Yamaha have confirmed that reigning 250cc world champion Jorge Lorenzo will ride for them in MotoGP in 2008.
The Spanish rider has been linked to securing a ride with the manufacturer for a long time, although Yamaha did not announce if he would partner Valentino Rossi in the same team.
A statement from Yamaha said: "Jorge Lorenzo will make his MotoGP debut in 2008 aboard a YZR-M1, with direct factory support.
"The exact structure of Yamaha's team and rider organisation is still under consideration at the present time. Further details, including Lorenzo's team structure, will be announced in due course."
Lorenzo is currently leading the 250cc championship riding an Aprilia, although Yamaha have made no secret of their interest in the 20-year-old.
"Yamaha has been watching Jorge's career with interest for some time and we are delighted that he will be joining our MotoGP line-up from next season," said Lin Jarvis, managing director of Yamaha Motor Racing.
"We are sure that he will be a valuable asset for the future and we look forward to the commencement of his MotoGP career with Yamaha."
Lorenzo has signed a two-year-deal with Yamaha, and one possible team structure could involve the Spaniard racing in a factory-supported one bike team.
