・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 optimally positioned to align with 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 have proven that coolness can be felt within approximately 30 seconds of starting to ride.
・(Right) The newly designed chin ventilation, developed by anticipating and verifying numerous patterns for the number, position, angle, and shape of vents, divides the air intake into two paths: one directed upwards to reduce shield fogging, and one directed forwards to directly deliver air to the mouth, achieving unprecedented coolness.
The rear ventilation does not have an opening/closing function.
【Interior (HEXA-PAD) with a new fitting sensation that allows air to pass through】

・By analyzing the space between the helmet interior and the head to optimize the interior padding thickness distribution, and by using hot press processing to vary the thickness of most of the fabric, a new seamless fitting sensation with fewer seams is achieved, allowing you to experience the coolness of air passing through.
【Antimicrobial Processed Interior】
Partially used
・The inner pad uses DEOFACTOR's "antimicrobial processing" which suppresses the growth of bacteria on fibers. DEOFACTOR decomposes harmful substances attached to clothing and textile products through its antimicrobial action.
DEOFACTOR is a special processing technology developed by KOKORO CARE.
【Uses Teijin Limited's heat-shielding material "UV & IR Cut Shield"】

・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 caused by solar infrared (IR) radiation, reducing heat transfer to the helmet interior while maintaining "clear visibility," which is the most important factor for helmet shields.
In-house measurements of helmet interior temperature when irradiated with an incandescent lamp (300W)
【Dedicated mounting space for intercoms】

・Dedicated mounting spaces for intercoms and cameras are pre-set on both the left and right sides.
・Cable routes are also provided, allowing for neat wiring of cords from speakers and other devices.
Some uniquely shaped devices may not be installable.
【Pinlock Original Insert Lens compatible】

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

・A coverless shield replacement system that enables quick shield changes.
【Wake Stabilizer PAT.】

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

・Achieves a stylish and compact design by effectively arranging parts and adopting a suitable shell design.
【Eyeglasses-compatible Cheek Pads】

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

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

・Adopts a newly designed breath guard that expands the area of air blown onto the inside of the shield.
・Contributes to defogging the shield.
【Micro Ratchet Buckle】

・Uses a micro ratchet buckle that allows for one-touch detachment and fine adjustment.
・Multiple interlocking teeth 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 using two shell sizes.
【Micro Ratchet Buckle】

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