Bradley Smith says he felt 'instantly comfortable' in the wet conditions at Brno as the British rider set the fastest sector times of all the Yamaha riders in the first half of the circuit in FP2.
Smith, who has penned a new deal with the Monster Yamaha Tech 3 team for 2015, was ninth quickest in the afternoon session and 10th on the combined times following the dry morning practice run.
The 23-year-old is positive over his pace in the damp at Assen, with more rain predicted for Saturday's final Czech MotoGP free practice and qualifying.
Smith, whose best time of 1m 57.816s was 1.013s off the quickest lap set by Repsol Honda's Marc Marquez, said: “In the afternoon session I was instantly comfortable on the wet surface and my lap times were comparable to the other riders who stayed out for nearly 30 minutes.
“The track eventually started to dry and I didn't push right on the limit straight away as the aim was just to obtain some more valuable data.
“This is especially useful as it looks like there will be more mixed conditions tomorrow, but overall I am pleased with what we achieved today.”
Smith, sixth last time out at the Indianapolis MotoGP, says he also has a clear direction to pursue with the set-up of his satellite YZR-M1 on Saturday.
“All in all it was a good day for me today, even though the conditions were mixed. Overall, I'd say that we have been lucky with the weather so far this year, but we must always expect the rain to come at some point as it did today,” he said.
“In the morning I tried both bikes and we now have a very clear direction of which way we want to go in terms of a dry set-up as I was clearly able to undertake a much quicker pace in the final run this morning, so we will continue with this set-up.”
