There have been a large number of entries already confirmed for next year’s TT.
Race organisers haven’t specified exact figures but they say next June looks set for the biggest and best TT yet.
Qualifying starts on May 25 with sessions for the Lightweight machines followed by further session on the 27th and 31st.
The only significant change to the programme sees a third qualification lap added to the schedule for the TT Zero race.
Official race action gets under way on Saturday, June 1 with the Superbikes followed by the Sidecars later that afternoon.
Head of motorsport at the DED Trevor Hussey said he anticipated a significant growth in the Lightweight class and all the major teams from last summer were expected to return in 2013.
