Nicolas Terol once again showed his superiority in the 125cc class by comfortably setting the pace in second practice at Le Mans.
The Bankia Aspar rider was only a tenth of a second clear of Efren Vazquez in the morning session but increased that to over half a second in the afternoon.
Terol set two separate lap times which would have put him ahead of the rest of the field, his quickest was a 1:43.788, a fraction slower than the lap record around the Bugatti circuit.
Vazquez was 0.584s back in second for Avant–AirAsia–Ajo but was forced to return to the pits on foot after crashing the Derbi on his final lap of the session.
Sandro Cortese moved up to third in the afternoon and was a hundredth of a second behind Vazquez as he continues to lead the chasing pack behind Terol.
Luis Salom momentarily leaped up to fourth as the chequered flag fell but the RW Racing rider was shuffled back to sixth as Hector Faubel and Jonas Folger both made last minute improvements.
Maverick Vinales was seventh but had also featured in the top four earlier in the session as he upheld honours for Blusens by Paris Hilton Racing. Teammate Sergio Gadea was unable to do so and didn't set a competitive time until the final quarter of an hour, ending up in 14th.
Home favourite Johann Zarco was eight fastest with Alberto Moncayo ninth and Adrian Martin completing the top ten on the third Aspar Aprilia.
Danny Kent improved on his morning effort to go 16th with Harry Stafford in 23rd place. Taylor Mackenzie's return from injury continued with the 23rd fastest time.
Mahindra Racing had a nightmare session with both bikes ending up in the gravel trap. Marcel Schrotter crashed out before with thirteen minutes to go and Danny Webb did likewise with five minutes left on the clock.
The Kent rider had already encountered problems at the start of the session when the GP125 wouldn't return to the garage under its own steam, and he had further problems when he lost control with smoke pouring from the rear of the bike.
