Shoei released its flagship road racing helmet, the X-SPR Pro, in Europe in June, 2022. After testing the prototype in MotoGP, the new model succeeded the brand’s iconic X-Spirit 3. In the United States, that same model goes by the X-Fourteen moniker, and Shoei finally revealed its predecessor, the X-Fifteen, on May 4, 2023.
For the new model, the Japanese helmet maker maintains its proprietary AIM+ (Advanced Integrated Matrix) shell construction. However, the designers mold the layers of fiberglass, organic/glass fibers, and polyester resin into an improved aerodynamic shape. The model’s narrowed lower third (chin bar to rear) and new cranial ridges work in concert with the integrated rear spoiler, lower air spoiler, and rear stabilizer flaps. Complemented by the vortex generators on the Pinlock-compatible CWR-F2R shield, the fine-tuned shell reduces drag by 6.1 percent and lift by 1.6 percent.
