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.

Born from motorsport engineering, the LS2 FF805 Thunder in Aero Flash Black is a track-bred full-face helmet that delivers genuine racing performance for the road. Its full carbon fibre shell keeps weight to an astonishing 1,280 g (±50 g, size M) while the integrated race spoiler generates the aerodynamic stability you need at speed — whether you are chasing lap times or making the most of an open road.
Key Features
- Full 100% carbon fibre shell construction — maximum impact resistance at minimum weight
- Integrated race spoiler optimised for aerodynamic stability at high speeds
- Pinlock Max Vision 120 anti-fog insert included — clear vision in all conditions
- Emergency cheek-pad release system for safe, rapid helmet removal after an incident
- EPS-channelled ventilation system with multiple forehead and crown vents for sustained airflow
- Removable, washable X-Static© Silver antibacterial liner — stays fresher on long track days
- Prepared for tear-off strips — a genuine racing convenience straight from the box
Race-Engineered Construction
LS2 developed the FF805 Thunder directly from their motorsport programme, and the Aero Flash Black finish showcases the aggressive race aesthetic that sits alongside the helmet's functional credentials. The shell is manufactured in three distinct sizes — not merely offered in multiple sizes from one mould — so the fit geometry scales correctly with your head circumference. Safety-reflective panels improve visibility in lower-light conditions, a thoughtful touch for riders who do not limit themselves to dry summer afternoons.
The reinforced chin strap and double-D-ring retention system meet UNECE 22-06 certification requirements, providing a secure and verifiable closure under competition and road conditions alike. The wide, scratch-resistant visor offers outstanding peripheral vision, and its mechanism is prepared for tear-off discs so that circuit use requires no additional modification.
Comfort & Ventilation
Multiple forehead and crown ventilation ports work in concert with EPS-moulded internal channels to draw fresh air through the helmet and exhaust heat efficiently. The removable interior — treated with X-Static© Silver antibacterial technology — can be fully extracted and machine-washed, keeping the helmet hygienic across an entire season of intensive use.

- S — 55–56 cm
- M — 57–58 cm
