DescriptionThe whole story

Built on knowledge earned at the highest level of motorsport, the LS2 FF805 Thunder Carbon in Diamond Blue/Red is a full-face race helmet that places certified safety at its very core. Homologated to the latest UNECE 22-06 standard, its 100% carbon fibre shell delivers exceptional impact resistance at a weight of just 1,280 g (±50 g, size M), making it one of the most credible track-to-road lids in LS2's lineup.

Key Features

  • UNECE 22-06 certified — meets the most stringent current homologation standard for road and circuit use
  • 100% carbon fibre shell construction across three shell sizes for a precise, lightweight fit at every head circumference
  • Race-derived GP aero spoiler optimises airflow stability and reduces lift at speed
  • Wide, scratch-resistant visor prepared for Pinlock Max Vision 120 anti-fog insert — included in the box
  • Emergency cheek-pad release system enables fast, safe helmet removal after an incident
  • X-Static© Silver antibacterial liner, fully removable and machine washable
  • Ready for tear-off film systems; safety-reflective patches included for low-light visibility

Shell & Construction

LS2 manufactures the FF805 Thunder Carbon in three distinct shell sizes, ensuring the helmet hugs the head correctly across the full XS–XXL size run rather than padding out a single oversized shell. The monocoque carbon fibre structure is engineered for maximum energy absorption, while channelled EPS ventilation guides airflow efficiently from the multiple forehead and crown vents through the liner and out via the rear exhaust ports. The result is a racing environment inside the helmet even when the pace drops to road riding.

Visor & Ventilation

The broad, optically clear visor offers superior peripheral vision — a deliberate design choice informed by circuit feedback. It accepts the Pinlock Max Vision 120 insert (supplied), virtually eliminating fogging in cold or wet conditions. For track days, the visor is also prepared for tear-off films, keeping your line of sight clear lap after lap. The gloss finish of the Diamond Blue/Red livery is complemented by the clean visor aperture, which sits flush with the chin guard for aerodynamic consistency.

Comfort & Safety Systems

Inside, the removable liner is treated with X-Static© Silver technology — a silver-fibre antibacterial system that suppresses odour and moisture build-up on long stints. The double-D ring retention strap is reinforced for positive closure under load. Critically, the emergency cheek-pad release system allows first responders to remove the helmet without moving the rider's neck and spine — a feature that reflects LS2's commitment to real-world safety beyond the certification label. Safety-reflective patches are sewn into the shell for conspicuity in low-light conditions.

Sizing Guide

Measure approximately 1 cm above the ears around the widest part of your head to find your size:

  • XS — 53–54 cm
  • S — 55–56 cm
  • M — 57–58 cm
  • L — 59–60 cm
  • XL — 61–62 cm
  • XXL — 63–64 cm

Fitment & Compatibility

The LS2 FF805 Thunder Carbon is a universal full-face helmet suitable for road riding and circuit use. It is not model- or motorcycle-specific and fits any rider whose head measurement falls within the size chart above. The helmet is particularly well suited to track day riders and sport-touring enthusiasts who require certified race-level protection on both public roads and closed circuits.
