Former world sidecar champions Ben and Tom Birchall have made winning a TT their "top priority."
The brothers from Mansfield will compete at this year's event for three-time TT winner Klaus Klaffenbock's new Cofain Racing by Klaffi team.
They made their TT debut in 2009, the same year they won their world title.
Tom, 25, said: "A major goal of ours is still to become two-time world champions but for now we are focussed completely on winning a TT."
Austrian Klaffenbock, who claimed all three of his Mountain Course wins with Manx passenger Dan Sayle in the chair, set-up his new team after announcing his retirement from racing in September.
The 2001 world champion said: "We watched Ben and Tom in 2009 at their first TT and again in 2011. These two guys have the potential to win."
Last year the pair finished seventh in the opening sidecar race and fifth place in the second, clocking their fastest lap at 111.622mph.
Ben Birchall said: "Both Tom and I are honoured to have been asked to join Klaus in his new venture."
The 35-year-old added: "He has brought in some really good people and we are extremely honoured to get the ride."
The team will also feature another sidecar world champion in Adolf Hanni.
