Shoei X-15 Diggia 2 Full Face Racing Helmet
A pure racing helmet boasting optimal performance, functionality, and safety, the X-15 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-15 is a high-performance work of art that possesses incredible advancements in aerodynamics, ventilation, vision, comfort, and adjustability.
TECH SPECS:
AERODYNAMIC PERFORMANCE
Among the most important and widely studied properties in racing, no stone was left unturned during the development of the X-15’s aerodynamics. Designed and refined in SHOEI’s state-of-the-art wind tunnel facility, the X-15 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-15’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 eye-port.
- Increased upper field of vision by 5mm
- Racing positiion
- Optimized eyeport trajectory
- Wider peripheral vision
- 10% larger pinlock® evo lens
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
- Exclusive two-stage shield locking system features a center locking mechanism and racing shield lock
- Two-stage system provides optimal protection against unexpected shield releases in the event of a fall
- New trigger lock mechanism [once activated] provides additional assurance by preventing shield detachments during an impact
- Center locking mechanism helps to evenly distribute shield forces across both spring-loaded base plates
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
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
