"I am doing my best to be in perfect shape for Sepang and am very excited to test my Ioda Suter. Anyhow I am facing this season with great enthusiasm and full commitment.
"I take this opportunity to thank Giampiero Sacchi and Came for this great opportunity, and all my fans in the Czech Republic for their affection and support."
Ioda has opted to run the standard ECU in MotoGP this year, meaning that Petrucci and Pesek will take part in the special test session this Sunday and Monday at Sepang, before the official three-day test begins on Tuesday at the Malaysian circuit.
Completing the 2013 Ioda line-up, and another new arrival, will be Moto2 rider Johann Zarco.
The former 125cc title runner-up finished tenth in last year's Moto2 series with JiR, enough to cinch the Rookie of the Year title, and will be aiming for his first four-stroke podiums in 2013.
Zarco is to steer a Suter chassis and takes over from Simone Corsi, who rode Ioda's FTR to five top-six finishes last season. Corsi has switched to Forward Racing in Moto2.
"I am very happy to be part of one of the best teams in the World Championship," said Frenchman Zarco. "I have had the chance to confirm the proven skills of their technicians already in Valencia during the testing sessions right after the last race.
"I went to Terni a few weeks ago and have visited their impressive race department, and realized that everybody at IodaRacing works with total commitment to racing. I don't deny that our main goal for this season is to fight for the top positions and for me to do my very best at all races.
"We will soon face the official tests where I will work hard to find a good feeling with my new Suter. I don't know my bike in depth yet, but I felt a strong sensation when I first rode it in the tests in Valencia.
"Since I am here with the sole intention of fighting for victory, I want to be on a good shape from the very first race in Qatar."
The first official Moto2 test of the year will be held at Valencia in mid-February.
Ioda has abandoned its Moto3 project.
