Riding gear is built to die so you don't. A helmet liner crushes, an armor pad deforms, an airbag spends its gas, a leather panel feeds itself to the asphalt. After that, it's a souvenir, not protection. The hard part is knowing when the line was crossed, especially when the damage hides inside the foam.
Here's what Snell and the gear makers actually say. No folklore. For the bigger picture on how gear is rated, start with our motorcycle gear protection hub.
Do you really have to replace a helmet after a crash?
Yes. If your head was in it when it hit something, it is done. Snell's position is blunt: if the helmet has been involved in an impact while in use, replace it, because even good helmets cannot provide adequate protection the second time.
Blame the EPS (expanded polystyrene) liner. Snell explains that in an impact the head crushes the EPS against the shell, and that crushing slows the head gently instead of letting it stop abruptly. The liner absorbs the shock by collapsing itself. Collapsed foam can't do it again, and you usually can't see where it gave way.
Manufacturers agree. Shoei Europe states a helmet must always be replaced after a fall or accident, even with slight or no visible traces, because it is built to absorb a single impact. Bell's crash replacement page reminds riders to never wear a helmet that has been involved in an accident.
What if you just dropped your helmet?
It depends who you ask; the experts don't fully agree. Snell says a drop from your hand or the seat generally doesn't require replacement, but frequent dropping or "spiking" a helmet on hard surfaces may eventually degrade it.
The UK government's SHARP program is stricter. SHARP says a helmet that falls onto a hard surface should be replaced as soon as possible, and one falling off your seat onto pavement "is not likely to be ok." Shoei Europe says a visibly damaged shell after a drop means immediate replacement.
Our read: carpet drop, shrug. Seat-to-pavement drop or anything that leaves a mark, get it inspected or retire it. Snell admits that without a trained professional's inspection, damage can be hard to spot.
Some brands will look at it for you:
- Shoei (U.S.) runs a free impact inspection service with Helmet House for helmets still under warranty (5 years from purchase or 7 from manufacture) bought new from an authorized U.S. retailer. Shoei warns most submitted helmets are not approved, and Helmet House doesn't X-ray them.
- Arai says on its warranty page that a helmet with any doubt about its ability to protect should be returned to the manufacturer for inspection or discarded and replaced.
Where does the five-year rule actually come from?
It's a judgment call, not physics. Snell calls it a judgement call based on testing helmets used by the California Highway Patrol, and recommends replacement after five years of normal use.
Snell's reasoning is mostly about fit. Putting the helmet on and off wears the comfort pads and foam liner, and Snell says helmets with worn-out pads are at least one to two sizes larger than new. A loose helmet is more likely to shift or come off in a crash. Snell also says unused helmets stored in good condition do not automatically expire after five years.
The makers put their own numbers on it:
- Shoei: Shoei Europe recommends replacement after about 5 years of normal use. A Motorcyclist Q&A quoted Shoei as five years after purchase or seven after production (date sticker under the padding near the ear), with the seven-year cap accounting for the EPS liner's useful life, worn or not.
- Arai: the warranty runs 5 years from first purchase, capped at 7 from manufacture, and Arai repeats Snell's advice to replace within 5 years of first use.
- SHARP: says manufacturers recommend 3 to 5 years, and to plan on five or sooner, since the lining compresses and the fit loosens.
So the clock is real, but it's cautious guidance. A helmet ridden daily through Montreal's freeze-thaw circus earns retirement faster than one living in a closet.
What signs of wear mean your helmet is done early?
If the fit, liner, strap or shell has changed, don't wait for a birthday:
- Fit. SlashGear's rundown suggests a simple test: wear it, fasten the strap and give your head a shake. If it twists around or doesn't fit like it used to, it's time.
- EPS liner. Per Shoei's guidance quoted by Motorcyclist, replace regardless of age if the liner separates from the shell, starts to break up, or has been exposed to solvents or enough heat to melt it.
- Shell and hardware. SHARP lists cracked plastic parts, fraying fabric and foam that crumbles with age as signs, and notes shell cracks may not be visible. A frayed chin strap or cracked retention hardware is exactly that kind of failure.
