Following is a list of all of the motorcycle helmets reviewed on webBikeWorld.com grouped by shape.

Over the past 15+ years, we have developed a subjective classification system for helmet internal shapes.

Finding the correct shape to match your head is crucial for both safety and comfort.

The so-called “best” helmet in the world is worthless if it doesn’t fit, and sometimes a less expensive helmet will fit better than a helmet costing several hundred dollars.

Finding the “perfect” fit is sometimes extremely difficult.

For example, if I didn’t try an Arai Quantum II, I would have never known that it is the perfect match for my head shape.

I was fortunate to find a very knowledgeable sales person in a well-stocked Arai dealer, who helped me find the correct fit and then swapped out the cheek pads to custom tailor the fit even more.

Our 7 subjective helmet fit shapes run from narrow to round, with a “neutral” shape in the middle.

A “neutral” shape is a bit of a compromise; i.e., it is designed to fit a majority of head shapes. Seeour report on the Hohenstein Institute head shape study, which confirms the webBikeWorld head shapes described below.

It’s assumed that head shapes very roughly follow a standard distribution and, when plotted, probably follow a “bell” shaped curve.

Of course, this is only a supposition, but it’s based on a detailed study of motorcycle helmet fit, evaluating over 120 helmets and discussing the topic with hundreds of motorcycle riders over the past 10 years.

Frequent webBikeWorld visitors know that we sometimes use this analogy to describe helmet fit, and our 7 helmet fitment types were derived from the Gaussian function:

Notes:

  1. This is not an exact science.
  2. Sizes and shapes are not consistent between brands or even helmets of the same brand.
  3. Shapes can vary between different sizes of the same helmet.
  4. Fit is different as helmet sizes change.
  5. Manufacturers may change the internal shapes over time.
  6. Human head shapes vary considerably and individual features make helmet fit difficult.

From “L.L.” (April 2015): “Not sure I trust your analysis of the helmet shapes. I have a Shark Evoline (first gen) an HJC Sy-max (first gen) and both are either round or lean heavily in that direction. Both fit perfect (size small).

I recently tried on an HJC Sy-Max III in a small and could not hardly force it on my head. I then ordered a medium and it was way too tight also (head size 56 cm falls into the sizing guide of small). I wore it for an hour and had terrible pressure points and had to return it.

I called RevZilla and they said the new Sy-Max III is definitely oval shaped but the old Sy-Max was round. The are obviously correct. You list all three (I, II, and III) in the same category, leaning toward round, which they aren’t and you list the Shark Evoline leaning more toward the oval by one category, which it isn’t…it’s just as “round” as my old Sy-Max.

That sure makes it hard to buy a helmet online as it seems more run toward oval now than toward round. I’m going to try a G-Max G54 next, then the Speed and Strength SS1700 last (as that was recommended as a round helmet) but you don’t list either of those.”

Editor’s Reply: You bring up an interesting topic. There are several issues here; first, each head shape is different and the listed internal shapes are general guidelines. Slight differences in actual head shapes can and do change the way a helmet fits.

There just is no absolute guideline when it comes to finding the correct fit. This is why we always tell people to try as many helmets as possible and in different sizes. That’s the only way you’ll really get a good “feel” — and that’s what it is — for which helmets fit.

Another thing, the manufacturers definitely change internal shapes over time and sometimes even during a production run. We have reported recently that many of the manufacturers — like Arai — have moved towards a more “neutral” internal shape. So the helmet shapes may have changed since the webBikeWorld review was published.

And head size matters when it comes to evaluating the internal shape. The shapes are much more noticeable when you try one size larger than normal, because the padding isn’t as tight and it lets you feel the inside of the helmet.

And one manufacturer’s idea of a size “M” may be different from another manufacturer’s. Some manufacturers use different sizes for S, M, L, XL, etc. Example: SCHUBERTH uses a non-standard jump between their size L and XL. All of this means that the head size also matters when you’re evaluating the internal shape.

The internal shape can feel quite different, depending on which size helmet you’ve tried, which brand and even which model. Each helmet has particular quirks and sometimes you have to move up or down in a size range, which will either mask or amplify those quirks and pressure points.

You say you have a Shark Evoline and HJC Sy-Max and “both are either round or lean heavily in that direction”. We listed those as neutral to round, so we’re in agreement there. The Sy-Max II and III we listed as “slightly round”.

But the shell stiffness and construction were changed as the Sy-Max evolved, thus a more modern Sy-Max feels different than the previous versions, because the shell may not flex as much or in the same way. This can mean that a head size that is borderline or that has some slightly non-standard shape will suddenly feel tighter, as you report.

I don’t know about the RevZilla folks, but I’d bet for sure that a phone rep hasn’t worn and studied the 325+ helmets we have over 15+ years.

Bottom line? As you can see, this is a very complex issue with many variables. If we knew exactly how to match a helmet to each rider’s individual head shape, that would be fantastic…and it would also be called a miracle!

I can also sympathize completely. I apparently have a unique head shape and it has always been very difficult to find a helmet that fits perfectly.


