When Should You Replace Your Motorcycle Helmet?

Part of our Motorcycle Helmet Buying Guide: How to Choose the Right Helmet

How long does a motorcycle helmet last? Is the five-year replacement rule genuine? And if you've dropped your helmet onto the ground, does that mean you need to buy another one?

These are questions almost every motorcyclist encounters eventually.

A motorcycle helmet doesn't have an unlimited service life. Its protective materials, comfort padding, retention system and other components can deteriorate through use, age, impact and improper storage.

But the advice isn't quite as simple as replacing every helmet automatically on its fifth birthday.

Manufacturers provide different guidance, and the circumstances matter. A helmet involved in an accident is a very different situation from one that has been stored carefully and used occasionally.

This guide explains when a helmet should be replaced, what damage to look for and how to care for it properly.

If you're considering a replacement, you can browse motorcycle helmets at Franklin Motors.

Quick decision guide

Situation Recommended action
Helmet worn during a crash involving a head impact Replace it
Shell cracked or impact liner damaged Stop using and replace
Helmet dropped onto hard ground Do not assume it is safe; follow manufacturer guidance
Helmet rolled from a sofa onto carpet Often less concerning, but inspect and follow manufacturer guidance
Chin strap or retention system damaged Stop using until the manufacturer confirms an approved remedy or replacement
Helmet has become excessively loose Reassess fit; replace if secure fit cannot be restored using approved components
Helmet approximately five years old Check manufacturer replacement guidance, use and condition
Visor scratched but helmet otherwise sound Replace the visor with a compatible approved part

How long does a motorcycle helmet last?

Around five years is a commonly recommended replacement interval for motorcycle helmets in normal use.

However, five years isn't a universal expiry date that applies identically to every helmet.

The correct replacement interval depends on the manufacturer's instructions, the helmet's age, how often it is worn, its condition and its history.

For example, HJC Europe recommends replacing helmets after approximately five years, depending on use. The Snell Memorial Foundation also recommends replacement after five years of normal use, but notes that unused helmets stored in good condition do not automatically expire after five years.

The UK government's SHARP programme provides conservative guidance around helmet lifespan and replacement, particularly for helmets used frequently.

What affects how long a helmet lasts?

Several factors influence its condition:

  • Frequency of use.
  • Exposure to sunlight, heat and moisture.
  • Sweat, hair products and cleaning chemicals.
  • Repeated putting on and removing.
  • Wear to the comfort padding.
  • Condition of the chin strap and fastening system.
  • Accidental impacts or damage.
  • Storage conditions.

A helmet used for daily commuting throughout the year may experience more wear than one used occasionally during summer.

However, a lightly used helmet isn't automatically safe simply because it looks clean.

Its age, materials and manufacturer guidance still matter.

Should you replace your helmet every five years?

Treat five years as a useful point at which to review your helmet's suitability and the manufacturer's advice, not as permission to ignore its condition until then.

Some manufacturers recommend earlier replacement. Others may provide different guidance depending on the helmet or how its service life is measured.

If your manufacturer specifies a replacement interval, follow it.

A helmet that's damaged or has suffered a significant impact may need replacing immediately, regardless of whether it's six months old or six years old.

Does a motorcycle helmet have an expiry date?

Motorcycle helmets aren't generally labelled with a universal expiry date in the same way as certain other products.

They may carry a date of manufacture, along with approval information and manufacturer identification.

The manufacture date can be useful when determining the helmet's age, but it is not automatically the same as its final safe-use date.

Manufacture date versus purchase date

A helmet may have been manufactured before you purchased it.

For example, a helmet bought in 2026 might have been manufactured in 2025.

Whether the recommended replacement interval is measured from manufacture, purchase or first use depends on the manufacturer's particular guidance.

Don't assume every brand uses the same starting point.

Where can you find the manufacture date?

The location varies by manufacturer and model.

You may find identifying information on a label inside the helmet or in its accompanying documentation.

Consult the specific manufacturer's instructions if you're unsure where to look.

