How high did you drop the block from? What is the weight of the cinder block? Did you see the flex on the fiberglass helmet? Your skull would have been crushed just as much the poly shell. The only difference is the permanent deformation.
Nevermind. I saw the drop distance in another comment. Your drop height and weight are more than double Snell and European testing. Given the European test dropping a ten pound block from 9-12 feet produced 5000lbs of force, your test could have generated 2-3 times that. Also the impact angle of the block has to come into play as well since a sharp edge would translate all of the force into a smaller area you would expect to see more damage. This "scientific" test only proves what physics already tells us. I would not be afraid to wear either helmet. If you get hit in the head by a 30-35lb block from 20ft your going to die.
The orientation of the block on impact plays a roll here. Would love to see the same experiment with bowling balls or something. Not the the results would nessisarily be that different, it would just remove one more extraneous variable.
The thing is the brick didn't land under the same angle. In the first test there was less surface in contact so less resistance from the helmet. Second test the brick landed pretty flat. Regardless, plastic is obviously weaker.
theyre both rubbish! fiberglass collapsed to 1/5 of its original size and volume. i have a screenshot of the clip in the video of when it does if youd like it
the deformation in fiberglass is at the open area of the view not at the area of the skull that is what we saw and what we want its WAYYYY better than all thermoplastics i am an thermoplastics mould maker believe me if you have to choose go for fiberglass for your safety...
This is absolutely true, thermoplastics are just so much less stiffer even thought they are more tough i assume that just means it will deform/bend for a second and crush your skull while fiberglass is multiple times stronger in actual strength but is not tough so once an impact is too large it will break at certain specified places/ways according to the manufacturers intentions
@@leonordin3052 Any breaking and cracking isn't the problem with the fiberglass, the fiberglass is flexible to the point of collapse but your head isn't.
Holy crap! Looking at the video frame by frame, the fiberglass helmet collapsed downward about 30% until the face opening was no longer visible. The helmet then flexed back to its original shape...but will your head flex back to its original shape??? Next test put a watermelon or styrofoam head in the helmet. Wow....thanks for the video!
I saw an article a long time ago by a big smercan moto magazine.they said polycarbonate actually absorbs better on inpact,kind of like crumple zones in cars.i still buy fiberglass
First you should do the test with a fake head inside. Second, the Shoei resisted as shape, but if you look at 1:44 wit 0.25 speed you see the deformation would have smashed the head in any case.... 3rd when you get such weight on straight on your head, there's no helmet which will save your neck to snap. 4th the angle of impact is different and therefore the force distribution is VERY different, so this test is just useless...
Its not useless. Even though it wasnt scientific in its implementation you can clearly see the strength difference between the 2 materials. There is a reason why fibreglass helmets cost over 350 and you can get polycarbs for 70 dollars
Ya but still, why wear a cheap helmet. That plastic one really is weak, i c what you mean but the stronger shell will stop more of the initial impact. This isnt a very scientific test but yikes that plastic is weak, like just wearing a styrofoam helmet with no shell.
@@usynnstradler Well i bought a Simson Outlaw after watching some of this stuff, Snell rated and as solid as i could find. I have a open face Biltwell for around town though.
The difference is on penetrating impact, it is assumed that your body is not rock solid and your head will be displaced with the impact, you are not atached to the ground...
Totally non scientific experiment, lol. First, the two blocks landed at different angles. Try doing a controlled drop like Snell does if you really want to show how they will react. If one lands on a corner as apposed to flat, the result will be night and day. Second the Shoei completely crushed regardless if it was in a previous accident or not, you would be dead from either. Your test is pretty bogus as you dropped something heavier and higher than Snell does. The impact you're talking about would never happen in real life more than MAYBE 1% of the time and even then you would have to be going about 200, fly off your bike and hit the corner of a curb head on which would kill you anyways from the amount of Gs transferred to your head which Poly helmets do better than fiber glass and carbon fiber at lower normal street accidents. Please stop doing unscientific tests and misleading people, it is dangerous and irresponsible.
