Moto2 rookie and double race-winner Marc Marquez led both of Friday's free practice sessions for the Italian Grand prix at Mugello.
After spots of rain during second practice for 125cc and MotoGP, Moto2 enjoyed bright sunshine and a dry track for most of their afternoon session - although dark clouds began forming towards the end.
Reigning 125cc world champion Marquez, now up to second in the Moto2 standings, was 0.319sec ahead of title leader Stefan Bradl - and 0.121sec quicker than the German in the faster afternoon session.
Bradl, who suffered his first DNF of the season last weekend at Assen, popped into second on his 15th and final lap of FP2.
That pushed Sammarinese Alex de Angelis down to third for JiR, with last year's runaway home winner Andrea Iannone the top Italian in fourth (+0.281sec).
Scott Redding enjoyed an encouraging start to round eight with fifth this afternoon for Marc VDS Suter, with last year's 125cc stars Pol Espargaro and Bradley Smith sixth and seventh.
Bradl, winner of four of the seven races so far this year, will start Sunday's race with a 57-point lead over Marquez.
