Scottish teenager John McPhee is to replace injured Frenchman Alexis Masbou for the remaining five rounds of the Moto3 World Championship, starting this weekend in Aragon.
Caretta Technology rider Masbou, who is currently sixth in the world championship, broke his femur in a private test at Vallelunga earlier this month.
18-year-old McPhee will join the Turin-based Caretta squad at Aragon and will compete on his KRP M3-01 chassis which has been re-liveried in Caretta Technology colours and is to be fitted with the Italian squad's Geo Technology grand prix spec Honda engine.
McPhee, whose regular ride is with the Racing Steps Foundation-backed KRP team in Spain's CEV Moto3 Series, will wrap up his hectic end-of-season schedule with a return visit to Valencia for the final round of the Spanish Championship.
"It's fantastic to be given the opportunity,” said McPhee. “To get more experience at world level with a grand prix team like Caretta should give a boost to my prospects of getting a full-time World Championship ride in 2013.
“Naturally I have a lot of sympathy for Alexis and wish him all the best for a speedy recovery. He's clearly had a strong working relationship with the team to get the results he has, so hopefully I will be able to pick up where he left off.”
McPhee has made three wild-card appearances so far this year - including at last month's Czech Grand Prix at Brno, where he eventually finished 15th after running as high as third in the early stages.
