We investigate properties of the nucleon and [Delta](1232), in particular, the nucleon diagonal and off-diagonal electroweak form factors, in the framework of a [pi][rho][omega][ital a][sub 1]([ital f][sub 1]) chiral soliton model, consistent with QCD. The effective meson Lagrangian reproduces known meson properties, and generally yields significant improvements over the [pi][rho][omega] chiral soliton model for leading order baryon observables, in the [ital N][sub [ital c]][sup [minus]1] expansion. The importance of the vector [ital and] axial vector meson physics in producing desirable soliton properties in the chiral soliton framework is demonstrated.
