The best motorcycle helmet for a long oval head is the Arai Signet-X, because Arai builds it on its dedicated Long Oval interior instead of padding out a standard shell. If you want to spend about $300 or less, the Icon Airflite is the other current road helmet whose maker openly calls it a long oval fit. Beyond those two, true long oval helmets are rare, so most riders end up choosing from a short list of retailer-rated long oval models or tuning an intermediate oval helmet.

This guide is research-based. We did not wear or crash-test these helmets. We pulled head-shape claims from manufacturer fit pages first, used retailer fit ratings only where the maker says nothing (and we say so when we do), and checked certifications and current US prices as of November 2026. Prices change often, so treat every number as “about.”
What “long oval” actually means
Look down at your head from above. Every head is longer front to back than it is side to side, but the ratio varies. Helmet makers group heads into three rough shapes:
- Round oval: length and width are fairly close. These riders often feel side pressure in most helmets.
- Intermediate oval: the middle of the bell curve. Arai says its intermediate shape is used in “most of our models,” and most Shoei, Bell, HJC, Klim and Schuberth road helmets sit here too.
- Long oval: noticeably longer front to back and narrower side to side. Icon describes its long oval fit as “long front-to-back and narrow side-to-side,” with extra forehead room for riders who get pressure points in other helmets.
The problem for long oval riders is simple. Most shells are built for the middle group. When your head is longer than the helmet’s interior, the helmet touches you at the front and back first. You can fix that by going up a size, but then the sides are loose, and a loose helmet can shift in a crash. That is why shape matters as much as size.
If you are not sure where you fall, our sister guide on the best motorcycle helmets for round heads covers the opposite problem, and the two together make it easier to see which camp you are in.
How to tell if you have a long oval head
You do not need special tools. Try one or more of these:
- The overhead photo. Wet or flatten your hair, have someone stand on a chair and photograph the top of your head from directly above. If the outline looks like a stretched egg rather than a near circle, you likely have a long oval head.
- The ratio check. Use a soft tape or two books held against your head to measure length (forehead to back) and width (side to side, just above the ears). As a rough rule of thumb, a length-to-width ratio clearly above what your friends measure points to long oval. There is no industry-standard cutoff, so use this as a hint, not a verdict.
- Your helmet history. This is the most reliable sign. If most helmets that fit your circumference leave a red line across your forehead and feel roomy at the cheeks and temples, you are probably long oval.
Shape is only half the job. You still need the right circumference measurement, taken about an inch above your eyebrows at the widest point. Our guide to sizing and buying a helmet walks through that step by step, and the helmet size calculator turns your number into a starting size.
Long oval fit warning signs
These are the classic signs that a helmet is too round for your head:
- Forehead “hot spot.” A sore line across the forehead after 15 to 30 minutes, often with a red mark when you take the helmet off. This is the number one complaint from long oval riders.
- Pressure at the back of the skull at the same time as the forehead pressure. Front and back contact with slack at the sides is the textbook shape mismatch.
- Gaps at the temples or sides. You can slide a finger in beside your temple easily, or the helmet rocks side to side when you shake your head.
- Headaches that start late in a ride. A helmet can feel fine in the store and become painful after an hour.
- Sizing up “fixes” the forehead but the helmet moves. If the bigger size stops the pain but rotates easily when you twist it, you have traded one problem for a safer-looking but worse one.
A good long oval fit feels snug and even all the way around, with firm cheek pressure and no single painful spot. Wear any new helmet for at least 30 minutes indoors before you remove tags or ride. New liners do break in, but pressure that hurts after half an hour rarely goes away.

|---|---|---|---|---|
| Arai Signet-X | Full face | Long oval (Arai) | DOT, Snell M2025 | $680 to $960 |
| Icon Airflite / Airflite MIPS | Full face, drop-down visor | Long oval (Icon) | DOT, ECE 22.06 | $250 to $330 |

