We investigate both, experimentally and theoretically, commensurability oscillations in the low-field magnetoresistance of lateral superlattices with broken inversion symmetry. We find that pronounced minima develop in the resistivity when the flat band conditions of several relevant harmonics of the periodic potential nearly coincide.
