AGV Skyline Block Helmet Drawing heavily on the technology developed in MotoGP for the AGV GP-Tech helmet, the Skyline brings this technology to a touring helmet for the first time. The Skyline incorporates a number of specific features that makes riding on the road a much more pleasurable experience.
