they basicly say the material break's down and you loose support and integrity of the helment over time..

Funnily enough, Tyre manufacturers say the same, 5 year shelf life.

They have to cover their a**ses because once an item of safety equipment is sold, there is no control over its use or storage which could cause the original materials to degrade. Remember helmets are tested and certified on a new item. I bet you won't find anybody who has tested the same helmet several years down the line who will tell you if it still meets the spec. or not.

The way the legals are written these days, you can more or less expect manufacturers to waiver any responsibility the first time a helmet is worn.

Material using lightweight polyester/polycarbonate and carbon fibre with polyester compounds might degrade under certain circumstances. Ultra violet is one of them, also being gouged or dropped. If these materials are submerged in water for long periods they are likely to weaken. How often do you do that?

I'm glad I didn't think I had to replace my glassfiber boat after 5 years, when I bought it 15 years ago - that has a composite hull which takes a hell of a pounding.

I suspect the problem with helmets has less to do with the shell if you look after it and more to do with deteriation of the holding straps, buckles and where they attach.

I have been wearing Shoei helmets for 30+ years. Some years ago, I learned that they offer a free helmet inspection service. Since I moved back to Southern California, where their US headquarters are located, I have taken advantage of that free service several times.

Having used that service several times, I learned a few things from them:

1. They recommend replacing helmets ever five years. There is an age limit where they won't certify a helmet, period. I believe that age is seven years. (By the way, they make you sign a form acknowledging their inspection. You can't claim later that you didn't know your helmet had an issue if they find one.)

2. According to Shoei, a helmet's life-saving, shock absorbing materials lose their protective abilities over time. The primary cause is exposure to the stuff in the rider's hair - perspiration in particular, but also chemicals from shampoos, conditioners, sprays, colognes, etc. Ambient air pollutants also contribute. Washing your helmet liner frequently will slow that deterioration down.

3. Shoei frequently finds latent damage to the helmet's shock absorbing materials during their inspections. They found it in one of my helmets, so I replaced it soon after. A common cause is exposure to heat. In the case of my helmet, I believe it was that the helmet lock on the side of the motorcycle put the helmet too close to the muffler after riding.

4. Casually dropping a helmet is usually not the cause of latent damage, just cosmetic damage to the paint.

My last helmet was probably 7 years old when replaced, but it was stored for at least 3 of those. I probably won't go that long again.

I once heard the following reference. The EPS foam in most helmets can be considered similar to a styrofoam coffee cup. How do those look after a few years? Would you trust your noggin' to it? How much is the cost of the helmet spread over those 5 years?

I was happy enough with my old helmet, but I was even happier with the new model.

I usually replace helmets after 2 or 3 years. The styrofoam liner is the reason. It only last so long and does compact over time. I think Nolan's, which I am currently wearing, have a 5 year warranty, and at right at 3 years old it is still holding up really well. With the current prices, I will probably think about replacing it at about the 4 year point.

I daily ride so I replace my helmets often, I have often been told of the 5 year rule but after 3 or 4 years I don't want to put my head in that helmet anymore

For my wife it about 6 or 7 years between helmets since she does not ride with me often.
