Thomas Morsellino is a French freelance journalist and photographer, with keen eye for the technical details of MotoGP bikes. You may have seen some of his work on Twitter, where he runs the @Off_Bikes account. After every race, MotoMatters.com will be publishing a selection of Tom's photos of MotoGP bikes, together with extensive technical explanations of the details by Peter Bom. MotoMatters.com subscribers will get access to the full resolution photos, which they can download and study in detail, and all of Peter's technical explanations of the photos. Readers who do not support the site will be limited to the 800x600 resolution photos, and an explanation of two photos.
