The Grand Prix Commission has announced several rule amendments for 2016, mostly concerning the compulsory standard ECU system and associated removal of the MotoGP Open class.

The statement confirmed that each manufacturer is allowed one sensor that is not available to all other teams. However, "data from this sensor can only be used for datalogging purposes and cannot have any effect on control strategies." All other sensors must be homologated.

The testing regulations have also been amended to reflect the end of the Open class:

"Manufacturers with their own teams will be permitted to test with their contracted riders for a maximum of five days at any circuit as opposed to just one nominated circuit. They will continue to be permitted to test with test riders using the test tyre allocation.

"Lease Teams, who are currently restricted to just testing with test riders, will now be permitted to test at any circuit for a maximum of five days with their contracted riders. However, additional testing with test riders is no longer permitted.

"There are no changes to current test restrictions for Concession teams.

"For all classes, permitted private testing is in addition to testing at official tests organised by Dorna and IRTA. Also, existing regulations that forbid testing between 1st. December and 31st. January, or within 14 days of a race at the same circuit, are unchanged."

Meanwhile, testing opportunities will be tightened for the Moto3 and Moto2 classes.

"Currently Moto3 and Moto2 riders are restricted to testing at two nominated circuits, one GP circuit and one non-GP circuit, albeit at any time. This has led to situations where some better funded riders have been testing almost constantly. There have also been problems for teams to secure testing dates when there is limited availability at some circuits.

"In future riders will be able to test at any circuit for a maximum of ten days."
