Helmet shelf life?

I have 2 identical helemts, the Shoei TZ-R. One of them I use, the other sits in its box on the shelf in the garage. I know it is recommended to replace your helemt every 5 years or so. Will the helmet that never gets used still be good or will it need to be replaced at the end of 5 years as well?

I think the 5 years is recommended for if you are using it, but I wouldn't let a helmet sit around for decades before using it either.

The five year replacement recommendation is based on a consensus by both the helmet manufacturers and the Snell Foundation. Glues, resins and other materials used in helmet production over can affect liner materials. Hair oils, body fluids and cosmetics, as well as normal "wear and tear" all contribute to helmet degradation. Petroleum based products present in cleaners, paints, fuels and other commonly encountered materials may also degrade materials used in many helmets possibly degrading performance. Additionally, experience indicates there will be a noticeable improvement in the protective characteristic of helmets over a five year period due to advances in materials, designs, production methods and the standards. Thus, the recommendation for five year helmet replacement is a judgment call stemming from a prudent safety philosophy.

While this is an excellent answer, it does not however aswer my question about a helmet that is not used and not subjected to any materials as listed above that could potetially breakdown the protective material.

I would think that the synthetic materials would still break down over time, used or not. You're not going to find a retailer trying to sell a helmet with a manufacture date of 1999, claiming it's ok because it's never been used.

An "expired" helmet is better than no helmet, and in the end it's a judgement call...

+1- What he said. Maybe I'm anal retentive (I used to wear both a belt & suspenders with a suit!) but I keep my lids in the house away from temperature fluctuations and NEVER leave it outside on my bike. Direct sunlight, heat, humidity, etc can effect the materials. Just don't go out and test any of these theories

Hmmm. They should hermetically seal helmets, just for that situation. I say sell the spare.

My POV on this. I get a new lid every year. Sometimes I sell the old ones, sometimes I give'em away. Strange thing is I have four lids right now. The oldest is almost 4 years old and very little use. Stored inside in great shape. I wouldn't think twice about using it. I just don't. However, it is for sale.

I gave my fisrt one away to some dude on a lowered ZX12R. He was rolling around in a damn dirt bike helmet. He was a pretty big squid too. I didn't pay much for the helmet, so I didn't mind. It was about 2 years old.

That's a good look... Sorta like those guys I see rollin' 80mph wheelies shirtless, in shorts, and wearing Scott motoX goggles with no helmets. 'Dude, I wish I could be as cool as you.'

Those guys are either huge idiots or they have the biggest balls in the world.
