Why won't the RSD pipes of other BDM's fit? Has the motor changed to where the distance between the exhaust is different? I wouldn't think so but maybe some of these other guys can chime in and tell you. I would assume that all years with RSD from BDM would have the same distance between exhaust. The only thing you would have to list for the pipe manufacturer is soft/rigid and tire size. That sounds too damn easy, so you're probably right. It may be a completely different set up.Just wondering what pipes fit the new BDM bikes and what they look like. Has anyone put on the V&H Big Radius or the Martin Bros Pipes?
