Redding, 20, has signed a two year agreement with Gresini Honda who are the first confirmed purchasers of the RCV1000R customer bike made available by Honda.
Redding will join fellow Britons Cal Cructhlow and Bradley Smith in the premier MotoGP class next year.
The deal puts Redding alongside Spanish rider Alvaro Bautista for 2014. Bautista will ride a factory prototype RC213V to complete the second year of a two-season deal.
If Redding fulfils the promise he has shown in Moto2 it is anticipated he will be promoted to a factory RC213V in 2015.
“I’ll be racing alongside the best riders in the world on the Honda RCV1000R so it is going to be a steep learning curve,” Redding said.
“This is why it was important to go with an experienced team like Gresini Honda.
“But my focus now is to win the Moto2 world championship for the Marc VDS Team without whose support I would never have been given to opportunity to move up to the premier class.”
Gresini Honda team boss, Fausto Gresini, is known for developing young talent and it was in his team that the late Marco Simoncelli emerged as a star before his tragic death at the Malaysian GP in 2011.
“I’m delighted to be able to work with a young latent like Scott with the aim of building an ambitious project aimed at taking him to the pinnacle of MotoGP,” Gresini said.
Redding is in a tense battle with Spanish young gun Pol Espargaro for the Moto2 title this season.
Espargaro will also move to MotoGP in 2014 without he Tech3 Yamaha team.
