An ensemble of refined details. Such words are appropriate for the FF-5. OGK KABUTO has previously made active efforts to develop ventilations which take into account aerodynamics, and the FF-5 can be regarded as the present culmination of this work.
  The major difference from conventional products is a form which smoothes the surface to the greatest possible extent. Each air duct has a form which is built into the helmet body, and is finished into a design which makes the outstanding aerodynamics evident even to the eye. The form of the air ducts themselves is also significantly different than them. In developing the FF-5, OGK KABUTO Helmet newly designed all of its parts. For that reason, there are almost no parts in common between the FF-5 and conventional models.
  The ventilation form for the head part which includes a newly developed Wake Stabilizer, new Top Aero-Ventilation to always keep the inside of the helmet comfortable with outstanding air flow, and Single Action Shield System which enables shield mounting/removal with a single touch. These forms were all logically derived as a result of wind tunnel experiments.
   A thorough review of the role and form of ducts was conducted from the initial stage of development by inviting specialists in aerodynamics as advisors. Once a prototype was finished, it was repeatedly tested, and then evolved further based on the obtained data. The impeccable aeroform you see was finished through an exhaustive development process based on trial and error.
