The Lightweight Motorcycle Helmet Guide for 2024

January 3, 2024
By Michael Padway


In 1914, a British physician, tired of seeing motorcycle head injuries every two weeks, came up with the first motorcycle helmet. Made of little more than stiff canvas covered in shellac, it still managed to do its job and saved a rider from a severe head injury in the 1914 Isle of Man race.

Today, modern helmets are considerably more sophisticated thanks to over a century of evolution and refinement. However, they are also much more substantial, with full-face helmets weighing up to 4 lbs. Modular helmets are even heavier due to their flip-up mechanisms. Then there are strict safety standards and accessories, all of which pile on weight.

To lessen the load, manufacturers came up with lightweight versions of motorcycle helmets. These helmets, made of sophisticated materials derived from racing and aerospace applications, offer adequate protection without the corresponding weight penalty.


Motorcycle helmets have three components: the outer shell usually made of plastic polymers, an inner shell to cushion physical impact, and a liner for comfort.

For the outer shell, the typical helmet uses thermoplastic materials like polycarbonate or ABS. More expensive helmets use composite materials such as a mix of fiber and resin to lessen weight while retaining the same protection level. Premium helmets use exotic materials like carbon fiber and kevlar to offer the least possible weight.

For the inner layer, most manufacturers use expanded polystyrene foam or EPS(Extended Polystyrene). This layer is designed to crush upon impact to cushion the head.

Finally, there’s the padding, which provides comfort and ensures a snug fit for those long hours of riding.

The thickness of the inner EPS layer and padding can also add weight, but not as considerably as the material used in the outer shell.


In terms of weight, “beanie” helmets are the lightest. Beanies are the modern evolution of the half-shell helmets now prohibited by the Motorcycle Safety Foundation. These cover only the top of the head and usually weigh below 3 lbs. However, they are the least safe type of helmet and may not be legal in some jurisdictions. They also require separate goggles.

Open face helmets come in second on the weight scale at just over 3 lbs. Also known as ¾ helmets, they offer more protection by covering the whole head and exposing the face. Some come with half or full-face visors.

Full-face helmets provide the most protection and are considered the safest because of their extensive coverage of the head and neck. They are distinguished from open face helmets by integrating a fixed chin bar at the expense of weight, which ranges from 3-4 lbs.

At the end of the scale are modular helmets, which combine the protection of full-face helmets with open face exposure in one flip. This design enables riders to lift the facial cover when desired without having to remove the whole helmet. While convenient, the hinge structure significantly adds weight, causing it to go over 4 lbs for most models.


The last factor that adds weight is accessories. These can include aftermarket visors, face shields, breath guards and deflectors, neck rolls, and even BlueTooth speakers.

Beyond hardware add-ons and simple accessories, some cutting-edge helmets integrate HUDsaugmented reality, and even voice assistant connectivity. While they can make you feel like Iron Man talking to your very own Jarvis, all these high-tech add-ons come at a stiff cost — not just for your pocket but for your neck.


Now that you know what goes into making a lightweight helmet, how do you pick the ideal one that’s right for you?

  • Use – Are you looking for a helmet to commute with? Then full-face or modular might be the right choice to ensure maximum protection. Perhaps you’re looking to gear up for the occasional joyride? A touring helmet might be more suitable for those long rides. For cruisers and bikes that use an upright riding position, modular helmets provide more visibility. If you like to hit the trail, a dual-sport design is right up your alley.
  • Cost – While the typical SNELL helmet can cost less than $200, top-tier helmets with premium lightweight construction can cost three times as much. Composite material helmets like carbon fiber weave and kevlar typically start at $500-600, so if you want an ultra-light bucket, be prepared to have an ultra-light wallet.
  • Safety – To shed excess weight where possible, some lightweight helmets may have a thinner or low-density EPS layer. Make sure to do your homework and look up the Snell rating, in addition to the DOTEuropean Standard, or SHARP rating for the helmet, depending on your location.
  • Expandability – Most lightweight helmets are stripped down to the basics, so make sure to factor in the upgrade options down the road. See if it’s compatible with replacement liners or can accommodate sunscreen, BlueTooth headsets, and hydration packs. It’s also worth researching what accessories there are for that specific helmet, and if they are aftermarket or proprietary. 


With that out of the way, here are the best lightweight helmets you can buy this year, categorized by type and budget level.

Some of these categories overlap, and some helmets do have dual purposes. So if you dig one of our sport helmets but need a helmet for commuting, you can use the sport-helmet just fine. *Note that the listed prices of helmets are dependent on size and timeline

A worthy successor to the original GT-Air, the second-gen bucket now has a higher forehead, a larger internal sun visor, and aerodynamic improvements to better channel slipstream and isolate noise — all are essential refinements for long hours of touring. The shell is made from Shoei’s Multi-Ply Matrix fiberglass composite, while the inner liner is composed of the company’s proprietary Multi-Density EPS. This means the foam thickness varies according to the area where it’s needed the most, lowering weight while improving protection.

Mid-tier: Arai Signet-x

3.5 lbs

We felt this pick was on the high side for a mid-tier choice. However, this is one of Arai’s most popular lineups. The Signet series has the classic long oval shape that suits the majority of American heads. Like its more rounded Quantum-X cousin, this helmet has a complex laminate shell. The unique Pro Shade is a cross between a smoked face shield and a dropdown sun visor. When up, it acts like a motocross peak to block sun glare; pull it down, and the tint covers most of the visor, leaving just a small clear strip at the bottom

Top-tier: Shark Race-R Pro Carbon

For a helmet that celebrates legendary MotoGP racer Jorge Lorenzo’s final season, the Race-R fittingly uses MotoGP-level carbon/aramid fibers. Apart from its incredible lightness, the helmet’s design is optimized for unmatched stability even at speeds of 300kph.
In terms of ventilation, there are no less than four air scoops and seven extractors, thanks to extensive wind tunnel testing. The Race-R Pro is 4.5dB quieter than its non-pro counterpart and holds a 5-star SHARP safety rating. In the words of French Grand Prix and Superbike racer Randy de Puniet, “The Race-R Pro concentrates all what I am looking for in a helmet when riding my bike. In fact, it contributes to my riding performance.”

Mid-Tier: AGV K5 S

This sport touring helmet uses a carbon and fiberglass composite shell, which accounts for relatively low weight to counterbalance the complex visor mechanism. Inside are a low-profile and removable breath guard, split chin curtain, and internal visor. The visor has customizable detents that adjust to 5 different levels.

Budget: O’Neal Sierra II

It’s immediately apparent this dual-sport helmet is designed for the adventure touring crowd. Constructed from sturdy ABS, it manages to keep the weight down by ditching fancy visor mechanisms in favor of simple notches. Unfortunately, that also means replacing the inner padding with a mesh overlay. There are multiple inlets on the mouthpiece and chimney, as well as passive vents in the rear and chin, allowing for excellent airflow.
