I am running my bars as well without having changed anything ... I have fitted these bars on 07/57/09 and 2010 bikes and never needed to change anything ..... at most I have relocated the front brake line from the rear of the top yoke to in front of it ( more for looks than functionality) tho it seems some bikes have the brake line already in front of the yoke ( I guess it depends who put the bike together at the factory ) .... the only thing that has come to my attention is that some early 04/05 bikes have got a shorter brake line
