Having worked in Destructive and non-destructive testing for years I understand and was aware of this method. Great to see the information presented in a basic and understandable form for the layman 👍
Great video but would still love to see at what point they would deem a helmet unsafe and at that point prove it off against a new helmet of the same make in say an impact test. I really don't see how a modern Carbon fibre Helmet that weighs next to nothing can be wrote off by a 1mtr tumble (Empty) when they are designed to protect your Mellon at speed when the forces would be insane. Most Manufacturers must take something like this into account as people would never buy another high end Helmet again if you're paying £400 a time for a light drop? # I would be very interested to hear a manufactures point of view on this topic.
I am not a helmet manufacturer, but I work with one in a different end use sector. Manufacturers cannot provide blanket advice on continued use that would cover every instance of a helmet being dropped. There could foreseeably be circumstances in which that advice would no longer be valid and the owner would continue to wear their helmet, believing it to be safe, when the particular circumstances of how it fell and impacted the ground had rendered it otherwise. Consequently, advising consumers to replace any helmet that has been dropped becomes the default position from a product liability perspective. The service the Helmet Inspection Company is offering looks like it takes out the uncertainty.
A pristine helmet will dissipate impact forces uniformly, thus saving your head. A damaged helmet with even microscopic cracks will distribute the impact force along those crack lines, thus focusing the force on one region instead of dissipating uniformly. So, manufacturers' cannot provide any advice on continued use as they cannot predict what kind of force will create such a loss of integrity. So, usually, they can assure safety only in one crash, big or small - even a 1m drop. You need to get it examined or trash it if cracks are visible.
Exellent post, I could have listened to the professor for the hour, fascinating stuff. The big bike shops should be offering a service like this, if they don't they are fools.
For anyone questing this it's simple. All materials expand and contract with heat everything from your front door to a bridge all he is looking for using lasers is uniform movement any irregular movement is a sign of either damage or a secondary material
Great idea and the science is good. Only question is - when they see defects, how do they/we know when it is serious enough to say helmet isn't fit for purpose anymore?
@@helmetinspection Really interesting stuff. So is a small drop likely to scrap a lid? I've thrown quite a few over the years after minor drops and now I'm wondering if that was completely necessary. Lets presume a decent quality one - I usually use Shoei - is a fall from a handlebar likely to be a big problem or is it more serious stuff? I've thrown ones which have had a good impact (crashing) and ones which have slipped from my hand at about an 18 inch drop. For £40 I would imagine you guys could have saved me quite a bit over the years.
@@siraff4461 In short, a visual inspection on a helmet is a bit like trying to predict winning lottery numbers. The outer side of a helmet is pretty good at holding onto its secrets.
I agree with what's been said, also we can't do a destructive test just to prove the strength of the helmet. When damage has been verified how do they then make a judgement, do they work on a percentage...? 10%, 25%,75 % of its structural integrity been compromised.
Same with carbon fiber . Looks good on the surface but can be damaged underneath or between the layers . Usually you can find defects by tapping the area and then the surrounding area and if the tone changes you know there's damage .
Hey chops thanks for highlighting this service it certainly provides peace of mind, my only concern is sending a lid via a courier they aren’t known for their gentleness - a bit like your travelling on a plane scenario. Never the less the actual testing is really worthwhile and useful, cheers Mr C 👍
Hi Andrew. If you pick up an oversized double-lined cardboard box off Amazon and make sure the void space (top, bottom & all sides) is filled with something like loosely scrunched up newspaper pages, you'll have nothing to worry about. Most courier drivers are self-employed these days, so it's not in their interest to have a black mark against their name. We also ask that you upload a couple of images of your helmet before you box it up. After you've booked an inspection on our website, we automatically insure your lid to the value of £5k for both outward and return legs of the journey. All the best. Martin
What a great service, thanks for sharing Chopsy! Also demonstrates how great we are as a country at developing smart solutions to real world problems. Just bookmarked the link for future reference. Cheers!
Thanks for putting this fascinating video out Chopsy. Must be the most useful biking vid in years. £40 is just the right price point to get your precious lid checked out. I'm definitely going to make a note of the details for future use. 👍
I liked this and while it sounds all good ( and I know you gave your warning about snake oil/ Baffling with Bull-S~~t) Id really like to see you test some helmets from "new". Maybe a cheapo £40-60 one and a mid-range one and if you can find the backing for this a higher end one? Id love to see what the tests says before and after "dropping " them. I appreciate this is probably pie in the sky idea but this would have been a more thorough test (Although admittedly not exhaustive). Maybe a idea for collaboration with these guys again?
