“The TT will be a major part of Josh's 2013 season, for sure, but it is very much a learning year which should not distract his focus from BSB,” Neill said.
“Our main effort in road racing will of course focus around Guy [Martin] and possibly a second dedicated road race rider, should we decide to run a three-rider programme.
“However, Josh has a strong desire to race the TT which we had talked about many times before we finally made the decision to give him the opportunity.
“It really is hard to put any targets in place, although with a rider of Josh's ability and reputation, there will obviously be some expectation.
“I think Josh will be very realistic and from my experience he will only know after his first few practice laps if the TT really is for him or not.
“Either way, I expect him to treat his first year with careful consideration and examination and if he decides it is for him, then I see no reason why he won't excel at this discipline of racing in the same way he has on circuits.
“On the other hand, he may participate for one year and decide not to take his career in this direction, only time will tell.”
Conor Cummins rode for Tyco Suzuki on the roads this year but has been linked to several other teams.
Brookes is also in talks over competing at the North West 200 for the first time as a warm-up to the TT.