- Visor. Shoei Europe says to replace the visor after 5 years at the latest, and to replace scratched or irreversibly soiled visors immediately. Night riding through a scratched shield is a horror film nobody asked for.

Does body armor need replacing after a crash?
Yes, if it took a real hit. D3O's care instructions say a protector that suffered a sustained blunt impact should be discarded and replaced, and protectors should be inspected for wear before use.
Knox goes further: protectors that have received an impact in an accident should be replaced immediately unless the manufacturer confirms they are fit for use, they should be inspected at least annually for wear or broken stitches, and Knox advises replacing them every 5 years regardless of condition.
D3O also says never fold its protectors, never use detergents on them, and store them dry, at room temperature, out of direct sunlight. A hot saddlebag all summer is not a storage plan. Our motorcycle armor guide covers CE levels for replacements.
What happens to an airbag vest after it deploys?
It stops protecting you until it's serviced. Details vary by model, so read your manual.
- Alpinestars Tech-Air: Alpinestars says that after deployment, airbag protection is unavailable until the system is serviced and the gas inflators are replaced by an authorized service center. Users can also swap canisters with original spare parts, per the manual and only in authorized countries. The system also must be serviced at least every 2 years or after 500 hours of use, crash or no crash.
- Dainese D-air: on Dainese's model comparison, the Smart Air's gas generator can be replaced by the owner, with the airbag itself replaced by an authorized D-air center after the third deployment. The Smart Jacket needs an authorized center at every deployment for both the generator and the airbag.
- Dainese mail-in service: for bag replacement, Dainese inspects the garment and any leather or fabric damage first, quotes 2 to 4 working weeks, and may suggest replacing the whole product if damage is extensive.
More on how these systems work in our airbag vest guide.
Can a leather or textile jacket survive a slide?
Sometimes, with professional repair. The shell's job is to wear away so your skin doesn't, so inspect it like a crime scene.
Check shoulders, elbows, hips and knees for abrasion through the shell, then seams, armor pockets and liner. A jacket that can't hold its armor in place has lost the point of the armor. Burst seams or holes through the shell mean pro repair or retirement. Scuffs on thick leather are cosmetic; worn-through patches are not.
Some makers repair crash damage. Aerostich sends an itemized estimate before work begins and considers a suit "totalled" if repairs would exceed half the price of a new one. Repair the jacket if you like, but replace any protector that took the hit.
Which brands offer crash replacement programs?
A few do, with narrower terms than the marketing suggests. These are the ones we verified on official pages:
- Klim Gear Protection Guarantee: under the current terms, effective February 1, 2026, "Pro Shield" products (including select helmets such as the X1 Alpha, GT1 Expedition and Krios Pro, plus certain jackets and pants) are covered for 5 years from purchase, at 100% replacement with an official police report or 50% without. "Ride Ready" products get 2 years at 50% with a report or 25% without. Original purchaser only, proof of purchase required, one redemption per purchase, and accidents from illegal or reckless activity (e.g. DUI) are excluded.
- Bell: the crash replacement program offers a discount on a new Bell helmet, not a free one, and is limited to U.S. customers. You email the model, serial number, manufacture date and damage photos. Outside the U.S., Bell sends riders to their local authorized dealer, so Quebec riders start there.
Shoei's U.S. inspection is a check, not a replacement, and Arai's warranty excludes accident damage. Whatever you ride, photograph crashed gear first; these programs ask for photos.
What should you do with old gear?
Make sure nobody else wears it. As RideApart points out, helmets mix materials recycling plants can't easily separate, so your blue bin probably just sends it to the dump. Don't sell a helmet you retired for safety reasons, and cut the chin strap before it goes in the trash so nobody fishes it out thinking they scored a free lid.
The best exit is donating it to first responders, whose training programs may use it to practice handling crash victims. Leave the strap intact for that. Otherwise, it can live on as décor. A cracked lid on a shelf makes a fine memento mori. It's the only good reason for a helmet to sit beside the espresso machine instead of on your head.