@landyman33 I like the way you're thinking ... We're in early-stage conversations with a UK motorcycle helmet manufacturer to do just this. It's rare (and very refreshing) to see a manufacturer want this level of transparency about their product. Sadly though, our approaches to the importers of the larger helmet manufacturers have fallen on deaf ears. Speaking as a business owner, that's their prerogative. However, speaking as a biker who owns a number of their products, I'm keen to understand why they're not interested in a conversation that could potentially lead to a better product and greater levels of customer safety. These are the same manufacturers who beat the drum that safety is their first and foremost concern, yet their lack of curiosity about our service seems to suggest otherwise. Cheers, Martin
Absolutely fascinating Chops, thank you. I was expecting you to announce at the end that the testing was prohibitively expensive to those with anything other than top end helmets, but absolutely not, and if in doubt you'd have to be mad not to use this incredible service. I just hope they don't get deluged and have to put the price up!
Excellent job and very informative , but, it now raises more questions, helmets are manufactured and distributed all over the world and all over our country being delivered to customers then returned to the shop and sold again, shipped again, vicious circle of handling and mis handling, although as your video showed that defect cannot be detected visually so what do we do as customers, buy the helmet that you would like to keep and wear then to satisfy your self that your helmet is safe to use have it tested, now faults are found caused either during manufacture or mishandling along the line to you, what happens then, return for inspection(probably only visual) no fault found and returned back to you, or send it back with the report from the tester, bit of a vicious circle? Apologies for my ramblings but it does beg the question, how do we buy a helmet that has not travelled many miles and handled by many people to end up on ones head and know that it is defect free, million dollar question? Cheers and ride safe.
Great information, mind boggling for sure. For £40 it’s well worth checking if you have dropped your lid, especially with the cost of most of them these days. 🙄👍🏻👍🏻
Thank you very much for the test based on facts ( I am btw an auditor for composite material in the aircraft industry, it means I have a little inside of the material and that was very interesting) ...I am just considering to buy a new Shoei because I dropped my AGV last year...4 years old...decision is clear...a new one is ordered....thank you again and many greetings from Hamburg Germany
What a great idea and at £40 it's very affordable... I've dropped my helmet once, it landed on the open visor which snapped the hinge so I assumed that absorbed the shock so still use it. Only £40 to get it checked out is very affordable!!
Wow , that was really interesting , I dropped my helmet and bought a new one just to put my mind at rest , but this is a service where you can have it tested and have it checked and to know the outcome of the helmet once and for all . Thanks for doing this video John 👍
That's pretty much the circumstances I went through which led to starting up the business. My dropped helmet was saved from the skip because of what we're now doing.
Great informative vid chopsy had no idea this service was available. Also the only problem I can see is would you trust a bloody courier service not to damage it on route lol. 😂😂
We hear this one quite a bit about couriers. The answer lies in the packaging. Get an over-sized double-walled cardboard box for a couple of quid off Amazon and make sure you fill the void space with something like the pages from a newspaper (MCN?). Most of the couriers are self-employed, so it's not in their interest to have a black mark against their name. Cheers, Martin.

Timely video chops. I put my new Arai on the bike seat while I was open my garage door and it the floor. Only a small chip in the side . I just brought another one costly mistake. Proper interesting stuff.
This is one of the most interesting videos I can recall that I've ever seen. The funny part is it's kind of way above my head but the way this guy explains it makes sense to me.
I was on the sidelines when Chopsy and the Professor were going through the testing procedure. It was great seeing his reaction to what we were showing him. Cheers, Martin
Chops has learned me summat…wonders will never cease! Really good article this, very interesting and something that will affect most of us at some point, we’ve all done it and all thought the same thing. Well done fella!
A fascinating video. I heard from an ambulance crew recently that it is important that when a helmet is removed from a biker it is taken with the patient to hospital so that the surgeon can choose whether to have the shell scanned give more information about the location and severity of a head injury. It would be interesting to see whether a hospital scanner might be similarly used for testing and how that data compares to the laser/heat expansion approach on strain testing. Could AI remove the need for human interpretation?
