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.

Shaped by the demands of professional racing, the LS2 FF805 Thunder Carbon in the Loris Baz 2024 Replica livery is a full-face helmet engineered to keep you comfortable and focused across an entire day on track or road. Its 100% carbon fibre shell delivers extraordinary rigidity at a weight of approximately 1,280 g (size M, ±50 g), while the fully removable, washable X-Static© Silver antibacterial liner moulds to your head and stays fresh through long sessions.
Key Features
- 100% carbon fibre shell produced in three shell sizes for a precise, comfort-optimised fit across all head sizes
- Multiple forehead and crown vents channelled through the EPS liner for active, even airflow throughout the ride
- Pinlock Max Vision 120 ready — anti-fog insert included in the box for clear vision in all conditions
- Emergency cheek-pad release system allows first responders rapid, safe helmet removal
- Removable and machine-washable liner with X-Static© Silver antibacterial treatment for all-day hygiene and comfort
- Race spoiler integrated into the shell profile for maximum aerodynamic stability at speed
- Prepared for tear-off strips for uninterrupted vision during track use
Shell & Interior
The FF805 Thunder Carbon is built on a monocoque 100% carbon fibre shell, offered in three shell sizes so that every head circumference gets the thinnest, lightest possible structure rather than a single oversized shell padded down. The result is a helmet that sits naturally without pressure points — a tangible advantage during extended rides.
Inside, the multi-density EPS liner is channelled to align with the ventilation inlets and outlets, pulling warm air away from the scalp continuously. The cheek pads and crown liner are fully removable and washable, and the reinforced double-D ring chin strap with safety-reflective patches keeps both comfort and visibility in check at every hour of the day.
Visor & Aerodynamics
The wide, scratch-resistant visor offers excellent peripheral vision and is prepared for Pinlock Max Vision 120 inserts. The racing spoiler at the rear adds downforce and prevents helmet lift at motorway and circuit speeds, keeping your neck muscles relaxed across high-speed laps or touring miles alike. Tear-off preparation lets you run a fresh line of vision without pulling into the pits.
