I will say, when I had my high side on the track with my R6, I flipping end over end in the air and landed on the back of my head and upper back, the speed hump, since my suit simply has padding in the hump and none of that fancy stuff, absorbed all of the impact when I hit the ground and I walked away with no injury after nearly a 50 mph crash. Say what you want about them, but that little thing made for me to look cool, pretty much saved me from future back problems😂
The problem with motorcycle crashes is that there are so many scenarios and their respective forces to take into consideration. Everything from a low speed low side to overcooking a turn on the Mountain Course. They all have different ways to spit you out and throw you on the road. Plan for the worst and hope for the best.
But to say they do nothing for safety is a lie. I walked away from a 100mph crash (lowside) in my opinion due to this hump... and bit of padding where it can be applied will help when rolling down the road.
I could have sworn it was for whiplash and neck protection. I was shaking my head until you cited the peer reviewed study and explained the history of it. very well produced video!! especially the note of the airways being obstructed,
Thank you so much for a definitive, scientific answer! I get asked this question all the time when I'm on the street with my race suit on... Now I know exactly what to say!
Great video, Mike. I also saw a video featuring the late Dr. John Hinds (road-going, first-response doctor from Irish and British road racing series) where he actually said (like in the article your quoted from) that the speed hump needed to be removed before you could intubate a crashed rider. So it being a safety measure is very questionable, like you also state yourself.
I seem to remember a commentator, (I think MotoGP), a couple years back explaining that the "hump" was packed with an airbag, which deployed immediately with the aim of helping to protect from spinal injuries, when electronic telemetry within the suit sensed the rider making "sudden, unrealistic changes in trajectory". In other words, as soon as they were airborne, usually from a high-side. Ofc, being a commentator of one of the most prestigious motorcycling events, I had no reason to doubt the statement, and in fact, it made some sense. Apparently not, though. It would be a perfect way, with today's technology, to make good use of the hump though...
The suit does pack with ‘airbag’. Whatever he said was true for current motorcycle tacing suit. However, not sure about the hump part. Riders suit will blow up to cushion them during fall.
If anyone hasn't seen any of Dr John hinds speeches please go have a look, he was the flying doctor at the Irish road races and sadly lost his life helping others. So if you have a few spare minutes just search Dr John hinds and watch one of his speeches on how medics treat bikers
You know, I didn't even think about a water bladder. I knew about the Aero and computers, but I never even thought of water. I'm glad this actually taught me something.
To be fair, nothing is safe on a motorcycle. We try to mitigate it, but it still is ultimately extremely dangerous. But it's a decision, each of us decides that it's fair to trade safety for engagement and emotions
I actually like the hump because manufacturers use it to channel ventilation for your back. Vents go from the hump directly down to where my back protection usually gets sweaty. Sweet!
@Mike on Bikes yes, the hump is totally to do with aerodynamics. (Originally) I know as one of my friends helped finalise and test the design of it it along with some engineering university students before it went mass market. They even created a racing motorcycle to go along with it that had a huge round/hump shape as the seat unit too that followed on from the width of the riders hips/butt (It was called the Ensign and I thiiiiink it was a 125 prototype. Long time ago) It was ugly as anything though too. Was bright blue and had a really fat looking ass to it 😁
There is also another point, it helps in the entire Aerodynamic of the bike and the rider all together. The air flow will be smooth with any hurdles in between which is disturbing the aerodynamic air flow.
Hi Mike! I did the same video on my channel in Italian a year ago and I came to your same paper! :-D It state that the hump it's actually dangerous because in case of a broken bone in your spine it can put it a bad position and cause damage to your nervous system.
Awesome sir, thanks for the explaination. If you don't mind, I would like to know more about EXUP also. I notice it's there on MotoGP bikes, but most riders are keen to ditch them off.
Few years back I crashed on the track. I was strapped onto a backboard with the hump still under my neck, that nearly did more damage to my neck than the crash.
I've got a Triumph race jacket with the hump and yep it's for airflow over your body but the hump does something else for me ,,when you get over 200kms the hump pushes the back of the helmet and stops the front of my helmet from coming up from wind speed when I'm tucking right in , makes it really comfortable at really high speeds
Hello Mike. Thanks for the video. I thought the hump helps to stop your head from tilting too much backwards. Like it would prevent a whiplash. Next time you put on your leather suit and helmet try to tilt your head backwards and you'll feel that you can't move any further because the back of your helmet be stopped by the bump.
