Andrea Iannone has suggested his departure from Ducati was partially down to some contractual issues he was not completely satisfied with.

Earlier this week the Italian factory announced that team-mate Andrea Dovizioso had been re-signed to partner Jorge Lorenzo next season, with Iannone subsequently named at Suzuki.

"Is a big, big change for me because for 2017 and 2018 I come to Suzuki. I'm very, very happy for this because I think is very important for me," Iannone said at Mugello on Thursday. "I'll be a first rider at the factory and Suzuki have shown a very good project.

"For sure after four years in Ducati, I've had some great moments and they have supported me since 2013. Thanks a lot for everything - I got my first podium in MotoGP with this factory and we are in a good moment. But okay, the future is different and for sure I'm very, very excited."

Pressed on his Ducati departure, Iannone added: "So Ducati decide in this way and for sure I have a possibility to remain in Ducati. But some part of the contract did not satisfy me at 100 percent. I want to change a little bit some parts, but this is not possible and I have a very good opportunity and proposal from Suzuki. For me in the end it is better I start this new adventure.

"Now I want to focus 100 percent on this season because we have a lot of races and it's very important to finish in a good way, good results because I think me and Ducati have a very good potential this year. For sure I want to continue to push at 100 percent."

Iannone - on pole at Mugello last season - has fallen out of three of the five races this season, while holding a podium place on each occasion.
