A motorcycle helmet doesn’t have an expiration date stamped on the shell. It still looks fine. The visor still moves. The chin strap still buckles. None of that means it’s still doing its job.

Here’s how to tell when your helmet has reached the end of its protective life — and why “looks fine” isn’t a safety standard.

Rule 1 — The 5-year rule

Most helmet manufacturers — including the major safety organizations like the Snell Memorial Foundation and ECE testing bodies — recommend replacing a motorcycle helmet every 5 years from the date of first use, or 7 years from the date of manufacture if it was stored unused.

Why 5 years?

• EPS foam degrades. The multi-density EPS impact liner that absorbs crash energy slowly breaks down from heat cycling, sweat, sun exposure, and chemical contact (oils, hair products, cleaning agents). It loses its ability to crush predictably.
• Adhesives fatigue. The bonds holding the comfort liner, padding, and shell components weaken over time.
• Plastics oxidize. The ABS shell and polycarbonate visor become more brittle with UV exposure year after year.
• Chin strap weakens. Webbing, micrometric buckles, and D-rings all wear out with use.

The helmet still looks like a helmet. It just doesn’t crash like one anymore.

Rule 2 — The after-impact rule

If your helmet has been in any crash — replace it. Period.

EPS foam is designed to do its job exactly once. It crushes, absorbs energy, and then it’s spent. The crush isn’t always visible from the outside. The shell can look pristine while the foam underneath is compressed and useless for any future impact.

This rule applies even if:

• The crash was at low speed.
• You only “tipped over” at a stop.
• You dropped the helmet from chest height onto a hard surface (concrete, tile).
• It rolled off a seat onto pavement.
• It got hit by a bag in the trunk during a drive.

No, soft drops onto carpet or grass don’t count. But anything that involved real impact energy means the helmet is done.

Rule 3 — Warning signs before year 5

Even before the 5-year mark, replace your helmet if you notice:

• The fit is loose where it used to be snug. The interior padding has compressed past its useful life — the helmet won’t stay on your head correctly during impact.
• Visible cracks in the shell or EPS liner. Any crack is the end of the helmet. No exceptions.
• The chin strap stretches, frays, or the buckle gets sloppy. A helmet that comes off in a crash is the same as no helmet at all.
• The visor mechanism fails. If a flip-up chin bar won’t latch, or a visor pops up at speed, that’s a safety issue.
• Persistent bad smell that won’t wash out. Means bacterial growth has made it past the comfort liner — the foam itself is contaminated.
• Heavy UV fading on a previously matte shell. The shell material has been compromised by sun exposure.

“But it looks fine”

A helmet’s job is not to look fine after a crash. Its job is to absorb a single, severe, head-first impact and keep you alive. The helmet shell is designed to spread force across as much surface area as possible while the EPS foam compresses to slow your head down over a critical few milliseconds.

A helmet that’s already absorbed an impact, or whose foam has aged out, can’t do that work the second time. The shell will still fly off and look intact at the side of the road. You won’t be intact under it.

How to track the date

Most helmets — including every EDGE® helmet — have a date of manufacture stamped or printed inside the chin strap or on a tag sewn into the comfort liner. Pull the cheek pads or comfort liner out to find it.

When you put a helmet into service, write the in-service date on a small piece of tape on the inside of the shell. Five years from that date, replace it.

Crash replacement

If you’ve been in a crash while wearing an EDGE® helmet, contact us at support@edgehelmetsus.com. We offer a Crash Replacement Program — ask our team for current details on the discount on a same-model replacement.

Disposing of an old helmet

Don’t put a retired helmet back in the rotation as a “loaner” or hand it to a kid as a costume prop — once it’s retired, it should not see another road. Cut the chin strap, mark the shell with a permanent marker, and put it in regular household trash.

Some local recycling centers accept helmet components. Check your municipal recycling program before dropping one off.
