Mecan and root rotation in X, Z axis (pitch and roll)

I was trying to play a generic animation (non-human one) and the root node has rotation in X and Z axis. When I play it using Mecanim, the rotation is lost. I suppose that, as it is mainly for human bodies, it only manages root rotation in Y axis (yaw).

Is any way I can get my animation working?

Thanks in advance.

Have you attempted to play with Baking settings in Animation Import?

Does your model turn physically in the Modelling software (requirement for root motion). If not refer to this page.
