In a surprising move, 2019 WorldSSP champion Randy Krummenacher had decided to part ways with CM Racing.
Having switched to the CM Racing team midway through the 2021 season, Krummenacher was scheduled to continue with the team into 2022.
However, the Swiss rider is instead looking for his third team in just the last year after previously starting the season with MV Agusta.
The decision is certainly an odd one as CM Racing - previously a Yamaha led team, have swapped to new Ducati machinery for 2022, while also expanding their team from a one-rider line-up to two.
Krummenacher was set to ride alongside former Moto3 rider Maximilian Kofler who signed for the team earlier this week.
Team Principal, Alessio Cavalieri said: "As Team Principal of the CM Racing Team, I respect the decision taken by Krummenacher, to whom I wish the best for the continuation of his career.
"For 2022, CM Racing will move to Ducati machinery with the V-Twin, with Austrian Maximilian Kofler in the team for his debut."
Ducati’s return to WorldSSP will be led by the full factory Aruba.it Ducati team and Nicolo Bulega, while son of former three-time WorldSBK champion Troy Bayliss, Oli Bayliss is part of the Barni Racing Ducati team.
It remains to be seen whether CM Racing will go forward with just Kofler, or whether a replacement for Krummenacher will be announced.
