Shoei RF-1400 MM93 American Spirit Helmet

The Evolution of Perfection is a fitting tagline for the longest-standing, most decorated full-face helmet model in the Shoei lineup, the RF. The process of improving is a constant evolution, and with a world-class team of designers and engineers leading the charge, SHOEI pushed their resources and technologies to the brink, utilizing a state-of-the-art wind tunnel facility, extensive array of proprietary materials, and the industry's most stringent quality assurance practices to develop the all-new RF-1400. SHOEI's lightest and most compact SNELL-approved full-face helmet model, the RF-1400 has evolved the pursuit of perfection to the next level. 

Aerodynamics

• Developed and refined in SHOEI's state-of-the-art wind tunnel facility 
• Compact, aerodynamic shell shape with integrated spolier 
• Strategically-shaped air intake and exhaust vents help streamline the overall profile 
• Life Reduction (upward lift forces): -6% 
• Drag reduction (forward drag forces): -4% 

Advanced Noise Reduction

• Optimal Shell aerodynamics reduce wind noise around the helmet 
• Vortex Generators on the sides of the shield reduce wind turbulance 
• All-new airtight window beading provides wind/waterproof seal 
• New, voluminous cheek pads and removable ear pads further restrain wind noise inside the helmet 
• The RF-1400 provides an incredibly quiet riding experience without blocking the road's informative sounds 

Ventilation

• Wind tunnel-optimized to provide the perfect balance between airflow and silence 
• Relocated center/forehead vent is equipped with an additional air intake hole for greater airflow into the helmet 
• Upper air intake holes have been enlarged for optimal performance 
• New, enlarged exhaust outlet vent for improved hot-air explusion 
• Large 3-position lower vent shutter for ease of use with riding gloves 
• Features six (6) air intake vents and four (4) exhaust outlets 

CWR-F2 Shield

• Protects from 99% of the sun's damaging UV rays 
• 3D injection-molding ensures distortion-free view throughout the entire field of vision
• 2D "flat" outside surface combined with 3D technology inside offers an aggresive look with optimized visibility 
• Vortex Generators improve shield aerodynamics and reduce wind noise 
• All-new, conveniently located center locking mechanism evenly distributes shield forces across both base plates 
• PINLOCK EVO fog-resistant system is 10% larger for improved lateral vision 

CWR-F2 Base Plate

• Completely redesigned to facilitate quicker, smoother shield changes 
• New Shield adjuster mechanism provides easier, more precise tuning
• Redesigned base plate gear has all-new "first-position" shield opening feature for advanced venting and defogging 
• SHOEI's patented spring-loaded technology ensures a wind and waterproof seal 
• All-new airtight window beading reduces wind and water intrusion 

Multi-Ply Matric Aim+ Shell

• Proprietary technology integrates a multi-ply matrix specifically designed to meet both SNELL M2020 and DOT standards
• Hand-laid interwoven layers of fiberglass with lightweight organic and high-performance fibers 
• Shell-integrated spolier with consistent shell thickness guarantees proper strength and weight 
• SHOEI's strongest, lightest, most elastic shell provides optimal impact absorption 

Dual-layer /Multi-Density EPS Liner

• Provides enhanced impact absorption by utilizing varying densities of foam 
• Allows cooling air to travel unrestricted through tunnels created in the EPS 
• Precise placement of multi-density EPS material yields a more compact, lightweight design 

Emergency Quick Release

• Allows emergency medical personnel to easily and safely remove the cheek pads from an injured rider's helmet

3D Max-Dry Interior System II

• Fully Removable, washable, replaceable and adjustable 
• Exclusive Max-Dry material absorbs and dissipates sweat 2X faster than traditional nylon interiors 
• Soft yet durable lower cheek pad fabric for a plush fit and feel 
• Three dimensionally shaped to match the contours of a rider's head
• Multi-layer cheek pads for improved comfort and helmet stabilization 
• Cheek pads feature more volume for greater comfort and reduced wind noise
