    Using the surface photometric analysis data for a well defined sample of 79 nearby radio galaxies (z < 0.12), it is shown that the level of radio emission associated with an elliptical galaxy during the radio-loud phase is related to the presence of large amounts of isophotal twist in its optical image. In particular, radio galaxies with P_408 > 3 x 10^{25} W/Hz appear to show a preference to be associated with elliptical hosts exhibiting an isophotal twist in excess of ~20 degrees.Comment: 3 pages, 2 figures, in press in Astronomy and Astrophysic
