Sidecar World Champions in 2009 Ben and Tom Birchall will be racing at TT 2011.
The Mansfield based brothers made their debut around the mountain course two years ago, when they were forced to retire on the final lap of the solitary race while lying in sixth place.
However, a lap of 110.615 miles an hour showed their potential, putting them in 14th place on the list of all-time fastest sidecar crews.
The pair reluctantly had to withdraw from last year's races because of a lack of sponsorship and suitable machinery.
Ben Birchall says he is thrilled to be back racing at the TT:
Boxing: November fight date confirmed for Sam Rennie
Cricket: Lucy Barnett named August ICC Women's Player of the Month
Shooting: Kirkpatrick takes the win by one
Powerlifting: Isle of Man to begin Commonwealth championships campaign
