Shoei RF-1400 Diggia Helmet

The latest flagship helmet from Shoei is here and they made sure not to skip a beat! An all new shell provides the lightest SNELL M2020 and DOT certified helmet Shoei has in the current offerings and the shell's shape helps better manage drag, lift and unwanted noise than its juggernaut predecessor, the RF-1200. The RF-1400 boasts an all new CWR-F2 baseplate and shield system that eases shield changes and features a new, easy to use locking mechanism in the center of each visor mounting side to evenly distribute pressure and seal your visor tight. A Pinlock EVO lens insert is included to clear your vision of fog and Shoei made sure to keep it cool with the moisture wicking 3D Max-Dry System II Liner and 3 adjustable air channels that vent from 6 different intakes while pushing hot air out through 4 exhaust vents in the back. All these features are a product of tireless R&D and wind tunnel testing to prove only the best will do with Shoei's latest and greatest RF-1400.

Design Concept

The wind tunnel tests have refined the RF's aerodynamics and ventilation to help evolve the design forward. Shoei managed to wring out the RF1200's aerodynamics with a 4% reduction in drag and 6% reduction in lift. The compact, aerodynamic shell shape is made to maximize ventilation as air flows over you while doubling as the lightest SNELL approved full-face helmet in Shoei's new offerings. No rider wants to forfeit important characteristics that most lighter helmets compromise on, such as wind noise. But the RF-1400, while being the lightest in the lineup, leaves no room for earache with its new noise reduction technology.


The shape of the spoilered shell was designed in a wind tunnel and through that testing, Shoei was able to provide a quieter shell design while also tweaking the shape of the all new CWR-F2 shield system using their Vortex Generator technology to displace wind turbulence. An all new, airtight window beading system provides a windproof and waterproof seal so tight, you'd think it was your turn to take a crack at opening the pickle jar. The RF-1400 also sports some more voluminous cheek pads and removable ear pads to help soften the "blow" of wind noise. 

Shell and EPS Liner Construction

Proprietary technology integrates a matrix of hand-laid interwoven layers of fiberglass and light-weight organic fibers to deliver a helmet that not only meets SNELL M2020 and DOT ratings, but is Shoei's strongest, most elastic shell providing the wearer with optimal impact absorption. Adding to that, the RF-1400 is lined with a dual layer of multi-density EPS foam liner that also aids in impact absorption and allows cool air to flow unrestricted through the channels created in the liner. The precise placement of the EPS material helped shape the RF-1400's compact, lightweight design.

Shield System

Shoei ditched the old baseplates from the RF-1200 and completely reworked the design to bring you the CWR-F2 base plate system. The system's main purpose is to facilitate quicker and smoother shield changes that are just as rewarding as the single "pop" of finally getting the lid off that pickle jar. The new shield adjuster mechanism is smoother and more precise than ever and a redesigned baseplate gear introduces an all-new "first position" shield opening feature for advanced venting and defogging. Shoei didn't stop there though! All new for the RF series is a conveniently located locking mechanism that distributes shield forces across both sides evenly.

The 3D injection molded CWR-F2 shield manages a distortion-free field of vision while protecting your eyes from 99% of the sun's harmful UV rays and the 2D "outside" surface combined with the 3D technology provides an aggressive look without compromising visibility. Pair it with the included, 10% wider Pinlock EVO to eliminate fog while also dismissing any woes for lateral visibility.


The RF-1400 is equipped with a fully removable, washable, replaceable and adjustable interior made from Max-Dry materials to absorb and dissipate sweat two times quicker than traditional nylon. The cheek pad fabric is soft and durable to provide comfort and a plush fit and the voluminous pad material is multi-layered for improved stabilization and keeps decibels down in the helmet. Customize your fit with the optional interior components offered in different sizes.

Ventilation Performance

Pardon us for being a bit long winded here, but we want you to know just how great this helmet is. Let's direct that wind a bit more. The ventilation system has 3 channels to manipulate 6 entryways of air for your comfort: 2 in the center, 2 in the chin bin and 1 on each side of the temples. The relocated center/forehead vent offers an additional air vent hole compared to its predecessor, while the side vents are larger for greater air intake as well. The large, no-fuss 3 position lower vent shutter is easy to use with gloves on while riding and the RF-1400 has a redesigned enlarged exhaust vent with 4 outlets to push the hot air out while getting in all that sweet, cool air.


Shoei once again has found the right recipe to bring a spectacular helmet at a fair price on the market. The RF-1400 offers more than what most riders seek in a helmet and this latest offering of the flagship presents a wonderful melting pot of a timeless design, aerodynamic performance, ventilation, quietness, ease of use, comfortability and an utmost quality in build, materials and manufacturing that only a Shoei can provide.
