I put a set of 18 inch apes on my Heritage Springer,not only were they too tall,when you made a hard turn you almost hit yourself in the face from whichever way you were turning.I should have went with a 16 or smaller to begin with.I did purchase the bars from Hill Country Customs.If you need any info about them,service,etc.let me know.Was'nt a very plesent experince.
