How to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible tape measure.
It is important that the tape measure runs around the widest part of the head – only then will you get a correct result.
Place the tape measure at the front, about 1–2 cm above the eyebrows, and run it along the sides above the ears.
At the back, the tape must run over the largest part of the back of the head (not too low on the neck). The tape may run slightly at an angle – what matters is that it sits all the way around the largest points of the head.
Make sure the tape measure sits snugly but does not dig in. Measure 2–3 times for the most accurate result. You can then compare the measured value in centimetres (cm) with our size chart.
Tips for an accurate result
- Keep hair flat (e.g. do not measure over a voluminous hairstyle)
- Keep the tape horizontal, i.e. along the largest circumference
- Do not measure too loosely
- For values between two sizes:
→ usually choose the larger size (depending on helmet model / fit)
Important note on fit
The right helmet should fit firmly without causing uncomfortable pressure points.
A new helmet may feel a little tighter at first, as the inner lining adapts slightly over time.

Komai is the most graphic of the four patterns here — bold interlocking shapes wrapping the sides and crown, in white, blue and red under a gloss coat.
Everything that is usually an extra
What arrives in the box goes beyond the helmet: a Pinlock 70 MaxVision anti-fog insert already matched to the visor, a carrying bag, and reflective stickers. Fitted to the helmet itself are a tinted drop-down sun visor with easy removal and a magnetic chin curtain — the two features that separate a touring helmet from a commuter one.
About the Komai White/Blue/Red finish
Blue dominates the sides with white opening the pattern up and red sharpening the transitions. The gloss finish gives each panel its own highlight, so the graphic reads differently depending on the angle. Like most three-colour LS2 decors it is asymmetric — the two sides of the helmet do not match, which is worth knowing if you have a preferred camera side. The white content also keeps daylight visibility high.
A large top intake, and what it feeds
LS2 built this helmet around one large crown intake, and that is where its ventilation claim comes from. Air enters at the top, travels through channels moulded into the polystyrene, and leaves through rear exhausts. A second intake at the chin clears the visor and cools your face, and a breath deflector keeps exhaled air off the screen.
The release you hope never to need
Retention is a ratchet fastener: set the length once, one click thereafter, gloves on. What sets this helmet apart in its class is the emergency release — red tabs at the base of the cheek pads that let the pads be pulled out sideways, so the shell lifts away from an injured rider's head rather than being dragged over it.
Two screens, one shell
Two screens, one shell. The outer visor is hardcoated, UV-stable, Max Vision cut, button-locked and Pinlock-equipped as supplied. Inside sits a tinted sun visor on a slider, and unlike most it is designed to be removed by hand for cleaning rather than smeared clean in place.
What the ECE 22.06 plaque actually means
Every helmet on this page carries ECE 22.06, and it is worth knowing what that plaque now costs a manufacturer. The standard it replaced, 22.05, struck the shell at five fixed points and measured only how hard the head was stopped. 22.06 strikes up to eighteen points, at more than one speed, and adds a test that did not exist before: the helmet is dropped onto an angled anvil faced with abrasive paper, so the laboratory can measure how far the head is spun as well as how hard it is stopped.
That matters because rotational acceleration is what tears the bridging veins between brain and skull, and until 2021 no European standard measured it at all. 22.06 also tests the visor, and any accessory fitted to the helmet is tested in place rather than removed for the exam. Since January 2024 a new helmet cannot legally be sold in the EU without it.
Fit and shell sizes
3 shells, XXS to 3XL. It is the sensible middle ground: not the six-shell extravagance of a race helmet, and a long way from the one-size-fits-all moulding that makes small helmets look inflated and heavy.
The bit you actually touch
The liner is hypoallergenic, antibacterial, breathable and removable, and LS2 describe it as their maximum-comfort interior — which in practice means more crown padding than a helmet at this price usually carries. Recesses are moulded for LS2's current Bluetooth system, so a comms unit does not have to be wedged in.
On noise
Wind noise is the specification manufacturers never quote, because it depends more on your bike than on their helmet. What the helmet controls is the seal at the neck roll, the gap under the chin bar and the vents. The chin curtain here is magnetic, which is not a gimmick: a popper-fastened curtain gets left off after the second cleaning, and a curtain that is not fitted does nothing. The sun-visor housing does widen the shell slightly at the temples compared with a helmet without one, which is a small aerodynamic cost for a large practical gain.
What it does not control is the airflow leaving your screen. If a helmet is loud on one motorcycle and quiet on another, the screen is usually the reason. Plugs cost a euro and do more than any shell shape.
1600 grams, and what it buys
1600 grams, mid-size shell, no accessories. That is a real number and a real trade-off — it is the heaviest LS2 helmet in this shop. What it buys is everything the lighter models leave out, and on a touring bike with a screen the difference is far less noticeable than it is on a naked at 130 km/h.
1600 grams (±50 g), mid-size shell, no accessories — the industry convention, so the number is comparable with any other manufacturer's. What it buys you is fatigue: neck strain over a long ride is a function of mass, and a hundred grams that mean nothing in a showroom mean a great deal at the end of a four-hour stint.
Within our own LS2 line-up only 5 helmets are lighter, and each of them costs more.
Where it sits in our LS2 range
Eight LS2 full-face models are listed here and they form a ladder rather than a wall of choices. The Storm III is the equipment high point of the affordable half.
| Model | Shell | Weight | Sun visor | Pinlock | RRP |
|---|---|---|---|---|---|
| FF808 Stream II | KPA | 1550 g | yes | prepared | from 129 € |
| FF818 Storm III | KPA | 1600 g | yes | included | from 199 € |
| FF811 Vector II | HPFC | 1500 g | yes | included | from 259 € |
| FF817 Challenger II | HPFC | 1500 g | yes | included | from 329 € |
When something wears out
Worth knowing before you buy rather than after: everything on this helmet that wears out can be replaced individually. Liners in all eight sizes seven replacement visors from clear to iridium, the tinted sun visor, the chin curtain, chin bar trim, nose guard, ratchet mechanism and vent covers in six finishes.
The interior is the part that decides how long the helmet stays honest. Sweat and hair oils break down the foam, the fit loosens, and riders conclude the helmet is finished when the shell is untouched. The full parts list is in the FF818 Storm III Kit.
