Marc Marquez beat MotoGP championship leader Valentino Rossi to the quickest time in opening practice for the German Grand Prix at Sachsenring.
World champion Marquez topped the times with a lap of 1:21.766, outpacing his Yamaha rival by over three tenths of a second.
Scott Redding was a surprising third quickest on the Marc VDS Honda, with Marquez's teammate Dani Pedrosa fourth ahead of Yonny Hernandez on the Pramac Ducati.
Jorge Lorenzo finished down in seventh position on the second works Yamaha.
Marquez set the pace from the start with an early lap of 1:23.119 before being demoted by Rossi in a very busy first part of the session.
As the times continued to tumble, it was Lorenzo who took first place 10 minutes in, before Marquez beat his time just a moment later, setting a new benchmark of 1:22.182.
The Spaniard's time would be bettered by Rossi by 0.080s seconds before the halfway point of the session.
Marquez broke into the 1:21s with less than 20 minutes left, regaining first place.
The Honda rider went even quicker in the dying moments, setting a fastest lap of 1:21.766 that would remain unbeaten.
Pol Espargaro crashed at high speed 20 minutes into the session at Turns 10-11, the Spaniard emerging unscathed from the crash.
His Tech 3 Yamaha, however, was destroyed after rolling over the gravel several times.
Aprilia's Alvaro Bautista was next to crash at the tricky corner, the Spaniard losing his bike in the same way as his compatriot. Like Espargaro, Bautista was fine, but the bike was heavily damaged.
Michael Laverty, replacing Marco Melandri at Aprilia, finished in 23rd position.
Claudio Corti finished at the bottom of the times in his first outing for Forward Racing as he replaces the injured Stefan Bradl.
