Nico Terol remains unbeaten in the Qatar Grand Prix weekend after showing his rivals a clean pair of heels in the 20 minute warm-up.
The pole-sitter was in a class of his own from the moment he took to the track, with his time of 2:06.840 only narrowly slower than his own pole position lap. This time, his nearest challenger was his Bankia Aspar teammate Hector Faubel, who matched his time from earlier in the evening to snatch second.
He edged ahead of Sandro Cortese with his last hot lap of the session, with the German finishing third ahead of Alberto Moncayo.
Adrian Martin produced his best performance to take fifth, with all three Bankia Aspar Aprillias showing good pace.
Efren Vazquez, who will complete the front row tomorrow alongside Terol and Cortese, had a quiet session and ended it in tenth.
British honours went once again to Danny Kent, although he was only 15th. Danny Webb followed closely behind in 16th, despite an accident during the session.
Mahindra Racing team will have been encouraged by a time that was a quarter of a second under Webb's qualifying best, but off-track excursions for him and teammate Marcel Schrotter won't have been in the script.
Taylor Mackenzie took 22nd while Harry Stafford got his weekend back on track. After a nightmare qualifying session the rookie finished the warm-up in 26th, shaving nearly a second off his time from earlier in the evening.
The riders will next take to the track for the first race of the 2011 125cc World Championship. The race is scheduled to start at 16:00 GMT on Sunday.
