"After my podiums and fourth place in BSB Evo last year, this season I had a single goal and that was to be back on the grid," said Muff. "After conversations with different teams, Danilo Soncini of Supersonic Racing offered me the chance to ride in his team.
"I'm so happy because they have a strong technical background with the official support from BMW Motorrad Italia. I am totally aware of what a big opportunity this is for me and I'll do my best to achieve the results.
"It certainly will not be easy with the entry of riders like my team-mate Anthony West and Noriyuki Haga, the level of competition this year has certainly increased. However, I can't wait to sit on my new bike for the first time!"
The Supersonic team, directed by team owner Danilo Soncini, had announced their retirement from WSBK in September 2011. The team will be equipped with factory specification S1000RR machines, supplied by BMW Motorrad Italia and adapted for the new BSB technical regulations.
"I'm still excited about everything that has happened in these past two months," said Soncini. "The decision to leave racing had left an emptiness that I was unable to fill in any other way than returning to racing, then there was an opportunity to compete in BSB.
"The championship is really the ultimate expression of passion for motorcycling and to be able to compete as an Elite Team fills me with pride.
"Unfortunately the project started late and thus we will not be able to attend the first test rides at the beginnig of March as the bikes are still under construction at BMW. From April 9th onwards we will however, not be caught unprepared but ready to entertain and have fun! Thanks again to all."
