I know thisis an old post, but I thought I would put in my 2 cents worth. I to have the vibration as the RPM's increase. When cruising above 50 or getting on the bike to get to speed quickly the vibration is present as soon as the RPM's increase. The dealer I bought the bike from says this is normal. The srvicing tech owns a Venture and he rode my bike and says it feels like his. I have a 2008 Royal Star Tour Deluxe. It stands to reason there is vibration present when you take in to consideration the end weights on the handlebars are extremely heavy. I just hate the constant vibration in the footboards, but I find if I adjust my feet position I can get around it. As one reader said vibration can be subjective, what I consider vibration some may not.
