S1-XR GP meets FIM Standard, which is the top of the motorcycle helmet standards necessary for racing competitions.


S1-XR GP boasts improved aerodynamics for a smoother ride and professional racing performance, thanks to over three years of wind tunnel and track tests to optimize aerodynamics in various riding positions (straight, cornering and braking position).

Wind Tunnel Tested

The aerodynamic performances are optimized to allow the best comfort at all speed

Stabilized Spoiler

To guarantee an exceptional aerodynamic penetration and extraordinary stability at various speeds

CX 0.33

The most aerodynamic on the straight.

CX 0.39

The most aerodynamic in cornering.


S1-XR GP spots seven air intake ducts which work in conjunction with a neatly integrated channel system, guaranteeing excellent airflow inside the helmet.

Air Vents

Seven air intakes and 2 effective air extractors

Channeled EPS

Canalization of the inner shell to guarantee the maximum heat dissipation

Breath Deflector

An optional tool that helps to prevent fogging of the face shield

Chin Curtain

To ensure a better insulation from the air and noise from the bottom of the helmet

Comfort Liners

The Suomy R&D department created a package of solutions that enhance comfort, versatility with breathable technical fabric and a balanced fitting suitable for any type of riding.
