Nico Terol continued his early dominance of the 125cc World Championship by setting the fastest time in First Practice at Jerez.
The Spaniard blew the field away in Qatar two weeks ago and moved to the top of the timesheets in the closing minutes with a lap of 1:48.384, to edge out Sandro Cortese.
The Intact–Racing Team Germany rider was Terol's nearest challenger throughout the opening weekend and proved to be again on Friday morning, albeit 0.619 seconds adrift.
Efren Vazquez had held the fastest time since the halfway point in the session as he became the first man to go under 1:50, but as his rivals found time, he slipped to third.
Bankia Aspar's Hector Faubel took fourth but will be concerned both with the 1.155 seconds gap to his teammate at the front, as well as a brief trip through the gravel trap.
His lap was still good enough to place him ahead of Jonas Folger, who took fifth for Red Bull Ajo Motorsport.
Pev-Blusens-SMX-Paris-Hilton riders Sergio Gadea and Maverick Vinales were next up. Gadea will be looking to build on his podium finish in Qatar while his 16 year old teammate will fancy his chances as the reigning Spanish 125cc Champion.
The best of the Brits was Danny Kent once again. The Chippenham rider took a very creditable ninth, and was only 0.435 away from teammate Folger.
Danny Webb will be happy with 15th for Mahindra Racing as the team goes in search of their first World Championship points, while Taylor Mackenzie also had a positive morning.
The Scottish teenager raised eyebrows after 15 minutes when he set the second fastest time behind Terol, but he dropped down the order as others improved to finish 18th. The fourth Brit in the field, Harry Stafford, was 26th.
