Optimal Aero
The S-R10 prioritizes track-speed, comfort and stability. This Limited Edition features Jorge Martin’s Flyte graphic, honoring the rider who helped develop it. Enhanced stability and aerodynamics come from side winglets, an optional Race Spoiler reducing drag by 4.54%, and turbulators along the face shield edge for improved aero-acoustic performance.

A-Head Of The Competition
The Supertech R10 features Alpinestars' A-Head system, enabling precise adjustment of helmet height and angle. This customization enhances comfort and optimizes your field of view by positioning the eye port for your head shape and riding stance.
Shielded
Designed for safety, clarity, and weight savings, the race-ready S-R10 face shield features varying thicknesses, 2.6mm front tapering to 1.6mm at the sides and top turbulators for aerodynamics. Its drop-down design enhances the field of view in riding position, ensuring you never miss an apex, just like 'Martinator.'

Advanced EPS
Alpinestars prioritized protection in the S-R10, integrating advanced go-fast tech with reinforced external and internal components. Six different densities of EPS foam are strategically layered to absorb and dissipate impact energy effectively during a crash.