I had my Aria Rx7 skittled 10ft across the concrete in Santander ferry port after taking it off in 30c heat , placing it on the floor next to the bike , and some idiot came running through the line of bikes and chose between mine and my wife’s bike to cut through , clattering my helmet and snapping off the visor and GoPro 🤬🤬🤬 Good interesting video chops, will bear that service in mind if I’m ever unlucky again mate 👍🏼
Hey Peter. I watched that video several times. It had a senior USA rep. from the manufacturer stating that if your head wasn't in it when it was dropped, it'll be perfectly safe to continue to use. In fact, I reference this same video here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uprBkhsKXJQ.html It's possibly one of the most irresponsible statements I've ever heard regarding biker safety. All the best, Martin
This is the first time I've ever seen an actual scientific test that makes sense and demonstrates just how easy it is to damage one of these buckets! One thing you might want to consider is when the author of the video had the engineer explain the damage to the interior of the shell of the bucket even though very little if any damage could be seen from visually examining the object. Notice the part where he explains how the outer shell of the bucket flexes inwardly upon impact. Some engineers from Australia in cooperation with some brain surgeons found that when a helmet being warn impacts a hard surface like the roadway in a fall off a bike, the helmet flexes inwardly transitioning the force of impact in toward the head which continues to move toward the flexing surface and receives the force of the flexing impact and then when the head continues to move toward the impact zone, the head is again impacted causing another impact force to impact the head causing a "double-impact effect" which would not have occurred if the head had not been enclosed within the bucket! So, wearing a bucket on your head actually causes more damage than if the head had made contact with the hard surface without the bucket being worn. Another problem with wearing these full-face buckets is that when in an accident the rider's body moves forward and his head makes contact with a hard surface the head will be forced to the rear as his body continues to move forward. Now, consider that the rider's bucket is held in plce by a strap that is tightened below his chin on his neck. Now, consider the helmet moving backwards, the body moving forward and as the bucket moves to the rear, the back of the bucket comes in contact with the shoulders and the upper back. This causes the force to be applied to the strap under the chin to tighten around the neck until the neck snaps the same as it would if the situation had been using a "hangman's noose" around the rider's neck, the rider drops and when the rope tightens to it's limit, the knott of the noose snaps the person's neck! Now consider the fact that the rider has to support his head upon his neck which amounts to a weight of approximately 11 lbs resting upon 7 small cervical vertebrae supported by several small neck muscles. Now, add another three pounds to the eleven and you have approximately 14 lbs of pressure forcing it's way down upon these vertebrae and musckes. Now, consider the force upon the helmet caused by air friction when the rider is traveling at 70mph! The strain upon the cervical vertebrae and those small muscles is extreme! So much so that it causes extreme fatigue of those muscles which causes the rider to become not only fatigued, but also less aware of his surroundings and less aware of the traffic around him! This can cause accidents and even death! Now consider this in addition to the "double-impact effect" and the neck is snapped even more easily in an accident. There are many reasons why wearing a bucket, even a very expensive on, is extremely dangerous and seldom thought of by the rider because he is unaware of the physical effects caused by wearing a bucket on his head! Neither the government nor the manufacturers of buckets will admit these facts to riders!
Very interesting. It would be fantastic if he had a baseline quality spec for the big manufacturers to compare so you could at least say the structural integrity is the same, better, or worse than the spec limit of the manufacturer.
I started out thinking about baselines and assumed this would be impossible to do if we couldn't have baseline data from manufacturers. But the fact is we don't need a baseline. With the exception of manufacturing weak points, which are present around apertures, fixings and air ducts ... damage is damage. It's binary. That's why we only provide a pass or a fail. There's no ambiguity.
@@helmetinspection that makes sense. However, my thought to your binary point was how much damage is normal from the factory as each manufacturer has their own tolerance for acceptable quality. Since Snell, ece, and DOT do not inspect each production unit but instead a sampling pre-production. It makes me wonder if safety ratings are really just relative (I think we know they are) or are they rubbish?
