AERODYNAMICS & NOISE REDUCTION
Among the most important and widely studied properties in racing, no stone was left unturned during the development of the X-Fifteen’s aerodynamics. Designed and refined in SHOEI’s state-of-the-art wind tunnel facility, the X-Fifteen boasts impressive improvements in all aerodynamic performance measurables.
- Refined in SHOEI’s wind tunnel to yield the most streamlined and stable X-Series helmet ever
- Boasts impressive reductions in drag (6.1%) and lift (1.6%) as compared to its predecessor
- Bottom third of helmet (from chin bar to rear of shell) has been narrowed, and, together with updated rear stabilizer and flap designs, achieves optimal balance and stability
- Pronounced edges on the top left and right sides enhance aerodynamic performance by allowing wind to stream off the helmet with minimal resistance
- 150+ profile shape iterations were tested and refined during the X-Fifteen’s aerodynamic development
- Aerodynamic optimization was achieved in numerous riding and racing positions, with an emphasis placed on high-speed stability at speeds in excess of 218 mph
VENTILATION PERFORMANCE
Overheating while riding and racing can have a direct impact on rider fatigue and safety, which is precisely why ventilation performance was a crucial feature while designing the X-Fifteen. Wind tunnel testing throughout development revealed optimal airflow in multiple riding positions, but none more important than the aerodynamic, tucked racing position.
SHIELD SYSTEM
The X-Fifteen’s CWR-F2R racing shield system features improved visibility, functionality and performance over its predecessor, and like all SHOEI shield systems, protects against 99% of the sun’s damaging UV rays. Thanks to SHOEI’s innovative 3D injection-molding process, the CWR-F2R shield offers a distortion-free view throughout the entire X-Fifteen eyeport.
SAFETY
Few characteristics of a motorcycle helmet are as critically important as its first and second layers of defense, which is precisely why the X-Fifteen features the SHOEI-exclusive Multi-Ply Matrix AIM+ shell and Multi-Piece, Multi-Density EPS liner.
COMFORT
The X-Fifteen is equipped with a fully removable, washable, adjustable, and replaceable 3D Max-Dry Custom Interior System II that features innovative, patented comfort and performance technology.
