At least there is no mandated "expiry dates" on helmets like on child car seats.
right, the time to buy a new one is when you pick it up and it just turns to dust in your handsAt least there is no mandated "expiry dates" on helmets like on child car seats.
For scientific purposes, could you tell us what date is from the manufacturing stamp on the "new" RF1100?I finally broke down and got my new Shoei RF1100 helmet out. Bought while there was still a chance to get my size XXXL. It was the last one in Canada at the time. My old helmet is getting up there in age, probably 8 or 9 years. Tried on the new one and damn that thing is tight... Looked at the foam and the old one is pretty compressed compared to the new one. Didn't help that both the helmet and I got cooked in a 4.5 hour commute a couple of weeks ago when it was over 30C outside. It is getting tossed out. Won't wear it again.

That's a little out of my comfort zone for age. Helmet design has also come along ways since the RF1100 as well.
In a closet, away from uv light, and drastic temperature changes?It's probably still fine, but not really ideal. A lot of improvement has happened in 8 years, and degradation happens even in storage, although a lot slower than while being used.
What I read is that the foam hardens and becomes brittle over time, and then no longer protects your head as well. This is caused mainly by usage (sweat from your head, chemicals from products in your hair, etc) but even with no usage, time still plays a role. I'm just repeating what I read, I'm no expert myself. But when it comes to my head I'd rather err on the side of caution. I think it's a bad idea to buy a helmet years in advance of when you actually intend to use it.
No, what makes you think so?So is a brand new $29.95 piss pot helmet from Canadian Tire safer than my 5 year old Schuberth 3C Pro in good condition?
Depends which foam you're referring to. There's the soft spongy comfort foam that disintegrates from looking at it, and then there's the EPS foam that goes between that comfort liner and the hard shell, which is comparatively indestructible. This is from a bicycle helmet test, but you get the idea: EPS Foam Helmet Liner Performance With Age
My decision is based on my personal experience. My 40 yr old Nava full coverage is about 10 sizes too big because the eps liner has degraded and has shrunk. I have a 25 year old Shoei that is in the same state but not quite as bad. If a helmet doesn't fit properly, it's useless. Not my opinion, just fact.
"You should buy a new helmet every 5 years."
"Says who?"
"The helmet manufacturers..."
Surprise, surprise.
EPS is a plastic and aside from contact with hydrocarbons or exposure to UV from sunlight, it is relatively unaffected by other naturally degrading processes. Geofoam® placed in the ground for decades increased its compression resistance (strength). The lifespan of EPS is long, potentially unlimited.
Styrofoam (more appropriately called Polystyrene or EPS) languishes in landfills indefinitely, taking at least 500 years – and possibly much longer – to decompose.
I would have no issue using the same helmet today .....but bloody claustrophobic.Bell introduced its Star model, the first full-face motorcycle helmet on the market, in 1968. In 1971, Bell produced the first full-face off-road motorcycle helmet.
