I have been riding for 17 years now and have had a variety of helmets. I bought my first Arai, a Giga 2, back in '94. Once I had one nothing compared. Four years later the Giga was damaged but I could not afford another one so a cheap replacement was bought until I could afford another. May this year I visited my local bike shop and spotted the Signet GT on the shelf, it is quite distinctive owing to its array of vents and slightly pointed front. I asked to try it on and immediately wanted it! For my head the Signet was a perfect fit in all respects so I walked out the shop the owner of a new Signet GT! It was first worn by myself on a track day at Mallory Park, slipping it on it felt comfortable straight away, fastening is by the easy method of two D rings. I trundled off on this hot day and then remembered its array of vents,there are five in total,four on top and one in the chin bar. These are all easily operated even with gloved hands, 3 seconds later I had a very noticeable influx of cool air around my head.The visor is fitted/removed using Arai's Adsis system so only takes a few seconds to change. The finish is second to none, mine being a metallic black example. Knowing from past experience the quality of Arai, I know I am going to have years of service from this one and should the worst happen I know I have the best protection to give me a better chance of surviving.
