・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 arranged to face the optimal direction for the helmet's angle during riding, based on wind tunnel tests and CFD analysis.
・Achieves impactful coolness where you can feel the wind even at low speeds.
・(Left) Wind tunnel tests confirmed that coolness can be felt in about 30 seconds from the start of riding.
・(Right) The newly designed chin ventilation, developed by determining the optimal combination based on the results of pre-assuming and verifying numerous patterns for the number, position, angle, and shape of the ventilations, divides the air intake into two directions: upwards to reduce shield fogging, and directly towards the mouth to introduce air, 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 inside of the helmet and the head, optimizing the thickness distribution of the interior, and varying the thickness of most of the fabric through hot pressing, a new sensation of seamless fitting with fewer seams is achieved, allowing you to experience the coolness of air passing through.
【Antimicrobial Interior】
Used in some parts
・The inner pad part adopts DEOFACTOR's "antimicrobial processing" which suppresses the growth of bacteria on fibers. DEOFACTOR decomposes harmful substances adhering to clothing and textile products through its antimicrobial action.
DEOFACTOR is a special processing technology developed by KOKORO CARE.
【"UV & IR Cut Shield" using Teijin Limited's heat-shielding material】

・Adopts "UV & IR Cut Shield" which uses Teijin Limited's high-performance polycarbonate as the shield material to cut UV (ultraviolet rays) and IR (infrared rays).
・It has heat-shielding performance that suppresses temperature rise due to solar radiation heat generated by infrared rays (IR), and reduces heat transfer to the inside of the helmet while maintaining "clear visibility," which is the most important aspect for helmet shields.
Temperature inside the helmet measured in-house by irradiating with an incandescent lamp (300W)
【Dedicated mounting space for intercom installation】

・Dedicated mounting spaces are pre-set on the left and right, considering intercoms and cameras.
・Cable routes are also installed, enabling smart wiring for cords from speakers, etc.
Some special shapes cannot be installed.
【Pinlock Original Insert Lens Installable】

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

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

・Adopting effective parts layout and shell design for a stylish & compact look.
【Glasses-compatible cheek pads】

・The cheek pad shape, which adopts a new sewing pattern, allows for smoother attachment of glasses 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巻き込み from around the chin during riding.
・Can be attached and detached 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 attachment/detachment and fine adjustment.
・Multiple engagements ensure reliable operation and safety.
【T.P.S. (High-performance thermoplastic cap body)】

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

・Achieves fine fitting by adopting two cap bodies.
【Micro Ratchet Buckle】

・A chin strap retention device that allows one-touch attachment/detachment.
・Fine adjustment is easy with the fine ratchet.
