Moto2 title leader Stefan Bradl, on pole for all three events this year and winner of two races, was fastest in both of Friday's free practice sessions at Le Mans.
The Viessmann Kiefer Kalex rider, quickest by 0.390sec over Thomas Luthi this morning, shot to the top in the closing seconds of the afternoon session - with Interwetten's Luthi then slotting into second, by 0.291sec, shortly after.
That double demotion pushed Ioda FTR rider Simone Corsi back to third, with home star Jules Cluzel (Suter) in fourth place, ahead of Jerez winner Andrea Iannone (Suter).
Reigning 125cc world champion Marc Marquez began his 50th grand prix weekend with sixth place for Repsol Suter. The young Spaniard is yet to finish a Moto2 race.
