How to Check a Used Helmet Before Buying

A used helmet can save you 50–70% off retail — and a used helmet can also be a dangerous buy. The good news: with a 5-minute inspection you can tell the difference. Here's exactly how to check a second-hand helmet before you hand over any money.

The 5 rules of used helmets

1. No crash history. If the seller can't confirm the helmet has never been dropped, walk away.
2. Less than 5 years old. Helmet EPS foam degrades from age, UV, and sweat — even if it looks new.
3. No visible damage. Shell cracks, dents, or deep scratches mean the structure is compromised.
4. It must fit. An old, expensive helmet that doesn't fit is worse than a cheap new one that does.
5. Original liner and pads. Replaced padding means it may have been crashed or rebuilt.

Check the manufacturing date

Every helmet has a production date printed somewhere inside — usually on a label under the liner or on the chin strap.

• Manufactured within the last 3 years — good to go if condition checks out.
• 3–5 years old — acceptable only if it's been stored well and looks perfect.
• Older than 5 years — the EPS foam has likely degraded. Don't buy.

Manufacturers recommend replacing helmets every 5 years regardless of condition. That's not a sales gimmick — it's material science.

Inspect the shell

Look at the helmet in bright, natural light:

• Cracks — run your fingers along the shell feeling for hairline cracks. Any crack means the helmet has absorbed an impact and the shell is compromised.
• Dents or soft spots — press firmly around the top and sides. A spongy or soft section means the liner below is crushed.
• Deep scratches — light cosmetic scuffs are fine; deep gouges that expose the shell material are not.
• Warping — if the shell is warped or the visor won't seat properly, it's been damaged or heat-treated.

Check the EPS foam

Open the liner and look at the styrofoam layer underneath:

• Cracked, crushed, or compressed foam — automatic reject. The foam does the actual impact absorption, and once compressed it's done.
• Fingerprint-like indentations — a common sign the helmet has been dropped.
• Discolouration or brittleness — foam that's gone yellow or crumbles when touched is degraded.

Inspect the liner and strap

• Liner condition — original, complete, and in good shape. Removable liners are a plus.
• Chin strap — check for fraying and make sure the buckle clicks solidly.
• Visor — must close firmly with no leaks, and the visor mechanism should feel solid. Fogged or scratched visors can be replaced cheaply — don't reject a helmet over a scratched visor.

The fit test (do this before buying)

Even a perfect helmet is worthless if it doesn't fit:

1. Slide it on — it should be snug with no rocking.
2. Cheek pads should press your cheeks.
3. Shake your head — the helmet should move your skin, not slide on your head.
4. Wear it for 10 minutes — pressure points on the forehead are a dealbreaker.

A used helmet in the wrong size is not "close enough." Never compromise on fit.

Verify the ratings

Check for the safety stickers — IS 4151, ECE, or DOT. If the rating stickers are missing, the helmet may have been painted over or the stickers removed. Cross-check the brand and model to confirm it was sold with a certification. See our helmet safety ratings guide for what each rating means.

Where to buy used helmets safely

The best source of used helmets is another rider — someone who can tell you its full history and who wouldn't sell damaged safety gear. A marketplace that connects you directly with the seller, like Biker Bazaar, lets you ask those questions, see real photos, and inspect the helmet in person before paying.

Red flags to walk away from

• Seller can't say how old it is or where it was bought.
• Seller claims it was "only dropped once" — a crash is a crash.
• Stickers removed or shell repainted.
• Suspiciously cheap premium brands (fake helmets are everywhere).
• "No negotiations, fixed price" for an item with visible wear.

The bottom line

A used helmet is a great deal only when it's less than 5 years old, crash-free, structurally sound, correctly rated, and — most importantly — fits you. Check all five and you've found a bargain. Miss any one and you've bought a hazard.