From “H.S.” (December 2014): “Read every test for round heads. From Quantum II (discontinued, fragile visor) through the Vemar Geo (no spare parts in US, Motonation ceased support). What is your editor’s round head wearing or recommend for a street bike helmet? Didn’t know if your chart is up to date. Modular or full face with internal visor preferred. There is an eBay seller offering a new Vemar Geo for $150 shipped, but the lack of cheek pads, liners, visors, etc. is a big issue for me.

Editor’s Reply: The chart is always kept up to date, the problem is there have been almost no “Round” helmets released in quite some time. Most of the manufacturers, including Arai, have gone to a “Neutral” shape.

I always have problems because my head is wide at the temples. I’ve been wearing a SCHUBERTH SR1 (review) lately, which (surprisingly) fits pretty nicely, although it’s ridiculously expensive.

I’ve heard that the helmets sold in Japan for the Japanese market tend to fit “Round” heads, but not sure if that helps. You might be able to custom fit an Arai RX-Q by changing out cheek pads and/or liner.

If you find anything, let me know!


From “T.R.” (April 2013): “Man I can’t thank you guys enough, your helmet shapes article and information is awesome for a “long and narrow” who has struggled through the years to find a helmet that fits. I’ve been hanging on to dear life to my 2001 Arai Quantum F thinking I would never find another helmet that fit by silly oblong head! Now you’ve given me some options that I’m really excited about!”


From “D.A.” (April 2013): “Many thanks for your head shape information in your helmet reviews. I have sought out and purchased X-Lite X901, Shark RSI, and SCHUBERTH R1 and S1-Pro helmets based on this information. In the cases of the Schuberths, I have had these shipped over from Europe, sight unseen, and they fit my head shape perfectly. Thanks again, keep it up!”

  1. Hi,
    I am one of the thousands with helmet problems and have already wasted a lot of money and still looking for the ideal helmet.

    Is there a way to match your 7 categories – N to R – with a head measurement ratio. Mine, for instance measures W= 6.25″ and L = 7.75″ , a ratio of 7.75/6.25 = 1.24.

    Will this fall into SN category or N category.

    It will be very useful a head measurement to equates to a category – hopefully narrow down the searching

    1. Same here Chris. My head measures W=6.4″ and L=8.25″ for a ratio of 1.29. Circumference is 23 5/8″. Can’t find a helmet that fits right yet after months of searching. I wish someone would tie dimensions to Oval and Long Oval. I looked at multiple studies of head shape online and found that my ratio is nearly the exact average from the study. Then why are there so many neutral shaped helmets if I’m in the average?

    2. I believe this calculation is backwards. The CI is width divided by length times 100. So 6.25 / 7.75 x 100 = 80.6.

      CI 83 (female), 81.1 (male) is round

      I have the same questions, were do the ‘7 sizes’ WBW uses match the CI numbers?

  2. This page used to be a great resource but since it was updated it’s hard to read due to the background colors. There’s also no bold type to help one quickly find the different head shapes and the type of helmet your looking for, in short… this page was ruined by the update.

  3. I wonder if the author is reading the comments. Still useful….. but still not sure of the shape categories – possibly a head drawing for each category could help…..

  4. @Nick – Thanks for the quick response Nick. The visual is great help but you have 7 Shape Designations :- NA = Narrow; MN = Medium Narrow; SN = Slightly Narrow; N = Neutral; SR = Slightly Round; MR = Medium Round; R = Round.

    There are only 3 head shapes Long Oval, Round Oval and Intermediate Oval.

    Q1. In which Head Shapes do the different Head Designations sit?

    Q2. What is the difference between SN & SR.

    In my case my head measures W= 6.25″ and L = 7.75″ which definitely is not Round but would you say is N, SN or SR.

    One thing for sure I am not a Shoei Neotec – I have one and is not comfortable – I had to remove polystyrene to fit the Sena speakers and fit some foam on the sides to make it a bit narrow – an expensive mistake.

    I hope you can see my problem and I hope you can help.

    Your website has become the reference website for us bikers. A great achievement – well done!

  5. The latest changes to this page seem to help. It would be a great help if your 7 head shapes were converted to the 3 main ones that sites like Revzilla list. Also, I know it would be a pain but if these helmets were listed alphabetically by manufacturer in their respective categories they would be much easier to find for research needs.

  6. So what do you do when NO ONE in Nashville has any long oval helmets? They don’t even know what you’re talking about! I guess we have to go to every store and try every helmet on on the off chance one is ACCIDENTALLY long oval. Stupid thing to have to do when they can just standardize their measurements. Also, I came here to decide which head I have in the 7-item scale spoken of on your website. I found a bell curve and a vague “subjective” comment. Thanks for nothing. I guess I’ll just spend oodles in gas going to every dealer in 150 miles, or sell my bike.

  7. Will you looking at the new Shoei Neotec 2 ? I will be interested to know whether is a different shape from the old Shoei Neotec and in which way ie narrower or rounder than the old one.

    I tried one and it felt different but that could be down to so many people trying it on previously.

    1. Yes, we received a Neotec II to review on Monday. Review ETA 4-6 weeks!

  8. What to do if you have a large head, like size 8 standard ball hat size head and the big superstore near Columbus Oh has no idea on how to help you, except to say, whatever fits you best, just try on a few.

  9. Hello Martel.
    I got to learn so many newer information from your helmet review. Thanks for sharing such a fantastic article.
