Reasons You Need the Best Dirt Bike Helmet

Dirt bike injuries are the worst. There is an increased risk of fall on anything, from mud to stones to trees and even downhills.

You should take protective gear-helmet, goggles, neck brace, chest protection, knee braces, and boots- seriously, whether you are a professional or a new dirt bike rider.

However, never compromise on the quality of the helmet or any other motocross gear. Here are reasons you should always wear a dirt bike helmet while off-roading.

Head and Brain Protection

Your dirt bike helmet protects the head and brain from injuries. These injuries can be so fatal they may lead to death.

The helmet also protects your face from debris, dirt, and mud while riding. This is the main reason dirt bike helmets have provisions for goggles.

Protection from Harsh Weather

The regular dirt bike rider is riding motocross bikes under different weather. The conditions may abstract vision, increasing the chances of an accident.

Using the right helmet helps keep your face warm in cold weather and dry in the rain. Further, the helmet also helps protect you from the harmful UV rays of the sun.

It’s The Law

Wearing a helmet while riding a bike is a legal requirement. Many states make it mandatory for riders to have protective gear.

Some places have laws that mandate helmet wearing for individuals under 21. In case of an accident, you are partially guilty if you didn’t have a helmet on.

Improved Visibility

Visibility during the day may not be an issue, but we can’t say the same for the night. Cliffs and trees reduce other dirt bikers’ visibility. So wearing a helmet increases the chances of being seen by others.

The best motocross helmets for visibility are those with built-in reflectors or are brightly colored. But you can always add a few reflective tape lines to your helmet.

Mounting a headlamp on the helmet also increases your visibility. The light makes others aware that you are behind or ahead of them.


The best dirt bike helmets come in different colors and have different prints on them. Your dirt bike helmet is an excellent way to show off your style. Plus, it offers other dirt bike riders a glimpse into your personality.

Sports lovers can choose colors that symbolize their favorite teams. Or, science enthusiasts can choose to have a chemical equation or element on their motocross helmets.

Overall, wearing a helmet does not mean you need to look out of place and unattractive.

Set an Example for Younger Riders

If you want your kids to wear helmets when riding bikes (not dirt bikes necessarily) show them how. Wear yours to serve as a model for the next generation of riders.

The Difference Between Motocross Helmets and Street Bike Helmets

You may have noticed that dirt bike helmets look quite different compared to street and traditional bike helmets. The right type of helmet for your riding style is essential, so it is worth looking at the differences.


Dirt bike helmets have an extended chin while street bike helmets have a chin guard that is close to the face. The extended chin helps improve airflow compared to the chin guard.

You are often not riding your dirt bike as fast as a street bike. The low speed means you get hot fast and breathing can be difficult when you have the wrong helmet on. An extended chin ensures improved airflow while keeping you cool.

Street bike helmets feature an aerodynamic design, while their dirt bike cousins are bulkier and less aerodynamic. Of course, top speeds are not important while riding a dirt bike.

Sound Dampening

A street bike helmet will usually cover your ears because you are riding at higher speeds and for longer. However, the sound is not such a big concern when riding a dirt bike.

Some riders prefer hearing the engine, so they know what’s going on with the bike at all times. Wearing a dirt bike helmet can be uncomfortable because of the deafening road noise.

Impact Protection

Dirt and street bike helmets offer superior protection in case of an impact. But helmets for street bikes offer slightly better protection because of higher speeds.


Your dirt bike helmet has a large visor for blocking the sun from getting in your eyes. Off-road riding can be dangerous, so you need to concentrate and have good reflexes without worrying about the sun’s glare.

The visor also helps prevent debris and dust from reaching your eyes. This is especially critical when riding behind another rider.


There is some weight difference between dirt and street bike helmets, but negligible. Regardless of the type, manufacturers are trying to make each helmet as light as possible.

A lighter helmet makes it easy to go over jumps or bumps on a trail because your head is not moving around so much. Heavy helmets make riders tire sooner as it requires more effort to keep the head straight.

How Do I Choose a New Dirt Bike Helmet?

There’s a lot to consider when buying a new dirt bike helmet. Some helmets are fantastic for some people while others are not a good fit for other riders.

Think about these factors to decide which dirt bike helmet is best for you.

What Will the Helmet be Used For?

For a beginner, a high-priced and high-end first helmet with lots of features might not be the best buy. Choose a helmet that is comfortable, safe, and that you like wearing. Some basics you should look for include lightweight construction, good ventilation, and certified safety equipment ratings.

Replacing a well-used or damaged helmet is critical. Further, consider upgrading your choice if dirt bike riding is now more than a hobby.

