I thought it was just me. My 06 rocket does the same thing I notice once I get over about 60 to 65 I get a vibration that just starts from no were. Low speeds it is smooth.I just figured it was do to those big pistons once they got to a certain Rpm the caused a resonance that you feel threw the bike.
I should try and hook up my vibration analyzer and see what I get.
My wife has a vibration analyzer but I took her batteries........................