“Retailer rating” means the manufacturer does not publish a head shape for that model, so we are relying on RevZilla’s head-shape listing. Those ratings are useful but less reliable than a maker’s own fit page. For what the safety labels mean, see our helmet safety ratings explainer.
The best motorcycle helmets for long oval heads
1. Arai Signet-X: best overall long oval helmet
Why it is here: Arai Americas states plainly that “the Signet-X has Arai’s LONG OVAL (LO) interior fit shape,” and its fit page names the Signet-X as the model with that interior. Most brands that sell to long oval riders do it with thinner pads. Arai builds a separate interior shape, which is why the Signet-X shows up at the top of nearly every long oval list.
Key details:
- Interior: Long Oval, per Arai’s fit guide
- Certifications: DOT and Snell M2025 on current US stock (older listings carry Snell M2020, so check the label)
- Five shell sizes covering XS to 2XL
- VAS shield system with a Pinlock-120 anti-fog insert in the box
- Adjustable top vents, removable ES chin cover for wind noise, anti-microbial liner
- Price: Arai lists solid colors from about $680 MSRP; frost finishes and graphics run about $790 to $960 at retailers
Who it fits best: Riders with a clearly long, narrow head who have given up on forehead pressure in other premium helmets. It suits street, sport touring and commuting more than full track use.
Trade-offs: It is expensive, and it has no internal sun visor. If you are only slightly long oval, the Signet-X can feel loose at the sides; Arai’s own fit guidance says to try the helmet on before buying. Arai also notes that its round oval Quantum-X can take a Signet-X or Corsair-X liner to become an intermediate oval, which tells you the Corsair-X uses the intermediate shape, not the long one.

2. Icon Airflite: best long oval helmet under $350
Why it is here: Icon is one of the few brands that markets a long oval shape on its own product page. Its Airflite page calls out a “LONG OVAL FIT” that is long front to back, narrow side to side, with extra forehead room. That is exactly the complaint long oval riders have, and it comes from the manufacturer, not a reviewer.
Key details:
- Interior: Long oval, per Icon
- Certifications: DOT FMVSS 218 and ECE 22.06, per Icon
- Internal DropShield sun visor that can be raised and lowered with gloves on
- MIPS rotational-impact liner on select graphics (Snack Attack, Blegh, Edo, Tiger’s Blood at the time of writing)
- Icon lists weights of about 1,610 g (XS-S), 1,690 g (M-L) and 1,730 g (XL-3XL)
- Polycarbonate shell; RevZilla lists three shell sizes and sizing up to 3XL
- Price: about $250 for the Airflite Dark, $299 for most graphics, $330 for MIPS versions
Who it fits best: Long oval street riders on a budget who want an internal sun visor and an ECE 22.06 label. It is also a good test helmet: if the Airflite feels right where everything else hurts your forehead, you have confirmed your shape for under $350.
Trade-offs: The aggressive styling with its fighter-jet chin is not for everyone, and polycarbonate shells tend to be bulkier than premium composites. Do not assume every Icon helmet shares this fit. Icon describes its Airframe Pro as intermediate oval, even though some retailers list it as long oval, and RevZilla lists the Icon Airform as intermediate oval as well.

3. Bell SRT Modular: best long oval modular
Why it is here: Long oval modulars are hard to find. RevZilla lists the Bell SRT Modular as a long oval fit, and it is one of the few flip-up helmets with that rating at a mid-range price. Be aware that Bell’s own SRT Modular page does not state a head shape, so this pick rests on a retailer rating plus owner feedback, not a factory spec.
Key details:
- Head shape: Long oval (RevZilla listing); Bell does not publish one
- Certifications: DOT and ECE, per Bell
- Fiberglass composite shell; RevZilla lists three shell sizes and XS to 3XL
- Bell lists a weight of about 1,750 g in size medium
- Flip-up Panovision shield, internal sun visor, recessed speaker pockets, eyewear channels in the liner
- Price: Bell lists about $301 to $550 depending on finish
Who it fits best: Touring riders, glasses wearers and commuters with a long head who want to flip the chin bar up at gas stops.
Trade-offs: At about 1,750 g it is on the heavier side, which is normal for a modular. Some SRT Modular listings are tagged as closeouts, so colors and sizes may be limited. Most other Bell street helmets, including the Qualifier, Eliminator, Broozer and MX-9 Adventure, are listed as intermediate oval, so do not treat Bell as a long oval brand overall. If it does not fit, an intermediate modular with thick cheek pad options is the fallback.

