Heavy rain limited the action on the second day of MotoGP testing at the new Termas de Rio Hondo track in Argentina on Friday.
A group of four MotoGP riders have spent this week doing promotional duties in the country, which will host the world championship again from 2014 to at least 2016, with two days of testing to conclude it.
LCR Honda rider Stefan Bradl's 1m44.188s from Thursday will stand as the best of the session, as Gresini man Alvaro Bautista's Friday benchmark - achieved when the track dried late on - was 1.4 seconds slower.
"I think it perfectly suits the MotoGP machine but the big question mark are the tyres because the early indications indicate that the surface here is set to be extremely abrasive for tyres," said Bradl.
"I was happy with my fastest lap on day one but our main target was to get vital data for next year race.
"Unfortunately on day two the weather was not that good so I made only nine laps in the afternoon."
Tech 3 Yamaha's Cal Crutchlow and Avintia CRT rider Hector Barbera completed the MotoGP contingent, while Tito Rabat and Nicol Terol tried out the venue on behalf of Moto2.
