We study the generalized SU(2){times}SU(2) Skyrme model, proposed by Cheung and Guersey, with an explicit chiral-symmetry-breaking term---the nonderivative pion mass term. We calculate the static properties of nucleons and compare with results obtained in the chiral limit. We find a peculiar behavior of the calculated proton and neutron charge densities, in the context of these models.
