Shoei X-Fifteen Escalate TC-4 Helmet

A pure racing helmet boasting optimal performance, functionality and safety, the X-Fifteen is the latest generation of SHOEI's most technologically advanced sport and competition model. The X-Series has earned the praise of the world's top racers, including 8-time World Champion Marc Marquez. Incorporating valuable data learned through years of international race wins, the X-Fifteen is a high-performance work of art that possesses incredible advancements in aerodynamics, ventilation, vision, comfort and adjustability.

FEATURES:

• Developed utilizing rider input from the world’s top racers
• Refined in SHOEI’s wind tunnel to achieve next-level aerodynamics and ventilation
• Boasts impressive reductions in lift and drag along with enhanced high-speed stability
• Improved cheek pad cooling system and increased cool-air ventilation throughout the entire helmet
• Optimized eyeport trajectory for an increased upper field of vision
• Independently adjustable interior components for a precision racing fit

AERODYNAMIC PERFORMANCE

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

RACING VENTILATION

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.

• Features seven (7) closable air intakes and six (6) exhaust outlets—all strategically shaped and located to maximize airflow and negative air pressure suction
• Enlarged EPS tunnels (from 6mm to 10mm in depth) dramatically increase cool-air volume and the rate of hot-air expulsion
• Significant improvements to the cheek pad cooling system help deliver refreshing air and clear humidity from the rider’s face with even greater efficiency
• Wind tunnel optimized to excel in the tucked racing position, even behind windscreens

RACING 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.

SHIELD & BASEPLATE SYSTEM

• Protects from 99% of the sun’s damaging UV rays
• Distortion-free view throughout the entire X-Fifteen eyeport
• “Flat” outside surface (for racing tearoffs) combined with 3D technology inside offers an aggressive look with optimized visibility
• Vortex Generators on the sides of the shield improve aerodynamics and reduce wind noise
• Redesigned base plate system enables smoother shield openings and closures
• SHOEI’s patented spring-loaded technology ensures a wind and waterproof seal
• Latest generation window beading prevents wind and water intrusion when the shield is locked

TWO-STAGE SHIELD LOCKING SYSTEM

• Protects from 99% of the sun’s damaging UV rays
• Distortion-free view throughout the entire X-Fifteen eyeport
• “Flat” outside surface (for racing tearoffs) combined with 3D technology inside offers an aggressive look with optimized visibility
• Vortex Generators on the sides of the shield improve aerodynamics and reduce wind noise
• Redesigned base plate system enables smoother shield openings and closures
• SHOEI’s patented spring-loaded technology ensures a wind and waterproof seal
• Latest generation window beading prevents wind and water intrusion when the shield is locked

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.

MULTI-PLY MATRIX AIM+ SHELL

• Proprietary technology integrates a six-ply matrix
• Hand-laid interwoven layers of fiberglass with lightweight organic and high-performance fibers
• Provides optimal impact-absorption, strength and elasticity
• Snell M2020R and ECE22.06 certified

MULTI-PIECE/MULTI-DENSITY EPS LINER

• Provides optimized impact absorption by utilizing varying densities of foam in key areas around the head
• Precise placement of multi-density EPS material yields a more compact, lightweight design
• Features strategically located tunnels that allow cooling air to travel unrestricted through the helmet
• Enlarged EPS tunnels (from 6mm to 10mm in depth) dramatically increase cool-air volume and the rate of hot-air expulsion

EMERGENCY QUICK RELEASE SYSTEM (E.Q.R.S.)

• Allows emergency medical personnel to easily and safely remove the cheek pads from an injured rider’s helmet
• Helmet can be gently removed from an injured rider’s head with minimal load placed on his/her neck

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.

3D MAX-DRY CUSTOM INTERIOR SYSTEM II

• Fully removable, washable, adjustable and replaceable
• Exclusive 3D Max-Dry material absorbs and dissipates sweat twice as fast as traditional nylon
• Innovative cheek pad cooling system delivers refreshing air to the rider’s face
• Cheek pad surface area enlarged by 16.5%, giving riders a more secure and comfortable fit, especially at high speeds

PRECISION FIT

• Independently adjustable 3D center pad components can be replaced with optional thicknesses for a customizable fit
• All-new pocket-shaped pads have separate, removable layers that can be peeled away to further optimize a precision fit
• Patented angle adjustment mechanism changes helmet position up to 4 degrees to increase upper field of vision while tucked in extreme racing positions