@@chadgruver4423 Another good question ... The manufacturers and the destructive test authorities cannot currently determine what these tolerances should be because they don’t have the data that our non-destructive test provides. There's a willingness on our part to work with all of the manufacturers, and we have made attempts to contact many of them via their UK distributors - but with no success. I'm not sure why we haven't had any success in getting these conversations started. That said, one motorcycle helmet manufacturer has contacted us. A British company that has taken the time to speak with us to understand what it is we bring to the table. However, they've not taken us at face value. Their engineering division set us stringent technical challenges, which we delivered on. Martin
When they analyse the crash helmet do they give you any images or data regarding damage? Would be great to send one to them I have crashed in and see how it held up! Another great video chops
I had my carbon bell helmet on my mirror stork while in the garage getting fuel and the wind blew it off onto the floor. It chipped the clear coat. I was unsure to use it or not. So I took it to the TT in 2017 and had the riders sign it. It’s now a display item
I would actually say that if my helmet is going to be write off if it fells of the bike, then I will not buy that brand of helmet ever in my life :))..... If I want a tinfoil helmet I will make one myself, If not I would like it to keep me warm and safe in an impact at 60 mph at least :)).... I had an IXS helmet with which I hit the ground at 40 mph ( was oks) and the guys at IXS and the service looked at it and said that I could try that some more times, because the scratches were only to the paint :)) Sounds legit, measuring engineer specialist here :))....... Might as well be a lovely try to see if my IXS is still worthy after a hard fall and some branches over it in the dirt :)).... And how obliterated is it compared to it still looking decent enough :D.
It'd be really interesting to see some data sets from this. How many people are riding with structurally compromised helmets without knowing it? Are helmets generally fine after a drop or not? Does it vary between brands and materials?
Yes that's an idea, only issue I could see is any vibration really impacts the results as you can imagine they are measuring tiny tolerances. Even someone walking around the room interferes with the results
We've been considering doing shows and putting on events at a few of the retailers (Sports Bike Shop etc). We're also speaking with one of the helmet manufacturers about possibly doing something at the BSB events - secure helmet storage and a scanning service while customers watch the racing. Cheers, Martin
@@LambChopRides these are engineering challenges - the guys have overcome these challenges when they test lifeboats - JT's already working on a solution 👌
Thanks Chops. Interesting, but to what extent does the damage shown render the helmet useless for its intended purpose? Does any darkening mean it is fit for the bin, or is there a threshold? Also agree with another poster that the courier is more likely to kill the lid!
Good info I had no idea such a service or technology was available ! Well worth it if you have a £200+ helmet. Not really worth it for my NexxDX1 which has hit the deck more times than I care to remember, all green lane falls. It's due to be replaced soon coming up to 3 years old and has served me well. Thanks for sharing😀
Measuring heated expanded material does not tell you, in my point o view, if the material is compromised, it only tell's you that part is easy expandable by heat because of prior movement do to low G impact, it can still be more than strong engouht. Helmets are tested for high G impacts drops are drops.
Very informative and interesting. Just to say I’ve took my helmets abroad but never put them in the hold luggage. Always took my helmet on as hand luggage. As you said you just never know how your bag/case is thrown around.
Now knowing this service even exist is great and would do well with your advertising. Cheaper to test and poss bin the lid than just replacing +£400 helmet.
So they can see spots of weakness in dropped helmets but how are they the authority stating it's damaged beyond protecting you adequately. Conventional wisdom claims a dropped helmet is fine as it's a impact while being worn putting counter pressure on the inside really damages a helmet too much.
@@LambChopRides 100% ... if the structure of the helmet is compromised (cracks etc.) it's time for a new helmet. Our service is focused on exposing the damage you can't see, e.g. after a minor drop - or if the helmet is nearing the manufacturer's stated life span.
Interesting equipment they use with many applications. Certainly makes one wonder if its worth buying a 1000 dollar helmet if it can be damaged easily and you'd never know by looking at it. I'm encouraged to choose helmets wisely now and really get value for money. Also good to know we got machines to scan for damage. Thanks for original content Chopsie!
It's hard for me to keep thinking about helmets. I purchase one, maybe two helmets every 3 or 4 years. I believe that the human skull, with brains included, can at best survive a 28 mile an hour to zero deceleration. It's way, way, way better to have a high-speed get off and tear up most of your body then have a skull deceleration at more thanks 28 mph. What happens is coup- contracoup. The initial impact creates a frontal assault and your brain, with inertia, accelerates forward and brakes many important nerve connections. When it rebounds it will also break many frontal lobe connections. I mean break as in being disturbed or disconnected. If your brain is gone I suppose it's time to think about the afterlife if there is one. ( Of course your brain being gone........)
