LS2 FF805
Thunder GP
The LS2 FF805 Thunder GP has been developed with one clear objective - delivering true high-speed performance for riders who demand track-level aerodynamics and precision without compromising everyday usability. Inspired directly by modern MotoGP helmet development, the Thunder GP blends aggressive race engineering with surprisingly refined road comfort.
Track DNA
Designed using race-developed aerodynamic testing for maximum high-speed control.
Ultra Stable
Shell shaping and spoiler integration help reduce turbulence at speed.
Race Visibility
Wide visor aperture improves vision while tucked into aggressive riding positions.
Road Ready
Balanced enough for fast road riding, touring and occasional track use.
Built Around Aerodynamic Efficiency
The Thunder GP immediately feels like a helmet designed with speed in mind. The shell carries a compact and highly sculpted profile that flows naturally into the aggressive rear spoiler system, helping create smoother airflow around the helmet during fast riding conditions.
Rather than simply adding oversized spoilers for styling purposes, LS2 has clearly developed the FF805 with aerodynamic balance as a priority. This becomes especially noticeable during motorway riding and tucked sports-bike positions where airflow stability plays a major role in reducing rider fatigue.
The helmet maintains a composed and planted feel at speed while avoiding the heavy or oversized sensation that some race-inspired helmets can create during road use.
Designed For Aggressive Riding Positions
One area where the FF805 stands out particularly well is rider visibility during sports riding. The visor aperture has been developed to provide a broader upper viewing angle, allowing riders to maintain visibility while positioned low behind the screen during aggressive riding.
This creates a noticeably more natural riding experience on sports bikes compared to helmets with more restricted visor openings. Peripheral visibility also feels wide and open, helping improve awareness during both fast road riding and track sessions.
Combined with the helmet’s compact shell proportions, the Thunder GP feels purpose-built for riders who regularly ride in more committed sports riding positions.
Key Performance Areas
High-Airflow Ventilation
Large intake ports and rear exhaust channels help maintain airflow during warmer riding conditions and track sessions.
Race Spoiler System
The integrated rear spoiler improves aerodynamic stability while reinforcing the helmet’s aggressive MotoGP-inspired identity.
Race Comfort Interior
The interior liner has been designed to remain supportive and comfortable during longer high-speed riding sessions.
Final Thoughts
The LS2 FF805 Thunder GP feels far more focused and refined than many riders expect within its category. Instead of relying purely on aggressive styling, the helmet places real emphasis on aerodynamic efficiency, rider stability and genuine sports-riding usability.
For riders wanting a race-inspired helmet capable of delivering both track performance and fast road comfort, the Thunder GP offers an impressively complete package that successfully bridges the gap between premium motorsport engineering and everyday sports riding practicality.
