  If the lowest lying Kaluza-Klein states in Randall-Sundrum (RS1) models have
masses in the 10-100 TeV range, direct production of these states at the LHC or
ILC is impossible, and electroweak precision measurements may not be
sufficiently sensitive. We address the possibility that high-precision
measurements of top pair production at the ILC may provide the first evidence
of these states. We consider RS1 models with fermions on and off the brane,
with bulk left and right handed mass terms, discuss brane kinetic terms and
calculate corrections to top pair production in these models.
