The first official grand prix track session of the 2011 season has been dominated by Nico Terol, during 125cc first practice for Sunday's Qatar Grand Prix.
Terol, who lost out on the 2010 crown by 14 points to Marc Marquez, is the highest ranked rider to remain in the two-stroke class and the Spaniard put his Bankia Aspar Aprilia on top of the timesheets by almost one second over Jonas Folger.
Folger has moved to reigning champion's Red Bull Ajo Derbi, with fellow German Sandro Cortese third for Intact-Racing Team Germany. Cortese was 1.3sec slower than Terol, with Luis Salom (RW Racing) and Efren Vasquez (Avant-AirAsia-Ajo) completing the top five.
The leading British rider was Folger's team-mate Danny Kent, in twelfth.
The unique four-night schedule for the Qatar event will see one further 125cc free practice session later tonight, another on Friday, then qualifying and (controversially) the warm-up on Saturday, before the race on Sunday.
