Factory MotoGP teams will no longer be able to sign rookie riders from 2010, under the new regulations announced at Jerez today.
The move is intended to encourage the most talented young riders to begin their MotoGP careers at the smaller teams, in the hope that the satellite squads can achieve better results and earn more sponsorship as a consequence.
FIM president Vito Ippolito confirmed the introduction of the rule in a press conference during today's Jerez test.
"For next year we will have some regulations for the entry into MotoGP," he said.
"It means that new riders coming from other classes and other championships will not be allowed to participate with a factory team. The new riders from the 250cc class, or Moto2, or other championships arriving into MotoGP will only be allowed to participate with private or satellite teams."
Jorge Lorenzo moved straight into the factory Yamaha team as 250cc champion in 2008 and proceeded to take three straight pole positions and win in his third MotoGP start.
However the Spaniard was relatively unusual, as most rookies in recent years have started with private teams anyway. Lorenzo was the only one of last year's newcomers to get a factory ride, with fellow rookies Alex de Angelis, James Toseland and Andrea Dovizioso starting out with Gresini, Tech 3 and JiR Scot respectively.
Of the current front-runners, both Valentino Rossi and Dani Pedrosa were signed by the works Honda team straight from 250cc, but Casey Stoner had a learning season with LCR Honda before joining Ducati and taking the 2007 title.
