Fresh from their first win of the World Supersport season at Misano, Kawasaki came out fighting during first practice for the sixth round of the season at Motorland Aragon, David Salom leading Broc Parkes.
Capitalising on having tested at the new Spanish venue previously, Salom and Parkes occupied the top spot for much of the session as lap times dropped throughout.
Indeed, while Misano winner Parkes held the top spot into the final five minutes, it was local favourite Salom who would usurp him with a 2mins 02.416secs, just over a tenth quicker.
The pair were well ahead of the competition though, with Yamaha's Chaz Davies and Luca Scassa – returning to action his weekend following his forced absence at Misano – more than eight tenths adrift.
With lap times spread throughout the field, Sam Lowes was the only other rider to break 2mins 04secs in fifth position, more than a second ahead of sixth place man Fabien Foret.
Bogdanka PTR got their Aragon weekend off to a strong start with James Ellison and Pawel Szkopek in seventh and ninth, the pair split by Roberto Tamburini, while Massimo Roccoli rounded out the top ten.
