The SHOEI X-Fourteen and X-Fifteen Lower Air Spoiler is a small part that makes a big difference when it comes to how your helmet performs at speed. If your original spoiler is damaged or missing, this genuine replacement is designed to fit perfectly just below the lower vent at the chin bar, sliding smoothly between the shell and EPS liner. Once in place, it helps reduce wind drag and cut down on turbulence, giving you a more stable and comfortable ride. It is easy to install and a simple way to keep your helmet feeling just right every time you gear up.
