Leon Haslam topped the unofficial timesheets at Portimao as a three-day test got underway with three manufacturers and nine riders in attendance.
Run in cool but sunny conditions, though times were not officially recorded, it was Haslam, fresh from a three-day test at Jerez, who was unofficially quickest on 1min 43.6secs, the Briton heading a BMW 1-2-3, with new team-mate Marco Melandri second on 1min 43.7secs and Italia rider Ayrton Badovini on 1min 43.8secs.
Aprilia duo Max Biaggi and Eugene Laverty followed up in fourth and fifth with identical rounded lap times of 1min 43.9secs, the pair just one tenth faster than top rookie rider Chaz Davies, once again on an Aprilia as it looks almost certain that his ParkinGO team will not compete with Ducati as originally predicted.
Further back, Michel Fabrizio set a time of 1min 45.5secs on the BMW Italia, while Leon Camier got his first taste of Suzuki machinery as Crescent Racing made its official WSBK debut, the Briton posting a time of 1min 45.8secs. Alastair Seeley was also on track for the team, replacing the injured John Hopkins, though no lap time was published.
