Best Motorcycle Helmet for Small Head: Top Picks Compared

For a small head, the Shoei RF-1400 is the premium full-face most often named because it uses four shell sizes, so an XS is built on a smaller shell rather than just padded out; the HJC i10 or RPHA 11 Pro covers budget and mid-range buyers; the AGV K6 suits narrower heads; and Arai suits riders with rounder heads who want the most shell-size options. Whatever you choose, measure your head first and confirm that the maker’s XS actually uses a smaller shell.

Why shell sizes matter more than the size label

A helmet is a hard shell, an energy-absorbing liner, and comfort padding. In many ranges, a small helmet is simply the same shell with thicker padding. That tends to look oversized, to feel top-heavy, and to catch more wind. Brands that cut several shell sizes, giving the smallest sizes a smaller shell and liner, usually fit small heads more closely. Reviewers often point to the Shoei RF-1400 as a good example, with four shell sizes across XS to XXL.

Weight and neck fatigue also come into play. A lighter helmet is easier to hold up at highway speeds, and smaller riders feel the difference sooner.

At a glance: helmets with XS sizing

Specifications come from the makers and from review round-ups such as Revv Rider, Windburned Eyes, and Infinity Motorcycles. Sources sometimes disagree, for example on the number of shells for the Bell Race Star, so check the maker’s own page.

Shoei RF-1400

One review calls this the top premium pick for small heads. Having four shell sizes means the XS looks and feels proportionate. It carries Snell M2020 and DOT listings per the same source. Expect a break-in period, and note that XS graphics selection is more limited.

AGV K6

The K6 is a lighter carbon-aramid construction at around 1,350 grams in XS according to one review, with four shell sizes and ECE 22.06 homologation. It runs slightly narrow, so it can suit a small, narrow head, but riders with a rounder head may find it tight at the temples.

HJC RPHA 11 Pro and i10

The RPHA 11 Pro is the mid-range option, reported at about 1,400 grams in XS with DOT and ECE ratings. Reviewers say it is noisier than premium helmets at highway speeds, and the cheek pads may need breaking in. The i10 is named as the budget full-face. HJC sizes run XS to 5XL on one size chart, with XS starting at 53 centimeters.

Arai

Arai is known for its hand-built helmets and variety of shell sizes, with up to six across the range. The Regent-X uses the Intermediate Oval fit and is offered in XS. One outlet says Arai sizing starts at 3XS for 49 to 50 centimeter heads. Most size charts from retailers list Arai, Bell, and Shoei at XS through 3XL for 53 to 66 centimeters, so treat the very small sizes as special order and confirm with the maker. The Corsair-X is at the top of the price range and is heavier, at around 1,550 grams in XS in one review.

Other options

The Bell Race Star Flex DLX is for track-focused riders, while the Bell Custom 500 is the cruiser open-face choice with five shell sizes. The Scorpion EXO-R1 Air has an inflation system to tune fit. The Shark Evo-One 2 and LS2 Challenger GT suit riders who want modular or touring features. Heavier helmets are harder on a small rider’s neck on long rides.

Head shape and fit

• Know your shape. Most HJC, Shoei, and Bell helmets are described as using a similar common shape, and Arai’s fit differs. Shapes are usually described as round, intermediate oval, or long oval.
• Measure correctly. Wrap a soft tape around the widest part of the head, about one inch above the eyebrows and around the back.
• Snug is right. The cheeks should be pressed gently and the helmet should rotate your skin, not slide over it, when you move it side to side.
• Wear it for ten minutes. Hot spots at the forehead or temples appear fast. A headache is a sign to try another shape.
• Glasses. Check that your frames slide in and out without painful pressure.

Safety and care

Certification marks vary: DOT in the United States, ECE 22.06 in Europe, and optional Snell. Buy the one that applies where you ride and read the manual. Replace a helmet after any significant impact, and after the maker’s recommended age. Wash the pads with mild soap, and avoid solvents or stickers that could damage the shell. For ongoing headaches or neck pain, speak to a doctor.

Pick X if…

Budget tiers in plain terms

Budget helmets, such as the LS2 and the HJC i10, give certified protection but usually fewer shell sizes. Mid-range options such as the HJC RPHA 11 Pro and Scorpion EXO-R1 Air add better ventilation and fit features. Premium helmets from Shoei, AGV, Bell, and Arai spend the extra on shells that are scaled to size, lighter materials, and refined noise control.

Alternatives to consider

• Youth helmets. Not designed for adults and often lack adult road certification, so confirm the label.
• Modular helmets. Convenient, but heavier, and a heavy helmet tires small riders sooner.
• Try-on at a dealer. Several brands side by side often reveals the shape that works.

Noise, ventilation, and long rides

Small riders often sit lower behind the windscreen, which changes how wind hits the helmet. Reviewers describe the HJC RPHA 11 Pro and Scorpion EXO-R1 Air as noisier than premium rivals, while premium shells from Shoei and Arai are generally described as quieter, though sources do not publish a common decibel test. Earplugs designed for riding are a sensible addition with any helmet. Ventilation also varies: the RPHA 11 Pro and RF-1400 are praised for airflow, and heavier touring helmets add features but also weight. Think about your typical ride, whether short commutes or long highway days, and weigh weight and noise accordingly.

Frequently Asked Questions

What size motorcycle helmet fits a small head?

Many brands list XS for roughly 53 to 54 centimeters. Some, such as Arai, reportedly go smaller by special order. Measure your head and compare with the maker’s chart.

Why does my XS helmet look too big?

Some makers use the same shell for several sizes and vary only the padding. Look for brands with multiple shell sizes, such as Shoei with four.

Which helmet is lightest for small riders?

One review lists the AGV K6 at about 1,350 grams in XS. Weights vary by size and by source.

Is a heavier helmet worse?

It can tire the neck on long rides, particularly for a smaller rider. Weight matters, but a correct fit matters more.

Should I buy a helmet online?

You can, if the retailer allows returns and you know your head shape. Trying several brands in a store is usually quicker.

When should I replace my helmet?

After any significant impact, and by the age limit in the maker’s manual. A damaged shell, loose liner, or frayed strap is also a reason to replace it.
