Sizes are for reference only.
Due to product design, the fit may vary even with the same size indication.
・Standard: JIS
Features:
【Ultra Cooling System】

・A newly designed cooling system that allows you to feel the wind the moment you start riding.
・Ventilation holes are positioned at an optimal angle for the helmet's attitude during riding, determined through 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 you can experience coolness within about 30 seconds of starting to ride.
・(Right) The newly designed chin ventilation, developed by determining the optimal combination based on the results of pre-assuming and verifying multiple patterns for the number, position, angle, and shape of the ventilations, divides the air intake into two streams: upward to reduce shield fogging, and forward to directly introduce air to the mouth area, achieving unprecedented coolness.
Rear ventilation does not have an opening/closing function.
【Interior with a new sensation of fitting where wind flows through (HEXA-PAD)】

・By optimizing the thickness distribution of the interior by converting the space between the inside of the helmet and the head into data, and by varying the thickness of most of the fabric through hot pressing, a seamless fit with a new sensation and fewer seams is achieved, allowing you to experience the coolness of wind flowing through.
【Anti-bacterial Interior】
Used in some parts
・The inner pad uses DEOFACTOR's "anti-bacterial processing" which suppresses the growth of bacteria on fibers. DEOFACTOR decomposes harmful substances adhering to clothing and textile products through its anti-bacterial action.
DEOFACTOR is a special processing technology developed by KOKORO CARE.
【Teijin Limited Heat Shielding Material "UV & IR Cut Shield" Adopted】

・Adopts a "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 heat generated by infrared (IR) rays, and reduces heat transfer to the inside of the helmet while maintaining "clear visibility," which is the most important aspect for a helmet shield.
Internal measurement of helmet temperature by irradiating an incandescent lamp (300W).
【Dedicated installation space for intercoms considered】

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

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

・Coverless shield replacement system that enables 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 due to effective part layout and shell design.
【Eyeglass-friendly Cheek Pads】

・The cheek pad shape, which adopts a new sewing pattern, allows 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巻き込み (wind entanglement) 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 the removal of 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 shell made from high-performance resin raw materials with excellent impact resistance.
【2-Shell】

・Achieves precise fitting by adopting two shell sizes.
【Micro-ratchet Buckle】

・A chin strap retention device that can be detached with one touch.
・Fine adjustments are easy with the fine ratchet.
