Aleix Espargaro produced a blistering final lap in the dying seconds of afternoon practice to end day one on top at the British MotoGP at Silverstone.
The Aprilia Racing rider knocked Jorge Martin off the summit on his final lap, lapping six tenths faster than his Pramac Ducati rival.
Red Bull KTM’s Brad Binder made a big improvement from the opening free practice session in the morning, when he was 13th, to climb to third.
The 60-minute session was the sole chance for riders to seal their place in Qualifying 2 after a tweaked weekend format came into place at round nine of the championship this weekend.

Morning pacesetter Marco Bezzecchi, who was again at the forefront on the VR46 Ducati, suffered a big crash at Turn 7 on his out lap before he had a chance to complete his second time attack.
The Italian had led the way after his first time attack, bettering Maverick Viñales’ lap by two tenths with a 1:59.081s. Bezzecchi still finished seventh overall and goes straight into Q2, which is likely to be held in the wet on Saturday with rain expected at the British circuit.

Lenovo Ducati’s Bagnaia – last year’s British GP winner – made a big leap after languishing in 14th in FP1, slotting into sixth on the factory Desmosedici after a brief stint at the top.
Jack Miller was eighth on the Red Bull KTM behind Bezzecchi, with Luca Marini – second quickest in the morning on the VR46 Ducati – in ninth after a spill in the hour-long session.
Alex Marquez secured the final Q2 place in 10th on the Gresini Ducati, 1.15s adrift of Espargaro, with Quartararo next ahead of team-mate Morbidelli and Honda’s Marquez.
