The analysis of the rotation curves observed along the bar of seven SB0 galaxies shows that they are characterized by a typical wavy shape. Among these galaxies is IC 456, for which new kinematical data are presented here. The possibility that this observational feature is typical of the stellar motions in bars is explored. Some interpretations of it as an indication of retrograde stellar streamings are also discussed, on the basis of the models of bars existing at present.
