The Arai RX-7 GP is the most extensive race tested helmet ever. This successor to the legendary RX-7 Corsair, has been developed in actual Moto GP and Grand Prix races. Tested at high speeds on the straights of international racetracks. Designed for and used by winning professional riders. The result is the stunning new RX-7 GP with an adjustable Air Wing that significantly reduces buffeting and drag when the riders emerge from a full tuck when braking from high speeds, enhancing concentration. At the same time the Air Wing increases the top speed thanks to the improved aerodynamic properties of the new RX-7 GP.  This helmet is an Arai Size Large which I received at Laguna Seca years ago.  There are two very small marks on the helmet which are shown in photo 6 .  In addition, the left top vent shutter stays open.  Other than that it has very slight micro scratches from use, which cannot even been seen in my high resolution and detailed photo's.  I treat all my helmets with "Plexus" on the outside and use a cleaner on the inside after every ride.  This helmet has not been used in several years and is very, very hard to find an Arai Moto GP Helmet!  In the last four years I have never seen one here on ebay. You can contact me if you have any questions. *Its never been on an accident or fall Size Large  71/4 - 73/8  ( 59-60 cm
