The corresponding level 2 mode of the lightest Kaluza-Klein particle can be detected via KK number violating decays to Standard Model particles. The expected sensitivity to second level Kaluza-Klein modes of neutral gauge bosons at the ILC is studied.Talk given at 2005 International Linear Collider Workshop (LCWS 2005), Stanford, California, 18-22 Mar 2005High Energy Physics - Phenomenologytext