Don't confuse the helmet's ECE approval number with its date of manufacture.

ECE 22.06 identifies an approval series, not the year the helmet was made.

Should you replace your helmet after a motorcycle accident?

Yes, if your helmet has experienced an impact that may have required it to absorb crash forces, you should replace it.

A motorcycle helmet is designed to manage impact energy through its structure, including an impact-absorbing liner.

During a substantial impact, parts of that structure may deform or become damaged as they absorb energy.

This damage isn't necessarily visible from the outside.

A helmet may look almost untouched while its protective performance has been compromised.

What if there are no visible scratches?

The absence of obvious damage doesn't prove the helmet is safe.

The impact-absorbing liner may have compressed, or other components may have experienced forces that cannot be assessed through a casual visual inspection.

This is why manufacturers advise against continuing to use a helmet that has absorbed a crash impact.

Can you repair a crash-damaged helmet?

Do not attempt to repair a damaged protective shell or impact-absorbing liner yourself.

Replacing the visor or comfort padding cannot restore a helmet whose protective structure has been compromised.

Some manufacturers offer inspection or specific repair services, but not all damage can be assessed or repaired.

If your helmet has absorbed a crash impact, replacing it is the appropriate course of action unless the manufacturer provides a clear, authorised determination otherwise.

Don't rely on a shop assistant, friend or online photograph to establish that a crash-damaged helmet remains safe.

I dropped my motorcycle helmet. Do I need to replace it?

This is one of the most misunderstood questions about helmet care.

The answer depends on how the helmet was dropped, what it struck and the manufacturer's instructions.

A helmet falling from a motorcycle seat onto concrete is not necessarily comparable with one rolling from a low sofa onto a carpet.

However, you cannot reliably determine every form of damage simply by looking at the outside.

Dropping an empty helmet from a low height

When an empty helmet falls a short distance, the impact-absorbing liner may experience different forces from those produced when a rider's head is inside it.

SHOEI's guidance acknowledges this distinction.

For a low-height drop without a head inside, SHOEI explains that damage may sometimes be limited to paintwork or external attachments.

However, the company also emphasises that the circumstances cannot always be evaluated reliably and that visible shell damage requires replacement.

Other manufacturers adopt more conservative recommendations.

Dropping a helmet onto concrete

A helmet falling from the seat of a motorcycle onto concrete or another hard surface deserves particular caution.

SHARP warns that even an apparently minor drop can have unseen consequences.

If your helmet strikes a hard surface, don't assume it is safe simply because the paint looks undamaged.

Stop using it until you've consulted the manufacturer's guidance and resolved any uncertainty.

What if something was inside the helmet?

A helmet dropped while containing an object may experience different loading from an empty helmet.

An object inside the helmet can place pressure on the liner during impact.

That is another reason why the circumstances of the drop matter.

What should you do after dropping your helmet?

  1. Stop and consider exactly what happened.
  2. Check the shell, visor, fastening and accessible components for signs of damage.
  3. Consult the manufacturer's instructions for your particular model.
  4. Contact the manufacturer or authorised distributor if the guidance is unclear.
  5. Replace the helmet if damage is present, replacement is required by the manufacturer, or its protective integrity cannot be established.

Don't perform your own impact test by dropping the helmet again or striking it to see whether it is damaged.

A visual inspection is useful for identifying obvious problems, but it cannot guarantee that the protective structure is intact.

What happens inside a motorcycle helmet during an impact?

Understanding how a helmet works helps explain why hidden damage matters.

Most road motorcycle helmets incorporate several important components.

Outer shell

The outer shell helps distribute impact loads and contributes to the helmet's overall protective structure.

It may be made using polycarbonate, fibreglass, composite materials or carbon fibre.

The shell material alone does not determine a helmet's safety performance.

Impact-absorbing liner

Beneath the shell is an impact-absorbing liner, commonly made from expanded polystyrene, known as EPS.

