Motorcycle Helmet Buying Guide: How to Choose the Right Helmet

Choosing a motorcycle helmet involves more than finding a design that matches your bike. The right helmet needs to suit your type of riding, fit your head correctly, use a secure fastening system, and meet the requirements that apply where you ride. This motorcycle helmet buying guide explains the main factors to check before buying so you can compare helmets based on useful information rather than appearance alone.

If you are comparing different types of helmets, you may also want to start with our complete helmet buying guide. It covers the basic principles of helmet sizing, fit, care, safety information, and replacement for different riding activities.

1. Start With the Type of Motorcycle Riding You Do

Your riding style is one of the first things to consider. A rider who spends most of the week commuting through city traffic may have different preferences from someone who rides long distances on highways or uses an off-road motorcycle.

Before choosing a helmet, think about where you normally ride, how long your trips are, the weather in your area, and how much face coverage you prefer.

Common motorcycle helmet styles include:

• Full-face helmets
• Modular helmets
• Open-face helmets
• Off-road helmets
• Dual-sport helmets

Each design has different characteristics. Understanding these differences makes it easier to narrow your options before you start comparing individual products.

2. Full-Face Motorcycle Helmets

A full-face helmet covers the top, sides, and back of the rider's head while also including a fixed chin section. Most models include a face shield that can be raised or lowered.

Full-face helmets are commonly used for street riding, commuting, touring, and sport riding. Depending on the model, features may include adjustable ventilation, removable interior padding, replaceable face shields, breath deflectors, and communication-system compatibility.

When comparing full-face helmets, check the actual specifications of each product. Do not assume that every model includes a sun visor, anti-fog insert, removable liner, or communication system just because another helmet with a similar appearance has those features.

If you are deciding between more and less facial coverage, read our upcoming full-face vs open-face helmet guide.

3. Modular Motorcycle Helmets

A modular helmet usually looks similar to a full-face helmet but includes a hinged chin section that can be raised on compatible models. This design can be convenient for riders who frequently stop during touring or commuting.

However, modular helmets vary considerably in design. Some models have specific instructions regarding whether the helmet can be used while the chin section is raised. Always follow the manufacturer's instructions for the exact model you own.

When shopping for a modular helmet, check the hinge mechanism, locking system, helmet weight, visor operation, ventilation, and stated certifications or standards.

4. Open-Face Motorcycle Helmets

Open-face helmets cover much of the head but do not have the fixed chin section found on a full-face design. Depending on the model, they may include a visor, face shield, or neither.

Some riders choose open-face helmets because they prefer greater airflow and an open field around the face. The trade-off is that more of the face remains exposed compared with a full-face design.

Choose according to the type of riding you do and the level of coverage you want rather than selecting a helmet purely because of its style.

5. Check the Applicable Motorcycle Helmet Safety Standard

Safety labeling is an important part of any motorcycle helmet buying decision. Requirements differ between countries, so you should check which standards apply where you ride and whether the specific helmet you are considering is labeled accordingly.

For motorcycle helmets intended for road use in the United States, Federal Motor Vehicle Safety Standard No. 218 is the relevant federal motorcycle helmet standard. Compliant helmets carry the required DOT certification labeling from the manufacturer.

It is more accurate to describe these helmets as meeting or being certified by the manufacturer to meet the applicable DOT requirements rather than saying that the government individually approves each helmet.

Do not rely only on a product photo showing a label. Review the product description, manufacturer information, model details, and labeling provided with the helmet. You can learn more in our helmet safety standards guide.

6. Measure Your Head Before Ordering

Motorcycle helmet sizing usually begins with head circumference. You should measure your head even if you already own another helmet because sizing can differ between manufacturers and models.

Use a flexible measuring tape and wrap it around the widest part of your head. The tape will normally run above your eyebrows, above your ears, and around the widest part at the back of your head. Keep it level and snug without pulling it tightly.

Record the measurement in centimeters and compare it with the manufacturer's size chart for the exact helmet you plan to purchase.

For more detailed measuring instructions, see our how to measure your head for a helmet guide.

7. Understand Motorcycle Helmet Head Shapes

Head circumference is not the only part of helmet fit. Two riders can have the same measurement but find the same helmet fits very differently because their head shapes are not identical.

Motorcycle helmet shapes are often described using terms such as round, intermediate oval, or long oval. These descriptions refer to the general relationship between the length and width of the internal helmet shape.

If a helmet creates a strong pressure point on the forehead, temples, or sides of the head, the issue may be the internal shape rather than simply the numerical size.

This is why it is useful to check both the manufacturer's size chart and any head-shape information provided for the model.

8. How Should a Motorcycle Helmet Fit?

A motorcycle helmet should fit securely around your head without excessive movement. It should feel evenly snug rather than loose in some areas and painfully tight in others.

When trying a helmet, check whether it moves independently when you gently turn or move it with your hands. Excessive movement can suggest that the helmet is too large or that the internal shape does not suit your head.

At the same time, severe pressure, numbness, or sharp discomfort may indicate that the helmet is too small or the wrong shape.

New helmet padding may feel firm, so do not judge fit only by whether the helmet feels extremely soft when first worn. Follow the manufacturer's fitting instructions and size recommendations.

Our how should a helmet fit guide explains fitting checks in more detail.

9. Check the Chin Strap and Fastening System

The fastening system is an important part of keeping the helmet positioned correctly during use. Motorcycle helmets can use different types of retention systems depending on the model and manufacturer.