@@MikeonBikes I don't have any references. It's just my personal assumption. And I came to that conclusion while I was stretching and realised that back of my helmet bumps into the hump at a certain point 😂. But now that I think about it I actually have an old racing suit without a hump I am going to try it and see if it makes any difference compared to a racing suit with the hump. But first I have to find the old suit.
My bks jacket says on it that it is NOT a safety feature... It increase s the chance of a broken neck and of a blocked airway but it does seem to reduxe drag
My street/track leathers have a hump and its always annoyed me. Hard to wear backpack and i feel a bit "try hard". Unfortunately not many manufacturers offer leathers without one.
My Dainese Super Speed 3 has a mini hump that doesn't affect my backpack. Combine it with Alpha pants and you have a good two piece suit for the street. On track or riding hard on the street you should be wearing a one piece suit without a backpack.
Yeah my mates got the same and it seems to be a bit more convenient. Theres a mountain pass between work and home so i prefer to wear leathers, 2 piece is more manageable for the street, but yeah 1 piece is 1st thing on my list for next years race season
I always wondered if it served additional purpose or not. And i knew a rider who removed the padding, put his hydration pack in it. Seemed to work but eventually had to get rid of the suit after bad crash and gave up riding.
Aerodynamics was my understanding of the hump too. But I’ve seen the myth of protection too. Personally, I don’t want to look like a racer because I’m not. However, so many leathers have a hump, that it’s harder to find the top leathers without one. If you want maximum safety, get an airbag inside your leathers.
So I am by no means a specialist in the kinematics of a motorcycle accident, nor the typical mechanisms of trauma incurred by riders - but I am a fifth year medical student and I have spent quite some time working in one of the busiest trauma units in the world. My impression is that the hump probably offers nothing in the way of protection for the back, head or neck - particularly since many of the internal injuries are caused by rotational/sheer forces and rapid local/global deceleration rather than any sort of impact that the hump could conceivably interfere with. Just my 2 cents, and I really appreciate your content, Mike!
I get the impression anyone who thinks a hump is going to help the spine or neck hasn't worn a hump suit. I will never forget just how awkward and uncomfortable it felt on my back when I first sat in a chair with one. Laying down would be just as bad. Frankly I assumed everyone could see it was purely for aero. I do notice a little less pressure on my helmet at speeds (140mph or so) and I'd imagine on the road it might make a little spinal cushioning, but there are far better and less obtrusive devices if safety is the priority for sure. It does look cool though, just as long as one doesn't need to wear the suit for any social appointments.
Remember when superbikes used to have seat humps, Oh and I think MCN (might not have been) did a test on how to make your bike faster, Nitros vs Gearing Vs Seat hump, they used Yamaha xj600 Diversions lol. Speedhump was the largest topspeed increase by a long way. Abarth did a simular thing with the boot lid on the 500 once upon a time.
That was a great commentary, esp liked you getting into the math, physics & visual aide (the pillow) u sir have impressed me. Keep up the educated posts.🤘👌👍
Must admit, I thought it was a safety hump as well as being an aid to aerodynamics. However, anything that makes you go faster and still looks cool, I’ll take that as well. Enjoying the channel. Keep up the good work! Graham @nctrackattack
they are absolutely a safety device, on your spine protecter, it usually tapers off at tail bone/below or above mid/upper chest. the hump provides more material between you and the ground.
@@MikeonBikes in addition, youre looking at the impact casued with/without hump, youre not looking at hyperextension. "The back protector with CE-rated armor lives inside the suit, nearer the rider's body. There is one more purpose, where the top of the hump also keeps the helmet from being thrown back beyond the range of movement of the human neck. "
i tought the hump was for a small hydration pack to be honest since the AGV pista helmet has a water tube built in i tought that's where you would store water in a race suit
Makes a lot of sense. But I too was thinking along the lines of the hump providing cushion especially for the helmet snapping back against the neck. I was particularly reminded of my very first fullface helmet which at the time was the rather off brand more obscure Shoei. This was in early 70s and thismodel helmet had no she'll in the back lower part of the helmet and instead had black styrofoam the whole idea being there was no hard edge to lever back into your neck ...Lol bought that idea literally as did many others but I guess science was not with that either as it dissapeared
i don't have racing leathers so when i go out for a high speed hoon i pack a backpack full of jumpers and towels and it stops my head from getting badly buffeted....
you could use the helmet that is using rear spoiler to give better illustration of reducing turbulence. but great vid anyway, didn't know there is a journal about that.
