Yeah I never ran the stock bars on my 07 Road King. I installed a set of buffalo bars 1 1/2" and after putting 45k on the bars an HD tech suggested poly bushings for under the triple tree. As soon as the top clamp came off, the bars were cracked in 3 places between the knurling. The switch was expensive ($750) the first and second time because of the cruise and other wires in the bars. Not trying to scare you away from a good set of apes, but it's crucial to have the polyurythane bushings installed right off the bat, and of the utmost importance to decide on the RIGHT sized bars before you do the install. There's a site out on the net dedicated to the installation, laws and rights of the apehanger affecionados and other related topics. I still kick myself for not going with 18's instead of 16's. Hope this helps, Apes Forever!