Here's what a proper, independent test conducted by Motorcyclist magazine found in 2005. The results are VERY surprising. ...Conventional wisdom has it that fiberglass construction is somehow better at absorbing energy than plastic - something about the energy of the crash being used up in delaminating the shell. And that a stiffer shell lets a designer use softer foam inside, which might absorb energy better. Our results showed the exact opposite - that plastic-shelled helmets actually performed better than fiberglass. In our big, 3-meter hit, the high-energy kind of bash that one might expect would show the supposed weaknesses of a plastic shell, the plastic helmets actually transferred an average of 20 fewer Gs compared with their fiberglass brothers, which were presumably designed by the same engineers to meet the same standards, and built in the same factories by the same people (the test was conducted using plastic and fibre-glass models from the same brand). Why is this? Well, we’re guessing - but it’s a really good guess. And our guess is that the EPS liner inside the shell is better at absorbing energy than the shell. The polycarbonate shells flex rather than crush and delaminate, and this flexing, far from being a problem, actually lets the EPS do more of its job of energy absorption while transferring less energy to the head. Remember, these particular polycarbonate helmets, from both Icon and Scorpion, are also Snell M2000 rated. So they are tested to some very extreme energy levels. And Ed Becker, the executive director of the Snell Foundation, is on record as saying that a low-priced - that is, plastic-shelled - Snell-certified helmet is just as good at protecting your head as a high-priced - that is, fiberglass - Snell-certified helmet. So at the high end of impact energy, we have the Snell Foundation vouching for their performance. And our testing, without the extreme two-hit hemi test, says they’re actually superior. The DOT helmets we had were all plastic-shelled, and none cost more than $100. How did they do? They kicked butt. The DOT only helmets from Z1R and Fulmer delivered less average G force to the headform, through all the impacts, than any others in the test (this included higher-end helmets from Schuberth, Shark, Arai, Shoei, AGV, Scorpion and others...Bell declined to supply helmets for the test). And both plastic lids still excelled in the big-hit, 150-joule impact - a blast 66 percent harder than any actual DOT test for a medium-sized helmet. The Z1R ZRP-1, in particular, continuously amazed us. After all the testing, its outer shell looked essentially unharmed: the slight road rash at the impact sites caused by our stubborn insistence on hitting actual pavement looked no worse than we’d expect if the helmet had fallen off the seat at a rest stop. When we pulled the ZRP-1 apart we saw that the EPS had cracked and compressed at the impact sites, just as it’s supposed to do, and as it did in every other helmet. But it had come nowhere near bottoming; there was still an inch or more of impact-absorbing foam left. And the plastic shell seemed completely unharmed, from the inside as well as the outside, even where it had taken the terrifying edge hit and the big three-meter bash. This illustrates just how hard it is to tell, from the outside, whether a helmet has taken a severe hit. And why you should never, ever buy a used helmet. So the softest DOT helmets came through our tests with protection to spare. But the doubt still lingered, in spite of everything we had seen: How would they do in a monster, wicked big impact? So we decided to kill them. We ran the Z1Rs up the test rig one last time. Not just to the 10-foot, 150-joule Snell test height, but all the way to the top of the rig: 3.9 meters, or 13 feet. This hit would be at 8.5 meters per second, an energy of 185 joules. That’s higher and harder than any existing helmet standard impact. We did one hit on the pavement and one hit on the curb anvil. We did them on the back of the helmets, in the center, because that was the only place we hadn’t hit them before. So, this last test is not directly comparable to the others. But it showed, in no uncertain terms, just how tough - and how protective - an inexpensive helmet can be. The peak Gs for the monster hits were 208 G for the curb impact and 209 G for the flat pavement impact. Just a few Gs more, that is, than many of the Snell-rated helmets transmitted in their seven-foot hits on the flat anvil. And even after those mega hits, the EPS liners were still nowhere near used up. The ZRP-1s are also well finished, quiet and very comfortable, though maybe a little short on venting. They’re also light: Our ZRP-1s weighed only about an ounce more than the lightest helmets in the test, the Arai Tracker GTs. What’s the cost for all this excellent impact absorption, comfort, light weight and highly durable finish? In a solid colour, a ZRP-1 retails for $79.95. The least-expensive helmets in the test, the $69.95 Pep Boys Raiders, also did well in all the standard impacts.
