As rumoured at Silverstone, Sam Lowes will return to the Moto2 World Championship using a KTM chassis in 2018.

The Englishman signed for the Interwetten squad after losing out on the second year of his Aprilia MotoGP contract, but with the chassis still to be officially announced.

However Interwetten team manager Fred Corminboeuf confirmed to MotoGP.com at Misano that a deal has now been done to switch from Kalex and become KTM's first satellite Moto2 team.

"Yes, this is official today," Corminboeuf said. "We've signed with KTM. We are really proud to be involved with the KTM family. I used to work with them also in motocross in the past and it's a really great family.

"It's a new challenge for us, but we have no problem with Kalex. We have won races and fought for the championship with Kalex. It's a great bike. Until the end of this season we will be Kalex guys and fight for this title."

With current star rider Thomas Luthi stepping up to MotoGP next season, Corminboeuf revealed that Iker Lecuona will be retained alongside Lowes, but that the third machine for Jesco Raffin is unconfirmed.

"We are proud and happy to say Sam Lowes will be with us," Corminboeuf said. "Iker Lecuona will stay, he is improving race-by-race now and he will be tough next season.

"The third rider, to be honest, I don’t know. It's a little bit difficult now for Jesco Raffin to make some points and be in front. He has a good potential but has had a lot of problems.

"We need to decide if we can bring Jesco to the front and, if not, we will see what we can do."

Corminboeuf's CGBM Evolution company runs both the CarXpert Interwetten (Luthi) and Garage Plus Interwetten (Lecuona and Raffin) Moto2 entries.
