If you are interested in finding some good deals on bike helmets then
have a looksee here:

Sorry, can't see any helmets at all there. All I can see is a bevy of links
to crapware sites.

I think you misspelt "**** off spammer bitch!" there, Bob...

There is an article about the safety of Helmets in the current edition of
Roadrider Magazine, a bit of food for thought but will probably make no
difference.

What is the article's main point?

Recently a bunch of Snell rated pushbike helmets were tested. Not one
passed the Snell testing.

A bunch of AS rated pushbike helmets were tested to AS standards. They
all passed bar one, which was found to not be in the list of tested lids
- that is the AS sticker was fraudulent.

I wonder what the results would be if done on motorcycle helmets...

I believe that Snell testing is done by the manufacturer sending Snell a
sample of 5 helmets they say are typical of the model. And every batch
of that model gets a sticker.

AS1698 requires helmets from every batch to be tested, and for them all
to pass before that batch gets a sticker.

Which is one of the reasons helmets here are more expensive.

Basically said things like:
- Aus Standards and euro standards are more indicative that the helmet does
pass rules compared to Snell and DOT standards
-The helmet material makes little difference in helmet performance, in fact
plastic helmets were more consistent
-Dropping your helmet does not mean it needs replacement
-Open face helmets have no worse record for injuries than Full face helmets

Basically it shattered a lot of common myths.

Sounds like what I've been told.

THe bod who does the testing for AS1698 is scathing about Snell. He has
also seen no difference in helmet materials as to how well they pass the
AS1698 tests.

He did try a bunch of old helmets, the oldest 12 years old, of varying
amounts of wear, and they all passed AS1698.

I don't think he's tested dropped ones. I seem to recall something like "as
long as your head's not in it and you don't throw it at the concrete"
but that might have been someone else.

THe only stats I've seen for full vs open were on the ATSB website from
a paper that was a bit dodgy in methodology. They covered a bunch of
crashes where someone went to hospital, and looked at the kit, and they
also interviewed people who reported crashing.

They found very few who had hit their heads, and so didn't have enough
numbers to draw any conclusion about open vs full.

AS1698 doesn't test chinbars or any part of the lid below (I think) the
eyebrows.

Another interesting bit was there was no real evidence that those in the USA
who don't wear helmets are no worse off than those that do. As the article
stated something to the tune of ; there is no guarantee that having a
helmet will save your life. You might have the best helmet that money can
buy but that doesn't save you from internal or spinal injuries.Not the exact
words but this is how I interept it.

I don't know whether it's more stupid to state something that obvious,
or to quote it.

Nev..

 

I'm kinda hoping it is the former.......and not the latter!!

....and this one too, Theo.

I believe more than 30 States in the US have so far repealed the helmet law.

AS1698 is, as I understand it, a test of an object being dropped on top of
the helmet at about 20 km/h. That has never happened to me, or to anyone I
know. I suspect it may be of some use if you fall off a bar stool, while
your feet are entangled in the foot bar so that your head strikes the ground
vertically. This would be an impact of that velocity. In my expreience a
helmet will save you from the impact of the dreaded 'large green bug' that
probably would have missed your head had you not been wearing said helmet.

Errm... that's too many negatives for me to follow:
Does that mean that non-helmet-wearers are not less likely to suffer less
injuries or more?

 

A friend of mine (actually my then cousin-in-law) once tried to ride his
Suzuki GT250 when he was pissed-as-a-newt and he put his Arai full-face on
and then slipped and went completely arse-before-tit backwards onto his
concrete garage-floor.
When his wife finally convinced him to give it up he took his helmet off to
find that an area the size of a beer-coaster had caved in like an eggshell.
His is the only case where I can genuinely, hand-on-heart say that wearing
a helmet saved his life.

 

When I pranged the CX, my helmet ended up with all the polystyrene
in the forehead area compressed wafer-thin ... and me with mild
concussion. So I figure it's probably just as well I was wearing it.

----sharks (PS: The shell was only lightly scratched ...)

 

My daughter had a fairly big off when racing an enduro and split the outer
shell from the opening for about 5 inches in line with the right temple. She
also cracked the chin piece in 2 places.

Mild concussion and whiplash - back at school on
Wednesday...............................

When I pranged and spent a week in hospital with brain damage[1] the
helmet was scraped a bit but no obvious damage to the polystyrene.

So I have no idea if it helped at all...

[1] with permanent consequences... but that doesn't explain the Guzzis,
I had them already.

 

Perhaps you should repeat the procedure without the helmet for a valid
comparison.

I can't - I can't remember how I crashed!

So hitting the ground at the same angle would be too difficult.

A new use for speed cameras! Footage of spills for later
re-enactment...

Your head although you need it to live is only a small part of your body.
Its like wearing a bullet proof vest and rushing a machine gun emplacement
and wondering why your legs got shot from under you.

As for the AS test ive seen it on tv I think its the helmet upside down on
an 300 degree angle at 25 something clicks into something resembling an
anvel. If I recall it appeared the front top section took the impact.

I think the theory behind it is that no matter how fast horizontally you are
traveling you will only fall at 9.8 newtons of gravity vertically which was
around 25kph from a personf alling from a bike, basically there saying that
you could be standing still or riding would have the same physics. But I
recon that would be ok unless you hit the ground at 100kph and then slide
head first into a wall.

Its a long time since i done physics, or english for that matter so dont put
me on the AS testing machine if i got it wrong.
