DescriptionThe whole story

The LS2 FF805 Thunder Carbon is a race-bred full-face helmet that translates genuine motorsport engineering into a practical, everyday package. Built around a 100% carbon fibre shell, it delivers serious protection at a weight that makes long days in the saddle genuinely comfortable — all finished in a natural exposed-carbon matte that looks as purposeful as it performs.

Key Features

  • 100% carbon fibre shell construction for an outstanding strength-to-weight ratio and all-day wearing comfort
  • Three shell sizes ensure a precise, proportionate fit across every head size from XS to XXL
  • Prepared for Pinlock Max Vision 120 anti-fog insert — included as standard, so you are ready to ride the moment it arrives
  • Racing spoiler integrated into the shell profile for maximum aerodynamic stability at motorway and track speeds
  • Multiple forehead and crown vents channelled directly through the EPS liner for efficient, draught-free airflow
  • Emergency cheek-pad release system allows first responders to remove the helmet safely without moving your neck
  • Double-D-ring retention system and reinforced chin strap provide secure, rattle-free fastening every ride

All-Day Usability

Where many carbon helmets ask you to choose between performance and practicality, the FF805 Thunder Carbon sidesteps that compromise. The wide, scratch-resistant visor gives a generous peripheral field of view on urban commutes and twisty back roads alike, while the Pinlock Max Vision 120 lens — included in the box — eliminates fogging without any additional outlay. The removable inner lining carries an X-Static© Silver antibacterial treatment, meaning it stays fresher for longer and washes easily when it does need attention. Safety-reflective patches add a layer of passive visibility for early-morning or late-evening rides.

Race-Derived Construction

LS2 developed the FF805 directly from its involvement in competitive motorsport. The single-piece 100% carbon fibre shell is formed in three distinct sizes rather than being artificially padded to cover a wider range — a detail that contributes both to the precise fit and to the 1,280 g (±50 g, size M) target weight. The EPS liner is fully channelled to align with the ventilation ports, so airflow management is a structural feature rather than an afterthought. Tear-off posts are integrated into the visor surround for circuit use, and a set of tear-off films is included straight from the box.
