Designed and refined in SHOEI’s state-of-the-art wind tunnel facility, the X-Fifteen boasts impressive improvements in all aerodynamic performance measurables, most notably a 6.1% reduction in drag and a 1.6% reduction in lift [as compared to its predecessor].
Thanks to SHOEI’s superior shell molding technology, the bottom third of the helmet (from the chin bar to the rear of the shell) has been strategically narrowed, and together with updated rear stabilizer and rear flap designs, the balance and stability of the all-new X-Fifteen is next level.
During the evolution of the X-Fifteen’s 150+ profile shape iterations, SHOEI engineers focused on aerodynamic optimization while in numerous riding and racing positions. Special emphasis was placed on the enhancement of high-speed stability [tested at speeds in excess of 218 mph] while reducing the negative forces that can inhibit a rider’s performance on race day. Mission accomplished.
Putting the helmet through its paces in SHOEI’s in-house wind tunnel throughout development revealed optimal airflow in multiple riding positions, but none more important than the aerodynamic, tucked racing position.
Featuring seven (7) closable air intakes and six (6) exhaust outlets—all strategically shaped and located to maximize airflow and negative air pressure suction to the rear of the helmet—the X-Fifteen’s ventilation performance is on another level. Helping to pull cool, refreshing air through the helmet, the X-Fifteen’s EPS tunnels have been enlarged from 6mm to 10mm in depth, dramatically increasing cool-air volume and the rate of hot-air expulsion.
Additionally, significant improvements have been made to the innovative cheek pad cooling system by increasing the number of holes delivering refreshing air to the rider’s cheek area. Channels cut through the EPS liner and corresponding air holes located in the cheek pad foam work in harmony with exhaust outlets to clear warm, humid air from the rider’s face with even greater efficiency.
MULTI-PLY MATRIX AIM+ SHELL
Few characteristics of a motorcycle helmet are as critical as its first-layer of defense, which is precisely why the all-new X-Fifteen features the SHOEI-exclusive Multi-Ply Matrix AIM+ Shell construction. Combining a six-ply matrix of fiberglass with lightweight organic and high-performance fibers, the X-Fifteen’s proprietary AIM+ shell provides optimal impact-absorption, strength and elasticity, and is available in four shell sizes to ensure a custom fit for heads between the sizes of XS-XXL. The X-Fifteen is both Snell M2020R and ECE22.06 certified.
3D MAX-DRY CUSTOM INTERIOR SYSTEM II
The X-Fifteen is equipped with a fully removable, washable, adjustable, and replaceable 3D Max-Dry Custom Interior System II. SHOEI’s exclusive Max-Dry liner material absorbs and dissipates sweat and moisture twice as fast as traditional nylon interiors, and in combination with the X-Fifteen’s superior ventilation system, keeps racers and aggressive riders alike cool and dry during intense riding sessions. Additionally, the innovative cheek pad cooling system delivers refreshing air to the rider’s cheek area thanks to channels cut through the EPS liner and air holes strategically located in several areas of the foam.
Similar to the X-Fourteen interior, the X-Fifteen’s cheek pad system utilizes a patented angle adjustment mechanism to change the position of the helmet by up to 4-degrees to increase the upper field of vision while tucked in extreme racing positions. In addition to innovative cooling properties, the surface area of the cheek pads has been enlarged by 16.5%, giving riders a more secure and comfortable fit, especially at high speeds.
CWR-F2R SHIELD & BASE PLATE SYSTEM
The all-new CWR-F2R 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 also offers a distortion-free view throughout the entire X-Fifteen eyeport.
Highlighting a long list of updates, the CWR-F2R 2D “flat” outside surface combined with 3D technology inside offers an aggressive look with optimized visibility for a more natural view. Vortex Generators on the sides of the shield improve aerodynamics and reduce wind noise, and an all-new center locking mechanism helps to evenly distribute shield forces across both spring-loaded base plates.
The X-Fifteen is equipped with an exclusive two-stage shield locking system [center locking mechanism plus racing shield lock], providing optimal protection against unexpected shield releases in the event of a fall. Additionally, a newly designed trigger lock mechanism, once activated, provides even more assurance by preventing the shield from detaching during an impact or crash.
