Every Road King needs a crown. Having a 18" or 20" rise could get tiring after a long ride, that is why our Maddogger slopes down to a 16". It offers the look of a high rise with the comfort for long rides. The Maddogger is most popular on Road Kings and Softails. The 1-1/2" diameter only adds to the aggressive look. Factory 47 only offers the best in quality, comfort and looks.
