Full Face Motorcycle Helmets (Types of Helmets - Part 1 of 4)

Full Face Motorcycle Helmets

A full face motorcycle helmet is the most common type of helmet you’ll see on the road. This is the style most traditionally associated with what a motorcycle helmet “looks like.” It’s also the style that provides you the best protection.

It seems odd that this is a claim which would need to be defended, but one common claim you’ll hear among “anti-helmet” riders is that full face motorcycle helmets actually increase your risk of serious injury or death in a crash. The reasoning of this urban legend tends to go along the lines of “wearing a motorcycle helmet increases the odds of a broken neck” then citing such reasons as “the size of a helmet creates more leverage against your neck in a crash” or “the helmet adds weight that makes your neck break more easily, like an orange on a toothpick.” Most people who tell this also cite some personal experience like “I knew a guy who had a motorcycle helmet and broke his neck.”

So, rather than arguing, let’s look at the statistics.

First, let’s just deal with the broken neck claim. The first thing to say is that, yes, a motorcycle helmet increases the weight of your head. But the question is whether that increases your risks. Interestingly, some surveys of the medical literature show a wash when it comes to neck injuries. According to these reports, motorcycle helmet use seems to neither decrease nor increase the incidence of neck injury. And yet, that sort of makes sense. A helmet is protecting your head, not your neck.

Other reports, however, show a large decrease in neck injury amongst riders wearing motorcycle helmets. There is no support, however, for claims that motorcycle helmets actually increase head or neck injury. And most studies show significantly LOWER neck injury amongst helmeted riders involved in a crash. (see Sarkar, S., Peek, C., & Kraus, J.F. (1995) Fatal Injuries in Motorcycle Riders According to Helmet Use. Journal of Trauma, 38(2): 242-245. )

So if wearing a helmet doesn’t pose an increased risk to your neck, what about your head?

The leading cause of death in motorcycle crashes is head injury. Period.

(see: U.S. Department of Transportation/National Highway Traffic Safety Administration, State Legislative Fact Sheet)

Second, the NHTSA (National Highway Transportation Safety Authority) estimates, based on cold hard crash statistics, that a rider without a helmet is 40% more likely to suffer a fatal head injury and 15% more likely to suffer a nonfatal head injury than a helmeted motorcyclist. Add that up and an unhelmeted rider is 55% more likely to suffer either a serious or fatal head injury in a crash.

Is that a coin flip you’re willing to take?

Some would say yes, and there are understandable reasons some people choose to accept that risk. But please understand that the claims that wearing a motorcycle helmet actually INCREASES the odds of injury or death are just plain false. The facts support the undeniable conclusion that you are far, far safer with a motorcycle helmet than without one.

But look, I get it. There are some reasons people don’t want to wear a motorcycle helmet. And I sort of forgot that this post was going to be about full faced helmets, so let’s get back to it. How bout a convenient transition:

Some of the reasons people don’t like to wear motorcycle helmets have to do with the experience of using a full faced helmet.

There ya go, now we’re transitioned. Right then. Here’s a picture of a full-faced motorcycle helmet to the left, in case you're a newbie and need a visual here. (The helmet pictured is an Arai RX7 Corsair Full Face Helmet by the way).

So, let's talk helmets. A full faced helmet provides the best possible protection in the event of a crash, but for certain people there are some downsides.

First, if you live in a warmer climate, a full faced motorcycle helmet can get hot. Really hot. Fortunately manufacturers have provided some creative solutions, mostly involving vents in the helmet. These can do a lot of good, and a vented helmet is critical if you have to ride in hot weather, but it’s still true that these helmets can get hot.

Second, there is the “purity” argument. Part of why we all love to ride is the feeling of being connected with the experience. You all know what I mean. There’s a sense of being at one with the road and with the ride that you get when you’re on a bike that just can’t be reproduced in a car. And there are people who feel that a full face motorcycle helmet disconnects them from this experience. You lose the wind on your face, you’ve got a shield between you and the world, and you feel less connected with the ride. These are legitimate arguments, and they need to be balanced against the risks incurred by wearing a less protective helmet. I’ll be discussing all these other sorts of helmets in the posts to come.

There’s one final point before I wrap it up. And again, it’s not about telling you which motorcycle helmet to buy (though obviously my own opinion is clear). Rather it’s about understanding the risks and making your own decision with complete knowledge.

