GNS Racing, the 2010 British Supersport championship-winning team will not be racing this year.
Team owner Gary Stubbington has made the reluctant decision to sit out the season after failing to raise a sufficient budget.
The Southampton-based team, owned and run by Stubbington, convincingly won the Fuchs-Silkolene British Supersport title with Sam Lowes in their debut season, and scored World Supersport Championship points at Silverstone.
The team were hoping to move into BSB Evo this year but Stubbington revealed: "Whilst we have done our best to try to raise the necessary funding, there is simply no point going racing if you don't have the budget.
"Both Sam and the team did a wonderful job last year and I'd like to take this opportunity to thank them as well as our sponsors. We hope to be back in 2012.”
