Shoei RF-1400 Helmet - Special Designs

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, we pushed our resources and technologies to the brink, utilizing our 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 spoiler
• Strategically-shaped air intake and exhaust vents help streamline the overall profile
• Lift 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 turbulence
• 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 expulsion
• 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 aggressive 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 spoiler 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 System

• 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

Shoei GTA-Air-II and RF-1400 are both motorcycle helmets from the Japanese brand Shoei, but they have some differences in terms of design, features, and intended use.

Here are some of the key differences between the two models:

1. Design: The GTA-Air-II has a more aerodynamic shape with a larger rear spoiler than the RF-1400. The GTA-Air-II also has a wider face shield for better peripheral vision.

2. Ventilation: Both helmets have a similar ventilation system, but the GTA-Air-II has more ventilation channels, including a rear exhaust vent, which may provide better airflow.

3. Weight: The RF-1400 is slightly lighter than the GTA-Air-II, weighing around 3.5 pounds, while the GTA-Air-II weighs around 3.7 pounds.

4. Noise Reduction: The RF-1400 has a more effective noise-reduction system, including a chin curtain and ear pads, which may make it a better choice for long rides.

5. Certification: Both helmets meet or exceed DOT and SNELL safety standards, but the RF-1400 also meets the stricter ECE 22.05 standard, making it legal for use in Europe.

6. Price: The RF-1400 is generally less expensive than the GTA-Air-II.

In summary, the GTA-Air-II is designed to be more aerodynamic and may have better ventilation, while the RF-1400 is designed to provide better noise reduction and meets additional safety certifications. The choice between the two models will depend on the rider's personal preferences and intended use.
