Iannone, who replaced Yamaha-bound Maverick Vinales for 2017, has so far been unable to match the Spaniard's 2016 success.

The Italian has only scored 28 points compared to Vinales's 83 this time last year.

During the summer break between Sachsenring and Brno, Suzuki announced a new project leader in Shinichi Sahara, and Iannone is adamant the team is now primed to return to winning ways in the future.

"There were some changes at the top in Japan, when that happens, you have to reorganise everything to sort the situation," Iannone said on Thursday at Brno.

"I'm convinced they are working hard and I'm sure we will [come back]. On this, I put my balls on the line."

"A big step forward"

Iannone had concluded the first half of the season with a crash at the Sachsenring, his third retirement in nine races.

However, he revealed he "made a big step forward" during the German round in terms of feeling with the GSX-RR bike, and reckons it can be "even better" at Brno.

"My feeling at Sachsenring was pretty good, we made a big step forward from Friday to Saturday, I had a great feeling with the bike.

"Regardless of any updates, I think I can have an even better feeling here [at Brno].

"The important thing is that I and Suzuki have a very important and strong relationship, which gives me so much confidence."

Iannone kicked off the Czech Grand Prix with a 16th place in the opening wet practice.
