Stefan Bradl wasn't getting carried away after setting the fastest lap time during Friday practice for the Czech Republic MotoGP at Brno.

The Honda LCR star, who claimed his first MotoGP pole and podium at Laguna Seca in July, knocked world champion Jorge Lorenzo from head of the timesheets by just 0.038s in the closing minutes of the second session.

The German had been just seventh in the morning session, then spent much of the afternoon outside the top five while running the harder rear tyre, before joining his rivals on the softer option to set his best time on the penultimate lap.

"We can be happy with this first place but I want to keep my feet on the ground," Bradl declared. "It looks good on paper but I am still not 100% happy with the bike setting and this is the reason why we have struggled in the first free session this morning.

"We need to work on the front part of the bike as we do not absorb the bumps as good as I want. I think we have more potential than this but we need to be more consistent tomorrow because the other guys will push to qualify in the front.

"The hard tyre is not so bad. The soft has more initial grip. It is maybe an option for the race. We need to try it some " he added of the two rubber options.

Bradl is currently sixth in the world championship, one place and 34 points behind top satellite team rider Cal Crutchlow.