Shell Material

The helmet’s material influences several factors, including comfort, weight, cost, and safety rating. The most common helmet shell materials are:

  • Polycarbonate-Flexes when absorbing energy and is the least expensive material.
  • Fiberglass composite-A flexible material that will crush and split as it absorbs impact energy, slightly more expensive.
  • Carbon fiber shell-These helmets distribute impact energy. They are the lightest and most expensive shell materials. 
  • EPS-The foam material is compressed into the inside of a helmet. It helps absorb shock from impacts. 

Helmet Weight

The typical weight range for the best dirt bike helmets is from 1400 to 1800 grams.

A heavy helmet leads to a poor dirt bike riding posture and causes a sore neck. Heavy helmets get hot to ride in, leading to an uncomfortable, sweaty riding experience.

I recommend you stay within the 1600 grams range or below. However, you may come across one that weighs slightly more, and with all the specifications below, go for it. But 1600 grams is an excellent starting point.

Helmet Size and Head Shape

A proper helmet fit plays a critical role in the outcome of an accident. Your head size is a big determinant of the right dirt bike helmet for you.

Find your head size with these steps:

  1. Use a soft measuring tape to measure your head a half-inch above the eyebrows, over the ears, and to the back of the head at the largest point.
  2. Compare head size to specific motorcycle helmet manufacturer size charts for a match.
  3. A perfectly sized helmet should sit squarely on the head with the eye-port just above your eyebrows. A new properly fitted helmet will fit snug at first and loosen as it is broken in.
  4. If your fingers can fit between the helmet and your head easily or if the helmet is moving, consider getting a smaller size.

Another major consideration is the shape of your head. Some manufacturers will account for these head shapes:

  • Round oval-A head that is longer side to side.
  • Intermediate oval-A short front to back and wide side to side. Manufacturers of most helmets offer intermediate oval motocross helmets.
  • Long oval-Long front to back and narrow side-to-side

Will Customization Improve Helmet Fit?

You can never be certain of a perfect fit along the jawline even with the right head size and shape measurement. A good option is to consider customization of the helmet.

The best dirt bike helmet will come with removable padding that allows for customization. This added feature lets you make the most out of the unit’s safety features.


Good ventilation lets you ride better. The helmet also feels lighter while providing the recommended level of safety.

Air vents in the helmet help cool you off. Lack of or poor ventilation can make you sweaty and hot, which reduces your stamina and may cause you to become confused while riding.

Advanced Safety Technology

Some technologies are proprietary to a manufacturer, and others are industry standards. Make sure that each safety technology is DOT approved.

Cheaper helmets may not have advanced technologies. Instead, they use the shell’s construction and internal padding as the protection mechanism.

More expensive dirt bike helmets will have these technologies.

Multi-directional Impact Protection Systems (MIPS)

MIPS is an industry-standard. The technology has two layers inside a motorcycle helmet that slip past each other. This allows your head to rotate slightly in the helmet during a motocross crash, reducing rotation forces reaching the brain.

Magnetic Visor Release System (MVRS)

A Fox Racing technology that helps manage rotational forces on impact. The visor is attached to the helmet using a magnet, so it detaches itself in a crash instead of exacerbating the situation by adding rotational forces.

Fluid Inside

The company, Fluid Inside, has developed a technology that mimics the cerebral spinal fluid inside pods. The strategically placed pods in a helmet absorb some impact. Fluid Inside has licensed helmet manufacturers to use their technology.

Emergency Cheek Pad Removal

This system allows easy cheek pads removal after a crash with much less movement of the rider’s head and less effort. Helmets either have a magnetic or clip system for removing the cheek pads.

Kinetic Polymer Alloy (KPA)

KPA is an LS2 proprietary helmet shell material that flexes on impact. While most shells are rigid, a KPA shell moves a bit to absorb some of the energy.

360 Turbine

This Leatt technology features a series of small circular turbines that deform to absorb impact. The material in turbines hardens instantly on impact to dissipate rotational energy and deflect impact energy.

Helmet Safety Ratings

Pay attention to the little sticker on this side of a helmet or box. The sticker contains information on the safety standards the helmet conforms to.

Each safety standard organization carries out rigid procedures on the helmet, including:

  • Making sure the helmet provides a minimum side vision of at least 105 degrees on both sides;
  • Chin straps remain fastened without stretching or breaking;
  • Minimum safety standards that ensure optimal impact protection.

The safety standards are:

  • DOT by the United States Department of Transportation
  • ECE 22.05 by the U.N. Economic Commission for Europe
  • Snell (M2020) a United States non-profit founded after the death of Peter Snell

How Much Does a Good Dirt Bike Helmet Cost?

Price is usually the first thing people look at. However, the price reflects the materials used and the features included.

Avoid cheap helmets to save some bucks by compromising on your safety. The recommended buying price for a good quality helmet ranges from $200 to $400. But pro-level dirt bike helmets can cost as much as $800.


This article is an excellent guide on what you should expect from the best dirt bike helmet. As previously mentioned, my preferred choice for the best dirt bike helmets is the Fly Racing Kinetic Thrive Helmet.
