The first day of the Portimao test is done and dusted, though calling it a test is a misnomer. The full-time MotoGP riders attended the test to learn the layout and to give feedback on the safety of the circuit. The MotoGP test riders are in Portimao to test tires for Michelin and help the French tire manufacturer put together the allocation for the race, and to figure out gearing and electronics at a circuit which is notoriously tricky for electronics setups.
All that means that the times are not particularly meaningful, a fact pressed home by the fact that most of the full-time MotoGP riders elected to ride without a transponder. The one point which may have some relevance is the fact that Aleix Espargaro - riding a MotoGP-spec RS-GP, as Aprilia have concessions and are allowed to test at any circuit still - was two tenths faster than Jonathan Rea's 2019 WorldSBK pole record, and 1.1 seconds faster than the WorldSBK race record, also held by Rea.
