage
Always inspect your helmet closely. If you notice cracks in the shell, dents, loose or torn padding, or a liner that feels brittle or thin, it is time for a new helmet. These signs mean your helmet may not stay secure or absorb impacts like it should.
Age
Age alone can be a reason to replace your helmet early. Even if you don’t ride often, the internal materials naturally break down over time. Most safety experts recommend replacing your helmet every five years from the date of purchase, or seven years from the production date, whichever comes first.
Stay ahead of the wear. Browse new motocross helmets and ride with confidence knowing your protection is up to the challenge.
How to Check Your Helmet’s Age
Knowing exactly how old your motocross helmet is can help you decide when it is time for a replacement. Here is how to find that important information and follow the best guidelines for maximum safety.
Find the Date Stamp
Most reputable helmet brands include a production date sticker or stamp inside the helmet. To find it, gently lift or remove the comfort liner and look for a small label or imprint that shows the month and year the helmet was made. If you cannot find a date stamp or if you do not remember when you bought the helmet, play it safe and replace it as soon as possible.
Manufacturer Recommendations
Top brands like Shoei and Arai recommend replacing your helmet five years after purchase or seven years from the manufacture date, whichever comes first. Following these guidelines ensures your gear still performs as it should.
Not sure how old your helmet is? Take a minute to check the production date, usually found on a sticker inside the helmet. If it’s time for an upgrade, check out 6D Helmets and Bell Helmets, or shop all dirt bike helmets for more options.

Why Not Use a Used or Old Helmet?
Using a used or very old motocross helmet can put you at serious risk, even if it looks fine at first glance. Here is why sticking with a new, properly maintained helmet is always the safer choice.
Unknown History
When you buy or borrow a used helmet, you have no way to know how it was handled in the past. It might have been dropped or involved in a minor crash without showing visible damage. Even small impacts can weaken the foam liner inside, reducing its ability to protect you during a future crash.
Degraded Protection
Helmets naturally lose their protective strength over time. Older helmets, especially those more than seven years old, often have liners that have become brittle or have broken down completely. A helmet with a degraded liner cannot absorb impact energy the way it should, leaving your head more exposed during a fall.
For your own safety and peace of mind, always choose a helmet with a known history and replace it according to age and condition guidelines. It is a small step that can prevent big injuries.
Helmet Replacement Guidelines
Not sure when it’s time to replace your motocross helmet? Here are the key rules to follow for safe riding.
If it’s been five years since purchase, it’s time for a replacement—even if the helmet still looks fine. If it’s been seven years since its manufacture date, the materials may have degraded and should no longer be trusted for impact protection.
Always replace your helmet immediately after any crash or significant impact. Even one hit can compromise the integrity of the EPS liner and reduce its ability to absorb force.
Visible signs of wear—like cracks, dents, or loose padding—are a red flag. If your helmet doesn’t have a visible production date or you’re unsure how old it is, the safest call is to get a new helmet rather than take chances.
