The SHOEI RF-1400 Black Ti-Star's Zaku II High Mobility Type helmet is a tribute to the legendary Black Tri-Stars of Zeon, the ruthless trio of pilots known for their precision and unparalleled skills in the Mobile Suit Gundam universe. This helmet combines cutting-edge performance and protection with the unmistakable graphic of the Black Tri-Stars' iconic Zaku II High Mobility Type, a mobile suit renowned for its versatility and strength. With SHOEI's Multi-Ply Matrix AIM+ shell, you get a lightweight yet durable structure that provides maximum impact protection. The aerodynamic design is engineered to reduce drag and lift, keeping you stable at high speeds. A CWR-F2 shield with Pinlock(R) lens ensures clear, fog-free vision, while the Max-Dry interior system rapidly absorbs moisture to keep you comfortable on long rides.

The Shoei RF-1400 builds on the rich history of their RF line of full-face helmets. The bullet points above go over the performance enhancements for this evolution but I wanted to point out some of the big changes. On first look you see that Shoei has completely updated the front air intakes for this helmet. The main forehead vent now has two intakes instead of one and operates by sliding the cover up instead of the small switch on the RF-1200 that moved laterally (and was sometimes hard to find in gloves). This cover holds in place partially open to allow for a smaller amount of air intake than when fully open. The chin vent is also redesigned to make room for the new center locking mechanism on the visor. This new center lock will keep the visor closed at high speeds but is still simple to operate even in gloves.
The visor itself has a new addition of vortex generators near the trailing edges which help to reduce wind noise at high speed and improve the aerodynamic efficiency of the helmet. The Pinlock pins have been moved further out of view to remove them from your field of vision. By widening the visor to move the pins they had to redesign the baseplate kit to fit into a smaller space. The new baseplate has more detent options including a new first position that is optimal for shield defogging. Take a close look at the baseplate and you will see a shield adjustment lever. Changing the position of this lever moves the baseplate ever so slightly and allows you to get a tighter closure between the visor and the gasket around the eyeport.
The rear exhaust ports are no longer adjustable, but they are in a more streamlined position which will improve the vacuum effect used to pull air through the air intakes. At the rear of the helmet we also see more pronounced grooves that channel air flow to help with this effect and the overall aerodynamics of the helmet.
The cheek pads have been redesigned to maximize comfort and reduce wind noise. They do still have channels for eyeglasses as well.
The RF-1400 will come in 4 shell sizes (XS-S, Medium, Large, XL-XXL) initially with a 5th shell size (3XL) being introduced in mid-2021 that will most likely only be available in a few of the solid colorway options. Initially there will be 6 solid color options to go along with 7 different graphics. – Mike 12/22/2020
