Sophisticated aerodynamic system
Highly specialized aerodynamic system for high-speed riding. Developed and tested in the SHOEI wind-tunnel, it reduces drag and lift of the helmet. This decreases the stress that the neck of the rider must overcome. Lift is reduced by 3% and drag by 10% compared the the X-Spirit II.

Rear stabilizer with equipped flaps
With the implementation of the rear flaps, the X-Spirit III reduces the shaking of the helmet by 50% compared the X-Spirit II. This is essential to have a clear view during high-speed riding. Two different rear flaps are available for different conditions and track layouts. Smaller ones for slow, curvy tracks and bigger ones for faster, straighter layouts.