This liner is designed to deform under specified impact conditions, helping manage energy that would otherwise be transmitted towards the head.

When EPS is compressed during a substantial impact, it does not simply spring back to its original protective condition.

Damage may be difficult to see without dismantling the helmet, which riders should not attempt.

Comfort padding

The softer interior padding helps the helmet fit securely and comfortably.

Unlike the impact-absorbing liner, some comfort components are designed to be removable or replaceable.

However, replacing comfort padding does not repair a damaged EPS liner.

Retention system

The chin strap and fastening mechanism help keep the helmet correctly positioned.

A helmet with a damaged or unreliable retention system should not be used.

The complete helmet works as a protective system. Damage to one essential component can make it unsuitable for further use.

Seven signs your motorcycle helmet may need replacing

Not every problem involves an obvious accident.

Regular use can gradually affect a helmet's condition and fit.

1. Visible damage to the shell

Cracks, splits, deformation or other significant structural damage are reasons to stop using the helmet.

Do not attempt to hide damage with paint, adhesive or filler.

2. Damage to the impact-absorbing liner

If the protective liner shows signs of cracking, crushing or deformation, the helmet should no longer be used.

Don't remove or alter the protective liner to investigate.

3. Damaged chin strap or fastening mechanism

Fraying, damaged stitching, defective buckles or an unreliable locking mechanism can affect retention.

Do not continue riding with a helmet that cannot be fastened securely.

4. The helmet has become too loose

Comfort padding can compress over time.

If the helmet begins to move excessively or no longer fits securely, its suitability needs to be reassessed.

Some helmets allow replacement of approved comfort padding, but this cannot correct every fit problem.

5. Damaged or deteriorating internal components

Look for significant deterioration, loose components or materials that are breaking down.

If protective components appear affected, stop using the helmet and seek manufacturer guidance.

6. Damage caused by chemicals or excessive heat

Petrol, solvents, inappropriate cleaning products and excessive heat can damage helmet components.

Some damage may not be immediately visible.

If the helmet has been exposed to a substance or condition the manufacturer warns against, seek advice before using it again.

7. The helmet has reached its recommended replacement interval

Even without visible damage, the manufacturer may recommend replacement after a particular period.

Follow that guidance rather than assuming an apparently clean helmet will remain suitable indefinitely.

Can you replace a helmet's cheek pads or interior lining?

Sometimes.

Many helmets have removable comfort liners and cheek pads that can be cleaned or replaced.

This can help maintain hygiene and, where approved by the manufacturer, restore aspects of the intended fit.

However, there are important limits.

Comfort padding is not the protective liner

The removable fabric-covered padding isn't the same as the EPS impact-absorbing liner.

The EPS liner is a critical part of the helmet's protective structure.

It must not be cut, compressed, modified or replaced using improvised materials.

Can new cheek pads make an old helmet safe again?

Not necessarily.

If the only problem is worn, manufacturer-replaceable comfort padding, an approved replacement component may help restore fit.

But it does not reverse damage, ageing or deterioration elsewhere in the helmet.

If the helmet has reached the manufacturer's replacement interval or its protective structure is compromised, replacing comfort pads won't resolve that.

Use approved replacement components

Always use components specified as compatible with the exact helmet model.

Do not fit generic padding simply because it appears to be the right size.

When should you replace a motorcycle helmet visor?

A damaged visor doesn't always mean the complete helmet needs replacing.

Visors are often replaceable components, provided the helmet and visor mechanism remain sound.

However, a scratched or damaged visor can reduce visibility, particularly in rain, low sunshine or darkness.

For Irish riders, this is particularly important during winter commuting.

Signs that a visor needs replacement

Consider replacing the visor if:

  • Scratches significantly affect your view.
  • The surface has become cloudy or distorted.
  • Cracks or other damage are visible.
  • The visor no longer closes correctly.
  • The locking or attachment arrangement is damaged.
  • Its optical condition makes riding visibility unsafe.

Use a manufacturer-approved visor compatible with your particular helmet.