4. LS2 Subverter Evo: best long oval dirt helmet on a budget
Why it is here: Long oval riders who ride trails or dual sport bikes have even fewer choices. RevZilla lists the LS2 Subverter Evo as a long oval fit, and it carries both DOT and ECE 22.05 approval at about $200 to $250. LS2 does not publish a head shape for it in the listings we found, so treat the rating as a strong hint rather than a guarantee.
Key details:
- Head shape: Long oval (RevZilla listing)
- Certifications: DOT and ECE 22.05
- Polycarbonate shell in three shell sizes, XS to 3XL
- Listed with rotational-impact protection and a D-ring strap
- Price: about $200 to $250
Who it fits best: Off-road, enduro and dual sport riders who wear goggles and want a long oval fit without spending dirt-helmet premium money.
Trade-offs: It is a true dirt helmet, with no face shield and a big peak, so it is loud and drafty on the highway. Its ECE approval is the older 22.05 version, not 22.06.

5. Shoei RF-1400 with fit tuning: best for mild long ovals
Why it is here: The RF-1400 is not a long oval helmet. RevZilla lists it as intermediate oval, which is where most Shoei road helmets sit. It earns a spot because Shoei offers more fit adjustment than most brands. That makes it a realistic option for riders who are only slightly long and feel a mild forehead pinch in standard helmets.
Key details:
- Head shape: Intermediate oval (RevZilla listing)
- Certifications: DOT and Snell M2025
- Five shell sizes, XS to 3XL
- Shoei sells replacement cheek pads in several thicknesses (31, 35, 39 and 43 mm are commonly listed) and different center pads for the RF-1400
- Certified dealers offer the Shoei Personal Fitting System, which measures your head and adds shims to the center pad to relieve pressure points
- Price: about $550 for solids, up to about $750 for graphics
Who it fits best: Riders who are between intermediate and long oval, want a premium sport-street helmet, and can visit a Shoei fitting dealer.
Trade-offs: Tuning can soften a mild mismatch, but it cannot turn an intermediate shell into a long oval one. If your forehead hurts badly in an RF-1400, go straight to the Signet-X or Airflite.

