Ben Spies bolstered his hopes of a third consecutive Indianapolis MotoGP podium by setting the second fastest lap time in Friday practice.
The Factory Yamaha rider, yet to stand on the rostrum this season, moved from fourth in the morning to second in the faster afternoon session, as track conditions on the under used infield circuit improved dramatically.
Spies set a best lap just 0.285s from Repsol Honda Dani Pedrosa and is already satisfied with his race pace.
“The track definitely made a huge improvement from the morning to the afternoon today,” said Spies, who will leave Yamaha at the end of this year. “The bike is working really well, we made some small changes then just worked on race set-up.
“We used hard tyres for the whole time and were able to set our fastest lap and be consistent with a lot of laps on the tyres which is encouraging. We'll try the softer tyres tomorrow to see if we can pick up some speed for qualifying, but for the race set-up the bike is good.”
Team-mate and title leader Jorge Lorenzo was third fastest, but 0.719s from Pedrosa.
