What Makes LS2 Products Stand Out From the Competition?

LS2 products don’t leave anything to chance. They insist on designing each of their helmets in-house to ensure they’re safe, comfortable, and functional.

LS2 ensures that every part of the helmet shells and linings, aerodynamics, and ventilation systems, among other characteristics, are optimized to provide the highest level of quality, comfort, and style.

Review of the Best LS2 Helmets

Let's take a look at this year's favorites.

Best Overall:
LS2 Subverter


  • 35 separate ventilation ports
  • Reinforced metal chinstrap rivet
  • Interior lining fabric is breathable and comfy
  • Wide eye port for an improved field of vision
  • Meets and typically exceeds safety certifications


  • Chin pads are very tight
  • It’s difficult to mount GoPro or a similar type of camera on top

Weight: 3.20lbs

Shell Sizes: Three

Shape: Intermediate oval

Style: Motocross


The LS2 Subverter helmet is a great piece of safety equipment. Though designed for professional motocross athletes, it’s also become a favorite amongst casual riders due to its superior safety technology and excellent ventilation. This product manages and disperses the energy during impact better than any other helmet.

The LS2 Subverter also has 30-35 separate vent ports, giving it some of the best ventilation we've ever experienced. It's mind-boggling how many vents are on one of the smallest and lightest helmets on the market.

Bottom Line

Aside from great safety and ventilation, the LS2 Subverter is also aerodynamic and comfortable. However, you’ll likely want to order one size larger than what the size chart suggests due to its relatively small overall fit. But overall, the LS2 Subverter is a great helmet from top to bottom.

Best for the Money:
LS2 Challenger GT Fusion


  • Includes a drop-down sun shield
  • Removable and washable interior liner
  • Face shield is one of the thickest available
  • Made from a lightweight, extra-strong, high-end fiberglass composite
  • Quick-release chin strap is quick and easy to open, even with gloves on


  • A tad loud
  • Not compatible with certain Bluetooth devices

Weight: 3.38lbs

Shell Sizes: Three

Shape: Long oval

Style: Sport/Racing


The LS2 Challenger GT Fusion helmet is one of the best choices for more racing-centered riders because it’s strong, lightweight, and has fantastic ventilation. You can tell LS2 put a lot of work into every detail; nothing feels rushed or out of place. This helmet is also rider-friendly, from how the sun visor comes all the way down to the ample space provided by the big ear pocket design.

While the Challenger GT Fusion lets in an above-average amount of wind noise and has occasional Bluetooth connection problems, everything else works great.

Bottom Line

The LS2 Challenger GT is one of the top race helmets available. It has a massive number of features for such an affordable price tag and is comprised of top-of-the-line materials.

LS2 Strobe Helmet Review and Best LS2 Modular Helmet:
LS2 Strobe


  • Excellent safety ratings
  • Distortion-free face shield
  • Very durable and affordable
  • Material is made from a breathable and hypoallergenic fabric
  • Inner glasses groove allows riders to wear eyeglasses or sunglasses


  • Tends to fog up quickly
  • Ventilation isn’t spectacular

Weight: 3.95

Shell Sizes: Two

Shape: Long oval

Style: Touring 


The LS2 Strobe is one of the better entry-level modular helmets available, though it has some minor issues. Even for a lower-priced product, it provides a decent lineup of features. These include a drop-down sun visor, a high-pressure thermoplastic technology shell, and washable cheek pads. However, they’re nothing special.

With poor ventilation coupled with the lighter sun visor tint, the LS2 Strobe is almost impossible for folks in hot, sunny areas.

Bottom Line

The LS2 Strobe is a slightly above-average helmet that has just enough features to make it a solid choice. Nothing about it will blow your socks off, and those in warmer climates should be wary, but this is still a quality piece of equipment.

LS2 Stream Helmet Review:
LS2 Stream


  • Reinforced chin strap
  • A very affordable price tag
  • Lightweight, aerodynamic shell
  • Visor is treated with a UV-resistant clear coat
  • Neck pad has a reflective patch that glows when exposed to vehicle lights


  • Fogs up often
  • Loud wind noise

Weight: 3.66

Shell Sizes: One

Shape: Long oval

Style: Street


Any helmet with a price tag under $100 is going to have issues. However, we were shocked at the LS2 Stream’s price tag because its functionality and feel are fantastic; we struggled to find anything to complain about. It's very strong and safe thanks to its kinetic polymer alloy shell. Additionally, the interior lining is comfortable, and the drop-down sun visor is a lovely added feature.

