Reigning World Superbike champion Carlos Checa is testing Ducati's GP12 MotoGP machine this week in a private session at Jerez, but team bosses have put the kibosh on any public comment - even on the new window to riders' minds, Twitter.
Checa was reported to focus on the handling of the redesigned, aluminum-frame machine, according to media reports.
The only comment on Checa's Twitter feed, @CarlosCheca7: "1st test this year recovering good feelings on bike, we are working well. I can't say so much, tomorrow more work. Ciaoo!"
While Checa was muzzled, Ducati mechanic Alex Briggs - who works on Valentino Rossi's bike -- stressed on Twitter how different the GP12 is compared to its much-maligned carbon-fiber predecessor, the GP11 and its variants.
Briggs tweeted: "The test in Jerez is a major check and to get a base setting, for everything. The bike we [assembled in Bologna recently] is NEW. This sort of thing would normally have been built & testing started about June [last year]. It's major! Ducati have done an awesome job in the time since the Valencia test. The factory has been flat out & it's not over yet."
Testing will continue through Thursday. Ducati test rider Franco Battaini also is aboard the new bike, which will be unveiled publicly during the first preseason test Jan. 31-Feb. 2 at Sepang.
