・Standard: JIS
Features:
【Ultra Cooling System】

・A newly designed cooling system that allows you to feel the wind from the moment you start riding.
・Ventilation holes are positioned at an optimal angle for helmet orientation during riding, based on wind tunnel experiments and CFD analysis.
・Achieves impactful coolness where you can feel the wind even at low speeds.
・(Left) Wind tunnel experiments have demonstrated that coolness can be felt within approximately 30 seconds of starting to ride.
・(Right) The newly designed chin ventilation, developed based on the results of pre-assuming and verifying numerous patterns for the number, position, angle, and shape of ventilations, divides the incoming air into two directions: upwards to reduce shield fogging, and forwards to directly bring air to the mouth, achieving unprecedented coolness.
The rear ventilation does not have an opening/closing function.
【Interior with a new sensation of fitting that allows air to pass through (HEXA-PAD)】

・By digitizing the space between the helmet interior and the head, optimizing the interior thickness distribution, and varying the thickness of most of the fabric through hot press processing, a new sensation of seamless fitting with fewer seams is achieved, allowing you to experience the coolness of air passing through.
【Antibacterial Interior 】
Partially used
・DEOFACTOR's "antibacterial treatment" is adopted for the inner pad part, which suppresses the growth of bacteria on fibers. DEOFACTOR decomposes harmful substances adhering to clothing and textile products through its antibacterial action.
DEOFACTOR is a special processing technology developed by KOKORO CARE.
【Teijin Limited Heat Shielding Material "UV & IR Cut Shield" Adopted】

・Adopts "UV & IR Cut Shield," which uses Teijin Limited's high-performance polycarbonate as the shield material to cut UV (ultraviolet) and IR (infrared) rays.
・It has heat shielding performance that suppresses temperature rise due to solar infrared (IR) radiation, reducing heat conduction to the helmet interior while maintaining "clear visibility," which is the most important factor for helmet shields.
Measured internal helmet temperature by irradiating an incandescent lamp (300W) in-house.
【Dedicated Mounting Space for Intercom Installation】

・Dedicated mounting spaces for intercoms and cameras are pre-set on both sides.
・Cable routes are also simultaneously installed, allowing for smart wiring of cords from speakers and other devices.
Some special shapes cannot be installed.
【Pinlock Original Insert Lens Mountable】

・Can be equipped with a 100% MAX VISION Pinlock sheet (sold separately) that covers up to the upper edge of the shield.
【CF-1 Shield System】

・A coverless shield replacement system that allows for quick shield replacement.
【Wake Stabilizer PAT.】

・Kabuto's patented system that controls airflow near the helmet shell and reduces load.
【Stylish Compact Design】

・Stylish and compact design achieved through effective part layout and shell design.
【Eyeglass-compatible Cheek Pads】

・The cheek pad shape, which adopts a new sewing pattern, allows for smoother wearing of eyeglasses and sunglasses.
There are individual differences depending on the shape of the glasses and the shape of the face.
【Wind Shutter No.7】

・Reduces wind ingress from around the chin during riding.
・Can be detached and attached as desired depending on the season and use.
【Breath Guard No.9】

・Adopts a newly designed breath guard that expands the blowout area to the back of the shield.
・Contributes to removing shield fogging.
【Micro Ratchet Buckle】

・Adopts a micro ratchet buckle that allows one-touch detachment and fine adjustment.
・Multiple engagements ensure reliable operation and safety.
【T.P.S. (High-Performance Thermoplastic Shell)】

・A thermoplastic helmet shell made of high-performance resin raw material with excellent impact resistance.
【2-Shell】

・Achieves fine fitting by adopting two shell sizes.
【Micro Ratchet Buckle】

・A chin strap retention device that allows one-touch detachment.
・Fine adjustments are easy with the fine ratchet.
