That means with the return of Suzuki and now Aprilia, the 2015 MotoGP grid will consists of five “Factory” manufacturers – the latter two along with Ducati, Honda and Yamaha.Aprilia Racing has signed a contract with Gresini Racing, which will run the prototypes through 2018. As for riders, no one has been assigned yet. But Marco Melandri, the 2002 250cc MotoGP Champion (Aprilia machinery), is helping develop the prototype. Melandri is currently piloting an RSV4 for Arpilia Racing in World Superbike.“We decided to make our debut a year earlier than planned because Aprilia Racing’s technical and competitive skills are absolutely top notch” says Piaggio Group’s Chairman and CEO, Roberto Colaninno. Growth in Superbike has been exemplary in this direction from our rookie year in 2009 to the five world titles we’ve won so far with the RSV4.”“Piaggio Group has been managing Aprilia since 2005, and in less than ten years Aprilia won 26 of the 52 world titles earned in the entire brand history. In addition to these there are also four more titles: Marco Simoncelli’s 250 world championship with Gilera and three 125 class world championships won by Derbi, which is also part of the Piaggio Group and which took a very young Marc Marquez to his first world title win.”The manager of Gresini Racing, two-time 125cc Champion Fausto Gresini, also commented: “I am very glad that Aprilia identified Gresini Racing as the ideal partner to enter the MotoGP World Championship: I would like to thank the Piaggio Group for giving me a fantastic opportunity, that is working closely with such a glorious manufacturer; an Italian brand that has become a synonymous of passion for racing, reaching amazing results worldwide.“The four years agreement between Gresini Racing and Aprilia opens a new chapter in our history: in this moment I feel a great responsibility, but the motivation to succeed in this exciting, all Italian challenge is even bigger.“The Grand Prix world is part of the Aprilia brand and to represent it in the premier class, the MotoGP World Championship, is a source of great pride for all of us. An incredible reward for the work done in all these years by Gresini Racing”.Aprilia Racing & Gresini Racing History (courtesy of Aprilia Racing & Gresini Racing)The Aprilia trophy case currently includes 294 wins and 38 championship titles in the Grand Prix motorcycle racing championship (19 Manufacturer and 19 Rider), 45 wins and 5 world titles in WSBK (three manufacturer and two rider) and nine world championships in off road disciplines.Many recent protagonists in the motorcycle racing world have raced, won and been educated astride Aprilia bikes such as Max Biaggi, Loris Capirossi, Valentino Rossi, Marco Melandri, Manuel Poggiali, Jorge Lorenzo and Casey Stoner.