So the fact is this: statistics show that 35% of crashes involve severe impact to the chin area. The full face motorcycle helmet is the only design which provides protection in this type of crash.*

Ultimately the decision is yours, but it’s at least important to understand the consequences of the decision. So one consequence of not buying a full face helmet is a statistically significant increase in the odds of severe trauma to your mouth and jaw in the event of a crash.

Again, I’m not trying to scare anyone here, I just fully believe in helping people understand the variables involved in important decisions.

So, let’s recap.

Full Face Motorcycle Helmets - Pros and Cons

Pros: Hands down best possible protection. Keeps you warm in a cold climate. Huge variety of styles and colors.

Cons: Can get hot. Feeling detached from the “pure” riding experience. Some say reduced hearing (disputable).

*Much of this discussion also applies to “hybrid” helmets. Also known as modular or flip-up motorcycle helmets, which I’ll discuss in the next post. They’re sort of a variant of the full face motorcycle helmets, not entirely apart from the discussion here.

DOT Motorcycle Helmet

First time riders often don’t know what a DOT Motorcycle Helmet is. You hear the term tossed around and figure out it’s got something to do with safety, but what exactly does “DOT” mean, and what does it have to do with Motorcycle Helmets?

A DOT Motorcycle Helmet is a helmet that has passed the safety requirements and tests of the Department of Transportation. In states with motorcycle helmet laws, a DOT helmet is the minimum level of helmet you’re allowed to wear legally. The good news is that it’s extremely difficult to find one that ISN’T DOT approved since, technically, any motorcycle helmet sold in the US is required to have met the DOT requirements.

So what are these requirements, and what do they mean?

The build and design of a DOT Motorcycle Helmet can be mostly simply explained in terms of a few key factors.


Inner Liner:

Here we’re not talking the “padding”, but the actual liner, the material that protects your skull. About one inch of polystyrene foam tends to be what you’ll find lining the inside of a DOT Motorcycle Helmet, though this can vary slightly with helmet design. Whether or not you can see it or it’s covered with some sort of additional inner layer, you’ll know a motorcycle helmet has this because, well, it’ll be thick. If you pick up a helmet and it’s only a thin plastic shell, it’s barely going to protect you in a fall, and it’s definitely not a DOT Helmet.
The polystyrene foam is what breaks instead of you in a fall, so it’s important! And the Department of Transportation recognizes this. It’s a simple concept, straightforward (not like learning to speak German): a motorcycle helmet with thicker foam will protect you better in a fall, and DOT has requirements for this.


------Unsafe Helmet ------------------ Safe Helmet ------

Next, Rivets and Chin Strap:

This one’s basic: a DOT Motorcycle Helmet has met the basic requirements for it’s rivets (those metal things holding it together) and chin strap. In other words: it won’t fall apart when you fall.


Helmet Weight:

This isn’t a requirement so much as a clue. When you pick it up, a DOT Motorcycle Helmet is going to weigh in the neighborhood of three pounds or so. The point isn’t the exact weight, the point is that it doesn’t feel absurdly light (i.e. 1 pound). If a motorcycle helmet weighs a pound, it’s not DOT approved.


Helmet Design and Style:

Protrusions aren’t allowed to exceed two-tenths of an inch on DOT Motorcycle Helmets. This is probably to prevent anything that might snag or catch on the ground and torque your neck in a fall, though I don’t have that on authority. You might run into what’s called a “German Army” style motorcycle helmet. If it’s got a giant spike sticking up out of the top, it’s not a DOT Motorcycle Helmet. However, there are some German style helmets on the market you can find that have been DOT approved, you just have to stop around.

There are different ways to see if a motorcycle helmet is DOT approved. To start with, if it’s a full face motorcycle helmet, it’s probably DOT approved. Most novelty helmets aren’t full face. The other (main) way to check is to look for the DOT sticker. DOT helmets are required to have this sticker on the outside, rear of the helmet. Note, however, that a fake sticker can be placed on a motorcycle helmet. So if you’re not buying from a reputable dealer, you might want to do a bit more research to double check: like looking up the helmet online to see if it’s DOT approved, or checking for the stickers of other organizations such as SNELL or ANSI.

So there ya have it, the basics of a DOT Motorcycle Helmet, what it is and what it means.