Chops depending on the difference in thickness materials will experience thermal expansion at different rates, this is true of most overlaying processes such as carbon Fibre and fiberglass. Thicker areas could possibly show as dark areas depending on the rate of expansion. Depending how you interpret the results the dark areas could actually be viewed as stronger 💪. Surely we should have witnessed a test of a couple of brand new helmets before and after impact. I know I sound sceptical boardering on negative "believe only half of what you see and none of what you hear and you won't go far wrong" what I'm trying to say I haven't discounted the process I'd just like to see tests conducted with a little more vigor! Cheers Chops still enjoyed the video 😁
Hi Chris You're quite right about issues to do with the material thickness, and if you notice in the video I highlight this by explaining the presence of cooling ducts in the helmet as a consequence of section changes. What we’re looking for are anomalies in the overall structural behaviour, so what you see on the output as a dark area is an anomaly due to damage. Thickness variations are shown up differently. Unfortunately, we didn't have time to go through the full analytical procedures that we undertake when inspecting a helmet and there is a lot of direct strain analysis that is undertaken within the equipment to give us the assistance in making decisions concerning damage compared to section change. Your comments concerning new helmets are well made. However, how do you know when you receive a new helmet that it is actually free from defects? Unfortunately the manufacturers don't have this capability so they rely on statistical sample testing. Say, for example, one in every thousand helmets are taken off-line and destructively tested using impact testers and sectioning the helmet with a saw. We have a lot of experience of looking at automatic, semi-automatic and hand layup of composite structures and there are inevitably defects introduced during manufacture, transportation, storage, sale and use. I have tested new helmets and seen variation in manufacture and should say I also test my own crash helmets. We have a lot of experience looking at all sorts of different effects families and creating those during manufacturing of test coupons or by testing finished components. Suffice to say it is this rigour that we use from all our other accredited testing procedures in automotive, maritime, aerospace that we apply equally to crash helmets. Have a look at the technology explainer's on the website helmetinspection.co.uk/the-science-of-crash-helmet-testing/ Regards, John
Really interesting video Chopsy well done mate! Other parts of biking just as relevant as the bikes. The main brands silence on this issue is telling…happy to charge crazy money for their products, not so keen on real world hi-tech testing it seems 😉
I’ve had two helmets delivered in last 18 months both where damage in transit by the carrier between Sportsbikeshop and my home in East Yorkshire! I went to a Honda dealer eventually for the next two I bought a HJC AND my latest an Arai X4 Tour these have been fine .
It's amazing what can be be done with proper application of materials science now. I think they are missing a trick here though. What I think they need is a biker cafe hookup next door. Hand in your lid, collect a voucher for a breakfast or a pie and cuppa and go sit on a nice comfy seat surrounded by like minded folks to shoot the breeze with :>)
I thought I put in the miles when it came to producing videos, but Chopsy is a way ahead of anyone I know when it comes to attention to detail and effort. Very pleased that you're still here to tell the story about your helmet, which I guess is telling about how a helmet is designed to perform. It's worth pointing out that the manufacturer you mention has just announced the launch of their new helmet, which is ECE 22.06 certified. I can literally count the number of helmets on the market today, that meet this exceptionally high standard, on one hand. These guys have catapulted themselves into a spot where they now have one of the safest helmets on the market. All the best. Martin
If you don’t know whether the damage is part of the manufacture or done in the supply chain it is a problem. Do you buy a helmet and get it tested before you wear it? Maybe they should be packaging the technology and supplying it to the supply chain so that images can be compared at different points. Trouble is how much would that add to helmet supply.
@@helmetinspection True, although that said, I used enough bubble wrap to swathe an aircraft carrier on one occasion, and the mail still succeeded in breaking an ear off a china cat. Nevertheless, I salute you for your very fine and vital work. Best regards from Burry Port, West Wales.
@@michaelarchangel1163 that's not a great experience. I've purchased a few peli-cases so customers can request to have one sent to them - if they want to use something that's indestructible. You can see it here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-23aRZaEy_N4.html Martin
Hi choppsie, good vid, when I took my advanced many moon's ago the police examiner roy used to tell me hit something head on at over 18 miles an hour you would probably have brain damage. Because your brain would dislodge it's self. He was a traffic motorcycle 👮♀️ cop.keep smiling 😃 .all the best mick 👍
It's a scary thought, but helmet technology is evolving. We see how this evolution is taking place when GP riders etc. come off at 100mph+ and in many cases walk away. I've been really encouraged to see some of the manufacturers recently introduce suspension systems into their helmets (e.g. Rheon / MIPS etc) to reduce rotational effects, which is now a requirement of ECE 22.06. Cheers, Martin
Interesting. Of course what it doesn't tell us is if the detected damage actually makes any difference in terms of protection? It might or might not have any impact. Especially since it only seems to test the shell and not the foam. Curious why you (or them or jointly) didn't just go out and buy a cheap £30 helmet from Lidl or Tesco etc.. for testing and destruction. I'm curious how the tech works on boats previously being the owner of a hand-laid up boat. It's never going to be uniform and will expand and flex differently in different areas. Anyway though it's an interesting video - cheers. 👍🏼
I've read about this before and qas sceptical ... and I still am. The fact that different parts of the helmet expand at different rates is very arbitrary. It also doesn't show if there's any compression of the EPS below the outer layer.
