Alvaro Bautista and Suzuki recorded their best dry finish of the season with sixth place at Indianapolis on Sunday.
Starting ninth, Bautista got a good start and was in seventh at the end of the first lap.
The Spaniard then got involved in a battle with home stars Nicky Hayden and Colin Edwards, finishing almost nine-seconds clear of Edwards at the flag.
"I was consistent throughout the whole race and had a couple of good battles with other riders – especially with Edwards – but at the end I got a good rhythm and was able to get some distance on the riders behind," said Bautista. "I think today was the best result we could have got – so we did the maximum."
Edwards was impressed by the GSV-R's engine performance.
"That bike has got quite a bit of grunt off the corner," he said. "Just when I would make up the work and get to him, he'd pull 10 bike lengths on the front straight."
Bautista finished 30sec from the Honda of race winner Casey Stoner, 20 seconds from the best Yamaha, but 23 seconds ahead of the leading Ducati.
“I don't think this is one of the best tracks for us and we were only beaten by the three Repsol Hondas and the two factory Yamahas," said team manager Paul Denning. "This bodes well for the rest of the season, and we're looking forward to Misano.”