Here’s another one I’ve wondered about in the past and someone else asked in the comments: Why don’t we see widespread adoption of HANS devices for motocyclists? Is it because to effectively protect that area, it would overly negatively affect head movements?
A similar type of device, called a neck brace, is used in dirt bike riding. I know some folks who ride sport bikes with neck braces. I found a study showing that neck braces are not that effective for impact speeds above 6.5 m/s or 14.5 mph. So it makes sense they wouldn't be used for sport bike riding for that reason. link.springer.com/article/10.1007/s12283-018-0268-z
@@MikeonBikes spot on - even the manufacturers of those neck braces can't justify them. For a race car they make sense as the head can be restrained, but on a bike the data suggests they can make injuries more serious EDIT: ruclips.net/video/U6UfHO7jcHk/видео.html
The late John Hinds mentioned speed humps in one of his (excellent) presentations on emergency medicine at races in Northern Ireland. Search RUclips. As I recall, it was all bad news, due to the kinks in spinal position and airway they create when laying down. His team would cut them out.
My friend talked to a isle of man Tt medical rider and he said that it's a pain the the ass. It's bad for a broken neck and airways, as the journal states
I have been riding motorcycles some 30 thousand years or so. I always thought the hump was to protect rider's necks. Well, no matter how much you think you know, there is always someone about who can prove to you that some of what you think you know is bullshit.
This is really great content and well made :) I create motorcycle related content as well. How do you get the crash videos to incorporate into your video? I would love to have that ability but am not sure how to get the content nor how to make it legal to incorporate. Thanks for the content! Best - Liz
Hey Liz! Assuming you are in the USA, there are fair use laws which allow you to use copyrighted content as long as your use of it is transformative. Transformative uses are those that add something new, with a further purpose or different character, and do not substitute for the original use of the work. This is how for instance channels that review movies can actually show you clips from the movies, because their use of that copyrighted content is transformative. My use of clips from MotoGP is transformative, because I either comment on it or use it to educate people on something that can be observed in the clips.
How extra volume on the back could serve as impact protection for the spine after a high-sider is too obvious: Don't just make it a massive lump of foam, but make it an air tight semi-flexible bag with small vents that will allow air to escape under pressure. Shock absorber, there you go. a few inches gained for cushioning an impact will make a vast difference in the effect. That's why everyone assumes the humps are safety features. That twenty-plus years passed without any "Specialist" actually getting the extra safety *from* those features tells me that among those experts, there are way too many not really worth their income. I also can't understand why there is no means to connect helmets and suits to limit the range of neck movement in racing gear. Why are there no protective features for the neck, where an impact to the larynx can kill you in a few seconds?
Turns out that the mechanics of that are not so straightforward - very easy to accidentally create more leverage on the neck during an accident. ruclips.net/video/U6UfHO7jcHk/видео.html
I've always thought of it as some kind of aero thing cause when you see drag races, especially the illegal ones, they always lean in to lessen drag. I don't get the science behind it though.
Anything that sticks out in the windstream creates drag. It also creates turbulence which can make the bike's handling become unpredictable. NASCAR is a good teacher here, as Dodge learned that the rear window on the 1968 Charger generated lift that affected the cars on the big tracks. Chevy learned this when Dale Earnhardt raced the Monte Carlo with the squared off rear window.
I've seen it several times on your channel and i have to ask. Are you the owner of that RS250? I really would like to see an onboard video of ot. I too own a little GPR 80 which is technically little brother of RS250
Ok so basically... Perhaps it's not originally put there as a safety feature however as clearly displayed in the crash footages it absorbs much of the impact wrench you fall on your back and it also helps keep your upper back and shoulders off the pavement which almost in a natural reflex causes the rider to also lift his head off of the asphalt. So.... I guess it is a safety feature. Let's put it this way, if it only helped with aerodynamics and possibly increased chances for sightly worse injury, out of all the accidents that happen in GP and TT, even 00.001 chance that someone got EXTRA hurt because of it then it would immediately be outlawed so clearly the benefits are definitely there.

I found a study showing that neck braces are not that effective for impact speeds above 6.5 m/s or 14.5 mph. So it makes sense they wouldn't be used for sport bike riding for that reason.

@@MikeonBikes spot on - even the manufacturers of those neck braces can't justify them. For a race car they make sense as the head can be restrained, but on a bike the data suggests they can make injuries more serious EDIT: ruclips.net/video/U6UfHO7jcHk/видео.html
Mike on Bikes thanks! I had a feeling there’d be a reasonable explanation.
