LS2 Assault Helmet Review: Is It Still Worth Buying?

I spent quite a bit of time looking into the LS2 Assault because it has an interesting mix of features for a relatively low price. The more I compared owner feedback with the actual specs, the more I understood why this helmet has stayed popular.

In this LS2 Assault helmet review, I’ll cover the things that matter on real rides: fit, comfort, noise, airflow, visor performance, safety features, and the small annoyances that are easy to miss when you only read the product description.

What I Like Most About the LS2 Assault

The Assault is a full-face sport-touring helmet. It is also sold as the LS2 Storm in some markets, and it uses LS2’s Kinetic Polymer Alloy, or KPA, shell. The helmet has a multi-density EPS liner, drop-down sun visor, Pinlock-ready main shield, and metal quick-release buckle.

What stood out to me is how much useful equipment LS2 packed into one fairly affordable helmet.

Feature	My Take
KPA shell	Light and practical
Drop-down sun visor	Very handy for daily rides
Pinlock-ready shield	Excellent for cool or wet weather
Metal quick-release buckle	Fast and easy to use

LS2 Assault Helmet Review: The Features That Matter

The wide eye port is one of the better details. Good side vision makes city riding easier, especially when checking traffic.

The main visor also uses optically correct Class A polycarbonate. The included Pinlock insert is another big plus because visor fog can become a real pain when temperatures drop or humidity rises.

How Does the LS2 Assault Fit?

Fit is where I would spend the most time before buying. The Assault uses an intermediate-oval shape, so it should suit many riders, but head shape still matters more than the size printed on the box.

The padding can feel snug when the helmet is new. That is not always a bad sign. Helmet padding normally settles a little with use, but you should never accept painful pressure just because someone says a helmet will “break in.”

Fit Concern	What I Would Do
Cheeks feel snug	Give them time if there is no pain
Forehead pressure	Try another size or shape
Helmet moves easily	Do not size up
Unsure between sizes	Measure your head first

LS2 Assault Helmet Review: Sizing Mistakes to Avoid

One mistake I see often is choosing a helmet by hat size. I would not do that.

Measure around your head just above the eyebrows and ears, then compare the measurement with the manufacturer’s chart. RevZilla lists sizes from 2XS through XL on its current product information, with larger sizes available on some Assault variants.

Is the LS2 Assault Comfortable on Long Rides?

Comfort is one of the strongest parts of the Assault. Its interior uses moisture-wicking material, and the cheek pads are shaped to sit closely around the face. Some riders report that the padding feels tight at first but becomes more comfortable after several rides.

I also like that the helmet has speaker pockets. That makes adding a Bluetooth communicator much easier.

Comfort Detail	Real-World Benefit
Moisture-wicking liner	Helps on warm rides
Laser-cut cheek pads	Snug, supportive feel
Speaker pockets	Easier Bluetooth installation
Removable liner	Easier cleaning

How Good Is the LS2 Assault Ventilation?

Ventilation is another area where the Assault does well for its price. There is a chin vent and top vents, with rear exhaust ports helping move air through the helmet. The vent sliders are large enough to operate while wearing gloves.

That said, I would not expect miracles in very hot weather. Helmet vents can move air, but they cannot turn a full-face helmet into an air conditioner.

LS2 Assault Helmet Review: Does the Visor Fog?

This is one area where I would strongly recommend using the Pinlock insert.

The chin vent sends some air toward the shield, but reports suggest that it may not always prevent fog on its own. Fortunately, the Assault comes prepared for Pinlock, and many versions include the insert.

Riding Condition	Best Approach
Cool morning	Use the Pinlock
Heavy rain	Keep airflow open
Hot, dry ride	Open the vents
Stop-and-go traffic	Expect more fog

Is the LS2 Assault Noisy?

This is probably the biggest weakness I would keep in mind.

Noise is very rider-dependent. Bike type, windscreen height, riding speed, head position, and even ear shape can change what you hear. Owner feedback is mixed, with some riders calling it reasonably quiet and others reporting strong wind noise.

So I would not buy the Assault expecting premium-level silence.

Noise Situation	My Advice
City commuting	Usually manageable
Highway riding	Wear earplugs
Tall windscreen	Often more comfortable
Naked bike	Expect more wind noise

Is the LS2 Assault Safe?

The Assault uses a KPA shell and multi-density EPS liner. Depending on market and version, certification can include DOT and ECE 22.05.

It also has an Emergency Release System in the liner on versions reviewed by retailers, which can help emergency personnel remove the helmet more safely after a serious crash.

One thing I would not do is assume that a lower price means poor protection, or that a more expensive helmet automatically fits better. The correct fit is critical.

What Are the Downsides of the LS2 Assault?

After looking at the specs and a large amount of rider feedback, a few trade-offs stand out.

The biggest ones are noise, the limited number of shell sizes, and the fact that some riders report sizing differences or warm-weather ventilation concerns. RevZilla’s customer feedback also mentions occasional fogging and sizing issues.

Potential Problem	Better Approach
Wind noise	Use quality earplugs
Tight new padding	Check for painful pressure
Fogging	Install the Pinlock
Buying online	Measure your head first

Is the LS2 Assault Worth Buying?

For the right rider, I think it makes a lot of sense.

The Assault gives you features that are often missing from budget helmets: a built-in sun visor, wide main shield, Pinlock compatibility, good ventilation, comfortable padding, speaker pockets, and a convenient metal quick-release buckle. Owner ratings are generally strong, although complaints about noise show up regularly.

There is one important catch: the model is now discontinued at major U.S. retailers such as RevZilla and Cycle Gear, so availability can depend on remaining stock.

LS2 Assault Helmet Review: Who Should Buy It?

I would look at the Assault if you mainly commute, tour, or ride on the street and want a full-face helmet with useful features without spending premium money.

I would look elsewhere if your top priority is extremely low wind noise, a very specific head shape, or the newest safety standard.

Rider Type	Verdict
Daily commuter	Good choice
Sport-touring rider	Good fit for the role
Budget-conscious rider	Strong value
Track-focused rider	Look for a race helmet
Noise-sensitive rider	Consider a quieter model

Final Thoughts

My biggest takeaway from this LS2 Assault helmet review is that the Assault gets the important everyday features right. It is comfortable, practical, well equipped, and designed around normal street riding rather than trying to be something it is not.

The main thing I would watch is fit. After that, noise is the biggest compromise. If you find the right size and use ear protection, the Assault can make a lot of sense as an affordable full-face motorcycle helmet.
