No, the 'mushroom' and the bar are much closer on the K12/13 pannier mounts. Though, with a bit of measuring, cutting and welding one could make them fit. There is a guy on the S1000R forum who mounted his K1300S panniers on his S1000R, he constructed his own mounting rail from a used F800ST/R rail that he purchased.
Cheers for that. Not something I can really do, so e-bay they will go.
