KTM's extensive testing programme ahead of its 2017 MotoGP debut continued at Jerez, with randy de Puniet re-joining main test rider Mika Kallio.

Back on track less than a week after testing at Brno, tropical conditions greeted the RC16 riders during their two days in Andalusia.

Michelin also provided tyres for the first time, which technical director Sebastian Risse were 'very similar' to those used in Spanish Grand Prix.

"Our focus here was mainly on being able to confirm the development steps we made in Brno. However, the conditions, especially on day one allowed us to shed light on how our material would work under extreme conditions, and we had no big problems," Risse said.

"We also had tyres from Michelin for the first time, which are very similar to those used in the Grand Prix on this circuit. Because of this we were able to work on the setup in different ways, and we saw a significant improvement in laps times compared to those from the earlier tests [here] in [February]."

"The bike behaves on the track more and more as I would like it to do," declared Kallio. "It wasn't so easy for us to take big steps in the past couple of months and that makes it all the more important that the lap times are now coming.

"This is also good for the team's motivation. I think we have made the decisive further development just at the right time, before we shortly test ourselves against the competition."

KTM's next test will be held in Italy in two weeks' time, 'with another new test rider'- expected to be multiple Moto2 race winner Thomas Luthi.

Bradley Smith and Pol Espargaro are now confirmed as KTM's 2017 MotoGP race riders, with Kallio continually as main test rider.
