Good revenue stream for the Mfg. Why would it go bad if it wasn't in a crash or dropped?

 

Harley dealers recommend every 6 months.

Man, times are tough out there and they need the revenue.

 

3-5 years depending on use is what I was always told. I thought it was a scam to replace helmets, but enough different sources I investigated, confirmed the 3-5 year service life.

 

So all you folks out there are saying i should replace mine after 15 years of service

 

I will have to get the cycle world study they did on helmets. It really calls into question many of the ideas we have about helmets. In a nutshell, snell will only help you if you are a twenty year old athlete. If you are an old fart the impact will still kill you dead, but you will look pretty in your new box.

 

If you can factor in use, mine should last me for another 50 years.

 

Three to five years is what I've heard. The oils from your hair and skin break down the foam padding. As with everything things get brittle as they get older.

 

It's your head.
