Hey up I've just passed my das got myself a bike was just wondering how long does a lid last I've had a agv lid for 7 years and never used it till last weekend is it still safe or do I need to get a new one it may be a daft question but I really don't know cheers

generally going to be too old. If it's plastic then way past it. If it's an expensive carbon fibre one it might have a bit left in it.... might.
The reason is that the shells become more brittle with time and thus the protection is markedly reduced.
Ok cheers mate looks like a new one for me then
buy a new one - what price your life n'all that.
is 7 years really too long?
I know plastic depreciates within 3 - 5 years with UV damage, but if it's been tucked away unused surely it shouldn't have any UV damage.
I could be wrong but just on the safe side I'd buy a new one, they're only like £45
I replace mine every 3 years
only because I'm not always that careful where I put it, so for a small investment I prefer to be overly cautious
Drill some holes in it
and use it as a hanging basket
Fortes Fortuna Adiuvat
actually made me chuckle, what a novel thing to do lol
.... or put it at the bottom of the garden, so hedgehogs or similar can use it as a home.
ALL cars are crap, but some are more crap than others.
NO £45 Helmets
stbrewer, flippin heck is your head only worth £45 quid? Buy the best you can afford and a well known make with a gold sticker. Not all makes fit all head,s but try a load on and see what make suits your head shape best. I like agv and you can get a decent one for about £130. I bought mine after writing on an arai. This winter I'm going to try buy myself another arai, but they really are dear. Best you can afford is what I think. And look after it because when it comes down to it, it could save your life. If it wasn't for my last helmet my brains would have been splattered across 3 lanes of a busy road in argyll & bute.
Your heads worth more than £45.
Oh and like the hanging basket idea
When it comes down to it that's the only thing between your head and the tarmac, £130 polystyrene is pretty much the same as £45 polystyrene. mine has the gold sticker and the E numbers so I'm pretty confident I have a reasonable amount of protection, its a no frills helmet and no one in MotoGP wears it, hence being dirt cheap.
But yeah if I had the cash I'd want more protection but with a max speed of 50mph and a students wallet I'm pretty content on my lid.
Love the hedgehog idea though, no home for wildlife there will be no wildlife and all that
Testing is the difference in price. Bigger brands, put more money into testing. Cheap brands are cheap for a reason. I understand cheap gear and cheap bike on a student budget. I've been there myself. I'm just glad by the time I had my big bin, I had a better helmet. I was still knocked out and suffered swelling on the brain, but I dread to think what could of been with a cheaper helmet.
I now treat my helmet very well. Clean and polished and out of reach of my son.
True life savers
Before I upgrade my bike I'm going to upgrade my helmet, I agree that the bigger brands test more, if they didn't it would be virtually criminal and I fully agree you wear a helmet for one reason and that is to save your life. But at the moment I can't justify £100 more for a helmet with a better brand on it especially when they have the same credentials.
I don't intend to spend my life in cheap helmets but for the time being I suspect I'm doing alright. But anyway back on topic I am curious about the depreciation of a helmet but I guess it's how long is a piece of string right?
I you're throwing an old helmet away
try your local Fire station first. They are often pleased to be given them to use in practice sessions.
I know I ride like a girl. So try and keep up.
of manafacture should be no later than two years for racing ..............tells you something
All I can is my £250 arai condor that had 2stars sharp raitng down to the wire at a 30mph slid so I dread to think what would of happened at higher speed. I won't ever buy another arai again. I now use a shoei at it fixes well and has a 5 star rating. And my £50 box lid has gold sticker on the back. The gold stick mean nothing when buying helmets. As a cheap lid has them on.
I can't change my above post
The helmet went down to the wire at 30mph slide
Yes , i agree with you dude, really good suggestion..
some £45 are better
actually 5 star SHARP £45 helmet is better than £500
There is EU study and it is proven fact that some high priced brand
helmets are too hard and do not absorb well crash energy - means they
are very dangerous in everyday riding crashes.
Which means that £45
pounds decent helmet that has passed EU certification will be much better
than £500 one that has passed SNELL.
Forget about all this snobbish nonsense about Arai, Schubert or Shoei they are no better than Caberg, Duchini, G-MAC or Lazer.
Not to mention that the most important feature for any helmet to protect you is the good fit. Different people have different shape heads so the only way is to go and try which one fits better for your head.
Here are the facts (my citation from): http://www.motorcycledaily.com/2012/01/rating-helmets-beyond-passfail/
what I've read, the Arai's don't do well in SHARP testing because they
have been designed with the SNELL tests in mind. The SNELL tests are at
higher G's and they test how well the helmet does in multiple hits in
one area. To pass those tests the helmet has to have stiffer linings,
which means that they have less give in lower speed hits. So doing well
in SNELL trades off high speed safety for real-world lower speed safety.
SNELL helmets may be better for racing, but ironically lower priced
helmets with softer linings might be safer for street riding."
It is a matter of the amount of energy absorbed by a helmet at various speeds. According to this article:
"The European Union recently released an extensive helmet study called COST 327, which involved close
study of 253 recent motorcycle accidents in Germany, Finland and the U.K. This is how they summarized
the state of the helmet art after analyzing the accidents and the damage done to the helmets and the
people: 'Current designs are too stiff and too resilient, and energy is absorbed efficiently only at values of
HIC [Head Injury Criteria: a measure of G force over time] well above those which are survivable.' "
in other words, SNELL helmets are designed with an eye towards dealing
with impacts where the rider isn't going to survive in any case, at the
expense of doing a better job of dealing with impacts that are
survivable. In the case of lower energy, survivable impacts, SNELL
helmets don't do as well as helmets designed with an eye only towards
ECE and SHARP.
I suggest that everyone read the cited article."
As I have said do not always trust manufacturers, SHARP rating is independent testing and it is the best one known so far.
Unless I'm wrong, which, you know, I'm not...
"Randy says, 'From what I've read, the Arai's don't do well in SHARP testing because they have been designed with the SNELL tests in mind. The SNELL tests are at higher G's and they test how well the helmet does in multiple hits in one area. To pass those tests the helmet has to have stiffer linings, which means that they have less give in lower speed hits.'"
I think Randy is wrong in that the SNELL road helmet tests are at lower g than SHARP, and it's SHARP which tests multiple hits in the same area. Thus if you claim that some cheaper helmets are safer because they work better at real-world, single hit, lower-g impacts the SHARP test data doesn't support that. The SHARP test says peak acceleration in excess of 500 g is the gold standard, but anything getting 5-stars, be it £45 or £450, must be too resilient by that argument. Experts now suggest a more realistic value would be 300 g or less, which I believe is the SNELL gold standard for road use.
I don't consider the SHARP (or SNELL) rating at all when buying a helmet. I understand that SHARP has 6 impact zone colours for discrete brain acceleration values but I don't know how this translates into 5 star ratings. This is a classic (and perhaps rare) case of racing improving the breed so I personally trust Arai's R&D more than these arbitrary tests. Ask yourself how good a job you could do given £45 to make a helmet. Not much, I'd say, unless you're after breeze-block levels of impact resistance with no other regard.
It'll be well past it's use-by date by now; this is a two year old post!
