After the rain scare earlier today, Jerez was back to its sunny self by the time qualifying got underway in the lightweight class and it allowed Deniz Öncü to continue his dominance around the Spanish track, taking pole position by a tenth of a second. The Turkish rider had no match but his closest challenger was the most successful of the Q1 graduates - Ivan Ortolá escaping Q1 by the skin of his teeth but going on to claim a front row start. There he will be joined by compatriot David Muñoz, although the BOE rider ended the session with a rapid tumble at the final corner, meaning he could not join parc ferme to celebrate his first front row start. Assuming the Spaniard is fit to take the start tomorrow, he will have to overcome a double long lap penalty for causing a crash at COTA.
The extra practice in Q1 gave Romano Fenati the upper hand early in Q2 but the Italian was eventually demoted to fourth – still a best qualifying result of the season so far. Jaume Masia flew under the radar throughout qualifying, steadily climbing up the timesheets and could have done better than fifth, had it not been for some late yellow flags. Ryusei Yamanaka will be joining the two veterans on the second row of the grid, while championship leader Dani Holgado opens row three, ahead of Ayumu Sasaki and Xavi Artigas.
Rookie Jose Antonio Rueda completes the top 10 and is joined by Scott Ogden and the returning Joel Kelso onto fourth row. Kaito Toba starts row five, while Diogo Moreira will need to do some damage limitation work after escaping Q1 but struggling to keep within track limits on his fastest lap, which dropped him to 14th on the grid, ahead of Andrea Migno.
