From the actual website
When tested against the British Standards (EN 1078) at the Imperial College, Kranium absorbs 4 times the amount of impact energy when compared to regular cycling helmets.

It doesn't state anywhere that it offers more protection than a motorcycle helmet.
Just that it's better than your typical walmart bicycle helmet.

It's stupid to buy expensive motorcycle helmets, they are more delicate than normal ones, you drop one on the floor and you have to buy another one, how smart is that?

I don't understand how this is related to motorcycle helmets.

But if you do toss your Arai or Shoei, let me know where. I could use a spare.

It's stupid to drop one on the floor, very smart to buy a good quality helmet.

I personally buy the best I can afford, a few hundred bucks or my head...easy choice.

Not me, half the people in this website claim that if your helmet rolls off your kitchen table you have to buy another $600 helmet, even though the helmet or the visor are not cracked. I also want to know where they discard their expensive dropped helmets to collect a few.

I've never seen the inside of a helmet, nor do I know -or care- what it's made of.
But there's a lot more knowledgeable people than me out there, and if they say the foamy thingy inside my helmet will take a hit even with a small fall, hell, I believe them (again, how much is your head worth to you?).

I've never dropped a helmet and, quite frankly, I don't know if I'd replace it right away given that scenario.

Actually, you're supposed to replace ANY helmet that's dropped. Since you don't know if it's compromised or not...and you'd potentially find out in a manner you don't want to I suppose.

Are you trying to make me believe that the guy in the pic received that face damage because when he crashed he was using a helmet that dropped off the seat of his bike? Please. And are you telling me that he would have not received that damage if he had been wearing an identical but never-dropped helmet? Yeah okay.

The amount of exaggeration and drama-queenism in this forum makes me nauseated, don't get me wrong I also love to protect myself and ride safely but I don't believe a helmet is rendered worthless because it rolled off your bike seat and hit the ground, I also do not believe that you have to gear up with heavy armor and ride all sweaty and bulky. The reason why I ride motorcycle is the freedom of it, I ride in my t-shirt and let the breeze hit all my body, if I want to be protected I'll just drive my car. I also don't intend to ride like an idiot and recklessly, thus the reason why I don't put on leather armor all over.

K I crashed at ~130km/h in my Joe Rocket helmet.

I crashed again at ~40km/h stunting with that helmet.

Both times my head smashed the ground. Both times I felt nothing nor did I suffer any damage to the head.

I still wear it (occasionally). I trust it more than anything. GO JOE!

Don't care what anyone says I'm never letting it go.

Hello? Where did I say any of that? Um...yeah. Didn't. Try not reading anything and everything into my post. My point is, once a helmet is compromised (and it may be once dropped without you realising it)...it may not protect your head in the manner it's supposed to...and guess what? You won't know until you NEED IT. Then after it fails and breaks apart or something stupid...you'll perhaps have the opportunity (if you're lucky and your head doesn't break apart with it) to look back and think "Ohhhh....". My point with the photo is that if your helmet is compromised and you don't know it....you could end up injured because of it. Is it worth it?

Show us your research numbers.

Facts please again.

I've NEVER dropped a helmet and I handle it like it's worth $1000. So buy your cheap helmet and throw it around but don't think that a cheap helmet is more durable than an expensive one.

I don't know much about how well dropped or not dropped motorcycle helmets protect you because I've never had a spill where my helmet took damage.

What I do know, first hand experience is with snowboard helmets. I wear a snowboard helmet two seasons before I replace it, I snowboard about 20 times a season and have 3 or 4 really bad wipe outs. These wipe outs are at around 60km/h, going as fast as I possibly can, somersault in the air, land on my head HARD on patches of ice and slide down the slope as I come back from blacking out.

What hurts the most is probably my butt or shoulder.. but my head? Never a scratch or headache or bruise. These snowboard helmets are about $100 and take a beating over and over and over again. They are made of foam on the inside, much like your bicycle helmet.

If an Arai $700 helmet has so much more tech than your typical Red snowboard helmet and they take A LOT of abuse, then I'm sure dropping an Arai off the kitchen table will weaken it but it will still protect you. I strongly believe the whole if it drops, replace it, is due to liability concerns. Everyone says that if you take one fall in a snowboard helmet, you should replace it but they keep on protecting my noggin' and that's first hand experience.

The whole point of a helmet is to absorb the energy from an impact, lessening the chances of a head injury. The inner lining of a helmet is constructed from a special foam that'll crush in the event of an impact in order to increase the stopping distance your head has to travel before coming to a dead stop; in other words its "cushioning" your head in the event of impact. Once the foams been crushed, its done its job and will no longer offer this protection.

The outer shell acts to spread the energy from the impact over a greater area, thus decreasing the impact energy absorbed at every instantenous point around the impact area; instead of concentrating it all at a smaller point which will do greater harm. Once an impact has occured, it WILL leave cracks on the surface where the impact took place. These could be microcracks, which you wouldn't be able to see.

With that all said, suppose after falling, you decide to use that already compromised helmet again. As stated above the outer surface acts to spread the area of the impact, and the inner lining will crush around this area to cushion your head; it could be a pretty big area. If there's any engineers reading this, you'll also know how serious cracks and crack propagation can be, and how easily it can lead to the compromising the strength and integrity of any material. During your next fall, not only will you not have the ability to cushion your fall, there's a pretty good chance the outter shell can break wide open, leaving you pretty vulnerable to whatever you're about to collide with.

Aparently the little drop is not enough to damage the helmet. Jay Leno on his garage site has a vid up with a rep from Arai that says so. Seen it on here but not sure where to find it.

Yes a dropped or even crashed in helmet is still a million times better than no helmet at all.
