Supersonic Racing has confirmed it will not return to the MCE British Superbike Championship this year, the team instead favouring a return to its native Italy for 2013.
After two years competing in the World Superbike Championship as a privateer Ducati outfit, Supersonic made the switch to BSB in 2012, entering a pair of BMWs for Tommy Bridewell and Patric Muff.
Going on to prove one of the year's revelations, Bridewell and Supersonic caused a stir by making it into the 'Title Showdown' before eventually concluding the year with sixth position in the riders' standings.
Even so, despite its success, Supersonic had made no secret of its frustration over BMW's reluctance to increase its support for 2013, raising doubts over whether it could afford to compete in BSB this year.
With no deal forthcoming, Supersonic has now confirmed it will compete in the Italian-based CIV Superbike Championship this year instead, entering a Suzuki GSX-R1000 for former Italian champion – and occasional BSB rider – Alex Polita.
As well as leaving Bridewell without a ride, the announcement means two of the six teams that made it into the 2012 BSB 'Title Showdown' – Supersonic and Team WFR – will not be present on the 2013 grid. MSS Performance has also announced a sabbatical for this season.