Motorcycle Helmets Guide Online

Welcome to the Motorcycle Helmets Guide!  This site provides information on Motorcycle Helmets, as well as reviews and tips on buying a Motorcycle Helmet.  If you have questions not covered here please feel free to email your question to motorcycle.helmets.guy@gmail.com  My goal is to provide you with quality content that can make your process and decision much easier.  Buying should be fun, not stressful.  So enjoy, and thanks for reading!

Motorcycle Helmets

If you're confused trying to learn about Motorcycle Helmets, read on!

Shopping for Motorcycle Helmets can be a stressful ordeal. After all, Motorcycle Helmets aren’t like shoes, right? When you're shopping for Motorcycle Helmets, you are, in a way, shopping for your life! No one wants to trust their cranium to just any old piece of plastic, after all. And with so many Motorcycle Helmets on the market, it's easy to get overwhelmed.

But there's good news. Most Motorcycle Helmets out there actually do a similar job of protecting you should the worst happen IF you do your homework to find the right Motorcycle Helmet for you. "Homework??" You say. Don't worry, it's the fun kind. After all, Motorcycle Helmets are an important part of our riding experience, and why are we out there to begin with? Most of us would say, at least in part, to have fun. So when we're shopping for Motorcycle Helmets, that should be fun too!

Alright, enough rambling.
So, first and foremost, you only want to shop for Motorcycle Helmets that are certified. What does that mean? Well, there are two types of certification for Motorcycle Helmets: DOT and SNELL.

DOT Motorcycle Helmets 

These have passed the "minimum" safety requirements as stipulated by the Department of Transportation. Motorcycle Helmets that have been through this process will have a DOT sticker somewhere on the helmet (usually at the bottom rear).

SNELL Motorcycle Helmets 

These have undergone the additional certification process of the SNELL organization. And (surprise surprise), SNELL-certified Motorcycle Helmets will have a SNELL sticker on the helmet.

"Important Point 1" (dramatic music): there are custom Motorcycle Helmets out there that haven't been through any safety certification. These Motorcycle Helmets can look really cool but I suggest against buying them. Why? Because there are plenty of cool-looking Motorcycle Helmets on the market that *have* been safety approved, and looking cool is never more important than riding safe.

Important Point 2:

SNELL Motorcycle Helmets are not necessarily any safer than DOT Motorcycle Helmets!

"But I thought SNELL motorcycle helmets were tested more rigorously??"

Well...yes, they are. But due to a lot of boring technical details I won't get into here, the gist of it is that certain design features of SNELL Motorcycle Helmets may counteract any additional safety gained. There are differing opinions on this, and studies have been done by different groups, but the basic point is:

Both DOT and SNELL Motorcycle Helmets are safe enough to wear confidently on the road.

And that's really what we're looking for, right?

So, we’ll leave it there for today. Next time I’ll look at what to consider when shopping for Motorcycle Helmets. Until then, remember that Motorcycle Helmets are the most important gear we wear, so wear it proud!

Shoei Helmets

Many people tend to think of Shoei helmets as the best of the best.  To understand why, it’s important to explain a bit of the background of these motorcycle helmets.  Shoei is a small, quality Japanese helmet manufacturer that’s been making their helmets since 1958.  So the first thing Shoei helmets have going for them is a decently long-standing legacy.  Even more than history, however, is that fact that Shoei helmets have a reputation as being at the leading edge of motorcycle helmet innovation.

The main driving force behind the technological innovations you’ll often find in Shoei helmets is the fact that the company history is firmly rooted in motorcycle racing.  As is typically the case, intersections between the commercial and racing industries tend to trickle down to the consumer market in the form of highly advanced, over-engineered motorcycle helmets.  In other words, because most Shoei helmets were first designed for motorcycle racing, their features, shape, weight, etc all tend to be substantially more than what’s needed by most riders.

And, naturally, that’s exactly what many riders want.  And make no mistake: Shoei helmets are great helmets.  Hands down.  This little company makes a top-notch line of motorcycle helmets that can be a true joy to wear and behold.  The thing is, this isn’t without its price.  And the price is, well: price!  If you want a Shoei helmet, you’re gonna pay.  Shoei helmets often cost three, four, even five times as much as more economic alternatives.  If you’re one of those lucky people for whom price is no issue, then by all means, spend to your heart’s content.  

