Ducati's Nicky Hayden was seventh fastest on his Desmosedici GP13 on the first day of practice at Catalunya in Spain, with the popular American rider admitting the result 'wasn't spectacular'.
Hayden is struggling to put together fast times once he loses grip and will devote his energy tomorrow to preserving the longevity of the Bridgestone rubber over a race distance at the Spanish circuit, where high temperatures are having a huge impact on tyre choice.
“It wasn't a spectacular day but it wasn't a disaster either compared to some of the other Fridays,” Hayden said.
“In the end we were half a second off, which is a lot but a lot closer than we've been in the last couple of Fridays.
“A couple of tenths would have put us well into the top five but the main problem is making the tyre last better.
“Once the tyre drops we have a lot of little problems but... most of the changes we made worked better,” he added.
“The big thing is tyre wear, especially for us and we spend a lot of time on the edge, so it's going to be a tough race, that's absolutely sure.
“We have two tyres to choose from and it's not like the old days when you had five or six tyres to choose from, so we'll have all day tomorrow to see which tyres lasts.
“Everywhere we've been using the soft on the rear but this weekend is the first hot race so maybe the hard [compound] will be a player.”
Hayden set his quickest time of 1m 42.890s in FP2 in the afternoon to leave him 0.593s down on the fastest lap achieved by Yamaha's Valentino Rossi but only 0.093s behind Repsol Honda's Marc Marquez in sixth.
His best time put him ahead of team-mate Andrea Dovizioso by 0.098s.
