Dropping helmets

I doubt if any damage has occured. To Damage the polystyrene shock absorbing part it would have to be compressed between the head and the shell during impact or the shell would have to deform to damage it. I doubt that dropping it from knee height would deform the shell at all. But having said all that, it's your head and you have to decide whether to carry on using it.

As already said, if you bought it from an Arai dealer then take it in and they will send it away for inspection.

I was taking to a guy in Leeds HG and he said they use some form of Xray type thing. Also went on to say that a Viper GT which had had all the graphic on one side scrapped off in an accident came back as fit for use.

No harm in getting htem to send it in and see what they say. Better to be safe than sorry

Either way I doubt if your lid wes damaged by a small drop like that.I think one of the mags did a test on a few lids and found none of them were damaged by bigger impacts than that.Was it Ride???

+1 my girlfriends parents had there Arai inspected FOC after a low speed off.

arai do free testing on the lids incase you have damaged it if you have the receipt and it's not imported.

I hit my a*s bionic back protector when I crashed I think. it was from about the height of the roof of a car to the road - do I need to replace it?

Think about how the helmet works in a hit - the inner foam part compresses between your head and the hard outer shell. The outer shell doesn't compress in, your head 'compresses' out (or at least, it's not the intention & shouldn't do significantly unless your whole head has been purified).

I have some advice for you. Don't drop it. Hope that helps...

I heard that a drop from bike seat height is the equivalent of a crash at 30mph.

You could work it out, you just need to figure out how fast the helmet will be travelling.

Of course that ignores the (very important) fact that nothing is generally inside the helmet when you drop it off your bike...

Who told you this?

But the helmet does not have the weight of your head in it, gravity will not replicate that at low height.

Personally I would replace the helmet, two big offs and I have never sustained any serious head injury so I appreciate the importance of a 100% helmet.
