Even with main rotor track and balance within spec it is still only a 2 blade main rotor. You are going to experience a bit of vibration, more than in a 3 or 4 bladed machine.
Nevertheless, go visit your local Robinson service center, have them fly with you, and see if they think it needs a fresh track and balance. With 60 hours on brand new components there is a bit of initial wearing in going on and that can affect the original track and balance.
