Factory Ducati team-mates Andrea Dovizioso and Nicky Hayden struggled to find a good set-up during day one of the Czech Republic MotoGP.

Both c♍omplained of a lack of grip on the fast, flowing Brno circuit, ending the day ninth (Dovizioso) and tenth (Hayden).

"The afternoon session was very strange, because we suffered a big loss of grip," said Dovizi🌜oso, whose best lap time was 1.2s from the to꧙p in both sessions.

"Honestly, I thought there was something wrong with my bi𝔍ke because I didn't expect such a big d♌ifference compared to this morning.

"We tried a number of things in an effort to understand if there was some problem, so we weren't able to follow the planned work proꦬgram for the session. Unfortunately, when t🌼he temperature rises, it affects us Ducati riders more than the others, and it becomes much more difficult to ride the bike well."

Hayden was a tenth of a second slower, and also in search of a Saturday breakthrough.

"It wasn't a very positive day. This morning we weren't so far off, 🍒but in the afternoon I struggled with a lack of grip, problems turning, and chatter. I also made some mistakes withౠ my riding and was running wide. Now we need to understand exactly where to go with the bike's setup and try to do a much better job tomorrow."
