Hate to ask it, but want to know if anyone has some thoughts here. Love my 04 road king. Awesome color scheme and detailed the way I like it. Here's the deal. My wife has an MS family disease and the vibration flares up her condition something awful. S o I am wondering about a bike that would be virtually no vibration. I have tried all the Harley's at the local shop available for rental, but nothing is smooth enough. I really don't want to go gold wing, and not sure about BMW. I will keep the road king, but wondering if anyone has any experience or suggestion on options for a second bike.
