The latest MotoGP rule amendments, announced by the Grand Prix Commission, reveal a switch back to four MotoGP practice sessions of one hour in length, plus grid changes and a restriction on GPS technology in MotoGP.

GPS is used to accurately locate each motorcycle on the race track in real time and therefore allows set-up to be tuned for each corner.

Other, more detailed, rule changes were announced for the Moto3 class from 2012 (see separate story).
