Depending on the conditions id say it will be safe to follow the guidlines, also use common sense, but for someone to say they dont know what they are saying is abit ill advised.Wise words lurch, blindly following guidelines from manufacturers is a dangerous thing to do.
If my helmet is used daily I will certainly be changing it well before the 5 years are up.
You cant get to the inside of my helmets shell without fully destroying it in the process. unless you just mean the padding and not the shell.Got told that age and cracks on the inside of the helmet is the most important by some racers.
The outside can look shite but it inside has cracks in the paint, then it's a bin job.
They say every three years. I, personally but a new helmet every year. I have 7 now . Just picked up the new Shoei -1200. It's the most expensive helmet that I have ever purchased. I can say, that, yes. One cannot compare it to a 200$ scorpion or equivalent. It was a lot of $$$, but you get what you pay for in this case.If there is no fall damage inflicted to a helmet, HOW OFTEN might one need to change out their old helmet? Do the materials in the helmet come apart from one another? I'm not really sure.. I have never crashed in the current helmet that I own, but it's like 5 years old and used daily... Any thoughts on when someone might need to invest in one? Also, I'm not sure if it would be helpful/hurtful to be in the HOT Arizona heat for a lot of the time.
This is a great idea for insurance companies IMO. Knowing that you get some kind of return when it is time to replace your helmet may persuade more people into wearing them.in some countries they offer some sort of voucher/tax relief or return system for the used helmet so it's not expensive to change helmet.