If the helmet's visor mounting structure itself is damaged, a new visor may not be enough to correct the problem.

What about Pinlock inserts?

An anti-fog insert is a separate component.

If the insert is damaged, distorted or no longer working correctly, follow the manufacturer's advice on cleaning, adjustment or replacement.

Use the correct insert for your visor rather than attempting to fit an incompatible alternative.

Does an ECE 22.05 helmet need replacing because ECE 22.06 exists?

Not solely because a newer approval standard has been introduced.

ECE 22.06 established updated helmet approval requirements, including additional impact testing.

However, the introduction of a newer standard doesn't automatically mean every older ECE 22.05 helmet already in use has become unsafe.

A rider should consider the helmet's condition, age, fit and manufacturer guidance, alongside the applicable legal requirements.

For a new purchase, ECE 22.06 is the standard we recommend looking for.

If your existing helmet is ageing or due for replacement, upgrading to an appropriately approved modern helmet is a sensible opportunity to consider current models.

Our Motorcycle Helmet Safety Standards Guide explains the differences between ECE 22.05 and ECE 22.06.

How to make your motorcycle helmet last longer

Good care cannot make a helmet last indefinitely, but it can help protect its condition during normal use.

Store it somewhere secure

Avoid leaving your helmet where it can fall onto a hard surface.

Use a suitable helmet bag or storage space.

Don't leave it balanced on the seat or handlebars of your motorcycle.

Avoid excessive heat

Don't store your helmet close to heaters or other significant sources of heat.

Follow the manufacturer's storage recommendations.

Keep it away from petrol and solvents

Fuel, solvents and some aggressive cleaning products can damage helmet materials.

This matters when stopping for fuel or cleaning motorcycle equipment.

Never use petrol to remove stubborn marks from your helmet.

Clean it correctly

Follow the manufacturer's instructions for cleaning the shell, visor and removable interior.

Gentle cleaning products approved for the relevant materials are preferable to harsh household chemicals.

Keep the visor in good condition

Clean the visor carefully to avoid scratching it.

Replace a damaged visor rather than continuing to ride with impaired visibility.

Inspect it regularly

Check the helmet before use, particularly after it has been dropped, knocked or stored for a long period.

Pay attention to the shell, strap, fastening system, visor and accessible interior components.

Use the helmet correctly

Fasten it properly every time you ride.

Don't modify the protective shell or liner, and only attach accessories in accordance with the manufacturer's instructions.

What about motorcycle helmets that have been stored for years?

A helmet can deteriorate even when it isn't being worn.

Its condition depends on the materials, storage environment, age and manufacturer's recommendations.

An unused helmet stored correctly may be in better condition than one that has been worn daily, but the absence of use is not proof that it remains suitable indefinitely.

Is an unused five-year-old helmet automatically unsafe?

Not necessarily.

The Snell Memorial Foundation explicitly distinguishes unused helmets stored in good condition from helmets that have experienced five years of normal use.

However, this doesn't override the instructions of the actual helmet manufacturer.

Before using a helmet that has been stored for an extended period, check its age, condition, fit and the manufacturer's guidance.

What if you don't know the helmet's history?

If you cannot establish whether a helmet has been dropped, involved in an accident or stored incorrectly, it's difficult to assess its suitability.

For this reason, buying a second-hand motorcycle helmet with an unknown history is not recommended.

A new helmet from a reputable retailer offers much greater certainty about its condition and ownership history.

Should you sell or donate your old motorcycle helmet?

A helmet being retired because of damage, age or uncertain protective integrity should not be passed on for somebody else to ride in.

The next owner may not know why it was replaced.

SHARP and HJC both advise against passing retired helmets on for continued use.

If you are disposing of an old helmet, make sure it cannot easily be recovered and reused as protective equipment.

Follow local waste-disposal guidance and avoid leaving an apparently usable but unsafe helmet where somebody might take it.

There may be uses for a clearly decommissioned helmet as a non-riding display item, but it should never be represented as suitable protective equipment.

