What a lame "test"

the first helmet was struck by the corner of the block. the second one wasn't. for this and many reasons this was nowhere near a scientific test. real tests are CONTROLLED. The DOT, ECE, Snell tests are no secret. You could replicate them if you wanted. But you're not. You're just making more bullshit for youtube.

FIRST RIDER BLATED THE HEAD AND THE SECOND RIDER BROKE HIS NECK..

THE DIFFERENCE WAS FIRST HEAD WAS DID BLOW OUT AND THE SECOND HEAD DID BLOW OUT NECK

What size did this person had on?

Alpinestars test team: Start talking!! *detonates vest*

Just interested if the tech 5 is underneath or is this a jacket on the market?

What triggers the vest to inflate?

Music is too loud :(

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)

Have you seen the reviews of the Tech-Air5 app in the Play Store? Is the vest at the same level?

It's 'Yamaha Champions Riding School' (YCRS)

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.

Does it protect the neck?

So that’s how you pronounce Arai

I have mine and this video helped with a lot of info. Will be looking for operation vids.

Good questions. Thanks for putting this together.

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

This guy is a goof....

4 hours to 100% charge time: maybe when brand new. Before long it takes twice that. I've had my current phone about 6 years but it still recharges really fast. Why can't they put a decent battery in these things?

es reutilizable?

Hi justin bieber

Lol. “Layman’s terms”

I was looking for abs vs polycarbonate now fucking again new concept polycarbonate vs fiberglass😢🤬

Model of this jacket?

The beginning of this video sounds like 'snell' is a scammy, detached college student's thesis project Hopefully, they obeyed the laws of physics ...wow

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

Twice it had saved my life and now I own the tech 10 system. I wear it on the street. The first time I got hit by a drunk driver at 60mph. Witness said it was like watching a ball bounce down the street. Saved my life. Second time wasn’t as bad but could have been without the vest. Lightweight, comfortable, and it saves your life. No brainer.

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.

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).

All this shit and never asked how many shell sizes they use 😵‍💫

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!

The sound is not so good, plus adding music to it makes it worse.

Cool

🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

ls2 vs shoei;really;how stupid you think we are;

It's not about helmet damage, but energy transfer to the brain. Not a legit test.

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?

Why fiberglas is not slowmotion

whatever you guys wear. Just ride safely!..

You know what better than any helmet? A car.

How do I know which size is right for me? I have an alpinestars missile v2 professional size 52. I tried the airbag and the size S is really tight and hurts a little in the armpits. Should it be like this or is size M better where there is some slack?

fkg irritating music ...you're not a DJ

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.

this hardly replicates crash, because both helmets are squashed out of shape when you watch slo-mo, i dunno about you, but my head bones are not elastic, if someting squashed the helmet like that, you'll be dead, even with an 'intact' helmet...(just play the video on 0.25 speed and pause it at 1:45 the helmet is squashed almost to the floor) of course in real crash your head bounces somewhat, so for sure fiberglass is better option, but both of those impacts are pretty scary

Even if the helmet survive that impact, your neck won't ! So say hello to permanently damaged from neck and down

The most unscientific test. Idiotic nonsense like this shouldn't be posted on YT. Fiberglass might as well be better but this is nowhere close to be qualified as a comparison.

Just researching the techair 5. Guessing yours was the older version. You had broken your neck in 3 places from the 1st crash....how the heck were you able or even allowed to race 6 weeks later to crash again and did that have a compounded effect on the breaks? Have you tried any of the airbag pants?
