Miguel Oliveira has been named as Jack Miller's successor in the Red Bull KTM Ajo Moto3 team after the Australian was confirmed as making the step to the premier MotoGP class in 2015.

Portuguese racer Oliveira is currently competing in his fourth season of the entry-level GP class aboard the Mahindra, the 19-year-old having notched up four podiums in that time and a best overall finish of sixth place in 2013.

Oliveira will make the switch to the leading Red Bull KTM Ajo for 2014 in place of Miller, the Australian - who currently leads the 2014 Moto3 standings - having been announced as moving to MotoGP aboard an Open-specification LCR Honda.

"I'm very happy to be joining as professional a group as Red Bull KTM Ajo and I think that this move will allow me to fight for the top positions next season," he said. "In the past Aki Ajo had demonstrated an interest in us working together, although we had never got as far as concluding an agreement. So I'm very happy to be riding as part of this structure, backed by a big factory like KTM and representing companies like Red Bull and the other big partners. It is an honour for me."

Team manager Aki Ajo is pleased to be welcoming Oliveira on board and is confident he will prove the ideal candidate to follow Miller's considerable success in the team.

"I'm very happy to start working with Miguel [Oliveira] from 2015, because we have known each other a long time and he is one of the biggest talents in this paddock. Even though he is still a young man, he has extensive experience in both 125cc and at the highest level in Moto3.

"Just as we have done in recent years with Red Bull, KTM and other partners, we will work to maintain the same level and get the best possible results; with Miguel I am sure that we have the potential to do so.

"As is normal, we have to think about the future and so we have moved to bring in Miguel, but at this point of the current season the most important thing is to keep our focus on the 2014 Moto3 World Championship. Now we are in a good position, but it's still a very tight series with many riders at the top."

There is no word on whether Miller's current team-mate, Red Bull Rookies champion Karel Hanika, will continue with the team in 2015.
