Keith Amor is to make a full-time return to the TT.
The 42-year-old Scot made an initial comeback last year after a shoulder injury forced him out of the sport in 2011.
Amor is being backed by RigDeluge and will have six bikes at his disposal for his challenges in the Superbike, Senior, Superstock and Supersport classes.
He will have 2015 spec BMWs for the bigger classes and a brace of World Supersport spec CBR Hondas for the 600cc races.
Amor will not compete in the Lightweight race.
The popular rider has yet to win a TT but has been on the podium five times.