6. AGV X3000: retro long oval pick, if you can find one
Why it is here: RevZilla lists AGV’s retro X3000, styled after Giacomo Agostini’s 1970s helmet, as long oval. It is one of the very few vintage-style full face helmets with that rating.
Key details:
- Head shape: Long oval (RevZilla listing)
- Sold in the US as a DOT version; check the label for ECE status, since the European version carries ECE 22.05
- Price: about $515 for graphics up to about $700 for replica designs
Who it fits best: Café racer and classic bike riders with long heads who want period looks.
Trade-offs: As of November 2026, RevZilla shows the X3000 graphics we checked as out of stock, and AGV’s US site points mostly to outlet stock. Expect limited sizes. It also lacks a dedicated rotational-impact liner, so we rank it last.
Helmets often called long oval that are not
A lot of “long oval” lists online repeat claims that the manufacturer or the main US retailer does not support. Before you buy any of these for a long head, check the fit info yourself:
- Icon Airframe Pro: Icon calls it intermediate oval, with a five-piece liner that offers 27 fit combinations.
- Fly Racing Revolt: RevZilla lists it as intermediate oval.
- Klim Krios Pro, Schuberth C5, Arai XD-5: all listed as intermediate oval.
- Bell Eliminator, Qualifier, Broozer: intermediate oval.
Intermediate helmets with plenty of pad options can still work for a slightly long head. They are just not built for one.
How to choose a long oval helmet
1. Start with shape, then size
Measure your circumference first so you know your starting size. Then filter for long oval. Trying a long oval helmet in your measured size usually works better than trying a round helmet one size up.
2. Trust manufacturer fit pages over lists
Arai and Icon publish head shapes on their own pages. Many brands do not. When a brand is silent, retailer ratings and owner feedback are the next best thing, but they can be wrong. Notice how often “long oval” lists include helmets that the maker itself calls intermediate.
3. Match the helmet to your riding
Long oval options shrink fast once you add requirements. If you need a modular, the Bell SRT Modular is one of the few choices. If you ride dirt, the LS2 Subverter Evo is one. For general street use, you have the most choice: Signet-X at the top, Airflite on a budget.
4. Check the safety label, not just the shape
Every helmet here carries DOT. ECE 22.06 is the newest European standard and includes extra tests, including rotational impact. Snell M2025 focuses on higher-energy impacts. A perfectly shaped helmet still has to meet a standard you trust, so look at the sticker inside the helmet before you buy.
5. Do a 30-minute wear test
Wear the helmet indoors, tags on, for half an hour. Watch for forehead hot spots, rear pressure, and side gaps. Shake your head and push the helmet up and down by the chin bar; your skin should move with it. Keep the box and receipt until you are sure.
6. Buy where returns are easy
With so few long oval models, you may need to try two or three before one fits. Retailers with free exchanges on unworn helmets are worth the small price difference.
Padding tweaks that help long oval riders
If a helmet is close but not perfect, a few adjustments can make it workable. Stick to the maker’s own parts. Never cut, carve or compress the EPS foam liner, because that is the part that protects your head.
- Thicker cheek pads. Long oval riders often end up with loose sides once the forehead fits. Many brands, Shoei among them, sell cheek pads in several thicknesses. Going thicker at the cheeks can firm up the fit without moving to a smaller, more painful size.
- Thinner or different center pad. A thinner crown pad lets the helmet sit slightly lower and can shift contact away from the forehead. Shoei’s fitting system goes further by adding shims to the center pad in specific spots.
- Peel-away foam layers. Some premium helmets have removable foam layers in the cheek or temple pads. Check your owner’s manual to see if yours does and where they are.
- Brow pad adjustments. On some helmets the front of the comfort liner is a separate piece. A thinner version, where the maker offers one, can ease forehead pressure.
- Give it a few rides, not a few months. New cheek pads usually compress a little in the first several hours. Forehead pain from a shell that is too round does not usually go away with time.
If you have tried thicker cheek pads and a different center pad and the forehead still hurts, the helmet’s shape is wrong for you. Move to a true long oval model instead of forcing it.
FAQ
Which helmet brands make long oval helmets?
Among current road helmets, Arai (Signet-X) and Icon (Airflite) are the clearest examples, because both makers publish the long oval fit themselves. Retailers also list the Bell SRT Modular, LS2 Subverter Evo and AGV X3000 as long oval. Most other models from Shoei, Bell, HJC, Klim, Schuberth and AGV are intermediate oval.
Is the Shoei RF-1400 good for a long oval head?
It is listed as intermediate oval, so it is not built for a long head. Riders who are only slightly long sometimes make it work with different cheek pads or Shoei’s Personal Fitting System at a certified dealer. If you have strong forehead pressure, a dedicated long oval helmet is a better bet.
Can I just buy a bigger helmet for my long oval head?
Not safely. Sizing up may stop the forehead pain, but it usually leaves gaps at the sides, and a helmet that moves on your head can shift or roll off in a crash. Pick a long oval shape in your correct size instead.
What is the cheapest long oval motorcycle helmet?
For street riding, the Icon Airflite Dark at about $250 is the least expensive current helmet we found with a manufacturer-stated long oval fit. For dirt riding, the LS2 Subverter Evo at about $200 to $250 is retailer-rated long oval.
Is the Arai Signet-X the only long oval Arai?
In Arai’s current US lineup, yes. Arai’s fit guide names the Signet-X as its Long Oval model and the Quantum-X as its Round Oval model, and says most other Arai models use the Intermediate Oval shape. Older Arai helmets like the Signet-Q were also long oval, but they are no longer current.
Do long oval helmets fit women differently?
Head shape is not tied to gender, so the same shape advice applies. Women with smaller heads should check that the long oval model comes in a small enough shell. The Signet-X starts at XS, and the Icon Airflite starts at XS as well.