But for the rest of us mere mortals, there’s a critical point here you need to understand: just because Shoei helmets are more expensive doesn’t mean you’re getting better protection for your head.  These days, there is such an abundance of less-expensive, quality motorcycle helmets on the market that you simply don’t need to spend all that money on Shoei helmets if you don’t want to.  And it’s more than just competition too.  As I’ve discussed in other posts, and will continue to discuss in the future, finding the best motorcycle helmet for you isn’t a question of finding the most popular brand.  Rather, it’s a question of learning the unique characteristics of your own head, and then matching those to your own particular “best motorcycle helmet”.

So, yes, it’s true that Shoei helmets are great.  And I’d be lying if I said I didn’t drool over them sometimes.  But the simple fact of the matter is that as long as you’re dealing with DOT or SNELL approved motorcycle helmets, you’re not going to be getting much (or any) additional safety by simply buying a more expensive helmet.  In fact, if you spend more money but get a motorcycle helmet that’s ill-suited for your head, you may actually get *worse* protection than if you’d bought a less-expensive, better-fitting alternative.  So, for those of you who don’t have money to burn, I leave you with this.  Next time you’re at the store, walk right on by those pretty little Shoei helmets and find something uniquely best for you.

Motorcycle Half Helmets | Types of Helmets - Part 2

Alright folks, today we’re gonna talk about motorcycle half helmets, especially the pros and cons.  I’ve gotta run out the door, so today’s entry is gonna be a short one.

By the way, the image shown is an hjc motorcycle helmet, the model is the CL-21 Reign Half Helmet.

PROS:
- Style.  Lots of riders like the look of motorcycle half helmets, and there’s a lot of truth to this.  When you’re cruising along the highway, there are few helmets that have as cool a “low rider” feel to them as half helmets.

- Visibility.  A half helmet doesn’t obstruct your peripheral vision as much as a full face helmet.  There have been a lot of advances in full face helmets with respect to visibility.  I know my Gmax helmet has great peripheral vision.  Nevertheless, a half helmet doesn’t have any material around your eyes, so again, you’ve got that real sense of unobstructed vision.

- Experience.  Riding a motorcycle is a lot about the experience of getting onto that bike and feeling connected with the road and the world around you.  A motorcycle half helmet lets you get that wind in your face without completely sacrificing safety and protection.

- Ease of putting it on.  Sometimes when you’re hopping on your bike for a quick ride, it can feel like a hassle to pull on a full face motorcycle helmet, even it is that pretty little Shoei helmet sitting on your table.

CONS:

- Safety.  This is the obvious number one con.  A half helmet simply doesn’t afford you nearly as much protection when you get on your motorcycle as a full face helmet does.  A huge percentage of motorcycle crashes involve impacts to the chin and mouth area, and a half helmet provides exactly zero protection.  So, not to be too graphic or anything, but if you’re unlucky enough to be involved in such a crash, you’re pretty much gonna get your mouth and jaw bashed in.  On the other hand, there are always risks to getting onto a motorcycle.  We should all know that and accept it.  So for many people, the risks involved in wearing a half helmet are simply an extension of the risks we all accept when we get onto that bike and ride away.

- Bugs and rocks.  There are few things as unpleasant as getting a fat ol’ bug in the mouth or eye when you’re cruising down the highway.  Unlike a full face helmet, a motorcycle half helmet ain’t gonna do a thing to stop this from happening.  The same can be said for rocks.  Broken cheek bones are not unheard of when a rider comes up beside a semi and gets a flung rock in the face.

- Cold weather.  Trust me on this one, if you live in a cold weather state, you do *not* want to wear a motorcycle half helmet during the winter months!!  It’s cold, and you can get frostbite in about two seconds flat.  (On the other hand, if you live in a hot climate, a half helmet may be a welcome relief from the sometimes stifling heat of a full face helmet).

Well folks, there ya have it.  The short and sweet overview of motorcycle half helmets.

