Stefan Bradl will step up to grand prix racing's premier class in 2012 after signing a two-year deal with the LCR Honda squad.
The 21-year-old German, who won the Moto2 title this year, tested an 800cc RC212V for Lucio Cecchinello's team at Valencia last week.
He has now confirmed that he will race one of the manufacturer's new 1000cc RC213Vs in next year's championship.
"This is simply fantastic like a dream that comes true," said Bradl.
"When I tested the RC212V in Valencia I realised that LCR Team is very professional and well organised, so I am sure they will do their best to support me.
"Making my debut in the premier class aboard the RC213V is great and I can not wait to get back on track."
Checcinello, whose team will run Honda machinery for a seventh straight year, is hopeful that Bradl's signing can return the outfit to the glory days of 2006, when it took podium finishes and a pole position with Casey Stoner.
"Together with Honda we have considered several riders and Stefan was one of our candidates," he said.
"After the test in Valencia we were very impressed by his potential and his determination: Stefan is young and fast and he just clinched the Moto2 world title, so we believe we can grow together with the team in the next two years.
"He already knew the technical staff and today I am happy to give him our warmest welcome in the LCR Team."