People, this huge brick was overkill but a stronger shell is going 2 take the initial impact better then a weak one will. The plastic seemed more like u just wearing a styrofoam helmet without a shell. This video is also a good feminder to ride safe, going 90mph head first into something and your helmet aint gonna do crap. But bounce it off the ground and the fiberglass gets my vote.
It collapsed and squished down until the face opening was not visible. Fiberglass in naturally flexible. It is springy. Your head would have been crushed like a Halloween pumpkin under someone's foot, while the helmet returned to its former glory. The best helmet does not dent or collapse.
Fiberglass is sturdier, lighter, disperses impact better. However i dont have many options( i have a weird head and live in a country where you eather by a shoei /arai /shark ) or you buy those sub 200 dollar helmet (barely any supplyers). Im 186 cm but have a size small head. I tryed an arai and my nose touches the chinbar, shark and suomy had too much up and down shake , agv gave me instant all round headacke, pressure on all the wrong points and still shaked up n down too much, unik policarbonate c01 fit the best, and didnt hurt but had plenty of preassure, rather have a well fitting helmet then a loosely fitting one . No im not shopping online the returns would be too much , no online domestic supplyers . Also your skull still has rigidity . Try and find a video of a chinese man with a shtty openface getting his head run over by a truck video( he survived ) but the helmet looked completely deformed. His helmet proveded enough resistance so his head wasnt crushed.
What is the test about? I doesn't show how much it bends when it hits your head. Carbon fiber is more flexi. But your skull will be broken and you would be dead anyway, just helmet would stay usable ... Nice one :o)
First of all.. Technically polycarbonate is supposed to be 4 times stronger than fiberglass when comes to impact.. Two criteria i am in doubt 1. Is LS2 helmet a true polycarbonate helmet or a fake ebay ls2? Shoei also have fakes.. 2. Assuming both helmets are original.. The years on the helmet (lifespan) plays a part on impact testing. Actual impact testing, original vs orignal, new vs new, impact testing must be in a controlled manner only can really tell the actual results. So to begin with.. I highly doubt both helmet wether is it orignal or fake
Sorry to say but this video is not a valid test and it's just destroying the a decent helmet for 54k views.... (Shoei was already broken anyway ;)) If someone's head was inside that Shoei at the moment of impact the skull would be broken and the brain likely partially smashed, after that the shell would return to its original shape. You can't judge by just looking just at the shell. Second, the angle of impact, are you sure they were identical or close to? In my opinion the greatest advantage of composite shells is way better shock absorption so that when one's head hits the ground it's not bounced straight away (just like shock absorbers in vehicle suspension).
I am very much in doubt that having an blunt object like that hitting you with that weight and speed would be survivable. So, as result the rider would be just as much dead in either of those helmets. And therefore I think this "test" is really not so much doing any real justice. I think that the real question here is this: Does a cheaper polycarbonate provide enough protection to save your day in an accident that is survivable when wearing more expensive a fiber/resin helmet?
Like everything else in this world... Wanna really protect you brain ? Then it's gonna cost you $1700 ... Wanna kinda protect your brain and have the cops leave you alone ? Then $189.99
What a bullship test. The brick hit the polycarbonate helmet with a sharp corner full on while the fiberglass helmet was only hit with a glancing blow with the brick sliding off the side of the helmet. The damage also shows this difference.
On a high level, polycarbonate is more expensive, flexible, softer, and lighter. Conversely, ABS is much cheaper, as well as harder, heavier, and more brittle. So if you want a helmet that's thin and light, you're much more likely to find that in a polycarbonate shell. so...... polycarbonate is better. hard and heavy doesn't translate to good...
@@usynnstradler Are polycarbonate and thermoplastic same ? In Google I couldn't find the the difference . It says polycarbonate is also a thermoplastic. And even abs is also a thermoplastic. Could you please explain if you have information ?
