Stefan Bradl will head into Qualifying as the favourite after a stunning performance in final practice for the Grand Prix of Qatar.
The German blew his rivals away with his lap time of 2:00.882 putting him ahead well ahead of nearest challenger Marc Marquez.
The 125cc World Champion was 0.872 seconds adrift with Andrea Iannone the only other rider within a second of Bradl.
Last nights' pace-setter Yuki Takahashi was fourth but failed to match his Thursday pace, with Scott Redding also going slower on day two to end up sixth.
The Brit endured a frustrating session as he struggled to find a clear lap, with traffic ruining his last-gasp effort when on a personal best.
Julian Simon had a much improved session after struggling with the windy conditions yesterday. The 2010 runner-up moved up to fifth after the chequered flag had fallen, just ahead of Redding.
Thomas Luthi and Jules Cluzel were next up with Moto2 proving every bit as competitive as it had in its inaugural year.
Behind Bradl, the next 16 riders were covered by just one second, a group that included Moto2 new boy Bradley Smith.
The Tech 3 rider was nearly half a second quicker than he had been on Thursday and has settled in nicely on his first weekend on 600cc equipment.
Kev Coghlan also made progress on his way to 28th place with a lap time four tenths quicker than yesterday.
After a strong pre-season Stefan Bradl entered this weekend as favourite, and the Viessman Kiefer Team rider has raised the bar with Qualifying scheduled for 15:55 GMT on Saturday.
