Team WFR has taken the decision to take a break from competing in both two and four wheel motorsport.
The team enjoyed a successful year in 2012, with Alex Lowes qualifying for the Showdown and finishing the season in fourth position. James Westmoreland finished seventh to win the Riders' Cup.
Team WFR Managing Director Myles Schofield said: "It’s been an extremely difficult decision and one that I have not taken lightly.
"I understand that it is very upsetting for everyone concerned, but I believe it is the right decision for the time and that it will give everyone involved with the team the best opportunity to move forward positively from the experience.
"It is not purely a question of budget, although it would be wrong to say that I could continue to run a similar programme to this year, there was certainly strong financial commitment to the Superbikes which could have resulted in another well-funded showing in BSB.
"Unfortunately, in combination with other circumstances, money alone just isn’t enough to do a season in BSB justice, and hand on heart I didn’t feel 100% certain that I was in a position to do my best – something I have always prided myself and my team on during my time in racing."
