Motorcycling's governing body, the FIM, has announced that 16 new teams have applied to join the MotoGP field when the series launches its 1000cc rules package for 2012.
Existing entrants have been guaranteed spots in the field, but newcomers who are likely to be mostly from Moto2 – had to apply to teams' body IRTA by Friday this week.
An FIM statement said that the list of potential newcomers had now been whittled down, and candidates had a further two weeks to submit more details.
"IRTA has received submissions from 16 teams not currently participating in the MotoGP class," said the statement. "After reviewing the initial applications with Dorna it has been decided to provide further information to 14 teams containing 21 riders. Those teams will now be provided with a prospectus containing full details of the terms and conditions of participation.
"Teams who wish to proceed with their applications will then have until May 14 to submit comprehensive details of their plans for participation. These applications will be reviewed at Le Mans and teams will be notified of an acceptance, a rejection or pending status."
A final 2012 entry list will be published during the Catalunya Grand Prix weekend at the start of June after teams have lodged deposits.
