The Monday after Jerez was the first chance that the teams and factories got to work on their bikes since the entire design was homologated ahead of the MotoGP season opener at Qatar. Given the oft-discussed weird start to the 2022 season, where the teams never seemed to have more than 5 minutes of normal or consistent conditions, having a whole day with a dry track allowed everyone some badly-needed time to work on some very basic stuff.
Of course, not everything was perfect. The weather was significantly cooler than it had been on Sunday, and the wind picked up considerably. There was also a nice thick layer of Michelin rubber, laid down in Sunday's race, the with the MotoE class, also Michelin-shod, adding yet more to the track surface. If anyone had hoped to work on low grip conditions, they would have to create them themselves by running very, very old tires.
Starting first with satellite riders – real satellite riders, that is, not the factory-backed riders in junior teams like Pramac – and rookies. When you have no new parts to test, then what you work on is setup, and especially the kind of setup changes that you don't have time to try during a race weekend.
