SHOEI · RF-1400 · Full Face
The SHOEI RF-1400 MS-06C-6 Zaku II is a full-face motorcycle helmet that pairs the RF-1400 platform with the distinctive Zaku II TC-4 colorway. Designed for high-performance riding, it’s well suited to street use and also rates strongly for race and touring, according to SHOEI’s riding-style scores.
Built around SHOEI’s Multi-Ply Matrix AIM+ shell and a Dual Density EPS liner, this helmet focuses on balanced airflow, aerodynamic stability, and wind-noise management. It uses the CWR-F2 shield system and includes a Pinlock® Evo Lens, plus a Breath Guard and Chin Curtain to help tailor comfort for everyday miles or higher-speed runs.
Construction
The RF-1400 uses a Multi-Ply Matrix AIM+ shell with a Dual Density EPS liner. It also incorporates SHOEI’s Emergency Quick Release System (E.Q.R.S.) to support cheek pad removal when needed. For riders comparing specs, the listed helmet weight is 3.64 pounds.
Shield
A CWR-F2 shield system is used on the RF-1400, featuring a 2D flat outside surface paired with 3D shaping inside for optimized visibility. SHOEI adds Vortex Generators on the shield sides to support aerodynamics and wind-noise reduction, plus a center locking mechanism designed to distribute forces across both spring-loaded base plates.
Comfort
Inside, the RF-1400 combines a Dual Density EPS with a 3D Max-Dry System II liner. SHOEI’s redesigned cheek pads add more volume at the bottom, aimed at comfort and reduced wind noise, and the lower cheek pad fabric is intended to feel soft while staying durable during regular use.
Ventilation
Ventilation on the RF-1400 was developed with SHOEI’s in-house wind tunnel, focusing on balancing airflow with a quieter ride. The center/forehead vent is repositioned and includes an added intake hole to help increase the volume of cooling air entering the helmet. At the rear, an enlarged exhaust outlet vent is designed to better use negative pressure suction to move warm air out.
Aerodynamics
The RF-1400’s shell shaping is engineered to move through the air efficiently, contributing to reduced wind noise while still allowing important road sounds to come through. SHOEI also incorporates Vortex Generators to help cut turbulence, along with airtight window beading intended to create a wind-resistant seal. Voluminous cheek pads and removable ear pads are designed to further suppress internal noise.
