um.... I can't find any stickers on my Shoei XR-900. There's a warning sticker on the inside, that's about it. I bought it from someone in England which probably explains that.

Chemical Decomposition of Helmets

Motorcycle helmets are generally composed of a kevlar, fiberglass or carbon fiber shell and an expanded polystyrene (EPS) foam. Provided it is not exposed to excessive salts (think salt water) or carbon (don't roll around in carbon rich soil or bathe in milk?), the shell is pretty slow to lose structural integrity. However, the EPS will start to break down almost immediately.

Most people know that polystyrene (styrofoam coffee cups, etc.) takes a really long time to fully decompose in a landfill--it takes approximately 10 million years to fully decompose. However, it would only take 100 years for your motorcycle helmet to become a pile of styrofoam grains--sand. So, over a period of 10 years, that helmet is already 10% dust. Not something with good structural integrity much less something you really want to trust with your brain.

When originally determining acceptable helmet parameters, the helmet should meet the standard DOT requirements or whatever similar certification. However, many of these standards do NOT provide standards for old or used helmets. The failure rate for a helmet that is not OVER-engineered will increase as the foam decomposes.

Wearing an old helmet is like using old tires on your car. It is up to you to decide if you want to take the chance. But I can guarantee you that some people who know more about the failure rates than anyone here decided that 7 years is long enough, and I would be willing to bet that that is even longer than is a good idea. They don't want to throw out old stock any more than you want to buy a new one, and at a small failure level they are just fine with paying the settlements rather than throwing them out. YOU, however, only get one head.

I replace my helmets 5 years from the build date, but to each their own. They need to write an updated article backed up with hard data.

never had any idea about the 5 year DOT rule and i'm riding my 5th bike. Maybe less riding and more reading is in order ;)

I found a Shoei X-12 on CL for $300, production date shows M/2010. Do you guys think it's worth it? Moeman? I wish we can tag people in our posts lol.

Some race orgs have a 5 year life span on a helmet from manufacturing date. Just gotta check the rules for that particular race org.



Any info would help guys. Thanks in advance.

here's another thing
how many of you rest your $800 lid on top of your tank when you park your bike ?


here is an experiment

take a styrofoam cup and fill it with a TBS of gas and see how long the cup lasts


that's what you're doing to your lid but resting it on your tank

This is a great article, how have I not seen this before... definitely not worth the risk if you ask me... common sense says it's easier to replace your helmet than your head... ha
