Buying Guide:

Safety Ratings:

Several helmet safety standards currently exist. Each one offers a different safety testing and level of protection. Your helmet must, first and foremost, provide the correct and suitable safety rating for the type of riding you’ll be doing.

DOT (Department of Transport) is an American certification required for all helmets sold in the USA to carry this standard. DOT certification means that a helmet has been manufactured to a set standard.

ECE (Economic Commission for Europe) certification is more rigorous than DOT ratings. The ECE tests impact absorption and rotational forces on certain parts of dirt bike helmets to ensure they provide a necessary level of protection. This certification is recognized by more than 50 countries.

Snell certifications are regarded as the highest current safety rating available, as they’re designed for motorcycle and motocross racing standards.

Fit and Comfort:

All the safety measures and development mean nothing if the helmet doesn’t fit properly. Ensure that a comfortable fit is found: the helmet must not move on your head when you nod or turn your head. If the helmet moves, set the chin strap tighter. The best MX helmets under $300 feature helmet liners and padding. These are adjustable and removable so that you can add more padding or remove padding accordingly for the best fit.

Those same cheek pads and liners can be swapped a size up or a size down for a more comfortable fit. When you’re zigzagging on dirt trails or jumping over tabletops, you’ll undoubtedly be gasping big mouthfuls of air as the adrenaline pumps through your body. You need as much ventilation coming through your chin bar and into your mouth and lungs. If your cheek pads are too tight, it will feel like you’re overheating and not getting enough air into your lungs. Our review of the best dirt bike helmets under $200 goes into more detail about comfort.


The helmet’s internal pads and liners must be made of moisture-wicking fabrics that are easy to remove and washable. These are mostly made from polyester fabrics that offer anti-bacterial fibres.

The helmet’s shells are usually made of lightweight polycarbonate, fiber glass or carbon fiber layers. The lightest helmets are constructed from polycarbonate and carbon fiber. They offer increased strength and energy absorption in the event of a crash. Under the $300 budget cap, the best helmets feature polycarbonate shells with state-of-the-art manufacturing technology.

Vision and Goggles:

A clear view is crucial for dirt bike riding. It is not a stylistic element for designers to create wide fields of view for dirt bike helmets: it allows a rider the best peripheral vision for safer riding. You’ll be using goggles with your helmet and the closer these fit to your face, the less of a disturbance they will be in your vision. Through dust, bushes, riding near other riders in a motocross race, to having the sun in your eyes and stones flying at your head, you want to be able to see everything around you to keep track of the obstacles in your field of vision.

When you try on helmets, bring along your goggles so that you can see how they’ll fit with you helmet and work with enhancing your vision.

Read how the best dirt bike helmets can improve your field of vision.


When you’re on the footpegs and breathing hard, every muscle in your body is alive and burning. The weight of your helmet might not seem like a big deal when you’re trying it on, but after 10 minutes jumping your dirt bike, you’ll know all about it from the spasms in your neck and shoulders. While the helmet need not way more than 5 lbs, try to find one that’s as close to 3.5 lbs as you can for the best weight/safety ratio.


A distinguishing factor of dirt bike helmets are their peaks. These are adjustable for you to find the best view forward, while providing you protection from flying debris, mud, sand, and keeping the sun away from your eyes.


Good ventilation can make your helmet feel lighter than it actually is. The air vents keep your head cool with large slots up front to suck air into the chin bar. There are usually two areas with rear exhaust vents for the warm air to circulate out of the helmet, too.
