After a poor weekend at Aragon, Ducati Alstare headed straight for a two-day test session at the fellow Spanish circuit of Jerez.
Former champion Checa, who finished just seventh and eighth in Sunday's races, and team-mate Aryton Badovini (two tenth places) took advantage of favourable weather to work through bike set-up options, focusing on settings and improving traction for upcoming races.
"These were two very important days that we used to better understand the bike's reactions," said Checa. "The weather helped us this time around too. We worked on different solutions for both the front and rear setting and in the end I'm happy with what we were able to get done. We've found a set-up that I like and this is important in order to have a good base from which to start at Assen."
Badovini added: "This test was key and allowed us to work on the bike and improve sensation. We've worked particularly on traction, to sharpen the bike on used tyres and maintain constant grip, which was my main problem at Aragon. We've tried different solutions and collected information that will be useful at Assen. I'm pleased with the work we've completed and look forward to next week's races."
No lap times were released.
Ducati Alstare will be back on track next week at Assen (26-28 April) for the third round of the 2013 World Superbike Championship.