Motorcycle helmet inspection checklist

A short inspection before riding can help identify developing problems.

Outer shell

  • Look for cracks, deformation or significant damage.
  • Check for damage around vents, attachments and other components.

Chin strap and fastening

  • Check for fraying, damaged stitching or faulty mechanisms.
  • Ensure the retention system fastens correctly.

Interior

  • Check the accessible padding and lining for unusual wear or damage.
  • Make sure approved removable components are correctly fitted.

Visor

  • Check for cracks, significant scratches or distortion.
  • Make sure the visor operates and closes correctly.

Fit

  • Check that the helmet remains snug and securely positioned.
  • Reassess the fit if the padding has become noticeably compressed.

History and age

  • Consider whether the helmet has suffered an impact.
  • Check its age and the manufacturer's replacement recommendations.

A visual inspection cannot guarantee that a helmet is structurally sound, but it can help identify obvious reasons to stop using it.

Frequently asked questions

How often should you replace a motorcycle helmet?

Around five years is a common recommendation for normal use, but the correct interval depends on the manufacturer, usage and condition. Replace a helmet sooner if it has suffered a damaging impact or becomes unsuitable for use.

Do motorcycle helmets expire after five years?

Not automatically. Five years is a commonly recommended service interval, not a universal expiry date. An unused helmet stored properly does not necessarily become unsafe on its fifth birthday. Follow the manufacturer's specific guidance.

Should I replace my helmet after dropping it?

It depends on the circumstances and manufacturer guidance. A low-height drop without a head inside may be less concerning than a crash impact, but damage can be hidden. Do not assume a helmet is safe after a hard impact simply because no damage is visible.

Can a motorcycle helmet survive a crash?

A helmet may protect the rider during a crash by absorbing impact energy, but its protective structure can be compromised in the process. A helmet that has absorbed a crash impact should be replaced.

Can you repair a cracked motorcycle helmet?

Do not attempt to repair a cracked protective shell or damaged impact-absorbing liner yourself. A helmet with compromised protective structure should be replaced.

Does a scratched visor mean I need a new helmet?

Not necessarily. If the helmet itself is sound and its visor mechanism remains suitable, a compatible approved replacement visor may resolve the problem. Significant visor damage should not be ignored.

Can I replace the inside padding instead of buying a new helmet?

Some manufacturers provide approved replacement comfort padding. This may resolve certain wear or fit issues, but it does not repair protective liner damage or extend the helmet's service life beyond the manufacturer's guidance.

Is a helmet still safe if it has never been dropped?

A clean impact history is important, but it doesn't guarantee indefinite suitability. Age, chemical exposure, heat, component wear and poor fit can also make a helmet unsuitable.

Do carbon fibre helmets last longer than polycarbonate helmets?

Not necessarily. Service life depends on the complete helmet construction, manufacturer recommendations, use and storage. Shell material alone does not establish a safe replacement interval.

Should I replace my ECE 22.05 helmet with an ECE 22.06 model?

A newer approval standard alone isn't necessarily a reason to discard an otherwise suitable existing helmet. However, if your helmet is damaged, ageing or due for replacement, choosing a current ECE 22.06-approved model is sensible.

Can I buy a second-hand motorcycle helmet?

We recommend buying new. A second-hand helmet may have experienced impacts, improper storage or hidden damage that cannot be verified.

What should I do with an old motorcycle helmet?

Don't sell, donate or pass on a helmet that is no longer suitable for riding. Dispose of it responsibly in a way that prevents somebody else from unknowingly using it as protective equipment.

Ready to replace your motorcycle helmet?

If your helmet has suffered a significant impact, shows structural damage, no longer fits securely or has reached the manufacturer's recommended replacement interval, it's time to consider a new one.

Don't wait for obvious damage if the helmet may have absorbed crash forces.

At Franklin Motors, you can explore motorcycle helmets for commuting, touring, sports riding and adventure use, including full-face, modular, adventure and open-face designs.
