X803
ADJUSTABLE STABILITY DEVICE (ASD)
An innovative adjustable aerodynamic spoiler is integrated in the rear part of the shell.
The product of extensive wind tunnel testing and vast racetrack experience, the spoiler
optimises the helmet's aerodynamics during riding, improving stability at high speeds
and helping the venting of hot air from the interior through outlet vents integrated di-
rectly in the spoiler.
Its profile, and thus its aerodynamic performance, can be adjusted to one of two availa-
ble configurations to better suit different riding positions and styles (Fig.34).
