    My understanding is, it's the polystyrene inner that loses its properties over the years. It won't absorb an impact as well when it's old. A glass or carbon shell will last decades. That's not the bit with the shelf life. The inner is also the reason not to re-use a lid that's had a knock. The polystyrene only deforms once, it'll be your skull the second time..
    Do us all a favour, by bringing yourself up to speed, before pulling onto the motorway.

    Agreed, with the proviso that the shell of the helmet is like an egg shell, it only works once.

    Ah, I missed the Firth of Thames bit. A few years ago I was riding down the Thames Coast as the sun was setting behind the hills. I only had a clear visor with me, and after a few minutes of being intermittently blinded by the sun, parked the bike and waited for sunset.

    Riding in an Westerly direction anywhere into a sunset has the same effect. If you know it's going to happen ... stop earlier for a coffee (or whatever) and wait for the dark.

    The dark will probably require another layer of clothing anyway ... and after a coffee/feed/pee ... you'll be ready for the night ride.

    Regardless how much they cost ... or how often you replace them ... they're cheap insurance.


    $10 heads fit in $10 helmets.

    Your head ... and your helmet.

    SO ... it's YOUR choice to determine how much you should spend on a new helmet ... and how often you need replace them ...

    Ah yes. Reminds me of a Californian I once worked with. He'd bought a 1927 Harley Davidson twin and asked me where he could get a really cheap helmet. I explained the $10 helmet, $10 head thing. He replied. "Oh no. It's not for me, it's for the wife."

    It's not just the setting sun, it's also the reflections off the water and the shaded, blind corners. I completely understand where Blackbird is coming from.

    My understanding is the genuine visors meet an impact standard that cheaper ones dont. Im not 100% on that but it would seem correct. I think its something about they dont shatter. Arai are the same and there visors are very expensive.

    These days I tend to wear sunglasses as well.

    In many places you can find advice on the conditions you should replace your helmet.

    This is one of them.

    https://helmets.org/replace.htm

    Feel free to read ... ponder on ... adhere too ... or simply ignore.



    If it's your head in your helmet ... the choice and responsibility is entirely yours.

    It is unfortunate for glasses wearers but helmets move around a bunch in an accident. Face furniture can cause injury inside.
    I've been told. Dreaming`s free.
    Think I'll go, back to sleep.

    No, but the visor isn't always down when I'm moving. I'd rather some protection when it's not down.

    I've ridden through a swarm of wasps once (visor was down) so it's just another layer of protection.

    Three impact standards in the US according to this info from the Shoei website: https://www.shoei-helmets.com/techno...echnology.html

    There will be an EU standard as well.