The Stream does fog up in cooler temperatures and wind noise is prevalent, but these issues exist in pretty much any helmet regardless of price.

Bottom Line

You'll be hard-pressed to find a better helmet for under $100 than the LS2 Stream. It's a perfectly balanced helmet that can be used by anyone. It fits securely and comfortably, looks great, and provides excellent head protection.

LS2 Valiant Helmet Review:
LS2 Valiant


  • Eyeglass and sunglass friendly
  • Big vent holes on top help ventilation
  • The chin vent opens and closes easily
  • Allows you to ride with the chin bar up or down
  • Aerodynamic design that isn’t too broad or narrow


  • A bit noisy at times
  • Interior liner is a pain to put back inside the shell

Weight: 3.9lbs

Shell Sizes: Two

Shape: Intermediate oval

Style: Modular


The LS2 Valiant helmet outperforms its middle-of-the-road price tag. Its fully adjustable ventilation, which allows you to control the airflow circulation, and easy-to-use quick-release chinstrap make this helmet appeal to both casual and hardcore riders.

You’ll hardly notice it weighs more than other helmets because of its comfortable yet secure fit. I forgot the Valiant was on my head during one of the longer test runs and walked into the rest stop still wearing it.

Bottom Line

 The LS2 Valiant’s comfort level, features, and functionality are impressive.  Though some have struggled with putting the interior liner back in and complained of loud wind noise, these minor criticisms are quickly forgotten because it does everything else so well.

Best LS2 Rebellion Helmet:
LS2 Rebellion


  • Offers plenty of ventilation
  • Visor is scratch-resistant
  • Very stylish and comfortable
  • Stays in place even at high speeds
  • Neck pad is equipped with reflective material for improved safety


  • Chrome color design is boring
  • Can have an awkward high head fit

Weight: 3.7

Shell Sizes: Two

Shape: Intermediate oval

Style: Touring


This is perhaps one of the most technologically advanced half helmets on the market. The LS2 Rebellion’s high-performance, lightweight kinetic polymer alloy outer shell is super strong, and the flow-through ported ventilation provides exceptional airflow.

Although this product’s safety performance doesn’t compare to a full-face helmet, it’s still a good choice for more casual riders.  The LS2 Rebellion’s overall fit is generally good but it can sit a little high on some head shapes. We also found the chinstrap and visor function and feel great.

Bottom Line

This is a good choice for riders who don’t require a full-face helmet. It offers an attractive, yet somewhat overplayed, chrome color scheme, it fits and feels good, and it has easy-to-use features.

Best LS2 Breaker Helmet:
LS2 Breaker Interceptor


  • Reasonable price tag
  • Fantastic safety rating
  • Cool design and color schemes
  • Quick-release chin strap is stress-free to use
  • Face shield is simple to take off and put back on


  • Fit can be too firm
  • Wind noise level is a little high

Weight: 3.56lbs

Shell Sizes: Three

Shape: Intermediate oval

Style: Street


Featuring a reasonable price tag, the LS2 Break Interceptor is a great entry-level helmet. It features a slightly smaller and lower profile shell that’s both comfortable and light.  The usual arsenal of features like a drop-down sun visor, emergency quick-release system, and removable face shield all work well, as does the adjustable scoop-style vent located on the top of the helmet.

The LS2 Break Interceptor’s fit is snug and comfortable, but the foam padding might be too firm for some. Also, the wind noise is rampant and loud.

Lastly, the LS2 Break Interceptor employs a kinetic polymer alloy outer shell, which is very effective at resistance penetration and dissipating impact energy during crashes.

Bottom Line

With a plethora of features, exceptional comfort, and unmatched safety, the LS2 Break Interceptor is an absolute bargain. Not many other entry-level helmets pack in as much; we highly recommend giving it a test drive.

Best Open Face Helmet:
LS2 Spitfire Bombrider


  • Affordable price
  • Good airflow circulation
  • The color scheme and design are impressive
  • Features a two-position drop-down sun shield
  • Unique and easy-to-use classically styled goggle strap


  • Average model
  • Can be a bit uncomfortable when riding at high speeds

Weight: 2.2

Shell Sizes: Two

Shape: Intermediate oval

Style: Touring


The LS2 Spitfire Bombrider’s functionality and comfort are impressive. Designed for casual rides around town, it features a lightweight shell, hypoallergenic and breathable interior lining, and a built-in ventilation system. These features are especially useful in hotter climates as they’ll prevent your head and face from overheating.

