Background

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

Over the past 10 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. See our 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. *The AGV Ti-Tech XXL size is equivalent to a size large in other helmets, in our opinion.  
  2. The Vemar VSREV has a different internal shape than any other helmet; we're calling it the "Round Oval"; see the review for more details.
  3. Unconfirmed and possibly not correct.
  4. Actual recorded weights using Polder electronic scale, claimed accurate to 1 g or 0.125 oz.

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!"
