I saw someong mention that stock bars are stainless..... I changed my Nightser's bars over to stock Dyna Wide Glide mini apes, not sure of what year or part # off the top of my head, but they are almost the exact same bend as the black mini apes that EVERYBODY puts on a Nightster, so I wanted to be different...... I had 4" risers on before, and I had to change my brake line to a braided stainless line. The brake line is usually the only component that won't work out when you change bars to anything taller. I went with a braided stainless piece from Dennis Kirk, cheaper and better than a Harley piece, and it gave me the flexibility to change my bars to whatever I wanted. My stock wires and clutch cable worked fine with the new bars, and even though I recently relocated my turn signals from under the grips to the bottom of the trees, there was enough wire to make it. I'm pretty sure most HD's are that way, you might have to re-route the wires a bit, but they should make it to the grips, unless you are going with the ultra high apes or the super wide beach bars (my favorite on a RK are super wide and flat beach bars, I'm 5'10 300#) hope this might help.