They know nothing abut subject of test, test also should be posted in slow motion, as fiberglass went back to its original position, but would your skull also?? Stupid test from stupid tester!
guys ive shared the image of the exact moment the cinder block lands on the fiberglass helmet and completely squashes it to 1/5 of its original volume. you'd still be dead. if you'd like to see it its here imgur.com/k0SqHnf
So you take a no name brand polycarbonate helmet I've never even heard of and put it up against a very high end fiberglass helmet. why don't you redo the experiment using an HJC CS-MX2 Creed with an advanced polycarbonate composite shell and see how that works out.
that's why Goalies helmets in hockey are made of fiberglass. with the right interior padding such as d30 your head would practically be invulnerable to blunt force trauma.
Haha, i know what you mean but it doesnt exactly work like that. Once the blunt trauma is protected against, the enemy is the speed of the blunt force which causes your brain to hit your skull. So yes the padding is where its at once the shell is strong enough. If we had like 16 layers of padding and the helmet was the size of a beach ball we might be approaching levels of almost invulnerable but then the leverage would snap your neck. But again fibreglass is way superior
@@absolutelysobeast you don't seem to be familiar with d30 and what it does it absorbs kenetic energy and displaces it so what your talking about is practically eliminated as far as cranial damage is concerned. I'm not talking about being hit by a Mac truck here. Normal motorcycle helmets save people all the time when they're in an accident so no you don't need a beach ball sized helmet. The material I am referring to is being implemented in professional football helmets as well as military applications and it is currently commercially available.
The comparison is so wrong that it is the first time I have seen your videos and I was already disappointed. I agree that the material of the 2 is plastic, but what you are not taking into account is the number of layers they have in their preparation and that they are manufactured for 2 different types of user, point number one. Point number 2, the user to whom it is addressed has to do with point number one since the LS2 is aimed at a user of the delivery type or short trips at low speed and the SHOEI is aimed at a user of a high speed motorcycle displacement that travels from medium to high speed, So there will be a difference in the resistance of both.
Great Video. I was wearing a Shoei Fib/Carbon full face when a lady in her infinite wisdom, turned into my path at a set of traffic lights. I was going around 35mph when I hit the drivers side front of her car ( from my viewpoint it was my left as I hit her - New Zealand - drive on the left ) and I flew over the bonnet ( hood ) and missed the windscreen; sailed past and landed onto the top right of my Shoei, basically went straight into the road headfirst... Here’s the interesting thing - in that split second when everything seems to slow down, I felt the helmet “compress” and then “ripples” move around the inside? ( not sure ) of the helmet - almost like ripples in a bath tub if you drop the soap. My head also “appeared” to bounce - much like I watched the concrete block do on the Shoei in this vid. I will never forget the sensation - truly interesting to feel. Long story short - Afterwards I was checking the helmet and noticed, that for a head first landing on the road, there was very little noticeable damage at the impact site; however, at the rear of the helmet ( away from impact ) and at about 5 o’clock on the helmet - It was obviously distressed. Flaking fiberglass and spider-webs. My take away from this was - those “ripples” I felt must have been the energy moving from impact point, to the rear - and out. It’s the only thing that makes sense. Hope this helps someone. Cheers.
Sorry about the crash man. As far as i understand it, thats why fibre glass is better. It spiders and almost shatters like tempered glass which spreads the energy out over a broader area. I have the option of a fibreglass hjc that i know fits vs a bell polycarb with MIPS. Tough choice man but fibreglass seems like a better bet for me
I watch Demolition Ranch on youtube and he has a video where he shoots a glass ball. This same type of thing happens where the energy travels around from where it’s shot and cracks the back. I’m guessing it’s a similar phenomenon, but I’m not sure what’s happening. Glad to hear you’re doing well after something like that!
This video aside, fiberglass is better than polycarbonate. It distributes the force across a wider area than cheap, bargain basement polycarbonate. But it's your head, buy what you want. :D
ls2 are garbage helmets. quality is absolute garbage. stay away. I had 1 and never again. its junk. invest in a better helmet. maybe scorpion or shark or even nolan.xlite. tons of others besides that ls2 garbage.