Thank you for posting. Great video which generates additional questions. Seems like the testing is qualitative and not quantitative. You test a helmet and based on some (potentially subjective) criteria it is deemed good or bad. Would be nice to have a quantitative criteria to achieve more objective conclusions. Another question is with today's manufacturing where companies are laying thicker layers of composite on certain areas of a helmet, it creates a non-uniform layer/thickness areas throughout the helmet. Because of the delta in helmet thickness, when the helmet is heated, does it cause un-even expansion of the shell resulting in a false negative result?
Hi @dsimon9. As Chopsy highlighted in the video, the equipment we were using was for the purposes of video production. It wasn't the actual equipment used to perform the tests. The actual tests are quantitative in nature and a fixed known temperature rise is used to excite the region under investigation on the helmet. The thermally induced strain within the monolithic composite skin is measured. The final images displayed are actually a two-dimensional representation of the detected flexural strain in the helmet. And so the quantified strain anomalies directly describe the state of the underpinning structure, variations in skin thickness show up, such as in the video, which can be attributed to, in this instance, cooling ducts. The temperature rise doesn't have to be that high, typically 1 to 2°C. When anomalies are identified we usually repeat the test several times just to confirm the presence of the defect. I hope this helps. Regards, John.
Great stuff as always... but if one is to send in a suspected lid how long does it take to have it checked and sent back? As if you only have one and need it for the commute it's going to be a bit of a problem
Once we receive your helmet, our turnaround time is 2-3 working days. You can select a 24hr return service when you're booking the inspection on our website which is only a couple of quid more.
That's a great turnaround and the 24hr service is even better for if your in a pinch just thought it would be good info for anyone considering using the service. thanks
Thanks for ding this video and has been really interesting and useful 👍 Think if I was to have my helmet tested I would drop it off and pick it up and not rely on a delivery company 🤣
What are your thoughts on us carrying out testing at helmet retailer stores? Pop into a local retailer, get your lid tested and see the process for yourself? Martin
Is any of that damage enough to render that AGV helmet finished, or is it still fit for purpose, that is the big question! How hard would you still have to bash that lid to get it to completely fail, and would your brain have already suffered catastrophic damage hitting the inside of your skull well before the outer helmet shell fails? Next question is, what % of motorcyclists die due to helmet failure against other injuries? And as it was said, do all brand new helmets pass this perticular test, or will fault normally be found? I'm not saying it's not a worthwhile service, but i am saying this opens up a lot of questions.
Exactly. I find it hard to believe that an empty helmet falling from 1m would render it unusable. Imagine what hitting something at 50mph with 20kg inside would do to it then. This inspection is good for areas which are constantly under stress, to show where week spots are and so on.
It is just a means to discover the structural integrity of a helmet. There is no such thing as "fit for purpose" where the purpose is crashing head first in to a tree. No two crashes are the same and no testing comes even close to testing a helmet in every possible scenario.
@@adolfshitler The presence of the year 1985 should arouse some suspicion! No!? In any case all of these tests are just based on artificially controlled testing of things like materials and form. They are not literally crash tested and no guarantee of protection is offered by anyone.
This is all good but you got to post it to them, like you said you thought the damage on your helmet was caused by being shipped, thrown about and so on. So sending helmet to them may show same issues, dont know how the courier is gonna look after your package.
Need to have a look at these guys. Had an off in my shoei hornet but don’t think I hit my head. Only mark is on the wrong side of the helmet on the peak to the side I landed.
@@helmetinspection yes wasn’t a bad one. Just slow speed on trails. Front lost grip at 15mph and put me on the ground on my side hence why I think my helmet hit the ground. Bike landed on my leg so did break that but apart from that all good.
