The Shoei X-Fifteen's highly customizable inner padding ensures the helmet stays firmly on your head, on every straight, and in every curve of the race track.

By replacing the neck pad from the original size S9 with the optional, thicker size S13, you can specifically adjust the fit of the helmet to your individual head shape or personal preferences.

OEM Sizing:

• XS/S = S9
• M = M9
• L = L9
• XL/XXL = XL9
