Scott Redding led the Ducati challenge with sixth place on the Friday practice timesheets in Argentina.

The Pramac rider - who set a best lap time 0.879s from Honda's Marc Marquez - admitted enjoying sliding his GP15 around the slippery Termas de Rio Hondo circuit, but knows staying on his toes and adapting to the changing grip will be key this weekend.

"Here the feeling is not bad and I can improve. The track is in quite bad condition but I'm having fun. I'm enjoying sliding a lot. It's a positive way to go. This weekend maybe we can improve a bit from Qatar which is my target," Redding said.

"I have a good feeling with the bike but still have not found the right confidence with the tyres. We have improved working a bit on set-up, but I don't want to change the bike too much as the circuit conditions are constantly changing.

"With the new tyres things go well, especially under braking, but after 2 or 3 laps the grip drops very much and the risk of losing the front is high. You can close the front quite easily."

Redding rode from twelfth on the grid to tenth during his Ducati debut in Qatar and is seeking at least a top-nine start in Saturday's qualifying, when rain could also be a factor.

"My target for tomorrow is obviously to go through to Q2 directly and improve on my qualifying from Qatar. Starting on the first two or three rows would be really good and give me a better chance in the race."

The next best Ducati rider after Redding was factory star and Qatar runner-up Andrea Dovizioso, in tenth.
