Johann Zarco increased the pressure and pace as bikes returned to the track for a final five-minute dash in qualifying for the Moto2 Czech Republic Grand Prix.
The Ajo Motorsport man came back with a new pole position record to steal a late pole ahead of Sam Lowes, as fellow title rival Alex Rins salvaged seventh after struggling in practice.
Zarco also took pole in Brno last season, when he went on to dominate the race, a feat he will aim to repeat after posting a supreme 2m 01.581s lap.
Lowes held the top spot for a brief moment following the restart, the Gresini rider ending the session just 0.033s behind the Frenchman.
The final front row spot will be filled by Alex Marquez, back on form at a track where he posted his best result in Moto2 so far. The Estrella Galicia 0,0 Marc VDS rider lead almost all the way to the red flag and still secured his first front row start in Moto2 with his early pace.
Taka Nakagami improved late on to move into fourth for Idemitsu Honda Team Asia.
Tom Luthi remains in fifth overall, the Interwetten rider suffered his second huge accident of the day - after his bike had already flew over the perimeter fence in FP3. The Swiss rider this time brought out the red flag after a highside at turn nine, hitting his head on the ground before being clattered by his spinning bike.
By the close of the session Luthi was on his way to hospital for further tests, but was reported to have remained conscious throughout, relieving worries after the fall.
The final row two spot went to Franco Morbidelli on the second Marc VDS entry, ahead of the much improved Rins, who after struggling all weekend pushed hard for seventh for the Paginas Amarillas HP40 team.
Danny Kent equalled his best grid sowing to date in Moto2 with a superb eighth for Leopard after looking to have a strong pace all through practice, the final row three slot is filled by Jonas Folger for Dynavolt Intact GP.
Simone Corsi put his Speed Up into the final spot inside the top ten while top rookie Miguel Oilvera just missed out in eleventh on the second Leopard entry– the race promises to be a competitive affair with the top sixteen all within a second of the pole time.
Lorenzo Baldassarri fell early in the session, his Forward Racing team had already had a massive repair job on their hands after his huge FP3 tumble, in 18th at the time the Italian had to play a waiting game, but his return to track paid no dividends leaving him 20th for tomorrows race.