The level of safety won't be as high as a full-face helmet, but the Spitfire Bombrider is DOT certified and performed well on the SHARP safety tests.

Bottom Line

It’s not designed for high-speed or high-performance use, but the Spitfire Bombrider remains a great choice for bikers who prioritize comfort.

Best LS2 Arrow Helmet:
LS2 Arrow C EVO Indy


  • Sleek and attractive look
  • Super extensive and wide visor
  • Visor is UV- and fog-resistant
  • Designed for high-speed crash protection
  • Aerodynamic long oval shape provides a smooth ride


  • Relatively expensive
  • Inconsistent ventilation flow

Weight: 3.57lbs

Shell Sizes: Three

Shape: Long oval

Style: Racing


It might be hard getting your hands on this undervalued product, as it’s recently been discontinued and there’s no word from LS2 on whether it’ll be returning anytime soon.

Designed for racers, the Arrow C Evo Indy is light, offers exceptional ventilation, and is made with high-performance materials. It’s a shame this helmet is no longer in production.

Bottom Line

The Arrow C Evo Indy helmet’s many features and overall quality made it one of the better racing helmets around. The mystery surrounding its discontinuation has yet to be solved, but there are still plenty in circulation. It’s worth buying if you're lucky enough to find one for a fair price.

What is LS2?

LS2 is a motorsports helmet manufacturer that got its start in 1990. LS2 was the ghostwriter of the helmet industry during its first years in operation, designing and producing helmets for other companies to brand.

In 2007, founder and owner Arthur Liao established company headquarters in Barcelona and debuted the first LS2-branded helmets at the Milan Motorcycle Show. After a successful showing, LS2 (short for Liao’s systems) garnered international attention, soon becoming one of the most sought-after helmet brands.

LS2 now produces over 1,000,000 motorcycle helmets that are distributed worldwide.

How Do I Choose an LS2 Helmet?

Inexperienced should gather as much information as possible to determine which LS2 model suits them best. Here are a few things you’ll want to keep in mind.

Riding Style

Motorcycle helmets are usually designed for specific riding styles. Make sure your motorcycle and how you utilize it coincide with your helmet choice.


LS2 helmets have varying comfort levels. The safest aren’t the most comfortable, and vice versa. What’s best for you depends on your riding style.


Some helmets are loaded with features while others only have a few. Make sure you choose a product with attributes that are useful for you.

Types of LS2 Helmets

Common types of LS2 helmets you can choose from.

Full Face

Full-face helmets are widely considered to be the safest type because they cover the whole head, the base of your skull, and face.

Half Helmet/Open Face

Open-face helmets only cover the very top of the head. These are the most comfortable, but they leave you more exposed to any potential dangers.


Modular helmets are a combination of full-face and open-face helmets. They feature a flip-up front part that can be used in either the open or closed position.


Off-road/motocross helmets cover the entire head and are usually loaded with special features that help protect and provide riders a competitive edge.

How Do LS2 Helmets Compare?

Read on to find out the difference of LS2 to other brands.

LS2 Helmet vs MT


LS2’s and MT’s overall builds, features, price, and safety certifications closely resemble each other. Both brands use the same general materials in their outer and inner helmet components and typically have the same features packaged in different ways.


MT helmets have a slightly heavier weight and thinner interior padding. Each brand also has its own unique set of features, depending on the price range. Additionally, LS2 and MT have unique color schemes and art designs, as well as size charts and fit.

Spyder vs LS2 Helmets


Spyder and LS2 helmets are very similar in price, materials, features, and safety. They’re both highly regarded by riders.


There are very subtle differences in the overall look and feel of these two helmet brands. They also have slightly different weights, sizing guides, and feature packages.

Who Shouldn’t Choose an LS2 Helmet?

LS2 pretty much has a helmet for every riding style. You’ll want to adhere to a bit of common sense when deciding which one is best suited for you.

The more comfortable styles are for casual riding, while racing and sport types are for high-speed riders. You don’t necessarily have to be a competitive racer to get quality use out of a racing helmet, but the same can’t be said for high-speed riders using anything other than a full-face model due to safety limitations.


The helmets listed here are some of the best on the market. However, if they don't suit you, the same guidelines laid out here apply to other helmet brands. Just remember that proper fit is more important than the look and price.
