MotoGP manufacturers will be able to hold a maximum of five days of private testing with their race riders, from next season.

"Manufacturers are permitted to nominate one circuit at which they may test with their contracted riders for a maximum of five days during the season," said an FIM statement, following the latest meeting of the Grand Prix Commission at Indianapolis.

"This will enable them to develop and test new technology with their principal riders in a private test environment."

The Commission also clarified the format of factory teams in MotoGP next year, after speculation - following a previous announcement - that the present two-rider factory team limit could be abandoned.

The FIM has clarified that this is not the case and that the format of two factory team riders, plus two satellite team riders, will continue - albeit with allowances for the new privateer machinery, running the full standard ECU system.

"Manufacturers will be permitted to make two direct "Factory" specification entries in their own team and to lease Factory specification machinery for a further two [satellite] entries.

"They may now also lease machinery for additional entries. These machines will run under the non-Factory [privateer] regulations for the class."

The Commission also announced that Yamaha test rider Katsuyuki Nakasuga will have a wild-card ride at Motegi.
