DescriptionThe whole story

Shaped by motorsport knowledge and built around a full day on track or road, the LS2 FF805 Thunder Carbon in Diamond White/Grey is a race-bred full-face helmet engineered to sit naturally on your head from the first lap to the last. The 100% carbon fibre shell keeps mass to a minimum — approximately 1,280 g in size M — so neck fatigue stays where it belongs: nowhere. Add an anti-fog Max Vision Pinlock system straight out of the box and outstanding peripheral vision, and this is a helmet designed to let you concentrate entirely on riding.

Key Features

  • Full carbon fibre shell produced in three shell sizes for a precise, comfort-optimised fit across all head sizes
  • GP-specification race spoiler for maximum aerodynamic stability at high speed
  • Wide, scratch-resistant visor prepared for Pinlock Max Vision 120 anti-fog insert — included in the box
  • Removable and washable interior liner with X-Static Silver antibacterial treatment for long-ride freshness
  • Emergency cheek-pad release system for safe and rapid helmet removal after an incident
  • Multiple forehead and crown vents channelled through the EPS liner for genuine airflow management
  • Double D-ring retention system with reinforced chin strap and safety-reflective patches for low-light visibility

All-Day Comfort and Fit

Three separate shell sizes mean the FF805 Thunder Carbon is not simply a single moulding stuffed with extra padding — each size group gets a shell proportioned to match the head it covers. The result is a balanced, low-pressure fit that remains comfortable across long riding days. The X-Static Silver antibacterial lining wicks moisture and resists odour, keeping the interior fresh even when temperatures rise, while the fully removable liner can be taken out and machine-washed between trips.

Ventilation is channelled directly through the EPS liner rather than simply across it, so air that enters the forehead and crown vents actually flows over the head before it exits. In combination with the low overall weight, this makes sustained high-speed riding — whether on circuit or open road — noticeably less tiring than helmets built around a heavier fibreglass or composite shell.

Race-Ready Construction

The 100% carbon fibre shell of the FF805 Thunder Carbon is the same fundamental architecture used in LS2's motorsport programme. Carbon's high strength-to-weight ratio provides outstanding impact resistance while keeping the helmet light enough to benefit riders who demand both protection and comfort across extended sessions. The integrated race spoiler is not a styling detail — it manages airflow at the rear to reduce lift and buffeting, keeping the helmet stable at motorway and circuit speeds alike.

The wide visor is prepared for tear-off film — a set is included — so track riders can keep vision clear across a full race or test day without reaching for a cloth. The same visor accepts the included Pinlock Max Vision 120 insert, eliminating fogging in cold or wet conditions on the road.
