AGV K3 Helmet The K-3 is near the top end of the AGV entry level range. GP-tech lines and Valentino Rossi replica helmet graphics make this the ideal helmet for young riders and fans of the racing world. The only full-face thermoplastic model in the agv range, the K-3 is the perfect choice for riders in search of a safe, high-quality helmet with attractive design at a modest price.The K-3 design is inspired by the latest AGV developments starting from the Stealth, S-4, and Ti-Tech and continuing with the Blade/Blade LX and GP-Tech that have so clearly and distinctive defined the companys style. This makes the helmets immediately recognizable and distinguished from all the other proposals on the market. In the same way, the differences with the helmet that the K-3 has replaced are equally evident.

I have a head that measures 56.5 in circumference, which puts me directly between small and medium in many size charts. I love the looks of this lid and 4-star Sharp rating was a plus for me. I ordered a Medium, which I thought would be a comfortable fit for me. No luck. I could put my fingers between the front liner and my head, I could turn my head in the helmet. Which meant that this helmet was more oval than my head is. I exchanged it with a small. Too tight. Be ware buyer. This helmet, despite its high standards, has a very thin and scratchy liner in it. If you want a secure, snug fit, but a plushy feel, this one is NOT for you. Had to return two sizes already, and don't know what to do now. Perhaps a Scorpion. Nevertheless, Revzilla has the best customer service I've ever tested. Kudos to them for standing behind their promises.