Check that the strap can be adjusted properly and that you understand how its buckle or fastening mechanism works. The helmet should be secured according to the manufacturer's instructions every time it is worn.

Do not ride with the chin strap left unfastened simply because the helmet feels tight enough without it.

10. Consider Helmet Ventilation

Ventilation can make a noticeable difference during warm-weather riding or longer journeys. Motorcycle helmets may have intake vents around the chin, forehead, or top area together with exhaust ports toward the rear.

Some models allow you to open and close individual vents. This can be useful when riding through changing weather conditions.

However, the number of visible vents does not tell you everything about airflow. Internal channels, padding, visor position, riding speed, and overall helmet construction can all affect ventilation.

For more information, read our helmet ventilation guide.

11. Compare Motorcycle Helmet Visors

The face shield or visor affects visibility, airflow, and riding comfort. Check what is included with the specific helmet rather than assuming accessories shown in promotional photos are supplied as standard.

Depending on the helmet, visor-related features may include:

• Clear face shields
• Tinted replacement shields
• Internal sun visors
• Anti-fog insert compatibility
• Quick-release visor mechanisms
• Different visor opening positions

If you regularly ride at night, in rain, or in changing light conditions, consider how the visor setup will work in those situations.

See our motorcycle helmet visor guide for a closer look at visor types and maintenance.

12. Look at the Interior Liner and Padding

The interior affects both fit and day-to-day comfort. Many motorcycle helmets use removable cheek pads and liners, although this depends on the model.

Removable and washable components can make routine care easier, particularly if you ride frequently or in hot conditions. Check the manufacturer's instructions before removing or washing any helmet component.

Also look at the shape and thickness of cheek pads. They should contribute to a stable fit without creating severe discomfort.

13. Consider Helmet Weight

Helmet weight can affect comfort during longer rides. However, comparing weight alone can be misleading because helmet size, shell construction, features, visor mechanisms, and modular components can all affect the final figure.

A lighter number on a specification sheet does not automatically mean that helmet will feel better on your head. Balance and fit also matter.

If manufacturers provide helmet weights, compare models in similar sizes and categories for a more useful comparison.

14. Check Communication System Compatibility

Some riders use motorcycle intercoms for navigation prompts, rider-to-rider communication, or phone connectivity. If this matters to you, check whether the helmet has speaker recesses or is compatible with the communication system you intend to use.

Do not assume that a Bluetooth or communication unit is included unless the product listing specifically states that it is part of the package.

15. Do Not Choose a Motorcycle Helmet Based Only on Price

Motorcycle helmets are available across a wide range of prices. Cost can reflect differences in materials, finish, visor systems, ventilation controls, interior components, accessories, branding, and construction.

However, price alone does not tell you whether a helmet fits your head correctly or is suitable for your riding.

Start by checking the appropriate standard, correct size, head shape, secure fit, and intended use. After that, compare comfort features and your budget.

16. Be Careful When Buying a Used Motorcycle Helmet

A used helmet may have a history that is difficult to verify. You may not know whether it has experienced an impact, been stored in unsuitable conditions, or had components modified or replaced.

If you cannot confirm the helmet's history and condition, buying a new helmet from a seller that provides clear product information can make it easier to understand exactly what you are getting.

17. Know When to Replace Your Motorcycle Helmet

A motorcycle helmet does not remain usable indefinitely under every condition. Impact history, damaged components, material condition, storage, and manufacturer recommendations can all affect whether a helmet should continue to be used.

If a helmet has experienced a significant impact, follow the manufacturer's replacement instructions even if obvious exterior damage is not visible.

You should also check for damaged straps, cracked components, loose parts, deteriorated padding, or problems with the fastening system.

18. Check Exactly What Comes With the Helmet

Before completing your purchase, review the product listing carefully. Confirm the helmet size, color, visor type, included accessories, replacement parts, and other specifications.

A product photo may sometimes show accessories for demonstration purposes. The written product details should clearly tell you what is actually included.

If a feature is important to your purchase, verify it rather than assuming it is standard.

Frequently Asked Questions About Motorcycle Helmets

How do I choose the correct motorcycle helmet size?

Measure the widest part of your head and compare the result with the manufacturer's size chart for the exact helmet model. Also consider head shape because helmets with the same listed size can fit differently.

Should a new motorcycle helmet feel tight?

A new helmet should generally feel securely snug, but it should not cause severe pain, numbness, or strong isolated pressure points. Follow the manufacturer's fit guidance for the specific model.

What does DOT mean on a motorcycle helmet?

For helmets intended for road use in the United States, DOT labeling relates to the manufacturer's certification that the helmet complies with the applicable Federal Motor Vehicle Safety Standard No. 218 requirements. Buyers should check the complete product labeling and manufacturer information rather than relying only on appearance.

Is a full-face helmet better than an open-face helmet?

The two designs provide different levels of coverage and different riding experiences. A full-face design covers the chin and more of the face area, while an open-face helmet leaves the face more exposed. Consider the coverage you want, the type of riding you do, fit, and applicable safety requirements.

How often should I replace my motorcycle helmet?

Follow the replacement guidance from the helmet manufacturer. Impact history, damage, condition, age, and material deterioration can all affect whether a helmet should continue to be used.

Final Motorcycle Helmet Buying Advice

A good motorcycle helmet buying decision starts with the correct type of helmet, applicable safety requirements, accurate head measurement, and proper fit. Features such as ventilation, removable liners, visors, communication compatibility, and helmet weight can then help you narrow your options.
