The lightweight class got set up for their first performance now that the circus returned home and Jerez welcomed them with warm brand new tarmac. Going by the final timesheets for FP1, the surface got predictably faster and the fastest of them all was John McPhee, who climbed into top position as the checkered flag was waved. The first home rider was a tenth and a half off, Aron Canet narrowly edging out Riccardo Rossi. The Gresini rider briefly led the way but missed out on one final fast lap as he crashed out in the very last minute of the session. Regardless, Rossi finished third and half a tenth faster that teammate Gabriel Rodrigo.
Dennis Foggia was an early leader but eventually settled for fifth position after a late flurry of fast laps, ahead of championship leader Jaume Masia. Kaito Toba, Jakub Kornfeil, Marcos Ramirez and Raul Fernandez completed the top ten but the likes of Lorenzo Dalla Porta and rookies Sergio Garcia and Ai Ogura also finished the session within half a second of the leader.
With the top 22 covered by just one second, many familiar names missed out on top positions, including Toni Arbolino in 14th or Darryn Binder in 16th. Romano Fenati was missing from the spotlight until he took a late off track excursion and could only grab 19th position, while Andrea Migno, who had led for most of the session, found the limit in turn three in the final ten minutes and failed to improve, dropping all the way down to 24th.
