Features
The S1-XR GP was designed and developed in Italy using the most advanced digital tools. It has undergone rigorous testing by Suomy riders to ensure its top-tier performance.

3 Shells
Available helmet sizes: from XS to XXL.

Visible Carbon
The shell is made from thin carbon, Kevlar, and fiberglass.

Tricarboco
The outer shell is made from Tricarboco fibers, providing a lighter, harder, safer, and impact-resistant shell.

Prepared for Hydration
Ready for a hydration system.

FIM Approved
The S1-XR GP meets the FIM standard, the highest standard for motorcycle helmets required for competition.

Aerodynamic
The S1-XR GP features improved aerodynamics for smoother handling and professional racing performance. This was achieved through more than three years of testing in wind tunnels and on racetracks to optimize aerodynamics in various riding positions (straight, cornering, and braking).

Wind Tunnel Tested
The aerodynamic performance is optimized to provide the best comfort at all speeds.

Stabilizing Spoiler
To ensure exceptional aerodynamic penetration and extraordinary stability at various speeds.

CX 0.33
The most aerodynamic straight-line performance.

CX 0.39
The most aerodynamic in corners.

Ventilation
The S1-XR GP has seven air intake channels that, along with a carefully integrated channel system, ensure excellent air circulation inside the helmet.

Air Vents
Seven efficient air intakes and two exhaust vents.

Channeled EPS
Channeling of the inner shell to ensure maximum heat dissipation.

Breath Deflector
An optional tool to prevent fogging of the visor.

Chin Curtain
To provide better air and noise insulation from the bottom of the helmet.
