Best Motorcycle Helmets for Big Heads [2024 UPDATE]

If you’re looking for the best motorcycle helmets for big heads, then right here is where you will find either the right helmet for you or a good lead to find that helmet elsewhere.

We are confident that you will find the right extra large motorcycle helmet in the style you prefer from a brand that you feel comfortable with, and with proper DOT FMVSS-218 certification.

You see, the problem with helmet manufacturers is that they prefer to produce helmets they know they can sell, like Joe Average’s head size. It’s the same problem for all types of helmets. Now, let’s take a look at some helmets.

Large Size Motorcycle Helmets

There are a few things you need to consider before deciding which helmet you want to buy. Of course, there’s always the price that should be within your budget, but there’s more to it than buying a 4XL motorcycle helmet just because your friend’s 4XL helmet fits perfectly.

Measure Your Head

Measuring your head size isn’t rocket science and can be done quite easily by yourself with a tape measure or a piece of string and a ruler.

Fortunately, most motorcycle helmet manufacturers follow the same sizing, so that a 3XL HJC is the same measurement as an XXXL Scorpion. However, Daytona differs very slightly as you can see in the charts below.

Even if your current motorcycle helmet has expired and you know the helmet size, it’s always a good idea to measure your head each time you plan to purchase a new helmet. Just to be sure!

The point is that you need to be absolutely sure of your head size, as well as the sizing used by the manufacturer of your intended helmet purchase.

Find Your Head Shape

Starting out with the right size helmet is just the first step to a perfect fit, the second step is knowing your head shape. To find your head shape, you will probably find it easier if someone were to look down at your head from above.

Intermediate Oval shape is the most common, and as a result it will be the shape that most helmets come in. If your head shape is Long Oval then you will find that the Intermediate Oval doesn’t feel right and you will probably be better off looking for a helmet to suit your head shape.

6XL Motorcycle Helmets

And now for the bad news. Vega used to have a 6XL motorcycle helmet that went by the name of Ultra Big Head, but it is no longer available. The last time I checked, it was not even mentioned on their website, so possibly it is no more.

If a 6XL helmet becomes available in the future, we will put it right here. In the meantime, if you need a helmet larger than the 5XL, you could possibly contact HJC and ask if they can do a custom job for you.

Availability Of Large Size Motorcycle Helmets

As the helmet size increases, the range of brands and the availability of sizes decreases. 5X-Large motorcycle helmets are usually available but sometimes you may need to come back a few days later due to lack of stock or supply-chain issues. Just keep trying!

Right Size and Fit

If your helmet does not fit correctly, then it can’t protect you properly which is why you bought it in the first place. If your helmet is too small / too tight it will be extremely uncomfortable, can give you a headache, and make you tired. That’s the last thing you need while out riding.

It is true that the cheek pads of a new helmet should be pushing against your cheeks, but if your helmet is pinching and leaving red marks, then it is too small.

If your helmet is too big / too loose, then you stand the chance that in a fall your helmet may slip off your head completely, or shift sufficiently that it doesn’t offer protection where it should.

New helmets should fit snugly and comfortably. After about 20 hours of wearing the helmet, the break-in period, the liner will have compressed slightly to conform to your head shape.

Motorcycle Helmet Certification

When buying a motorcycle helmet anywhere, you need to be sure that it has the necessary certification for where you will be riding.

All of the helmets we have listed have DOT FMVSS-218 certification. Some have both DOT and ECE certification, and some of the 3XL helmets may have Snell certification, though for whatever reason manufacturers don’t usually submit larger sized helmets for Snell testing and certification.

Proper certification is necessary for legal reasons, plus it can give you some reassurance that the helmet has been tested and approved for road use.

When buying a helmet beware of fake helmets, which may even have fake certifications. They may look real and be a bargain-basement price, but they won’t protect your head when you need it most.

The rule of thumb here is that if the price sounds too good to be true, then it’s better to avoid it for the sake of keeping your head in one piece.

I’m sure you will find a large motorcycle helmet to suit your needs.