The late John Hinds mentioned speed humps in one of his (excellent) presentations on emergency medicine at races in Northern Ireland. Search RUclips. As I recall, it was all bad news, due to the kinks in spinal position and airway they create when laying down. His team would cut them out.
I thought it was to keep the neck from snapping back too far. Kind of a whiplash head thing on car seats.
On an Aprilia RS 250 it allows you to carry spare knees! I still miss mine.
Thanks for info !
Great info! Thank You!
I don't think I ever thought of hump as a safety device
Do you wear airbag wests?
please inform me if im wrong, but why dont road bike racers wear those neck braces like mx and mtb riders?
I thought it was an air vent to keep ur back cool lol
I thought this suit is used for practicing wheelie too just incase you loop out.
My friend talked to a isle of man Tt medical rider and he said that it's a pain the the ass. It's bad for a broken neck and airways, as the journal states
In the first time was developed for aerodynamics, later for safety. First dainese second alpinestars.
I love your hair, nice vid bro
the hump is important for aerodynamics and makes the helmet calm at high speed
I noticed they came in after Wayne Rainey*s crash in GP 500 around 93....then got popular with road riders....
but will it help in case you crashed? surely its not a primary function, but if it helps, why not have it?
I have been riding motorcycles some 30 thousand years or so. I always thought the hump was to protect rider's necks. Well, no matter how much you think you know, there is always someone about who can prove to you that some of what you think you know is bullshit.
This is really great content and well made :) I create motorcycle related content as well. How do you get the crash videos to incorporate into your video? I would love to have that ability but am not sure how to get the content nor how to make it legal to incorporate. Thanks for the content! Best - Liz
Hey Liz! Assuming you are in the USA, there are fair use laws which allow you to use copyrighted content as long as your use of it is transformative.
Transformative uses are those that add something new, with a further purpose or different character, and do not substitute for the original use of the work.
This is how for instance channels that review movies can actually show you clips from the movies, because their use of that copyrighted content is transformative.
My use of clips from MotoGP is transformative, because I either comment on it or use it to educate people on something that can be observed in the clips.
@@MikeonBikes Awesome! Very helpful. How do you obtain the clips?
I had no idea there were airbags in the suits now.
Thats informative. Great vid!👍👍👍
How extra volume on the back could serve as impact protection for the spine after a high-sider is too obvious: Don't just make it a massive lump of foam, but make it an air tight semi-flexible bag with small vents that will allow air to escape under pressure. Shock absorber, there you go. a few inches gained for cushioning an impact will make a vast difference in the effect. That's why everyone assumes the humps are safety features. That twenty-plus years passed without any "Specialist" actually getting the extra safety *from* those features tells me that among those experts, there are way too many not really worth their income.
I also can't understand why there is no means to connect helmets and suits to limit the range of neck movement in racing gear. Why are there no protective features for the neck, where an impact to the larynx can kill you in a few seconds?
Turns out that the mechanics of that are not so straightforward - very easy to accidentally create more leverage on the neck during an accident. ruclips.net/video/U6UfHO7jcHk/видео.html
I've always thought of it as some kind of aero thing cause when you see drag races, especially the illegal ones, they always lean in to lessen drag. I don't get the science behind it though.
Anything that sticks out in the windstream creates drag. It also creates turbulence which can make the bike's handling become unpredictable. NASCAR is a good teacher here, as Dodge learned that the rear window on the 1968 Charger generated lift that affected the cars on the big tracks. Chevy learned this when Dale Earnhardt raced the Monte Carlo with the squared off rear window.
Love the vid cuz the Aprilia...
I'm kinda a fanboy.
Thanks Mike!
PS... Great video bro!
I've seen it several times on your channel and i have to ask. Are you the owner of that RS250? I really would like to see an onboard video of ot. I too own a little GPR 80 which is technically little brother of RS250
Ok so basically... Perhaps it's not originally put there as a safety feature however as clearly displayed in the crash footages it absorbs much of the impact wrench you fall on your back and it also helps keep your upper back and shoulders off the pavement which almost in a natural reflex causes the rider to also lift his head off of the asphalt. So.... I guess it is a safety feature.
Let's put it this way, if it only helped with aerodynamics and possibly increased chances for sightly worse injury, out of all the accidents that happen in GP and TT, even 00.001 chance that someone got EXTRA hurt because of it then it would immediately be outlawed so clearly the benefits are definitely there.
