A primary optics for a motorcycle headlamp, wherein the primary optics is a non-imaging primary optics configured to irradiate a segmented light distribution in front of the primary optics, wherein the primary optics includes a plurality of light guiding elements for forming a predetermined segmented light distribution from light of light sources in a main direction. Each light guiding element has a light input surface and a common light output surface, wherein the light guiding elements are arranged in groups, wherein each group includes at least two light guiding elements arranged in juxtaposition along a straight arrangement line orthogonal to the main direction. The light segments generated by the light guiding elements of a group are irradiated in juxtaposition along a straight irradiation line corresponding to and parallel to respective straight arrangement line of the respective group. The common light output surface includes a homogenization structure, which is formed of a plurality of grooves, each of which extends along an extension line transverse to the straight arrangement line of each group of light guiding elements, wherein the groove has a constant radius in a cross-section orthogonal to the extension line along the extension line, and wherein the grooves are arranged with respect to each other such that the extension lines of the grooves are parallel to each other.