How high did you drop the block from? What is the weight of the cinder block?
Did you see the flex on the fiberglass helmet? Your skull would have been crushed just as much the poly shell. The only difference is the permanent deformation.

This "scientific" test only proves what physics already tells us. I would not be afraid to wear either helmet. If you get hit in the head by a 30-35lb block from 20ft your going to die.
@R3Vlog And that was exactly the point of the demonstration
You should have placed a water melon to assess the damage
You needed a melon to know that LS2 would kill you 😅😅😅😅
The orientation of the block on impact plays a roll here. Would love to see the same experiment with bowling balls or something. Not the the results would nessisarily be that different, it would just remove one more extraneous variable.

I was looking for abs vs polycarbonate now fucking again new concept polycarbonate vs fiberglass😢🤬
Like everything else in this world... Wanna really protect you brain ? Then it's gonna cost you $1700 ... Wanna kinda protect your brain and have the cops leave you alone ? Then $189.99
What a bullship test. The brick hit the polycarbonate helmet with a sharp corner full on while the fiberglass helmet was only hit with a glancing blow with the brick sliding off the side of the helmet. The damage also shows this difference.
Is ABS same as Polycarbonate ?
On a high level, polycarbonate is more expensive, flexible, softer, and lighter. Conversely, ABS is much cheaper, as well as harder, heavier, and more brittle. So if you want a helmet that's thin and light, you're much more likely to find that in a polycarbonate shell.
so...... polycarbonate is better. hard and heavy doesn't translate to good...
@@usynnstradler Are polycarbonate and thermoplastic same ? In Google I couldn't find the the difference . It says polycarbonate is also a thermoplastic. And even abs is also a thermoplastic. Could you please explain if you have information ?
@@JC-nx5xx"thermo" means heat.
So, both abs and polycarbonate are melted at high temperatures and put into moulds to create a helmet shell.
Kevlar helmet next please sir
Which grade of fiberglass is better to mould a helmet??? Plzzz reply
They know nothing abut subject of test, test also should be posted in slow motion, as fiberglass went back to its original position, but would your skull also?? Stupid test from stupid tester!
The sound is not so good, plus adding music to it makes it worse.
guys ive shared the image of the exact moment the cinder block lands on the fiberglass helmet and completely squashes it to 1/5 of its original volume. you'd still be dead. if you'd like to see it its here imgur.com/k0SqHnf
So you take a no name brand polycarbonate helmet I've never even heard of and put it up against a very high end fiberglass helmet. why don't you redo the experiment using an HJC CS-MX2 Creed with an advanced polycarbonate composite shell and see how that works out.
Even if the helmet survive that impact, your neck won't !
So say hello to permanently damaged from neck and down
both wearers die look at the indention
What is the distance from the falling brick to helmer
About 20 ft.
It's not about helmet damage, but energy transfer to the brain. Not a legit test.
that's why Goalies helmets in hockey are made of fiberglass. with the right interior padding such as d30 your head would practically be invulnerable to blunt force trauma.
Haha, i know what you mean but it doesnt exactly work like that. Once the blunt trauma is protected against, the enemy is the speed of the blunt force which causes your brain to hit your skull. So yes the padding is where its at once the shell is strong enough. If we had like 16 layers of padding and the helmet was the size of a beach ball we might be approaching levels of almost invulnerable but then the leverage would snap your neck. But again fibreglass is way superior
@@absolutelysobeast you don't seem to be familiar with d30 and what it does it absorbs kenetic energy and displaces it so what your talking about is practically eliminated as far as cranial damage is concerned. I'm not talking about being hit by a Mac truck here. Normal motorcycle helmets save people all the time when they're in an accident so no you don't need a beach ball sized helmet. The material I am referring to is being implemented in professional football helmets as well as military applications and it is currently commercially available.
