The general rule is to replace your motorcycle helmet every five years, but what if you drop it, sweat heavily or wear it every day?
The biggest myth is that if your helmet falls off your bike when it’s parked, you should change your helmet. That’s probably put around by helmet retailers.
Certainly you should check the helmet and it might depend on how far it fell and rolled. However, even though helmets are a one-use product designed to protect you in a crash and then get thrown away, they are pretty robust.
At least the helmets allowed in Australia are robust, especially now that UNECE 220.5 helmets are permitted.

However, I wouldn’t trust some SE Asian helmets if they fell on a feather pillow.
Most helmets will easily withstand the general knocking they get in daily life. If they don’t, then you really have to wonder about their ability to protect you in a crash.
If the helmet you bought isn’t able to handle the crash well and if you are planning to buy another one then consider checking out the safest motorcycle helmets of 2020.
Show some respect
That doesn’t mean you can throw your helmet around. You need to treat a helmet with respect and care and store it in a cool, dry place.
The outside shell – plastic, fibreglass or carbon fibre – is pretty tough, but keep it away from petroleum-based products such as fuel, cleaners and paint.
It’s the interior foam that deforms to absorb the impact in a crash and protect your head. So that means that you shouldn’t store any heavy objects in your helmet. If it drops with something heavy in it, then it will damage the helmet.
Also, be careful how you hang your helmet on a hook as this can deform the interior foam.
If you feel the need to inspect a helmet after you’ve dropped it, you could probably get it x-rayed by a professional. However, if it’s been such a big drop or a frequent number of knocks that you are concerned, then you should just bin it anyway.
General helmet use means a helmet will last for about five years. The glues, resins and other materials used in the making of the helmet can lose their effectiveness and also deteriorate the lining.
Be aware that your helmet may have sat on the shelf for some time before being bought by you. Ask the dealer to prove date of manufacture.
You can prolong your helmet if you store it properly when you’re not using it. Keep it in a cool, dry place and store it inside the helmet bag in which it came.
It’s not the outside that deteriorates, but the inside foam and fabric lining. If you notice the helmet getting loose or some of the lining coming out or it leaves little black flakes in your hair, then it’s time to retire it, whether it has reached the five years or not.
Frequent use, sweating in your helmet, having greasy hair or using a lot of “hair product” can all aid in compacting the foam and making the interior lining degenerate faster than normal use.
You can also prolong the life of your helmet interior by wearing a helmet liner, balaclava or scarf that keeps the sweat off.
Another good reason to replace your helmet every five years is that helmet technology is advancing all the time and a new helmet is going to offer more protection than something five years old.
