Ducati managed to put 386 laps on its new GP11 bike as it made its track debut with a three-day test at Jerez, which concluded today.
Team manager Vito Guareschi returned to his previous role as test rider and was joined by Franco Battaini for the sessions.
Ducati's technical chief Filippo Preziosi was very pleased with the work Guareschi and Battaini achieved, but said it was only an initial step before race riders Valentino Rossi and Nicky Hayden are allowed to try the bike in the first group test at Sepang on 1-3 February.
"We're all satisfied with the work carried out, even though we're aware that we're dealing with technical solutions that were tried on a different track and in different conditions compared to those of Sepang," Preziosi said.
"Only when Valentino and Nicky have had their turn to try and evaluate those solutions will we be able to have a more certain confirmation and to understand if we've taken a step forward - and if so, how big a step."
