My bars are not comfy and have been looking at Wild1 chubbys. pullback on mine are 12" , but i want more and a higher bar. probably a 10'. don't want to replace any cables or brake line. they don't recommend the 575 or 578 because of 14" center width for road kings. they are for baggers though. i like the 518, but is lower than my bar. anyone using 575 or 578 on a road king?
