On October 21, 2022, Shoei formally announced its newest full-face helmet, the X-Fifteen, in Japan. Helmet development doesn’t happen in a vacuum, but it does frequently involve a whole lot of time in a wind tunnel and on race tracks. Combining knowledge that the firm accumulated over time, the X-Fifteen is designed to offer impressive aerodynamic performance, even at speeds at and above 350 kilometers per hour (or 217.48 miles per hour).
Lift is reportedly reduced by 1.6 percent as compared to the X-Fourteen, and drag resistance is lowered by 6.1 percent. Inside the visor, Shoei says it’s incorporated vortex generation technology to ensure a quieter headspace for riders who wear this helmet—all the better to concentrate on going fast, of course. Naturally, the visor is Pinlock- and tearoff-ready.
