16-year-old Australian Arthur Sissis has signed to race for the factory-KTM backed Ajo Motorsport Team in the 2012 Moto3 World Championship.
Sissis will ride alongside fellow ex-Red Bull Rookie star Danny Kent, who raced for the Red Bull Ajo Aprilia team in this year's 125cc World Championship.
“It's a dream come true,” said Sissis, who finished second in the 2011 Rookie Cup behind Lorenzo Baldassarri. “This has been the best year of my life. I have learnt so much in the Rookies Cup.
"I was a speedway rider before and learnt everything about road racing in the Cup. I know that racing in the GP class is a new challenge but I'm ready for it.”
Sissis rode from 30th on the grid to 20th on his 125GP debut for TT Motions Aprilia in the penultimate round of this season at Sepang.
Kent finished eleventh overall in his first full year of grand prix, taking a best race finish of fourth.
15-year-old Italian Baldassarri is too young to race in GPs and will stay in the Rookies Cup for 2012.