These are shocking results
01:45
The comparison is so wrong that it is the first time I have seen your videos and I was already disappointed. I agree that the material of the 2 is plastic, but what you are not taking into account is the number of layers they have in their preparation and that they are manufactured for 2 different types of user, point number one. Point number 2, the user to whom it is addressed has to do with point number one since the LS2 is aimed at a user of the delivery type or short trips at low speed and the SHOEI is aimed at a user of a high speed motorcycle displacement that travels from medium to high speed, So there will be a difference in the resistance of both.
Rubber duck is the best then 🤣
Great Video. I was wearing a Shoei Fib/Carbon full face when a lady in her infinite wisdom, turned into my path at a set of traffic lights. I was going around 35mph when I hit the drivers side front of her car ( from my viewpoint it was my left as I hit her - New Zealand - drive on the left ) and I flew over the bonnet ( hood ) and missed the windscreen; sailed past and landed onto the top right of my Shoei, basically went straight into the road headfirst...
Here’s the interesting thing - in that split second when everything seems to slow down, I felt the helmet “compress” and then “ripples” move around the inside? ( not sure ) of the helmet - almost like ripples in a bath tub if you drop the soap. My head also “appeared” to bounce - much like I watched the concrete block do on the Shoei in this vid. I will never forget the sensation - truly interesting to feel.
Long story short - Afterwards I was checking the helmet and noticed, that for a head first landing on the road, there was very little noticeable damage at the impact site; however, at the rear of the helmet ( away from impact ) and at about 5 o’clock on the helmet - It was obviously distressed. Flaking fiberglass and spider-webs.
My take away from this was - those “ripples” I felt must have been the energy moving from impact point, to the rear - and out. It’s the only thing that makes sense.
Hope this helps someone.
Cheers.
Interesting observations I hope never to experience myself.
Sorry about the crash man. As far as i understand it, thats why fibre glass is better. It spiders and almost shatters like tempered glass which spreads the energy out over a broader area. I have the option of a fibreglass hjc that i know fits vs a bell polycarb with MIPS. Tough choice man but fibreglass seems like a better bet for me
Did you sustain a concussion?
I watch Demolition Ranch on youtube and he has a video where he shoots a glass ball. This same type of thing happens where the energy travels around from where it’s shot and cracks the back. I’m guessing it’s a similar phenomenon, but I’m not sure what’s happening. Glad to hear you’re doing well after something like that!
test kan ikke bruges til noget
This video aside, fiberglass is better than polycarbonate. It distributes the force across a wider area than cheap, bargain basement polycarbonate.
But it's your head, buy what you want. :D
LS2 vs SHOEI....Mercedes vs Fiat...not a fair comparison.
He should take two helmets from the same company. Test is useless.
You can send us two helmets from your favorite company and we will gladly perform our highly scientific test agan.
shoei is the mercedes not the ls2
You know what better than any helmet? A car.
Very interesting. Thanks for that. It was disturbing watching the flex of the polycarbonate helmet. Wow. Subscribed.
Csodálatos ez a "Fiberglass", de a fejed nem ilyen rugalmas! ;)
Lassitsd ki a becsapódást, meglepődsz, az áll beleüt a homlokba!
Nothing except a large piece of rubber could save you from such an impact. Complete garbage test, show you nothing.
ls2 vs shoei;really;how stupid you think we are;
Could you guys save me with those cool helmets rather than crash testing🤕
Test with watermelon
This guy is a goof....
🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
fkg irritating music ...you're not a DJ
The best helmets have an engine and 4 wheels and you can fit the rest of your body inside.
Also, the best helmet is people paying attention while driving their cars and/or not being a Fast & Furious wannabe.
Sounds like a hearse to me
People still die from head trauma inside cars. Professional drivers also wear helmets.
🤣🤣👌
ls2 are garbage helmets. quality is absolute garbage. stay away. I had 1 and never again. its junk. invest in a better helmet. maybe scorpion or shark or even nolan.xlite. tons of others besides that ls2 garbage.
Wow. Fiberglass is way better than polycarbonate
No it's not this was a bs review
No, the fiberglass was just more flexible 1:45, but your skull isn't that flexible.
@@NoName-cx3gk i agree!