Novelty Motorcycle Helmets

Novelty Motorcycle Helmets are hard to find these days. But if you’re determined to find one, you can. I suppose the first question to ask then, is what, exactly, is a novelty motorcycle helmet? The most basic way to look at it is that a novelty motorcycle helmet is one that hasn’t been tested by certifying organization such as DOT or SNELL, and isn’t made by any of the major motorcycle helmet manufacturers such as Shoei, Arai, Bell, KBC, HJC, etc etc.  More fundamentally, however, novelty motorcycle helmets tend to be sought after by people looking for weird, cool designs, whether it’s a police helmet knock-off, german motorcycle helmet style, or whatever. A lot of vintage motorcycle helmet designs, for example, can now only be found in the form of novelty helmets. This is because a lot of those vintage designs are incapable of passing the rigorous safety requirements of DOT or SNELL. And that really brings us to an important point: if you buy a novelty motorcycle helmet, you need to understand that it literally might not be protecting your head at all.

The Department of Transportation has really cracked down on novelty motorcycle helmets in recent years for this very reason. Unlike certified, full-face helmets (or even certified half or open face motorcycle helmets), novelty motorcycle helmets have absolutely no regulation whatsoever, and are often constructed with cheap, shoddy materials and little to no protective foam.

And hey, if you’re cool with that, then no worries.

Just understand what you’re buying. Novelty motorcycle helmets, whether used or new, for sale online or in a retail store (though good luck finding one there) exist for one purpose, and one purpose only: to look cool and add a bit of flair to your motorcycle gear. So if you’re a rider who’s comfortable sacrificing safety for the cool-factor, then a novelty motorcycle helmet may work just fine for you.

Okay okay, so now that I’m ranting about DOT and SNELL regulations, where can you actually find novelty motorcycle helmets? Well, where are you now? No, not literally, you twit. Virtually (dramatic music). Yes, you guessed it, the internet. If you want to find novelty motorcycle helmets, then buying online is virtually your only remaining hope. Even the stores that sell discount motorcycle helmets don’t tend to carry novelty helmets any more. They don’t wanna get penalized by DOT I suppose.

The sky is pretty much the limit online. There are any number of novelty motorcycle helmet retailers that can be found by pawing around on the web. And make no mistake, the designs do get creative. Whether we’re talking the good ol’ german motorcycle helmet designs, or even wilder stuff than that, if you crawl around long enough, you can probably find it. So if novelty motorcycle helmets are what you’re looking for, don’t let me stop you!

Best Motorcycle Helmet

Finding your Best Motorcycle Helmet starts with head shape.

The best motorcycle helmet for you might not be the best motorcycle helmet for someone else. That should come as no surprise, because we’ve all got different shaped heads! So a motorcycle helmet that fits me great, even if it’s your size, might feel strange or uncomfortable for you. Which conveniently brings us to an important point: wearing a motorcycle helmet is about safety, but if you’re not comfortable you can’t be safe.

Just think about it: if you’re riding along the highway with a painful pressure point on your forehead, that’s probably not the best motorcycle helmet for you. Because apart from being painful, it’s distracting. And distraction adds unnecessary risk to your riding experience.

Right then, so if our ongoing quest to help you find the best motorcycle helmet FOR YOU, we start with head shape.

Humans have all sorts of different head shapes, but the mains ones are: round, earth, oval, egg, reverse egg. And since motorcycle helmets have different internal shapes, it’s important to find one that fits your head shape.

Round heads look roughly circular from the front; earth heads are wider than they are tall (think Stewie from Family Guy); oval heads are taller than they are long (like an oval :) egg heads are wider at the top and skinnier at the bottom, and reverse egg heads are wider at the bottom and skinnier at the top. Finding your best motorcycle helmet means finding one that doesn’t fight against your head shape.

Unfortunately, there are no hard and fast rules here. Most motorcycle helmet manufacturers give only spotty information at best on the internal shape of their helmets. Which means (dum da dum!) you have to try them on! (Imagine that, eh?)

Oh rather...you might have to try them on. Older folks don’t tend to be comfortable buying a motorcycle helmet sight unseen. But in my experience if you’re willing to do your research, you can actually buy a motorcycle helmet online without ever trying it on. That’s what I did. And I love my helmet.

So if you’re trying to find your best motorcycle helmet online, you need to find reviews that discuss head shape. Now, like I said, the manufacturers with the best motorcycle helmet websites will already have this information available. But if you can’t find it there, you have to do some more digging. Luckily for you, in the weeks and months ahead I’ll be posting a lot more useful information right here on my website on how to find the best motorcycle helmet for you, including the internal shapes of different brands of helmets.

In my next post, I’ll get deeper into how head shape and sizing should factor into finding your best motorcycle helmet.
