We investigate properties of the nucleon and Δ(1232), in particular, the nucleon diagonal and off-diagonal electroweak form factors, in the framework of a πρω${\mathit{a}}_1$(${\mathit{f}}_1$) chiral soliton model, consistent with QCD. The effective meson Lagrangian reproduces known meson properties, and generally yields significant improvements over the πρω chiral soliton model for leading order baryon observables, in the ${\mathit{N}}_{\mathit{c}}^{\mathrm{-}1}$ expansion. The importance of the vector and axial vector meson physics in producing desirable soliton properties in the chiral soliton framework is demonstrated.
