Inbound write up 'Eng N1 vib 7.7 on T/O climbout varied between 4.0 and 7.7. At cruise varies 1.4 to 3.0 Maintenance accomplished Task 77-32-00-810-807-A; No damage found; everything secure.' During takeoff prior to 80 KTS call my First Officer called out N1 indication of 8.7 (we discussed during our briefing if above normal Flight Operations Manual (FOM) range of up to N1 of 5.0 we would abort); rejected takeoff engaged and we notified Tower of our abort. Wheel brakes did not exceed 420; so we elected to taxi to the gate.
Air carrier Captain reported rejecting takeoff when N1 vibration exceeded normal limits.
